Salad oils additives

The US imports large amounts of canola oil from Canada in addition to some domestic production. Currently, about 90% of the canola oil is consumed in liquid form as salad oil and in salad dressings. This is a direct result of the emphasis on consuming oils which are low in saturated fatty acids and canola oil is lowest in saturated fat among vegetable oils. Canola oil is also being used in blended salad oils to achieve certain fatty acid profiles, as mentioned earlier. The relatively high use of canola oil in the US is remarkable, since none was used before 1983. 

In addition to the above analysis, it is recommended that any refiner of sunflower oil should also check the following micro components because they indicate the true quality of the oil as salad oil or as other finished products such as margarine and shortening. 

Products and Uses A basic ingredient in soaps, detergents, bubble baths, lipstick, candles, salad oils, shortenings, and cosmetics. A component in the manufacture of food-grade additives, as a defoaming agent, lubricant, emulsifier, and binder. 

In vitro test, ss has antiperoxidation.(9) Oxygen was infused into the compound of ss and salad oil. After heating the compound for 40 min,the compound was measured to see the amound of peroxide lipid, with result that the compound with ss produced less peroside lipid than that without ss. In addition,the content of SOD in serum of experimental diabetes rats(DM) fed on forage contained ss increased,while the peroside lipid and free radical amount decreased. Thus the damage of peroxide lipid to endothelial cells was decreased, and the deterioration of DM rats angiopathy was postponed or prevented. It is thus inferred that ss inhibits lipid peroxidation by inhibiting the onset period of peroxidation. 

The worldwide consumption of soybean oil was 37.9 million tons in 2008, accounting for 28% of global vegetable oil usage [1]. It finds its way into several food appHcations such as cooking oils, salad oils, or margarines. Technical uses include additives for coatings. In the biofuels industries of the United States and Brazil, soybean oil is also the main feedstock for biodiesel production (almost 20% of soybean oil went into biodiesel in the United States in 2008 [7]).

The physical state of fats and oils and their crystal structures are important for application of such products. In addition, formulation of products for special applications such as bakery, confectionary, frying, salad dressing, margarines, and spreads requires special characteristics that make the products suitable for such purposes. Thus, each source material will be important for its physical and chemical characteristics and hence suitability as a food component.
