Embodiment 1

[0022] Vigorous growth, plump, non-polluting parent species of Sagittarius are selected, and the weight percentages of the medium material and its dosage are: 8% maltose, 2% corn flour, 2% wheat bran, MgSO 4 0.3%, KH 2 PO 4 0.2%, ZnSO 4 1.0%, VB 1 0.1%, α-naphthaleneacetic acid (NAA) 1.5mg / L, p-chlorophenoxyacetic acid (4-CPA) 9.5mg / L, and the balance is water, in the above-mentioned medium, insert the parent species of Sagittarius, Cultivate on a shaking table at 23°C for 14 days, take mycelium and dry it in an oven at 60°C and crush it. Soak the obtained mycelia of S. sativarii first with water of the same weight, then pre-treat with 220w ultrasonic waves for 20 minutes, and then replenish water to the weight ratio of material to liquid of 1 : 20, then put into the extraction tank, heat up to 60°C, adjust the pH value to 5, add 0.5% cellulase by weight of the extract, react enzymatically for 30min, then add papaya with 2% weight of the extract For protease, after en...

Embodiment 2

[0024] Vigorous growth, plump, non-polluting parent species of Sagittarius sagittarius is selected, and the weight percentages of the medium material and its dosage are: 6% maltose, 1% corn flour, 3% wheat bran, MgSO 4 0.15%, KH 2 PO 4 0.1%, ZnSO 4 1.4%, VB 1 0.05%, α-naphthaleneacetic acid (NAA) 9mg / L, p-chlorophenoxyacetic acid (4-CPA) 1.5mg / L, and the balance is water, in the above-mentioned culture medium, insert the Sagittarius parent species, in Cultivate on a shaking table at 23°C for 8 days, take the mycelia, dry them in an oven at 60°C, and then pulverize them. After soaking the obtained Mycelia of Scutellaria Scutellaria with the same weight of water, pre-treat with 80w ultrasonic wave for 40 minutes, and then replenish the treated Mycelium of Scutellaria Scutellaria until the weight ratio of material to liquid is 1 : 30, then put into the extraction tank, heat up to 60°C, adjust the pH value to 5.5, add 1% cellulase by weight of the extract, react enzymatica...

Embodiment 3

[0026] Vigorous growth, plump, non-polluting parent species of Sagittarius sagittarius is selected, and the weight percentages of the medium material and its dosage are: 3.5% of maltose, 3% of corn flour, 5% of wheat bran, MgSO 4 0.06%, KH 2 PO 4 0.07%, ZnSO 4 0.7%, VB 10.02%, α-naphthaleneacetic acid (NAA) 5mg / L, p-chlorophenoxyacetic acid (4-CPA) 5.5mg / L, and the balance is water, in the above-mentioned culture medium, insert the parent species of Tiger palm, in Cultivate on a shaking table at 23°C for 11 days, take the mycelium, dry it in an oven at 60°C, and then pulverize it. Soak the obtained mycelia of S. sativarii first with water of the same weight, then pre-treat with 420w ultrasonic waves for 30 minutes, and then replenish the treated mycelium of S. : 40, then put into the extraction tank, heat up to 45°C, adjust the pH value to 5.5, add 2% cellulase by weight of the extract, react enzymatically for 60min, then add papaya with 0.5% by weight of the extract F...

Abstract

The invention provides a tremellodon gelatinosum mycelium preservative and a preparation method thereof. The production technology procedure is as follows: drying the tremellodon gelatinosum mycelium, smashing, ultrasonically processing, processing by means of enzymolysis and filtering to obtain the extracting solution of the tremellodon gelatinosum mycelium; and allocating with agar, carboxymethyl chitosan, citric acid and sodium citrate to obtain the tremellodon gelatinosum mycelium preservative. The tremellodon gelatinosum mycelium preservative prepared by the method is a natural food preservative which is mainly used for the coating preservation of high-quality wild edible mushrooms such as tricholoma matsutake, toadstool and termite mushroom, etc. The invention can prolong the preservation time at 6-9 days, thereby being capable of reducing the deterioration degree when storing and transferring the high-quality wild edible mushrooms and improving the commodity value.

Description

technical field [0001] The invention relates to the technical field of food preservation, in particular to a antistaling agent for mycelium of Sagittarius tiger palm and a preparation method thereof. Background technique [0002] Pseudohydnum gelatinosum is a basidiocarp soft and gelatinous, and is a rare and valuable wild edible fungus. According to the analysis and determination, the fungus is rich in polysaccharide, protein, fat, carbohydrate, crude fiber, phosphorus, iron, calcium, riboflavin, carotene, 17 kinds of amino acids and trace elements, and also contains ergosterol which is lacking in ordinary vegetables And a relatively complete range of vitamins. Tiger palm fungus is flat and sweet in nature, has the effect of chasing wind and cold, lowering cholesterol, relaxing tendons and activating blood, nourishing qi, treating wind and breaking blood, harmonizing stomach and laxative, lowering blood pressure, detoxifying food, curing Effects such as headache and dizzi...
