The quantity of space available for product storage is referred to as warehouse capacity. Understanding the distinction between theoretical working capacity and storage capacity can be aided by warehouse capacity. In warehouses and other storage facilities, space is perhaps the most valuable resource for online retailers. By making the most of their warehouse space, businesses can significantly increase the quantity of goods they can store there. Having more things in storage at once can save them money on transportation and other expenses.
It also makes it easier for the warehouse KPI staff to access the products, which helps them process orders faster and deliver the goods to customers sooner. Because space can be limited in a warehouse setting, warehouse managers and business owners should take the time to assess how much space they have and how well they’re using it.
STEP TO CALCULATE WAREHOUSE STORAGE CAPACITY
Understanding your warehouse’s current capacity is the first step in
determining how to increase it. This brief guide will show you how to calculate a
warehouse’s capacity in feet:
• Calculate the total square footage of your warehouse complex. Let’s assume that it is 10,000 square feet in this case.
• Determine the total amount of space devoted to non-storage purposes, such as offices, loading areas, restrooms, and break rooms. Assume for the moment that this is equivalent to 2,000 square feet.
• Subtract the total square feet of non-storage space from the total square feet of your warehouse to determine the usable space. The following is the equation:
USABLE SPACE-TOTAL SQUARE FEET – NON-STORAGE SPACE SQUARE FEET
Determine the total usable storage space by identifying the maximum stack height or clear height. This should account for the lowest-hanging overhead

Asbestos mat – Digest asbestos with dilute hydrochloric acid(1:3) for 2-3 days, wash free from acid and digest with 10% sodium hydroxide for few days, wash free from alkali. Digest with dilute Nitric acid(1:3) for several hours and wash. Shake with water into fine pulp and digest with 0.1N potassium permanganate solution that has been acidified with dilute sulphuric acid (1:3), for 1 hour and wash. Use this pulp for layering 6mm film on Gooch crucible.

Dilute hydrochloric acid (1:4), Ammonium hydroxide solution (1:1), Saturated ammonium oxalate solution, Diluted sulphuric acid (1:4)

Materials Required

Sample, hot air oven, weighing balance, crucibles, muffle furnace, lead pencil / marker etc.

Procedure

    1.    After following the procedure for the determination of moisture (in silica crucibles as given in previous chapter) the same sample can be used for the determination of ash. 
    2.    Heat the dried sample in the silica crucibles over a heater/hot plate/burner to burn the carbon.
    3.    When it becomes completely black and no more smoke comes out of the sample, shift them to muffle furnace.
    4.    After heating the samples in muffle furnace, all the marks of pen / pencil/ marker are lost, so one would not be able to identify the samples and error of weights may occur. Therefore, it is advised to place the samples in the furnace in one or two rows and draw the diagram on a piece of paper for identification purpose.

Fruit, vegetable or product sample, hot air oven, weighing balance, crucibles, petri plates, lead pencil / marker etc.

Procedure

    1.    Take crucibles  or petri plates and record the tare weight of crucibles / petri plates (C) and mark them
    2.    Cut the sample into small and thin pieces (if solid)
    3.    Put the sample into the crucibles / petri plates in three replications
    4.    Record the weight of crucibles + sample (C + S)
    5.    Put in hot air oven for drying at 70 + 2ºC.
    6.    Record the loss in weight after every 1-2 hrs till it becomes constant
    7.    Calculate the moisture and total solids. 

Introduction Diet and dietary component are proved to be the first line of intervention in prevention and treatment of non-communicable diseases by many studies (R. Vrolix and R.P. Mensink, 2010). Hence the interest has grown in development of functional food product in recent years which provides not only basic nutrients but also has health promoting and diseases preventing properties (Rozek et al., 2010). The Functional Food Center (FFC) defines “functional food” as natural or processed foods that contain known or unknown biologically-active compounds; the foods, as defined, effective, and non-toxic amounts, provide a clinically proven and documented health benefit for the prevention, management, or treatment of chronic disease (Martirosyan et al., 2015). Fiber is classified into two separate groups i.e. soluble which forms gel like substance when comes in contact with water and insoluble is a solid form that does not break down when exposed to water (web 4). Soluble fibers increase total transit time by delaying gastric emptying and also slow glucose absorption, which includes pectins, β-glucans, galactomannan gums, mucilages, and some hemicelluloses (J.H.Cummings and A.M.Stephen 2007). The American Society for Nutrition stated that cereal fibers are modestly associated with a reduced risk of type II diabetes, obesity, and cardiovascular disease (Cho Qi, Fahey Jr & Klurfield, 2013).

    8.    After going through Annexure II you may conclude that the two samples differed significantly from each other as 16 out of 20 evaluators found the odd sample correct. But, the preference was not significant as it should have been at least 13 out of 16 judges indicating same preference so as to make it significant. So, it may be concluded that the two samples differ significantly but both are acceptable.

    3.    Put a drop of material on to the glass surface of refrectrometer’s prism, cover gently with the lid and observe the TSS against light.
    4.    Measure the temperature of the liquid which is being evaluated and apply temperature corrections (Annexure III).
    5.    Record the corrected value as the TSS of the sample.

