Soybean Oil – one of the most concentrated sources of Omega 6

A soybean seed contains about 19 % Oil. To extract soybean oil from seed the soybeans are cracked, adjusted for moisture content, rolled into flakes and then solvent-extracted. Soybean oil ends up in a wide variety of processed foods and most but not all oils in shops labeled ‘Vegetable Oil’ are Soybean oil. Soybean oil is among the healthiest of all edible oils and has a very favorable fatty acid profile. It is low in saturated fat, high in polyunsaturated fat and contains monounsaturated fat. This oil is highly digestible and contains no cholesterol.

Long recognized as nutritionally balanced, versatile and affordable, soybean oil is one of the few non-fish sources of omega-3 polyunsaturated fatty acids, which have various physiological benefits including cardioprotective effects. Omega-6 fatty acids, also found naturally in soybean oil, may help decrease risk of heart disease. Containing about 50 percent omega-6 fatty acids, soybean oil is one of the most concentrated sources of this polyunsaturated fat. Soybean oil is the primary commercial source of alpha-tocopherol, also known as vitamin E. Vitamin E is the body’s primary lipid-soluble antioxidant defense against free radical induced cell damage, which has been linked to a number of cancers, heart disease, cataracts, premature aging and arthritis.

The neutral flavor and well-balanced fatty acid profile of soybean oil make it a desirable ingredient for a variety of applications from baked goods to salad dressings. Soybean oil can be used in breads, crackers, barbecue sauce and non-dairy creamers. Soybean oil is used in prepared foods such as whipped toppings, sandwich spreads, non-dairy coffee creamers, potato chips and battered and breaded snacks and vegetables. Compared to other vegetable oils, soybean oil has good emulsifying ability. This makes it an appropriate ingredient in mayonnaise, and the first choice of the general food industry. Almost all margarine and shortenings contain soybean oil. Soybean oil can turn two ounces of olive oil into a whole pint of flavored oil for dressings. The distinctive olive oil aroma will be evident, even though the bulk of the dressing’s oil component comes from inexpensive soybean oil.

Soybean oil has a high smoke point of 440°F which allows it to be used as frying oil. Soybean oil is often hydrogenated to increase its shelf life or to produce a more solid product. In this process, unhealthy trans fats are produced which raise blood cholesterol levels and increase the risk of heart disease. Food manufacturers are now trying to remove trans fats from their product. For this purpose, scientists are breeding new varieties of soybeans containing oil that does not need to be hydrogenated.

Soybean oil contains natural antioxidants which remain in the oil even after extraction. These antioxidants help to prevent the oxidative rancidity. Soybean oil has normally a shelf life of 1 year but its better to store the soybean oil only a few months at room temperature. Soybean oil should be stored in a dry and dark place. It should be stored away from heat and if you want to keep soybean oil for longer periods it should be kept refrigerated.
