Castor meal is also variously called castor meal, castor residue, castor extract & de-oiled castor cake Castor meal - the residue obtained from castor cake by the solvent extraction process - is one of the most versatile natural manures. It is truly organic manure which enhances the fertility of the soil without causing any damage or decay. It is enriched with the three big elements vital and conducive to the proper growth of crops - Nitrogen, Phosphorus and Potassium. It also has traces of nutrients like Manganese, Zinc and Copper, thus making it a balanced fertilizer. Moreover, it helps to neutralize the detrimental effects of chemical fertilizers. Apart from their contribution to Nutrients, they have a number of benefits in agriculture, which none of the synthetic fertilizers or pesticides can offer. They bring in the wonderful molecules that nature has designed to help the plants flourish naturally. They provide slow and steady nourishment, stimulation, protection from soil nematodes and insects; improve yields, and quality of product like taste, flavour, amino acid composition etc. The pressed cake obtained after the expression of castor bean. The solvent extracted cake, although rich in protein cannot be used as cattle fodder because of its toxicity. However, it can be used as a fertilizer. The protein content of castor seed meal varies from 21-48% depending upon the extent of decortications. It has an ideal amino acid profile with moderately high Cystine, mithionine, and isoleucine. But its ant nutritional substances, ricin, ricine and an allergen restrict its use in poultry feed, even at a very low level of inclusion. Castor Cake is an excellent fertilizer because of high content of N (6.4%), Phosphoric Acid (2.55%) and Potash (1%) and moisture retention. There is negative correlation between the contents of ricinine in castor seeds and oil content (r = -0.76). This content of ricinine in castor seed is determined by Agro climatic conditions. Nutrient content of Castor Cake: Organic matter - 75 - 80 %, Nitrogen - 4.0 - 4.5 %, Phosphorous - 1.5 %, Potassium - 1.25 - 1.5 %. It also contains some micro nutrients viz., Calcium, Magnesium, Sulphur, Iron, Zinc, Manganese, Copper etc. A typical composition of castor residue/meal is as follows: Nitrogen - 4% min. approx. Phosphorous - 1% min. approx. Potassium - 1% min. approx. Moisture - 10 - 12 % max. approx. Oil Content - 0.7% max. approx. Advantages: 1.

Ginger root Botanical name: Zingiber officinale Linn. Family: Zingiberaceae. Ginger oil and oleoresins are the volatile oil derived by steam distillation of ginger and oleoresin. It is obtained by percolating the powdered rhizomes of Ginger, Zingiber officinale with volatile solvents. Ginger contains 1-2 percent of volatile oil, 5-8 percent of pungent acrid oleoresin and starch. Zingiberene is the chief constituent in the oil of ginger. Oil is employed for flavoring all kinds of food products and confectionary and finds limited use in perfumery. Oleoresin, commercially called Gingerin contains pungent principles viz. gingerol and shogaol apart from the volatile oil of ginger and is used as an aromatic, carminative, stomachic and as a stimulant. Oleoresin from ginger is obtained conventionally by extraction of dried powdered ginger with organic solvents like ethyl acetate, ethanol or acetone. Commercial dried ginger yields 3.5-10.0 per cent oleoresin. Ginger oleoresin is a dark brown viscous liquid responsible for the flavour and pungency of the spice. Ginger of commerce or `Adrak` is the dried underground stem or rhizome of the plant, which constitutes one of the five most important major spices of India, standing third or fourth, competing with chillies, depending upon fluctuations in world market prices, world market demand and supply position. Ginger, like cinnamon, clove and pepper, is one of the most important and oldest spices. It consists of the prepared and sun dried rhizomes known in trade as `hands` and `races` which are either with the outer brownish cortical layers (coated or unscraped), or with outer peel or coating partially or completely removed. Ginger requires a warm and humid climate. It is cultivated from sea level to an altitude of 1500 meters, either under heavy rainfall conditions of 150 to 300 cm or under irrigation. The crop can thrive well in sandy or clayey loam or lateritic soils. The composition of dry ginger is given below: Dry Ginger rootMoisture:6.9 % Protein:8.6 % Fat:6.4 % Fiber:5.9 % Carbohydrates:66.5 % Ash:5.7 % Calcium:0.1 % Phosphorous:.15 % Iron:0.011 % Sodium:0.03 % Potassium:1.4 % Vitamin A:175 I.U./100 g Vitamin B1:0.05 mg/100 g Vitamin B2:0.13 mg/100 g Niacin:1.9 mg/100 g Vitamin C:12.0 mg/100 g Calorific value:380 calories/100 g. Ginger Oleoresin is obtained by extraction of powdered dried ginger with suitable solvents like alcohol, acetone etc. Unlike volatile oil, it contains both the volatile oil and the non-volatile pungent principles for which ginger is so highly esteemed. Concentration of the acetone extract under vacuum and on complete removal of even traces of the solvent used, yields the so called oleoresin of ginger. Ginger oleoresin is manufactured on a commercial scale in India and abroad and is in great demand by the various food industries.

The manufacture of both granulated and powdered garlic is the same, except for the grinding or powdering process. Granulated garlic is coarse while garlic powder is ground extra fine. Whole cloves of garlic are peeled, cleaned and then sent into a machine that slices and chops them into smaller sections. The sections are dried in slow ovens for three to four hours. When the garlic has cooled it is ground to the desired consistency, be it granulated or powdered. The finished products are put through sifters to separate any debris or undesirable pieces. Both are packaged in air-tight containers and stored in a cool, dry place. Granulated and powdered garlic are used to season and enhance the flavor of many foods. Often it is an appropriate substitute when fresh garlic is called for in a recipe. Powdered garlic dissolves almost instantly when incorporated into any dish, hot or cold. Granulated garlic takes a few minutes to become incorporated and release its flavor.
