Compound plant source fruit and vegetable fresh keeping agent and preparation method thereof

Abstract

The invention provides a compound plant source fruit and vegetable fresh keeping agent and a preparation method thereof. The fresh keeping agent is prepared from the following plant extract and wateringredients in dosage proportion: 5 to 15 percent of liquorice roots, 10 to 20 percent of rhizoma galangae, 10 to 20 percent of rhizoma coptidis, 5 to 15 percent of fructus cnidii, 10 to 20 percent offructus litseae cubebae and 10 to 60 percent of pure water. The compound matched plant fresh keeping agent provided by the invention is a broad-spectrum efficient and antibacterial natural fresh keeping agent formed through two rounds of screening from hundreds of species of natural plant extracts by a combined screening platform technology; the natural fresh keeping agent has specific matching rules and can take synergistic interaction during the combination by different dosages; by the fresh keeping agent, the preservative and fresh-keeping time of various fruit and vegetables can be increased; no poison, no harm and no residue exist; the green and natural effects are achieved; the eating is safe. The preparation method is simple; the implementation is easy; the cost is low; industrialdevelopment values are realized.

Description

technical field [0001] The invention relates to the field of fresh-keeping of fruits and vegetables, in particular to a composite and compatible plant-source fruit and vegetable fresh-keeping agent and a preparation method. Background technique [0002] During the post-harvest storage and transportation of fresh fruits and vegetables, due to the infection of various pathogenic microorganisms and metabolic activities such as ethylene respiration, the fruits and vegetables will rot and deteriorate, causing huge economic losses. According to incomplete statistics, the annual fruit and vegetable rot loss rate in my country reaches 30% to 50%. The most commonly used methods in production are physical methods such as refrigeration and air conditioning, and chemical fungicide treatment. Physical methods such as low temperature and controlled atmosphere have problems such as high cost, high energy consumption, and imperfect facilities, while chemical residues endanger human health,...

AI Technical Summary

Problems solved by technology

The research on fresh-keeping technology of natural plant sources in my country started relatively late, the technical force is weak, and the compound technology lags behind. Most of the research focuses on the antibacterial properties of single plant extracts and some simple compound plant extracts. The research on the antibacterial mechanism and toxicity is not fine and in-depth, and it is difficult to apply it to a dynamic and changing environment where a variety of microorganisms coexist, and industrialization has not yet taken shape.
