eChapters

The selection and management of ingredients are fundamental to producing consistent, safe, and high-quality ice cream. This chapter provides an overview of the principal ingredients used in ice cream mixes and explains their selection criteria, approximate composition, functionality, storage requirements, and handling practices. It considers dairy ingredients, sweeteners, stabilizers, emulsifiers, flavours, colours, inclusions, and other formulation components. Ingredient quality directly influences processing performance, sensory properties, shelf life, and product cost. The chapter also highlights incoming-material quality checks and common ingredient-related defects. By understanding ingredient functionality and quality specifications, manufacturers can improve formulation accuracy, process consistency, product performance, and overall manufacturing efficiency.

Fermentation

The term fermentation is loosely used to denote any process in which microorganisms are involved, regards of whether or not the organism is growing in the presence of molecular oxygen. Thus, it can be defined as 'an ATP generating metabolic process in which organic compounds serve both as electron donor (becoming oxidized) and electron acceptor(becoming reduced). Energetically, fermentations are poor energy yielding process and products have lower energy content then the substrates. Since there is no net oxidation in fermentation, the number of molecules of C, H and O remain the same in products as in the substrate.

Mixed farming exists in many forms depending on external and internal factors. External factors are weather patterns, market prices, technological developments, etc. Internal factors relate to local soil characteristics, composition of the family and farmers’ ingenuity. Farmers can decide to opt for mixed enterprises when they want to save resources by interchanging them on the farm - because these permit wider crop rotations and thus reduce dependence on chemicals, because they consider mixed systems closer to nature, or because they allow diversification for better risk management. There is wide variation in mixed systems. Even pastoralists practice a form of mixed farming since their livelihood depends on the management of different feed resources and animal species. Mixed farms are systems that consist of different parts, which together should act as a whole. They thus need to be studied in their entirety and not as separate parts in order to understand the system and the factors that drive farmers and influence their decisions. It may be the most important principle to achieve increased production in mixed systems, together with the awareness that crops and animals have multiple functions.

The domestic electric food juicer/mixer/grinder has become an integral fixture in the typical modern kitchen. Generally functional as liquidizers, grinders and juicers, this paraphernalia comes in handy for grinding/pulverizing/powdering dry foodstuffs either raw or roasted (cereals, grains, masalas, coffee seeds, etc.), for mixing liquids and for converting food— with or without the presence of water (or vegetable oils)—into forms of slurry or pulps. It is also used for extracting juice from fruits or vegetables.

3. Gamet divider works on the principle based on_____.
4. _____ method is suitable for seeds requiring working samples upto 10grams and seeds not chaffy and do not bounce and roll.

1. MIXING AND DIVIDING

The main objective of mixing and dividing of seeds is to obtain the representative homogenous seed sample for analysis by reducing the submitted sample to the desired size of working sample.

2. TYPES OF MECHANICAL DIVIDERS

2.1. Boerner divider

The principle involved in mixing and dividing in gravitational force. It consists of a hopper, a cone and series of baffles directing the seeds into 2 spouts. The baffles are of equal size and equally spaced and every alternate one leading to one spout. They are arranged in circle and are directed inward. A valve at the base of the hopper retains the seeds in the hopper. When the valve is opened, the seeds fall by gravity over the cone where it is equally distributed and approximately equal quantity of seeds will be collected in each spout. A disadvantage of this divider is that it is difficult to check for cleanliness (Fig. 1).

1. Introduction

Mixing is a fundamental and widely practiced operation in many fields, such as chemical, pharmaceutical, and food processing industries. The mixture’s primary aim is to increase the homogeneity of the material in bulk (Uhl and Gray, 1986; Patterson et al., 2004). Mixing means the random distribution of two or more ingredients throughout a system, which differs from the term’ agitation,’ which is defined as establishing a particular flow pattern with the liquid, especially in a circulatory motion within a container. Mixing is a necessary step in the context of food processing operations. 

