Problems solved by technology

[0003] Plant essential oils are mostly water-insoluble components, which are difficult to be directly used in food production. Usually, emulsification is used to increase their solubility. However, the particle size of conventional emulsions is large, and the actual use effect is not good, and it is prone to adverse phenomena such as demulsification and oxidation.

preparation example Construction

[0031] The preparation method of star anise essential oil is for example: get dry star anise (moisture content≤5%), cross 40 mesh sieves after pulverizing, take dry powder, 10 parts by weight, pack into filter paper bag, add dehydrated alcohol 100 parts (ie , the material-to-liquid ratio is 10g / 100ml), heated in a water bath at 70°C, and circulated until the color of the new leachate no longer changes. Take out the leachate, remove absolute ethanol by vacuum distillation, and add a small amount of anhydrous sodium sulfate for dehydration, which is star anise essential oils.

[0032] Changing the star anise into cloves and spearmint, and preparing according to the above method, clove essential oil and spearmint essential oil can be obtained correspondingly.

[0033] The preparation method of garlic water extract is as follows: Weigh fresh garlic, 10 parts by weight, add 10 parts of sterile distilled water of equal weight, use a wall breaker to crush it for 5 minutes, take it ou...

Embodiment 1

[0035] A plant extract compound antibacterial agent, the raw materials are calculated according to the mass ratio, and the formula is: 5 parts of star anise essential oil, 5 parts of clove essential oil, 5 parts of spearmint essential oil, 5 parts of isopropyl myristate, garlic water extract 10 parts, 0.5 parts of lactic acid, 100 parts of distilled water, 15 parts of Tween-80, 15 parts of RH-40 and 15 parts of absolute ethanol.

[0036] Its preparation method is to carry out the following steps successively:

[0037] S1. Accurately weigh star anise essential oil, clove essential oil and spearmint essential oil, and after mixing, 30 kHz ultrasonic wave for 10 minutes, so that the essential oils are fully dissolved in isopropyl myristate to obtain an oil phase;

[0038] S2. Accurately weigh the garlic water extract and lactic acid, dissolve in distilled water to obtain the water phase;

[0039] S3. Slowly add co-emulsifier anhydrous ethanol to the oil phase (adding time is abo...

Embodiment 2

[0042] Embodiment 2, a kind of plant extract compound antibacterial agent, raw material according to mass ratio, formula is: 6 parts of star anise essential oil, 6 parts of clove essential oil, 6 parts of spearmint essential oil, 6 parts of isopropyl myristate, 12 parts of garlic water extract, 0.6 parts of lactic acid, 100 parts of distilled water, 15 parts of Tween-80, 15 parts of RH-40 and 15 parts of absolute ethanol.

[0043] The preparation method is identical to Example 1.

Abstract

The present invention discloses a plant extract compound bacteria-reducing agent. The plant extract compound bacteria-reducing agent is composed of the following components in parts by weight: 5-10 parts of star anise essential oil, 5-10 parts of clove essential oil, 5-10 parts of spearmint essential oil, 5-10 parts of isopropyl myristate, 10-20 parts of a garlic water extract, 0.5-1 part of lactic acid, 80-160 parts of distilled water, 15-30 parts of Tween 80, 15-30 parts of RH-40 and 15-30 parts of absolute ethyl alcohol. The present invention also discloses a preparation method of the plant extract compound bacteria-reducing agent. The plant extract compound bacteria-reducing agent has obvious bacteria-preventing and bacteria-reducing effects on food-borne bacteria commonly found in life, such as escherichia coli, staphylococcus aureus, bacillus subtilis, candida albicans, shigella dysenteriae, etc.

Description

technical field [0001] The invention relates to the technical field of food antibacterial, in particular to a plant extract compound antibacterial agent and a preparation method thereof. Background technique [0002] Food is inevitably contaminated by microorganisms during storage and use. In order to prolong the food preservation period, people use different methods to inactivate microorganisms, delay or prevent their growth, and adding preservatives is a convenient, effective and widely used method. The currently used food preservatives are mainly chemical preservatives such as benzoic acid, sorbic acid and their salts, parabens, etc. Although chemical preservatives have a certain inhibitory effect on microorganisms, most of them have certain physiological toxicity , Long-term accumulation will lead to decline in human body function, and even serious health problems. Therefore, the research and development of natural preservatives that are easy to use, effective and have...
