Abstract

The invention belongs to the preparation field of food antibacterial agents and particularly relates to a preparation method and an application of a compound antibacterial agent. The preparation method comprises the following specific steps: (1) preparing an origanum majorana extract: cleaning origanum majorana leaves, shearing, drying, adding absolute ethyl alcohol for soaking, carrying out shaking out and digestion, putting the origanum majorana leaves into a pulsed magnet field instrument, carrying out pulsed magnet field treatment, filtering, and concentrating, so as to obtain the origanummajorana extract; and (2) preparing the compound antibacterial agent: mixing the origanum majorana extract, sodium diacetate, hinolitol, polylysine hydrochloride and sterile distilled water, so as toobtain the compound antibacterial agent. According to the preparation method, the compound antibacterial agent is prepared by mixing the origanum majorana extract with sodium diacetate, hinolitol, polylysine hydrochloride and sterile distilled water in a certain proportion, so that the preparation cost of the compound antibacterial agent can be lowered, and the antibacterial performance of the compound antibacterial agent can be improved. The compound antibacterial agent prepared by virtue of the preparation method has a good antibacterial effect in the application of fruits, vegetables and meat.

Description

technical field [0001] The invention belongs to the field of preparation of food antibacterial agents, and in particular relates to a preparation method and application of a composite antibacterial agent. Background technique [0002] In recent years, there are many kinds of antibacterial agents circulating in the market, but most of them contain toxic chemical reagents, such as hypochlorous acid, peracetic acid, glutaraldehyde, etc., and there are certain hidden dangers in use. In this context, the field of food safety needs a natural and safe antibacterial agent with broad-spectrum antibacterial properties. [0003] Marjoram (Origanum majorana) is a perennial herb that likes a sunny, warm and humid environment, and is widely distributed in the Mediterranean region. Marjoram is aromatic, with sweet pine and citrus aromas, and is a commonly used spice in dishes. Stem and leaf all contain volatile oil, main component is thymol (Thymol) and carvacrol (Carvacrol). In additio...