M-Agriculture

Mobile phones have changed the scenario of telecommunication. It is a source of communication for fast dissemination of information. Today, mobile usage has enabled farming communities to access agricultural and other business information without travelling long distances or reducing costs, time and money. Keeping in view the lower ratio of the farmer to the extension worker (1000: 1) and the inability of the extension workers to guide the farmers as per their information needs, the new concept of m-Agriculture (m-Krishi) has emerged at the beginning of twenty-first century all over the world including India.

Introduction In modern agriculture, soft resources like knowledge and skills are sometimes even more crucial than hard resources like inputs. In the 21st century, agriculture has to overcome a number of obstacles, including feeding an expanding population while a declining rural labour force, producing more feedstocks for a huge bioenergy market, supporting the overall development of many developing countries heavily dependent on agriculture, adopting more efficient and sustainable production techniques, and adapting to climate change (Colle, 2011). In order to make efficient and effective agricultural decisions, farmers are increasingly adopting information (Cash, 2001). Compared to the current availability of roughly 0.1 million personnel, the required number of extension agent who worked in field level is anticipated in between 1.3 to 1.5 million.

Introduction

Information technology is rapidly changing the use of Geographic Information Systems (GISs) from the classic desktop applications into the business service market. With the ubiquitous computing, the settings change dramatically and the classic GIS market will change drastically in the coming few years.

Till mid 90’s, the architecture of GIS focused on a standalone (static) environment. This architecture has been changed to move GIS applications from workstations into mobile GIS applications.

Mobile map applications is not a conventional GIS modified to operate on mobile devices, but a system build using a fundamentally new paradigm(Maguire,2001).

In this paper, we will discuss the integration of XML (eXtensible Markup Language) and J2ME (Java 2 Micro Edition) to build a mobile map application running on 2.5G and 3G mobile devices such as Nokia series 60.

Abstract

The chapter examines the relationship between the agricultural value chain and mobile apps. Using email survey data from mobile app developers, supplemented with basic desk research, the chapter reviews and analyzes 55 mobile apps based on their location within the value chain, the format of content delivery, the types of device used, the stage of deployment as of  2012, the type of business model used, and the geographic focus of the app. The analysis generally reveals an even distribution of apps within the three main components of the agricultural value chain but when it comes to the sub-categories within the agricultural value chain, skewed distribution was observed. Feature phones remain the dominant device for delivering agricultural information to users, however, increasing number of smartphone-specific applications gaining market. Most of the devices use text format for content delivery with voice, image and video as supplements.

Abstract

In Cyprus the National Agricultural Research System is mainly under the authority of the Ministry of Agriculture, Natural Resources and Environment (MANRE). One of its departments, namely the Agricultural Research Institute (ARI), is the only recognized public institution engaged exclusively in applied agricultural research, covering the wider domain of crop and animal production. Another department of the MANRE, the Department of Agriculture (DA) has as its main mission the development of the agricultural and livestock sector through the education and guidance of the farmers, the planning and the implementation of development programmes. 

1. Introduction

One of the most recent running questions of agricultural extension is the potential of rural areas to benefit from mobile communication. Actually, today the increase of the use of mobile phones (MP) is even more rapid in both urban and rural world.

Abstract

Agriculture continues to be the most important sector of the Indian economy and agriculture is a  more or less a compulsion for livelihood of millions of farmers. Land and water resources have almost reached their limits, price of commodities are fluctuating almost every day, profits are negligible for most of the marginal and small farmers and most of all getting information is cumbersome. In present day agriculture, soft resources like knowledge and skills are as important as hard resources like inputs, and sometimes more important. But estimates indicate that 60 per cent of farmers do not access any source of information for advanced agricultural technologies resulting in huge adoption gap. The requirement of field level extension personnel is estimated to be about 1.3 -1.5 million against the present availability of about 0.1 million personnel. The mobile phone comes into the picture here.