Developing a nutraceutical or functional food is becoming mandatory as looking at the current nutritional status of the population over the world. Nutraceutical foods are proven to cause several health benefits to people. Hence the basic aim behind developing the nutraceutical chocolate bar was to fulfill the nutritional demands and provide some additional benefits to people. The product mainly contains two key ingredients that are, Drumstick (Morings oleifera) which has the most qualities to call a Superfood” and Quinoa (Chenopodium quinoa) which is referred to as “Mother of all grains”.

Introduction Sea food processing is one of the major contributors in food processing sector. The purpose of seafood processing is to prevent the wastage and prolong the shelf life of highly perishable commodity. It also increases the economy of the country through exports (Gopal et al., 2014). India produce 9.6 million MT of sea food during the every year and is one of the largest fish producers in the world. 23% of marine products are processed currently in India (Sathianandan, 2017). Pasteurized crab meat is one type of processed marine commodity exported from India. Globally, the pasteurized blue crab and swimming crabs are the major contributors to the economic wellbeing of the seafood industry. In India, pasteurized crab meat industries are significantly contributing to the export markets. Among the crab export, 70-80% is exported as pasteurized crab meat (Jebadurai17, 2014).

Materials required
Material : Wheat Flour (1000g), Shortening (350 g), Fine Sugar (400 g), Sodium bicarbonate (10 g), Dextrose solution (100 ml) i.e 25 g Dextrose hydrate in 500 ml water, Distilled water (50 ml), salt (8 g).
Equipments: Mixer, rolling pin, Tray, cookies cutter, baking oven etc.
Principle: Cookies are made from soft wheat are having high sugar and fat content. They contain relatively low moisture content and have fairy high shelf life. Biscuits are similar name used in Europe and UK. Cookies are chemically leavened. Sugar and shortening are creamed to form dough with flour and leavening agents. When cookies dough enters the oven, the fat starts melting and sugar is dissolved which allow the cookies to spread as a function of gravity. The leavening agents expand it in all direction and structure is stabilized with high temperature prevailing in the oven.

Introduction

Meaning of Entrepreneur

The term “entrepreneur” is derived from the French verb entreprendre, which means “to undertake.” Historically, its meaning has evolved. In the early 16th century, it referred to individuals involved in engineering tasks like construction. By the 18th century, the term came to describe those engaged in economic activities. Over time, the concept of an entrepreneur shifted from someone participating in military ventures to someone actively involved in business and economic pursuits. Today, an entrepreneur is defined as an individual who innovates, organizes resources, and takes on risks to create new ventures or products with the goal of generating profits.

Richard Cantillon was the first who proposed the term “entrepreneur is an agent who buys factors of production at certain prices in order to combine them into a product with a view to selling it at uncertain prices in future.”

Principle
Jam: Jam is a product made by boiling the fruit pulp with a sufficient quantity of sugar to reasonable consistency, firm enough to hold fruit tissues in position. Apple, pear, sapota, apricot, carrot etc. are used for preparation of fruit jam. Jam contains 0.5-0.6 % acid and invert sugar should not be more than 40 %.
Total soluble solids (TSS)
The TSS value is defined as the amount of sugar and soluble minerals present in fruits and vegetables. A refractometer is based on the principle of total refraction. This is done by placing a few drops of distilled water on the prism in the specimen chamber of the back the cover. The distilled water reading should be zero. If it is not so, it should be set to zero with the scale correction knob. The specimen chamber is now cleaned with muslin cloth or tissue paper. For determining the TSS, a drop of sample (jam, juice and syrup, etc.) is placed on the prism and the percentage of dry substance in it read directly on scale in refractometer.

Principle
Jelly: Jelly is a semi-solid product prepared by boiling a clear, strained solution of pectin containing fruit extract, free from pulp, after the addition of sugar and acid. A perfect jelly should be transparent, well set, but not too stiff, and should have the original flavour of the fruit. It should be of attractive colour and keep its shape when removed from the mould. Pectin (0.5-1.0%), acid (0.5-0.75%), sugar (65%), and water are the four essential ingredients. Pectin test and determination of end-point of jelly formation are very important for the quality of the jelly. Some recipes for jelly making are given below:

Principle
Nectar: The term ‘fruit nectar’ is used to designate pulpy fruit juice blended with sugar syrup and citric acid to produce a ready-to-drink beverage. In this fruit beverage contains at least 20% juice/pulp and 15% total soluble solid and also 0.3% acid. It is not diluted before serving. Many fruit juices are either too acidic or strongly flavoured; these cannot be pleasant without dilution of blending or both. These strong, tart juices are delicious after dilution with thin syrup or blend juice e.g. apricot, guava and plum juice. Out of the tropical fruits, nectars made from banana, guava, mango and papaya are quite popular. The product is sealed in container or glass bottles and processed by heat to prevent spoilage. The fruit ingredients may be puree, pulp, juice or concentrated equivalent to 40 percent of the finished products. Apples, cherries and pineapples are used in combination with others fruits. The sweeteners are sugar, invert sugar syrup, dried corn syrup, glucose syrup and the optional ingredients are lemon juice, citric, malic and fumaric acids as acidifier and ascorbic acid as antioxidants (150 ppm) can be used.
