Abstract

The invention discloses a vegetable fresh-keeping composition containing fructus forsythiae leaf extract. The composition is prepared from the following raw materials by weight: 2.5 parts of the fructus forsythiae leaf extract, 1 part of sodium dehydroacetate and 1 part of potassium sorbate. A preparation method for the composition has the advantages of simple operation, mild process conditions, high separation efficiency, a high utilization rate of fructus forsythiae leaves, high purity and good quality of a finished product and capacity of meeting needs of industrial large-scale production. According to results of activity tests of the composition in assistant preservation and fresh-keeping of vegetable, the composition has substantial preservative and fresh-keeping capability and presents a strong fresh-keeping effect and an obvious synergistic effect compared with a natural preservative and a chemical preservative which are individually used. Since the composition is prepared by compounding the fructus forsythiae leaf extract which is used as a natural product and a chemical preservative, the composition provided by the invention has higher security and wide development and application prospects compared with artificially synthesized preservatives.

Description

technical field [0001] The invention relates to a novel composition additive or the technical field of preparation of the additive, in particular to the use of a composition containing forsythia leaf extract in preparing vegetable preservatives. Background technique [0002] During the process of picking, storing, processing and consuming fresh fruits and vegetables, they are easily spoiled, causing huge waste of resources and economic losses. While decaying and losing, pathogenic microorganisms can also produce toxins, endangering people's health. According to incomplete statistics, about 10% to 20% of fresh fruits and vegetables in developed countries are rotten due to microorganisms, and the proportion in developing countries is as high as 40% to 50%. The output of perishable characteristic fruits in China is about 116 million tons, the postharvest loss is about 25%~30%, and the economic loss is about 70 billion yuan. Therefore, during the storage of fruits and vegetabl...