1. Introduction

A cooperative agricultural extension service has been implemented in Japan by both national and prefectural governments to support small-scale farmers who emerged as a result of land reform after the Second World War (Yamada, 2008).  In recent years, however, the scope and level of agricultural extension advisors’ activities have become more sophisticated and diversified because of technological progress and a wider range of activities, from production and selling to promoting relevant political measures.  On the other hand, the number of agricultural extension advisors has been decreasing for several years because of a cut in government expenditure for the cooperative extension service.  For this reason, information and communication technology (ICT) is needed to promote advanced and efficient extension activities (Yamada, 2010).

Abstract
 
Nigeria has a very large domestic market, but consumers, farmers, processors and other agribusiness investors are often faced with challenges getting timely and relevant information. However, it has been found out that in Nigeria many people preferred receiving information over a mobile phone than a computer. The problems farmers encounter in exchanging information and that more than half of Nigeria’s population are mobile phone subscribers of which majority of them are farmers necessitate overview of Information and Communication Technologies (ICTs)  and agricultural development in Nigeria. Literatures were consulted, secondary data, and personal observations were tools used to compile the chapter contribution.

1. Introduction

For the last years, Peru’s GDP has been continuously growing, and in 2010 the agricultural sector has played a significant role in this process. According to the National System on Agricultural Innovation, the sector has an important contribution in economic and social aspects.Regarding the former, national agrarian production represents 8% of global GDP.
 
Statistics of the Ministry of Agriculture of Peru show that the agricultural sector includes 31% (3 million people approximately) of the country’s Economically Active Population (EAP), and 65% of the EAP in rural areas. The latest agrarian census indicates that almost 5.5 million hectares are used for agricultural activities, which accounts for 15% of the total surface.

Abstract

The contribution of agriculture to the Tanzania’s economic growth has not been fully realized due to the sector’s’poor performance. This is attributed to a combination of constraints, which are often aggravated by lack of access to timely, relevant and reliable agricultural information. The traditional approach of delivering agricultural information through extension services has been criticized widely as there are weak information flows amongst agricultural actors.

Abstract

With the evolution of Information and Communication Technology (ICT) in Agriculture as the major employer of Ugandans population with over 82% of the population, agricultural information is a key component in improving small-

A mobile phone often referred to as a cellular phone or cell phone is an electronic telecommunication device that can make and receive telephone calls through radio wave or satellite transmission whilst moving around a wide geographic area. Most mobile phones provide voice communications, Short Message Service (SMS), Multimedia Message Service (MMS), short range wireless communication (Infrared, Bluetooth), business applications, gaming, photography and internet services such as web browsing and e-mail. Mobile communication technology has become the world’s most common way of transmitting voice, data and services, and no other technology has ever spread so fast. The mobile phone is especially important for India because it is growing here faster.

ABSTRACT

In 21^st century, the world has turned into a global village. This herculean task has been made possible with the advent of ICT tools. When we think of ICT, the most omnipresent tool that comes in our mind is mobile phones. With the increasing rate of mobile phone penetration in the urban as well as in rural areas, it is now possible to connect the farmers leaving in the far-flung areas with the institutes, who are working for the betterment of farming community. Today, mobile phones play a significant role in everybody’s life, besides being an efficient way to stay connected with the family; it also paves a way to bridge the gap between the availability and delivery of agricultural inputs and agricultural infrastructure. Mobile phones provide basic connectivity, mobility and security to owners, it works using the radio spectrum, so no need to rely on physical infrastructure, requires basic literacy only, also its services are available in local language; short message service (SMS), multi-media service (MMS) and voice communication are the added benefits. It allows transfer of data which can be used in the context of applications for the purpose of health, education, commerce and governance. Mobile phones are increasingly affordable due to factors like increased private sector competition and innovative payment methods. Due to high access, its reach, good adoption and real-time interaction mobile phones offer efficient solutions to governments’ communication challenges. Mobile phones helps the farmers in agriculture decision making, as they provide information related to crops, weather forecasting, seeds, fertilizers, bio-pesticides, soil fertility, pest and disease diagnosis, demand and supply of agricultural products, different schemes and technologies. Mobile based initiatives like SMS services related to weather forecast, disease forecast, and market information are issued to farmers by different organizations like IFFCO Kissan Sanchar Limited (IKSL) and Reuters Market Light (RML). Farmers can raise queries related to agriculture and allied sectors using their mobile phone to a farmer call centre which has been operating in every state of India. There are many such initiatives, which are working to provide valuable services, and also it provides opportunities to further explore the potentialities of mobile phones as a tool for transforming the farming scenario of India.

