Description

Edible fungus fresh-keeping plant essential oil composition and preparation method of microemulsion coating liquid thereof Technical Field The invention belongs to the technical field of plant essential oil compositions, and particularly relates to a preparation method of a plant essential oil composition for preserving edible fungi and a microemulsion coating liquid thereof. Background Edible fungi are rich in various nutritional ingredients such as crude polysaccharide, total phenol, total flavone and the like, have unique flavor, occupy important positions in the food consumption market, but are easily affected by microbial infection, enzymatic browning and oxidation reaction after being picked, so that the color and luster are darkened, the texture is softened, the nutrition is lost and even rotten and spoiled, the shelf life is greatly shortened, and the industrial development of the edible fungi is severely restricted. At present, a single plant essential oil, a chemical preservative or a simple essential oil compound system is commonly used in the field of edible fungus preservation, the single essential oil has the limitations of narrow bacteriostasis spectrum and limited antioxidant capacity, and the chemical preservative possibly has residual risk and is contrary to the requirements of consumers on natural safe foods. Most of the existing plant essential oil fresh-keeping products are directly mixed and used, an effective stabilizing technology is not adopted, so that essential oil is high in volatility, short in action period and difficult to realize long-acting fresh keeping, most of the formulas lack systematic screening and optimization, synergistic effect is not formed, bacteriostasis and antioxidation advantages of different essential oils cannot be fully exerted, and fresh-keeping effects are uneven. Therefore, the research and development of a compound plant essential oil preservation system which is scientific in formula, high in stability, remarkable in preservation effect, safe and nontoxic becomes a key direction for solving the preservation problem of the edible fungi after picking.
