Antioxidant sesame oil and preparation method thereof

Abstract

The invention provides antioxidant sesame oil and a preparation method thereof. The preparation method comprises the following steps: pouring sesame into steeping oil, carrying out ultrasonic steepingtreatment, filtering, crushing, thinning, uniformly spraying the steeping oil, standing, steeping and squeezing to obtain crude oil, adding a catalyst into the crude oil, carrying out stirring reaction, and carrying out post-treatment to obtain the antioxidant sesame oil, so that the antioxidant property of the sesame oil can be improved without additionally adding an artificially synthesized antioxidant. In the oil preparation process, on one hand, loss of tocopherol substances and sesamin is avoided, on the other hand, sesamin is promoted to be converted into sesamol, sesamol and sesamol, and according to research, sesamol and vitamin E have a synergistic effect, and oxidation resistance is enhanced.

Description

technical field

[0001] The invention relates to the technical field of food processing, in particular to an antioxidant sesame oil and a preparation method thereof. Background technique

[0002] Sesame oil, which is extracted from sesame, has a special fragrance and is an indispensable seasoning in people's daily diet. It can be used in cold dishes, hot dishes or soups. Sesame oil is rich in vitamin E, carotene, saturated and unsaturated fatty acids, phospholipids, sterols, stigmasterol, campesterol, cycloartenol, squalene, etc. Among the fatty acids in sesame oil, unsaturated fatty acids account for about 84%, and the digestion and absorption rate is as high as 98%. Sesame oil has many benefits to human health, such as: delaying aging, protecting blood vessels, laxative, reducing tobacco and alcohol poisoning, protecting throat, treating rhinitis, removing freckles and moisturizing skin, etc.

Embodiment 1

[0036] A preparation method of antioxidant sesame oil, the specific steps are as follows:

[0037] (1) Preparation of steeping oil: firstly crush hawthorn seeds and quinoa respectively and mix them into a mixed powder, then add the mixed powder into petroleum ether, perform ultrasonic extraction, filter, take the filtrate, and remove petroleum ether to obtain the steeped oil ;

[0038](2) Preparation of the catalyst: first mix tetraethyl titanate with absolute ethanol, glacial acetic acid, and deionized water to hydrolyze with stirring, then slowly add the ethanol solution of zinc acetate dropwise, oscillate evenly with ultrasonic waves, remove ethanol, and freeze-dry to obtain said catalyst;

[0039] (3) Pour the sesame seeds into the impregnation oil obtained in step (1) and carry out ultrasonic impregnation treatment, filter, pulverize, spray the impregnation oil evenly after thinning, leave to stand for impregnation, and squeeze to obtain crude oil;
