Abstract

The invention discloses a method for enhancing the anti-oxidation effect of edible oil by using a natural antioxidant. The method comprises the following steps: S1, separately preparing a powdery aloeextract and a powdery sweet osmanthus extract; S2, adding sesamin into edible oil, and performing uniform stirring; S3, adding the powdery aloe extract and the powdery sweet osmanthus extract into the edible oil in an environment with a temperature of 5-20 DEG C and pressure of 0.2-0.4 MPa, and performing stirring for 30-60 minutes; S4, recovering the pressure to normal pressure, and then gradually increasing the temperature to 60-100 DEG C, and continuing to perform stirring for 10-90 minutes; and S5, performing cooling to a room temperature for preservation. According to the embodiment of the invention, with the method for enhancing the anti-oxidation effect of the edible oil by using the natural antioxidant, the sesame extract, the aloe extract and the sweet osmanthus extract can exertbetter anti-oxidation properties in the edible oil, so that the flavor and the nutritive value of the edible oil are improved.

Description

technical field [0001] The invention relates to the field of food technology, in particular to a method for natural antioxidants to enhance the antioxidant effect of edible oils. Background technique [0002] Due to the influence of light, oxygen and other factors in the external environment, edible oil is prone to automatic oxidation, which will cause the quality of edible oil to deteriorate, lose its original nutritional value and flavor, and even produce harmful substances. In order to avoid this situation, in Adding antioxidants to cooking oils is a simple and effective way. Sesamin, a lignan isolated from sesame seed oil, has several health benefits. Sesamin has been shown to regulate lipid metabolism and reduce body fat. Dietary sesamin has also been shown to be beneficial in improving lipid profiles in humans and animals. At the same time, it is also found in the prior art that sesamin, as a dietary antioxidant, can inhibit the oxidation of low-density lipoprotein ...
