In recent two years, high oleic sunflower seed oil, high oleic peanut oil and high oleic rapeseed oil began to appear on the shelves of domestic supermarkets. In fact, high oleic acid edible oil has already appeared in foreign markets. ADM, Cargill, Bunge and other international grain and oil giants not only continue to introduce a variety of high oleic oil to the consumer market, but also actively cooperate with agricultural companies such as DuPont and Monsanto to promote the breeding and planting of high oleic oil.
"High oleic acid" has become an important direction of consumption upgrading of edible oil products.
Oleic acid and high oleic acid edible oil
The edible oil that people yearn for is: the content of saturated fatty acid is very low, and it does not contain trans acid, which helps to reduce the occurrence of cardiovascular diseases and can be preserved for a long time. These are precisely the charm of high oleic vegetable oil.
Oleic acid, which nutritionists call "safe fatty acid", is a monounsaturated omega-9 fatty acid, which exists in animals and plants and is also the most abundant fatty acid in human adipose tissue.
In animal fat, oleic acid accounts for about 40%-50%; The oleic acid content of different vegetable oils is different: tea oil can reach 83%, olive oil 55-80%, peanut oil 36-67%, sesame oil 15-20%. The oleic acid content of soybean oil is about 2 1%.
In terms of health, oleic acid is a monounsaturated fatty acid, which can reduce the low-density lipoprotein cholesterol in human body and reduce the occurrence of cardiovascular diseases. Therefore, vegetable oil with high oleic acid content is considered to be healthy.
At the same time, oleic acid is a chemically stable substance, which can be preserved for a long time without hydrogenation. The liquid stability of high oleic acid edible oil from production to sales is 5 times that of crude oil10-/kloc-0, which can prolong the shelf life of oil and fat.
Rapid development of high oleic acid edible oil
In the American market, sunflower oil with high oleic acid first appeared, and now it accounts for more than 15% of the sunflower oil market. The high oleic sunflower seed oil in the market contains 80-84% oleic acid, which can sometimes reach 88-89% due to the influence of climate and other conditions. This oil is not only high in oleic acid, but also low in saturated fatty acids and polyunsaturated acids.
Dow Agronomy Company of the United States has developed a sunflower seed oil with high oleic acid and no saturated fat. The saturated fat content in each person's meal-sharing recipe does not exceed half a gram.
And high oleic rapeseed oil. Cargill Company of the United States produces and sells two kinds of high oleic rapeseed oil-Gu 65 (containing 65% oleic acid, mainly used for fried food) and Qing Gu 80 (containing 80% oleic acid, mainly used for baked food). Cargill also provides high oleic acid sunflower seed oil.
"Consumers have a high demand for detailed labels and health products, which has promoted the growth of high oleic rapeseed oil and sunflower oil," said Cargill's special oil production manager.
