Abstract

The invention discloses a method for preserving agaricus bisporus by combining vacuum pre-cooling and high-pressure carbon dioxide treatment. The method comprises the following steps that ethanol fumigation is carried out on the agaricus bisporus, and then vacuum pre-cooling is carried out so as to obtain pretreated agaricus bisporus; potato starch, cassava starch, nano silicon dioxide, Tween-60,calcium chloride, a composite traditional Chinese medicine ethanol extract, coptidis rhizoma alkaloid, plant essential oil, Chinese yam polysaccharide, lentinan iron, epsilon-polylysine, nisin, beta-aminobutyric acid, a zinc complex and allyl isothiocyanate and water are uniformly mixed, are subjected to gelatinization and then microwave treatment and are cooled so as to obtain a compound preservative film solution; and the compound preservative film solution is sprayed onto the surface of the pretreated agaricus bisporus, and after drying is carried out, high-pressure carbon dioxide treatmentis carried out. The method for preserving the agaricus bisporus by combining vacuum pre-cooling and high-pressure carbon dioxide treatment has the advantages that the moisture and the color and luster of the agaricus bisporus can be well maintained, and the preservation period of the agaricus bisporus can be prolonged to be 16 days or above.

Description

technical field [0001] The invention relates to the technical field of mushrooms, in particular to a method for preserving freshness of Agaricus bisporus combined with vacuum precooling and high-pressure carbon dioxide. Background technique [0002] Agaricus bisporus is rich in phenols, ascorbic acid, protein, polysaccharides, dietary fiber and other nutrients, and is favored by consumers. However, Agaricus bisporus has high water content, tender tissue, no protective structure on the surface, and severe respiration and transpiration, resulting in weak storability. Under normal temperature, dehydration shrinkage, browning, and hair loss will occur within 1-3 days after harvesting. stickiness etc. Therefore, solving the fresh-keeping problem of Agaricus bisporus after harvesting and prolonging its transportation and marketing period are the only way for the industrial development of Agaricus bisporus. Although various fresh-keeping technologies such as modified atmosphere p...
