Distillation of rose oil and rose water:

For distillation of rose oil and rose water initially the fresh rose flower are hydro distilled. The oil and water are collected together. The oil which floats upon the water is separated by decantation get oil directly, while the water is re-distillated. The oil obtained from re-distillation is called recovered oil or water oil. The direct oil and water oil are then combined to make the commercial rose oil.

The water obtained from the second re-distillation step is the commercial rose water

Curing- Curing is a process in which produce is subjected to undergow through a special treatment to get the quality product.

Structure of turmeric process

Boiling

• Boiling figures in water in copper vessels/galvanized iron/earthen vessels
• If water is acidic then add NaCO₃
• Stopped boiling when froth starts coming out and white fume appears
• Then dried in the sun for 10-15 days till they become hard and brittle

Material balance data

Guava pulp : 5.00 kg

Amount of sugar added : 4.50 kg

Amount of glucose added : 500 gm

Amount of SMP added : 700 gm

Squash: It is a type of fruit beverage containing at list 25% fruit juice or pulp and 40-50% TSS commercially. It’s also containing about 1% citric acid and 350ppm sulphurdioxide or 600ppm sodium benzoate. Generally it is diluted before serving. Mango, orange, pineapple, lemon, lime, guava, litchi etc are commercially used for squash making using KMS as preservative. The coloured fruit like jamun, passion fruit, peach, phalasa, plum, mulberry, strawberry and grapefruits are also used for making squash but due to bleaching effect KMS is not used as preservative. In such types of fruits sodium benzoate used as preservative.

Beverages:-The fruit beverages are easily digestible, highly refreshing, thirst quenching, appetizing, nutritionally for superior than many other synthetic drink. There are two types of fruit beverages i.e. unfermented beverages and fermented beverages. Natural juice, RTS (Ready to Serve), nector, cordial, squash, crush syrup, fruit juice concentrate and fruit juice powder are the main unfermented beverages. The fermented beverages are wine, champaigne, port, sherry, tokay, muscut, neera, cidar, orange wine, berry wine and fenny are the important.

Preserve:- Amature fruits/vegetable or its pieces impregnated with heavy sugar syrup till it become tender and transparent is known as preserve. The fruits like aonla, bael, apple, pear, mango, cherry, karonda, pineapple, papaya are commonly used.

Candied fruit:-A fruits/vegetable impregnated with cane sugar syrup and subsequently drained free of syrup and dried is known as candy. The most suitable fruits are aonla, apple, pear, cherry, karonda, pineapple, papaya are commonly used. In candy the total sugar contains of the impregnated fruits is kept about 75% to prevent fermentation.

Marmalade: Marmalade is a fruit jelly in which peels of the fruits is in suspended forms. This product is generally prepared from citrus fruit like orange and lemon. The citrus marmalade can be classified into jelly marmalade and jam marmalade. 1 kg pectin extract required 750g sugar and 62g shredded peel.

Jelly:-Jelly is a semi solid product prepared by boiling a solution of pectin containing fruit extract free from pulp after the addition of sugar and acid. A perfect jelly should be transparent, well set, should have original flavour of the fruits, attractive colour and it should be free from dullness. Jelly is mainly prepared by guava, sour apple, wood apple, loquat and papaya. Apricot, pineapple, strawberry etc of low pectin containing fruits can also utilize after addition of pectin powder because these fruits have low pectin contain.

Jam:-Jam is a product made by boiling fruit pulp with sufficient sugar to a reasonably thick consistency. Jam is mainly prepared by apple, pear, sapota, apricot, peach, papaya, karonda etc. It can be prepared from one kind of fruits or from two or more kind of fruits. In general jam contain 0.5-0.6% acid and invert sugar should not be more than 40%.

Canning: Cannings the process by which sealing of the food product and sterilizing them by heat for long storage is known as canning.

The term canning was first invented by N. Appert (1804) in France. In honour of the inventor canning is also known as appertization (Appart is known as the father of canning). The main principle of canning is destruction of spoilage organism by means of heat. The procedure of the canning should be as follows.

Preparation of the material: Common minute material for analysis in Waring blender for 1 to 2 minutes. Do not over heat. Pass it through No.60 sieve and put is in airtight container.