Introduction

The past decade has witnessed a revolution in the use of ICT in Developing countries. Many people and offices as well as rural farmers own ICT facilities such as personal computers and mobile phones. The largest increases in the use of ICT has been in mobile telephony where subscriptions in developing countries increased from about 30 percent of the world total in 2000 to more than 50 percent in 2004 and to almost 70 percent in 2007 (Cieslikowsk, Halewood, Kimura, & Zhen-Wei Qiang, 2009). While internet use has not increased as rapidly as mobile communication, it increased tenfold in developing countries in the same period (Cieslikowsk et al., 2009). Other ICT facilities such as telecast, radio FM and information centres have also increased in number remarkably during the same period. A study by Farrell & Isaacs, (2009) on ICT in 53 African countries revealed the wide use of ICT in the region with countries such as Algeria, Egypt, South Africa and Botswana leading in ICT use. In East Africa, Rwanda is probably the most advanced country in terms of ICT use with 65% of its population being covered by mobile telephony. The country has also a high level of internet use and access to television and radio broadcasts. In Kenya, Uganda and Burundi the use of ICT is also well advanced, especially for mobile phone subscribers, TV and radio listeners (Farrell & Isaacs, (2009). This high use of ICT is likely to stimulate economic development in developing countries, including the agricultural sector where a high proportion of the African population derives their livelihoods. Before 1990, ICT use in Tanzania was mainly limited to radio and landline telephones. New ICT started in the mid-1990s, and by 2001 it was estimated that Tanzania’s ICT industry had generated USD 300-350 million per year. There are now a number of ICT development initiatives in the country funded by the government, donor countries and the private sector. Such initiatives range from telecentres and mobile phones in rural Tanzania to e-Government initiatives being implemented in the major cities and towns of Tanzania.

7.1 Introduction

The evolution of the digital landscape has been nothing short of revolutionary, shaping the way we live, work, and interact with one another. Since the inception of the ARPANET military experiment in 1968, which laid the groundwork for the internet as we know it today, the world's digitization has been accelerating at an unprecedented pace. What started as a military endeavor has evolved into a global network connecting billions of people across geographical boundaries, giving rise to virtual communities, and fundamentally transforming the way information is accessed and disseminated. As we navigate through this digital age, characterized by rapid technological advancements and an ever expanding digital ecosystem, the role of individuals in this landscape has evolved significantly.

Today, in many countries mobile phones are being used by farmers, not only as a person voice communication medium but also to provide access to  information through sending message service (SMS), multimedia messages service (MMS) and access to the internet. Across the developing world, there are programmes that give farmers access to research and best practices, weather information and market prices via SMS, Interactive Voice Response (IVR) or call centers.

Introduction

Krishi Vigyan Kendras (KVKs) have marked their presence across India by executing various scientific as well as institutional reforms for the agrarian mass of our country. Right from its beginning in 1970s, farmers were actively trained for adopting different innovative tools and methods and were also provided with proper assistance in implementing them. The farmers were adapted to technical know-how of an introduced technology and produced significant results in the real f ield conditions.

KVKs provided proper training programmes on need-based curriculum in order to cater to the local and regional needs. This has also led to need assessment of various training needs and efficacies to make improvement in policies and future interventions. KVK can be instrumental in nurturing the process of gender empowerment by inviting and involving the farm women in the process of technological adaptation, adoption and socialization. There are methodological innovations as to how we can involve the farm women by employing and applying gender-sensitive KVK technologies as suitable for their job environment and climate. Especially in areas of value addition, rural crafts, women crafts, f ishery, horticulture and micro-finance, their roles are becoming more prominent and decisive. This is positive achievement in making them free from gender discrimination and impoverishment.

