Embodiment Construction

[0028] Below in conjunction with specific embodiment, further illustrate the present invention. The following examples should be understood as only for illustrating the present invention but not for limiting the protection scope of the present invention. After reading the contents of the present invention, those skilled in the art can make various modifications or changes to the present invention, and these equivalent changes and modifications also fall within the scope defined by the claims of the present invention.

[0029] Forsythiaside A and citric acid composition prepared oil quality retaining agent, the weight ratio of forsythiaside A and citric acid in the oil quality retaining agent is 1:1, and the addition amount of oil quality retaining agent is 0.08% of the oil mass. The mass fraction of the forsythiaside A is 96%. Its preparation steps are:

[0030] 1) Extraction: Take 50g of fresh forsythia leaves and spread them out at room temperature until the water content...

Abstract

The invention discloses an oil quality preserving agent prepared from forsythiaside A and citric acid. The weight ratio of forsythiaside A and citric acid in the oil quality maintaining agent is 1:1. The specific preparation steps Including: extraction, resin separation, precipitation separation, purification and composition preparation. The preparation method itself has simple operation, mild process conditions, high separation efficiency, high utilization rate of forsythia leaves, high purity and good quality of the finished product. The results of the composition auxiliary oil antioxidant activity test show that: compared with forsythiaside A and citric acid when used alone, the composition has a strong inhibitory effect on the oxidation of various oils, and shows obvious synergy Synergistic anti-deterioration effect. At the same time, forsythiaside A is a natural product, and citric acid is a normal metabolite of the human body. Therefore, the composition is less toxic than artificially synthesized oil quality maintaining agents, has high safety, good stability, and a wide range of applications. Develop application prospects.

Description

technical field [0001] The invention relates to the technical field of preparation of a novel composition additive or an additive, in particular to the application of a composition of forsythiaside A and citric acid in the preparation of a grease quality retainer. Background technique [0002] Grease and oil-rich foods are stored for too long or used improperly under unsuitable storage conditions, and they are prone to produce a strong pungent odor. This phenomenon is called rancidity of oil. The oxidative rancidity of oil or fat in food is not only related to its own properties, but also related to external factors such as temperature, humidity, air and light, enzymes and certain metal ions. [0003] 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. Antioxidants refer to a cl...