Procedure: Take 2 to 3 g sample in duplicate in pre-dried and pre-weighed 7 cm diameter aluminium dishes. Remove the dish cover and put them in vacuum oven and dry for 6 hours at 88°C and 26-22 inch vacuum. During this process, admit to oven a slow current of air (2 bubbles per second) dried by passing H₂SO₄ replace the cover, cool it in desiccators and weigh again.

Procedure: Standardize the pH meter with a buffer solution of pH. Take the sample solution in a 100 ml beaker. Put the electrodes in the solution and read on pH meter. After each observation, wipe the electrodes with a piece of cotton soaked in distilled water and rinse the electrodes with water with the help of a wash bottle and dry with filter paper.

Principle: Addition of calcium chloride results in the precipitation of pectin as calcium pectate from an acid solution. Calcium pectate is washed with water to make free from chloride and is dried and weighed.

Principle: Sample extract in oxalic acid is titrated against standard sodium 2, 6 dichlorophenolindophenol dye to a faint pink colour which persists for 5-10 seconds.

(Indophenols Method)

Fructose, a keto-hexose (called as fruit sugar), is usually accompanied by sucrose in fruits and estimated by the methods of Ashwell (1957).

Materials

Resourcinol reagent: Dissolve 1g resorcinol and 0.25 g thiourea in 10 ml glacial acetic acid. This is stable in the dark.

Dilute HCl: Mix five part of conc. HCl with one part of distilled water.

Standard fructose solution: Dissolve 50mg of fructose in 50 ml water. Dilute 5 ml of this stock soln. to 50 ml for a working standard.

Principle: The copper in the Fehling solution is reduced to red, insoluble cuprous oxide in the presence of invert sugars like glucose and fructose. The quantity of sugars solution liquids for complete neutralization of a known quantity of Fehling mixture is determined by titration using methylene blue as the indicator.

(Lane and Eynon Method)

Purpose: The organic acids present in fruits and vegetables influence the flavour, colour, keeping quality and maturity. The maturity standards are determined by the acid and sugar ratio. The total acidity (citric acid) is determined by titrating the juice against standard alkali solution.

Equipments and chemicals: 10 ml., pipette, 25ml. Burette, small glass funnel, dropper, juice extractor, distilled water, 100ml. volumetric flask, burette stand, beaker, N/10 sodium hydroxide, filter paper, phenolphthalein indicator (one gram of phenolphthalein in 100ml. of 95% ethyl alcohol)

Principle: To determine water in soluble solids, a known quantity of sample is boiled in water and the insoluble material is collected on a weighed filter paper. The insoluble mass is then washed with hot water and dried in oven.

Purpose: The ash content of plants represents the deposition of minerals elements in the plant or in its parts. The value of ash content in the plant tissue indicates the health of the plant. Plant ash is also used both in qualitative and quantitative estimation of mineral elements.

Material and Equipments: Crucible, oven, chemical balance and weight box.

Principle: A weighed sample is dried in an oven at 60-70⁰C up to a period of time when weighing made at 2 hour intervals do not differ by more than 2-3 mg.

Purpose: The estimation of total soluble constituents gives the approximate amount of water soluble substance present in the sample. Among the various soluble substances the amount of sugar is 80-85 percent. The TSS value is roughly considered to be the amount of sugar and soluble minerals present in fruits and vegetables. The total soluble solid content can be determined by hand refrectometer.

Material and equipments: Hand refrectometer, juice, muslin cloth or tissue paper and glass rod.

Standard solution: Standard solution is defined as a solution whose strength is known. e.g. 1 N solution.

Molar solution: Molar solution can be defined as a solution containing the number of moles of a solute (substance) i.e. molecular weight in gram per litre of the solution. e g. Mol. wt. of NaCl 23+35.5 58.5,

So 58.5 g NaCl per 941.5 ml of water= 1 M NaCI solution. Molarity is generally designated by M.

Molal solution: Number of moles of a substance/solute per litre of solvent makes a molal solution. Mobility is generally designated by m.