The knowledge score gained by respondents after training was more satisfactory in all aspects (58.33% had medium and 48.67% had high level of knowledge). The socio-economic factors of the participants viz. Education level played a significant positive role on the knowledge gain of the participants. (Upamanya et.al., 2020) Most of the farmers, i.e., 66.67 per cent with theoretical knowledge suggested that more field visits can be arranged, 63.33 per cent of the respondents suggested the training should be conducted in their own villages because the farm women cannot able to come to KVK by leaving their children and their regular household work and around sixty per cent (60.83 per cent) of the respondents suggested that organizing continuous and frequent training programmes for effective participation and retention of knowledge. (Chakkaravarthy and Balakrishnan, 2020)

Horticulture includes fruits, vegetables, floriculture, spices, tubers, plantation crops, medicinal and aromatic plants and mushrooms. The sector has established its importance in improving land use, promoting crop diversification, generating employment and above all providing nutritional security to the people. Even though India is the second largest producer of horticulture produces in the world, our per capita consumption of fruits and vegetables are very low.

Mode of Action of Fungicides

Most fungicides function outside of the host, which is referred to as “protection.” A fungicide that acts outside of the host is referred to as a “protectant fungicide.” This category includes the majority of older fungicides applied on leaves and fruit. “Therapy” refers to chemical action within the host. Fungicides, for example, are locally systemic and enter the plant at the point of deposition. Several triazole fungicides have several days of therapeutic action against wheat leaf rust and also inhibit the development of viable spores (spores that can grow).

The majority of protectant fungicides are relatively stable on their own. They are generally insoluble in water and resist removal or chemical alteration by water, but they must be toxic to fungus.

The mode of action is the overall manner in which a herbicide affects a plant at the tissue or cellular level. The mode of action is the way in which the herbicide controls susceptible plants. It usually describes the biological process or enzyme in the plant that the herbicide interrupts, affecting normal plant growth and development. Herbicide may act on the life process of plant and dislodge the normal functioning of plants resulting in the death of plants. Herbicides  do damage of plants by inhibiting the biological process of plant as follows:

Mode of Action

The term mode of action refers to the sequence of events from absorption into plants to plant death. The mode of action of the herbicide influences how the herbicide is applied. For example, contact herbicides that disrupt cell membranes, such as acifluorfen (Blazer) or paraquat (Gramoxone Extra), need to be applied post emergence to leaf tissue in order to be effective. Seedling growth inhibitors, such as trifluralin (Treflan) and alachlor (Lasso), need to be applied to the soil to effectively control newly germinated seedlings.

To be effective, herbicides must 1) adequately contact plants; 2) be absorbed by plants; 3) move within the plants to the site of action, without being deactivated; and 4) reach toxic levels at the site of action. The application method used, whether pre-plant incorporated, pre-emergence, or postemergence, determines whether the herbicide will contact germinating seedlings, roots, shoots, or leaves of plants.

Mode of Action of Herbicides

Herbicides perform a vital role in the management of weeds. As the name indicates, herbicides are chemicals that kill or control vegetation. Although the ultimate effect of most herbicides is the same (usually death of weed), the way they control weeds is vastly different. Physiologists use the term mode of action to describe the way the herbicides affect weeds. It includes the entire sequence of events that occur from the time the weed absorbs the herbicide to the final plant response (usually death). The term mode of action is the broad term under which all aspects of herbicidal action including the mechanism of action is included, while the mechanism of action refers to only the biochemical and biophysical responses of plants that appeared to be associated with herbicidal action.

Thus, mode of action includes absorption, translocation to an active site, inhibition of a specific biochemical reaction, degradation or breakdown of the herbicide in the plant and soil and the effect of the herbicide on plant growth and physiology.

