Embodiment

[0051] A compound plant-derived preservative consisting of plant extracts and solvents;

[0052] Each mL of preservative contains 48.00mg of green tea extract, 27.38mg of scutellaria baicalensis extract, 57.37mg of longan seed extract and 44.21mg of myrtle fruit extract;

[0053] The solvent is propylene glycol solution, and its volume percentage is 2-5%.

[0054] Described green tea extract is made by the following steps:

[0055] (1) Dry the green tea in an oven until it becomes brittle, pulverize it, pass through a 60-mesh sieve, take a certain amount of green tea dry powder, and use 50% to 70% ethanol aqueous solution (volume fraction) to calculate the solid-to-liquid ratio kg / L as 1: Extract at 8-20 hours, suction filter after 18-24 hours, then continue to use the above solvent to repeatedly extract and filter the filter residue twice, and finally combine the three times of filtrates, then concentrate them to the extract by rotary evaporation, and store them in a refrige...

Abstract

The invention discloses a compound type plant source preservative optimized by response surface method and its application. The preservative is composed of plant extract and solvent; each mL of preservative contains 48.00 mg of green tea extract and 27.38 mg of Scutellaria baicalensis extract mg, longan seed extract 57.37mg and myrtle fruit extract 44.21mg. The preservative of the present invention has a good antibacterial and antiseptic effect, and the 4 kinds of plant extracts contained in it have a certain synergistic effect, which broadens the antibacterial spectrum of a single plant, makes it have a wider antibacterial spectrum, and can effectively inhibit Microorganisms such as Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, Bacillus subtilis, Candida albicans and Aspergillus niger. In addition, the preparation of the preservative adopts the response surface method, which can more intuitively reflect the interaction between the compound components.

Description

technical field [0001] The invention belongs to the field of plant preservatives, and in particular relates to a compound plant source preservative optimized and combined by response surface method and its application. Background technique [0002] At present, most of the preservatives used in food and cosmetics on the market are chemically synthesized preservatives, and the safety of chemically synthesized preservatives has been increasingly questioned. [0003] With the development of detection technology and the improvement of people's safety awareness, natural preservatives are favored by the public. Plant-derived preservatives have become a research hotspot in the current development of natural preservatives because of their rich resources, convenience and other advantages. [0004] Chinese patent ZL 201610745209.X discloses a stevia phenolic extract and its application in the preparation of antibacterial products. Because it is a unit (or single taste, single dose) p...