Shrubbery-An area of cultivated shrubs in a parkor garden is known asshrubbery or any area in the garden fully solely devoted to the shrub plantation is called shrubbery. These shrubs are maintained in formal way therefore require regular training, pruning and clipping. Maintenance of shrubbery is easy and become less costly if planted properly considering following point (See plate 22).

• Selection of hardy shrubs.
• Shrubs having profuse flowering and beautiful foliage.
• Selection of shrub according to soil.
• Shrub having slow growing habit and required less pruning and management.

Herbaceous border

In this system plant are arranged in irregular group of a kind for harmonious are contrasting colour effect, either all flowering at one time or successfully in such a way that those flowering latter should grow up and screen the all ready flowered. The planting of annuals in the border of a plot is called as herbaceous border. When the border is to be viewed from both side tall plant are planted in center followed by medium and dwarf planting in both side. Herbaceous border may include all the herbaceous plant including herbaceous perennial (Flowering and non flowering) bulbous and annuals (see plate 20 & 21).

Purpose-Planting of foliage and flowering trees, shrubs, climbers, annuals, perennials and lawn in a piece of land by adopting certain principles is termed as garden design. The objective of a garden layout by adopting a design to provide recreation, enjoyment and education to the society. Natural flora, religion, topography of land and climatic had played a major role in the development of garden designs. Basically there are two garden designs. In one the plantation of shrubs, trees, climbers etc. and lawns is done by adopting a geometrical design and maintaining bilateral balance whereas, in the other one the plantation is done by taking in account the topography and terrin of land, containing open lawns and cluster of trees. The former is called formal are artificial garden while the later is called as informal or landscape garden.

Lawn

Lawn is a natural green carpet, and it is important feature of a landscape and a garden without a lawn is not considered complete. Lawn is an area of land closed mowed grasses it is primarily developed for aesthetic and recreational purpose. A lawn is an integral part of a garden and landscape besides aesthetic and recreational purpose and several other purposes. Lawn provides a place for taking rest after tiring of the day, holding parties, social functions, passive and active recreation. Distinguishing characteristic of turf grasses is the ability to with stand close mowing and still providing a functional dense healthy ground cover. Lawn is also called as heart of garden. J.B. Olcoth designed first experiment in lawn grass at Monchester in USA in the 19th century. Festuca and Agrostis species were used to make turf (Lawn) during 1880 in U.K. In the early 19th century lawn become wild spread out side of parks golf course. Now a day in many metro cities of India lawn has become a cultural of the passion of many homes.

Edge plant

Very low growing plants grown only for the purpose of decoration and demarcation and not for screening are known as edging. Live and inert materials used for living of borders flower beds, paths, lawn, shrubbery and herbaceous border are known as edging. Formal edgings are: Bricks, stones, tiles, concrete etc. Informal edging are: Grass verges and crazy paths made up of tiles stones etc.

Important diseases of vegetable crops

1. Damping off: (Phytophthora parasitica, Pythium sp. Rhizoctomia solani):This is a disease of the seedlings at the nursery stage. Due to the attack of this fungus seedlings rot at the ground level and collaps.

Important insect-pests of vegetable crops

1. Aphids: (Myzus persicae)

The aphids damage the crop by sucking the cell sap from the leaves as stems. The affected leaves in severe cases curl-up and rolled. The plant may be stunted, wither and die. There are three different species of aphids. They are greenish or black in colour.

Problem- Calculate the amount of farm yard manure, urea, single super phosphate and murate of potash for one hectare tomato crop which require 100, 60, 60 kg ha N, P, K respectively. 1/3 quantity of nitrogen should be given through farm yard manure and rest through chemical fertilizers

A. Concentrated Organic Manures

Improved production technology is an integral part of hybrid seed production technology, which is a very high venture practice. This is because like several factors (climate, availability of parental lines and technical labour etc), success of hybrid seed production also depends on the success of crop management in the hybrid seed production field

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.

Purpose: This test is conducted to determine the boldness and soundness of the seeds. The weight of a given number of seeds of different varieties or kinds will vary. This variation is due to boldness and soundness of the seeds. The seeds will vary according to the soil fertility, variety and other environmental conditions. Higher the weight of a variety per thousand seeds, better is the variety for cultivation.

Materials and equipments: Scale, balance and seeds.