Although two herbicides may differ chemically, they may still possess the same mode of action example trifluralin (a dinitroaniles herbicide) and propanamide (an amide herbicide) are inhibitors of microtubule/spindle apparatus. Each herbicide family (class or group) has a primary site of action which may be different in its action from others example sulfonylureas herbicides are ALS or AHAS inhibitors while glyphosate and sulfosate are ESPS inhibitors. Some may have more than one site of action, but the mostinhibitory of these will be affected first. The other site(s) may be considered secondary. Fluometuron, a urea group herbicides act by inhibiting photosynthesis at photosystem II and carotenoid biosynthesis.

6.1 Introduction

The process by which living beings give rise to the progeny of similar kind is called reproduction. Reproduction allows both multiplication and maintenance of a genotype/line/cultivar/species. So, the process of reproduction is also called propagation, and the plant part used for this purpose is called propagule. The way progeny originate is known as mode of reproduction (also called breeding system or reproductive system). The mode of reproduction of a crop determines its genetic composition which, in turn, is the deciding factor to develop suitable breeding methods. Knowledge of mode of reproduction is also essential for its artificial manipulation to breed improved types. The methods to be adopted for multiplication and maintenance of improved cultivars are also governed by the mode of reproduction. Especially in undertaking breeding investigations with new plants the nature of reproduction must be known before efficient breeding plans can be developed. The mode of reproduction has been well established for most of our important crop species.

6.2 Mode of Reproduction

Mode reproduction in crop plants may be sexual or asexual. In sexual reproduction (also called amphimixis), specialized reproductive cells called gametes are formed by the process of gametogenesis. Fusion of the male and female gametes leads to the development of an embryo and eventually the seed. In asexual reproduction, fusion of the male and female gametes does not occur, and new plants arise from unfertilized gametes (but not from zygote), or from specialized vegetative organs such as rhizome, tuber, bulb, corm, runner, sucker, stolon, bulbil etc., or by various artificial means of propagation such as rooting of stem and root cuttings, layering, grafting, gootee, etc., or tissue culturing.

The different modes of reproduction applied in vegetable crops are

Asexual

In this case the vegetative parts of the plants viz. rhizomes, corms, tubers, bulbs etc whole or part there off are utilized to produce new individuals. The typical examples are potato, sweetpotato, parwal, artichoke, colocasia, zinger, turmeric elephant foot yam, etc. There are some vegetative crops which can be reproduced through bcth vegetative part as well as seed e.g. asparagus.

Introduction

Agriculture is an important sector for countries like India, who have majority of its population, directly or indirectly depend upon agriculture. The sector which feeds the majority of population of any country needs special attention for its all round development. Marketing is such a crucial aspect related to agriculture that is probably not developed in any of such countries which largely depends upon agriculture. Underdeveloped and lack of resources are the main reasons behind the underdeveloped nature of agricultural marketing. In simple terms, agricultural marketing means the buying and selling of agricultural produce. The Indian council of Agricultural Research defined involvement of three important functions, namely assembling, preparation for consumption and distribution.

Introduction

Jackfruit (Artocarpus heterophyllus) is the largest edible fruit in the world. It is a seasonal fruit found in almost all the humid tropical regions of the world. It is very popular all over India and is believed to be of Indian origin. Flesh of jackfruit is starchy and fibrous and is a source of dietary fiber. Varieties are distinguished according to characteristics of the fruit’s flesh. In Kerala, two varieties of jackfruit predominate: varikka and koozha. Varikka has a slightly hard inner flesh when ripe, while the inner flesh of ripe koozha fruit is very soft and almost dissolving. Strong aroma of the fruit accounts popularity of its processed products. Each year, approximately 30-50% of the total harvested fruit is spoiled because of lack of post-harvest processing in India

Jackfruit has more protein, calcium, thiamine, riboflavin and carotene than banana. Edible bulbs of ripe jackfruit are consumed for their fine taste and pleasant aroma. The fibre content helps to protect the colon mucous membrane by decreasing exposure time as well as binding to cancer-causing chemicals in the colon. Fresh fruit has small amounts of carotenoid and flavonoid pigments such as ß carotene, xanthin, lutein and cryptoxanthin-ß. Together, these compounds play vital roles in antioxidant and vision functions.
