| 摘要 |
The invention discloses a method for enhancing oxidation resistance of edible vegetable oil or fish oil by using a natural antioxidant, which comprises the following step: dissolving the natural antioxidant powder (polyphenol compounds, such as tea polyphenols and carnosic acid) in high-polarity oil (propanediol octanoate) while assisting dissolution with an ultrasonic vortex instrument, wherein the dissolution required lime is directly proportional to the dissolved amount. The natural antioxidant high-load grease has favorable mutual solubility with edible vegetable oil and fish oil, and the addition amount is 10-4000 ppm, thereby obtaining favorable oxidation resistance effect. |
