Abstract

The invention provides a composite plant extract. The composite plant extract comprises a clove lilac extract, a rosmarinus officinalis extract, a liquorice extract and an origanum vulgare extract. Effective ingredients of the composite plant extract provided by the invention are all derived from natural plant extracts, including the clove lilac extract, the rosmarinus officinalis extract, the liquorice extract and the origanum vulgare extract; proven by actual test results, the composite plant extract has an effective bacteriostatic and bactericidal effect on food-borne pathogenic bacteria; furthermore, the composite plant extract is derived from natural plants, thus, is harmless to human bodies and has a safe and efficient antibacterial effect; the composite plant extract can be appliedto food freshness preserving, food equipment and environments; the composite plant extract can replace the traditional chemical freshness keeping agents and has an important practical significance inreducing chemical residues, protecting the environments, guaranteeing human health, prolonging storage lives of vegetables and the like.

Description

Technical field [0001] The invention relates to the technical field of food safety, in particular to a composite plant extract, preparation method and application. Background technique [0002] "Food is the heaven for the people, and food safety is the first." Food safety has become the focus of attention of the whole society. Long-term storage of food will cause spoilage due to the breeding of food-borne pathogens. Spoilage will not only cause food to lose its nutritional value, but also cause food poisoning, resource loss and environmental pollution. [0003] In order to inhibit and eliminate food-borne pathogenic bacteria, it is often necessary to add antiseptic preservatives to food to achieve antiseptic and antiseptic properties and extend the shelf life of food. However, most of the antiseptic preservatives currently used are chemical antiseptics and have certain effects on the human body. harm. As people pay more and more attention to food safety, this kind of chemical ant...
