Description
Technical field
Food processing field of the present invention, particularly relates to a kind of grease compounded oxidation resistance agent and preparation method thereof.
Background technology
In rural areas in our country, Oleum Gossypii semen is one of edible vegetable oil of common people's major consumers.Oleum Gossypii semen fragrance is pure, fragrant taste, and deep fried products color is good-looking, deeply likes by human consumer.The more important thing is that Oleum Gossypii semen is of high nutritive value, the lipid acid containing a large amount of needed by human, be not rich in linolic acid (40-45%) containing cholesterol, can effectively suppress Blood Cholesterol to rise, alleviate hyperlipemia, safeguard the health of human body.Human body is 98% to the digestibility of Oleum Gossypii semen.
But, easily there is oxidative rancidity under the effect of grease oxygen, illumination, enzyme and microorganism in atmosphere.Research shows, edible rotten grease and fat-containing food can cause heart and brain atherosclerosis, cancer, accelerate human senescence, very unfavorable to health.At present, synthetized oxidation preventive agent BHA, BHT and TBHQ etc. are generally used both at home and abroad.But have a large amount of experimentation on animals to show in recent years, synthetized oxidation preventive agent has certain toxicity and carcinogenesis when heavy dose uses.Natural antioxidants is used to replace synthetized oxidation preventive agent to become the trend of Future Development.
Recent domestic scholar has found many crude substance with antioxygenation, but their oxidation-resistance is not as synthetized oxidation preventive agent.Due to many-sided reasons such as performance, source, extracting method, prices, natural antioxidants still cannot replace synthetic antioxidant within a quite long period.
Summary of the invention
The shortcoming of prior art in view of the above, the object of the present invention is to provide a kind of grease compounded oxidation resistance agent and preparation method thereof.
