Abstract

The invention discloses preservative added into foods. The preservative comprises, by volume, 23-28 ml of sodium benzoate, 2-6 ml of butyl-p-hydroxybenzoate, 30-50 ml of propylene glycol, 2-8 ml of fatty acid monoglyceride, 4-10 ml of fructus forsythiae leaf extractives, 0.2-0.8 ml of dehydrated sorbitan esters of fatty acid and 50-60 ml of water. By means of the mode, the preservative added into the foods is low in cost, has the efficient and broad-spectrum antibacterial effect, has the inhibition effect on Escherichia coli, Aspergillus flavus, penicillium chrysogenum, staphylococcus aureus, and can be used for preservation of the foods such as aquatic products, livestock meat, soft drink and noodles.

Description

technical field [0001] The invention relates to the field of preservatives, in particular to a preservative added to food. Background technique [0002] Food preservatives can inhibit microbial activity, prevent food spoilage, and prolong the shelf life of food. Most beverages and packaged foods want to be preserved for a long time, and food preservatives are often added. As far as the sources of food preservatives are concerned, they can be divided into three categories: chemical preservatives widely used at present, plant-derived natural preservatives and animal-derived natural preservatives, among which the latter two types belong to the current research hotspots in the field of food preservatives. Of course, food preservatives are also a "double-edged sword" and may cause certain troubles to people's health. In my country, most of the preservatives currently used in food production are artificially synthesized, and improper use will have certain side effects; some pres...
