Description

technical field

[0001] The invention relates to the technical field of preparation of novel additives or additives, and in particular relates to the use of forsythiaside A in the preparation of oil quality maintaining agents. Background technique

[0002] Oil (or fat) is one of the three essential nutrients for the human body. If oil and oil-rich foods are stored for a long time or used improperly under inappropriate storage conditions, a strong pungent odor is likely to be produced. The phenomenon is called rancidity of fat. In order to ensure the quality of the oil during storage, prolong its shelf life, and prevent deterioration, some additives are usually added to the oil. One of the most essential functions of oil and fat quality preserving agents is anti-oxidation. Special antioxidants are usually added to oils to improve the antioxidant properties of oils. Antioxidants refer to a class of food additives that can prevent or delay the oxidative deterioration of food ...
