Embodiment 1

[0016] Bitter melon extract is prepared by the following methods:

[0017] (1) Remove the seeds of bitter melon, crush it, soak it with 5-15 times the amount of 50-100% ethanol aqueous solution, reflux and extract several times, extract for 1-5 hours each time, filter to obtain the ethanol extract and filter residue, combine the ethanol extract, Stand still for 12-48 hours, filter off the precipitate, and recover the solvent to obtain the crude extract; (2) put the water-soluble crude extract on a macroporous adsorption resin column, elute the sugar with water, elute with 50-100% ethanol aqueous solution, and collect the ethanol The eluent is recovered from the solvent to obtain the extract; (3) the water-soluble extract is extracted with 10 to 20 times the amount of dichloromethane, ethyl acetate, and n-butanol in sequence; the remaining aqueous phase after concentration and extraction is washed with methanol until concentrated The substance can no longer be dissolved to obta...

Embodiment 2

[0019] Lotus leaf extract is prepared by the following methods:

[0020] (1) Take the lotus leaf material, dry, soak with 5-15 times the amount of 50-100% ethanol aqueous solution, and then reflux for extraction several times, each time for 1-5 hours, filter to obtain the ethanol extract and filter residue, combine the ethanol extract, Stand still for 12-48 hours, filter off the precipitate, and recover the solvent to obtain the crude extract; (2) put the water-soluble crude extract on a macroporous adsorption resin column, elute the sugar with water, elute with 50-100% ethanol aqueous solution, and collect the ethanol The eluent is recovered from the solvent to obtain the extract; (3) the water-soluble extract is sequentially extracted with 10 to 20 times the amount of dichloromethane, ethyl acetate, and n-butanol; the solvent is recovered to obtain the dichloromethane part extract, ethyl acetate Ester part extract, n-butanol part extract; combined dichloromethane part extrac...

Embodiment 3

[0022] A method for long-term preservation of Agaricus bisporus, using a preservative to treat fresh Agaricus bisporus, the preservative is composed of the following components in mass fractions: 50% citric acid, sodium bisulfite, 10% bitter melon extract, 10% lotus leaf extract 0.03% phytate, 1% amino acid, 1% vitamin B, 1% niacin, 1% Vc, 0.1% trace elements (iron, copper, zinc, cobalt, manganese, chromium, selenium, iodine, nickel, fluorine , molybdenum, vanadium, tin, silicon, strontium, boron, rubidium, arsenic, etc.), the sum of the mass fractions of each component is 100%.

[0023] The above components are firstly dissolved in water, then dried and packaged. When using, first use a little cold boiled water to make a paste of the antistaling agent to be used, so as not to see dry powder, and then dilute it with sterile water at a ratio of 1.5--2%. During the dilution process, you can use it while stirring. The wooden stick scrapes the paste to the four walls of the conta...

Abstract

The invention discloses a method for preserving agaricus bisporus for long term, which is characterized by employing an antistaling agent for processing the fresh agaricus bisporus, the antistaling agent comprises the following raw materials by mass fraction: 50-70% of citric acid, 15-45% of sodium bisulfite, 5-10% of balsam pear extract product, 5-10% of lotus leaf extract product, 0.025-0.03% of natural color protection agent, 1-5% of water-soluble vitamin and 0.01-0.1% of trace element; wherein sum of mass fraction of the raw materials is 100%. The method can effectively prolong the fresh-keeping period of the agaricus bisporus, reduce the release of ethane, keep the hardness of the agaricus bisporus, delay the decreasing speed of chlorophyll, reduce moisture evaporation, reduce the low temperature damage on the agaricus bisporus, keep the balance of saccharic acid degree, reduce the browning due to scratch and block the harmful mushroom poison to prevent propagation harm, prevent mildew, and increase the luster of the agaricus bisporus.

Description

technical field [0001] The invention belongs to the technical field of food preservation, and in particular relates to a method for long-term preservation of Agaricus bisporus. Background technique [0002] The meat of Agaricus bisporus is fat and tender, and contains more mannose, trehalose and various amino acid substances, so it is delicious and nutritious. It is determined that every 100g of dried mushrooms contains 36-40g of protein, 3.6g of fat, and carbohydrates. 31.2g, 718mg of phosphorus, 188.5mg of iron, 131mg of calcium, 14.2mg of ash, 6g of crude fiber, in addition, it also contains vitamin B1, B2, Vc, niacin, etc., because its nutrition is higher than that of ordinary vegetables, so it has "vegetable meat" known as. [0003] Agaricus bisporus is the most widely cultivated, most productive and most widely consumed edible fungus in the world. In recent years, my country's mushroom cultivation has developed rapidly, and its output and export volume surpassed that...
