Palm oil is derived from the flesh of the fruit of the oil palm species E. Guineensis. In its virgin form, the oil is bright orange - red due to the high content of carotene.
Palmoil is semi - solid at room temperature; a characteristic brought about by its approx. 50 percent saturation level. Palm oil (and its products) has good resistance to oxidation and heat at prolonged elevated temperatures; hence, making palm oil an ideal ingredient in frying oilblends. Manufacturers and end - users around the world incorporate high percentages of palm oil in their frying oil blends for both performance and economic reasons.
In fact, in many instances, palm oil has been used as 100 percent replacement for traditional hydrogenated seed oils such as soybean oil and canola. Products fried in palm oil include potato chips, frenchfries, doughnuts, ramen noodles and nuts.
The oil palm produces two types of oils; crude palm oil (CPO) from the fibrous mesocarp and crude palm kernel oil (CPKO) from the kernels. Although both oils originate from the same fruit, palm oil is chemically and nutritionally different from palm kernel oil. It is one of the only two mesocarp oils available commercially, the other being olive oil.
In conventional milling process, the FFB's are steriliszed and the fruitlets stripped off. The loose fruitlets are then digested and pressed to extract the CPO. The kernels are separated from the fibrous mesocarp in the press cake and later cracked to obtained CPKO.
CHEMICAL COMPOSITION OF PALM OILS:
Crude Palm Oil is the richest natural source of Tocotrienols. The Malaysian Palm Oil Board (MPOB) has developed a special patented technology for extraction. The latest technology to purify Tocotrienols from the fruits of oil palm (Elais guineensis) was developed to produce a superior quality and purity.
PALM OIL
Palm oil, being a vegetable oils, is cholesterol - free. Having a naturally semi solid characteristic at room temperature with a specific origin melting point between 33'C to 39'C, it does not require hydrogenation for use as a food an ingredient.
CPO is deep orange red in colour due to the high content of natural carotenes. Palm oil is rich source of carotenoids and vitamin E which confers natural stability against oxidative deterioration.
Fractionation separates oil into liquid and solid fractions. Palm oil can be fractionated into liquid (olein) and solid (stearin) components.
Palm oil has a balanced ratio of unsaturated and saturated fatty acids. It contains 40% oleic acid (monounsaturated fatty acid), 10% linoleic acid (polyunsaturated fatty acid ), 45% palmitic acid and 5% stearic acid (saturated fatty acid). This composition results in an edible oil that is suitable for use in a variety of food applications.

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.

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.

Guar gum is a fiber from the seed of the guar plant.
Guar gum is used as a laxative. It is also used for treating diarrhea, irritable bowel syndrome (IBS), obesity, and diabetes; for reducing cholesterol; and for preventing “hardening of the arteries” (atherosclerosis).
In foods and beverages, guar gum is used as a thickening, stabilizing, suspending, and binding agent.
In manufacturing, guar gum is used as a binding agent in tablets, and as a thickening agent in lotions and creams.
How does it work?
Guar gum is a fiber that normalizes the moisture content of the stool, absorbing excess liquid in diarrhea, and softening the stool in constipation. It also might help decrease the amount of cholesterol and glucose that is absorbed in the stomach and intestines.
There is some interest in using guar gum for weight loss because it expands in the intestine, causing a sense of fullness. This may decrease appetite.
USES:
Diarrhea. Adding guar gum to the tube feeding formula given to critical care patients may shorten episodes of diarrhea from about 30 days to about 8 days.
High cholesterol. Taking guar gum seems to lower cholesterol levels in people with high cholesterol. Guar gum and pectin, taken with small amounts of insoluble fiber, also lower total and “bad” low-density lipoprotein (LDL) cholesterol, but don't affect “good” high-density lipoprotein (HDL) cholesterol or other blood fats called triglycerides.
Diabetes. Taking guar gum with meals seems to lower blood sugar after meals in people with diabetes. By slowing stomach emptying, guar gum may also lessen after-meal drops in blood pressure that occur frequently in people with diabetes.
Constipation.
Irritable bowel syndrome (IBS).
