Fats and Oils for Human Consumption

Fats and oils for human consumption are usually separated into 3 categories: salad and cooking oils, frying oils, and solid fats. The quality issues of edible oils include oxidative stability, nutrient composition, and functionality.

Salad and Cooking Oils

Bland flavor, light color, good stability, and manufacturing processing and packaging flexibility are important for salad and cooking oils. Good choices to meet these requirements are polyunsaturated and monounsaturated oils. Less polyunsaturated fat is preferred to minimize the likelihood of rancidity and the need for refrigeration. This type of salad or cooking oils also is suitable for in-home 1-time deep frying and pan frying. The need for trans fatty acid reduction in this type of liquid oils is not an issue because most salad or in-home cooking oils on the market today do not contain trans fatty acids and cooking this type of oil in one’s kitchen does not produce trans fatty acids.

Frying Oils

Commercial frying applications include restaurant frying such as the preparation of deep-fried foods and packaged foods such as snack chips.

Oils for commercial frying require stability related to the thermal deterioration processes of oxidation, hydrolysis, and polymerization. For consumer acceptance, the fatty acid composition of the oils needs to have 20% to 30% linoleic acid to produce a desirable full deep-fried flavor to the foods; however, higher levels of linoleic acid might introduce "off"-flavors from oxidation. For restaurant use, oils need to be stable because a long fry life is required and the oil has to withstand the high temperatures of commercial frying.

Food manufacturers prefer stable oils that can also tolerate high temperatures and allow an extended shelf life for foods after they are packaged.

Stable frying oils are characterized by increased amounts of oleic acid (preferably in the moderate range of 50% to 65%), decreased amounts of linoleic acid (preferably in the 20% to 30% range), and decreased amounts of linolenic acid (preferably no more than 3%). It has been common to acquire stable commercial frying oils by changing the fatty acid composition by partial hydrogenation. Potential alternatives to partially hydrogenated oils for commercial frying include naturally stable oils such as corn, cottonseed, palm, peanut, and rice bran and modified fatty acid oils such as mid-oleic corn, high-oleic/low-linolenic canola, high-oleic sunflower, mid-oleic sunflower, low-linolenic soybean, and mid-oleic/low-linolenic soybean oils . In choosing trans fatty acid–free frying oils, consider the cost, availability, oxidative stability, functionality in terms of the appearance and texture, flavor, and nutrient composition of the option. Specifically, some of these oils such as animal fats and tropical oils contain high amounts of saturated fats and should not be considered as replacements.

Indian Oilseeds & Oils Production

Total Oilseed for 2010-11 forecast at 34.9 million tons up from 31.7 mmt 2009-10e- Edible oil production 2009-10e at 6.2 mmt while 2010-11 forecast at 7 million tons

Assuming a normal monsoon and favorable growing conditions, total oilseed production in 2010/11 is forecast at 34.9 million tons, up 3.2 million tons over the 2009/10 production estimate. Poor monsoon rains and floods in major growing oilseed growing regions have brought down the total oilseed production in 2009/10 to 31.7 million tons.

Soybean production for 2008-09 was 9.1 million tons. Rapeseed production for 08-09 was 6.7 million tonnes, sunflower 1 million tons.

Oil meal exports are estimated at 3.05 million tons, while edible oil imports in 2009/10 were 8.6 million tons (includes 6.95 million tons of palm oils, 1 million tons of soy oil, 600,000 tons of sunflower oils).

Edible oil production in 2009/10 is estimated at 6.2 million tons which includes 2.1 million tons of rapeseed oil, 1.25 million tons of peanut oil, 1.06 million tons of soybean oil, and 1.04 million tons of cottonseed oil, and 744,000 tons of coconut palm and sunflower oils.

while imports are estimated at 8.6 million tons (6.95 million tons of palm oils, 1 million tons of soy oil, 600,000 tons of sunflower oil and 40,000 tons of other edible oils).

Edible oil production in 2010/11 is forecast at 7 million tons, up 13 percent over 2009/10 with most of the increase expected in peanut, rapeseed, and soybean oil.

Consequently, the consumption is also forecast to increase by 5 percent at 15.7 million tons.During the first five months of 2009/10, the total sales commitment of U.S. origin soy oil to India was 108,300 tons, which was almost 25 percent of India’s total soy oil import to date.

India imports its soybean oil from Argentina, Brazil and U.S. U.S. contributes 25% of Indian soy oil imports.

Crude oil zero duty while refined oil 7.5% dutyPeanut exports in 2010/11 are forecast to increase by 80,000 tons to 250,000 tons due to anticipated higher production and improving quality of Indian Hand Picked Select (HPS) peanuts.

Peanut export estimate in 2009/10 is revised down by 90,000 tons to 170,000 tons.

Indonesia, Malaysia, Philippines, UAE, Pakistan, Singapore, United Kingdom, Sri Lanka and Ukraine are major export destination for Indian peanuts.Anticipating higher domestic production of sesame seed in 2009/10, exports are estimated to be 250,000tons, up 60,000 tons over 2008/09.

Taiwan, U.S.A, South Korea, Vietnam, China, Netherlands, Germany, Greece, Malaysia and Turkey are major export destinations for Indian sesame seed.

Total feed use in 2010/11 is forecast to increase by 1.1 million tons to 11.5 million tons, this would include 3.6 million tons of cottonseed meal (mostly used in livestock feed), 2.75 million tons of rapeseed meal, 2.7 million tons of soybean meal, 1.8 million tons of peanut meal, and 650,000 tons of other oil meals.

Almost 70 to 80 percent of total oilseed production is crushed for oil while the balance quantity goes for food, feed and seed use.

SBM constitutes more than 70% of the total oilmeals export from India. Indian rapeseed meal is finding wide acceptance as organic manure.
