Problems solved by technology

Since the surface of matsutake mushroom has only one layer of thin and air-permeable skin structure, the water loss of matsutake mushroom after harvesting is much higher than that of fruits and vegetables, and the breathing intensity of matsutake mushroom after harvesting is 8 to 20 times that of common fruits and vegetables at the same temperature Therefore, matsutake mushrooms are not resistant to storage. Regardless of using polysaccharide film, protein film, lipid film, or a composite film of the three for preservation, it is necessary to store matsutake mushrooms under low temperature conditions, and the shelf life is basically impossible. more than 10 days

Embodiment 1

[0016] 1) Prepare conventional coating preservation solution: add 3g of starch and 95g of water to fully gelatinize in a water bath at 80°C, then add 1g of beeswax and 2g of whey protein, keep it in a water bath at 80°C for 30 minutes, take it out, and cool it to about 60°C. Homogenize twice with a homogenizer, cool down, and get it.

[0017] 2) Soak the fruiting bodies of Tricholoma matsutake in a potassium silicate solution with a concentration of 0.1 mmol / L for 10 minutes, then apply the film-preserving solution to the film by dipping, and dry to obtain the product.

[0018] The pine mushrooms after the above treatment can be kept fresh for 11 days under the condition of 20°C.

Embodiment 2

[0020] 1) Preparation of conventional coating preservative solution: Add 3g of sodium carboxymethyl cellulose to 95g of water, fully gelatinize in a water bath at 80°C, then add 1g of stearyl alcohol and 2g of soybean protein isolate, keep it in a water bath at 80°C for 30 minutes, take out , cooled to about 60°C, homogenized twice with a homogenizer, cooled, and obtained.

[0021] 2) Soak the matsutake mushroom fruit bodies in a sodium silicate solution with a concentration of 0.6mmol / L for 30 minutes, then apply the film-preserving solution to the film by spraying, and dry to obtain the product.

[0022] The above-mentioned treated matsutake mushrooms can be kept fresh for 10 days at 25°C.

Embodiment 3

[0024] 1) Preparation of conventional coating preservative solution: add 3g of guar gum to 95g of water, fully gelatinize in 80°C water bath, then add 1g of acetyl monoglyceride and 2g of wheat gluten, keep in 80°C water bath for 30min, take out , cooled to about 60°C, homogenized twice with a homogenizer, cooled, and obtained.

[0025] 2) Soak the matsutake mushroom fruit bodies in a potassium silicate solution with a concentration of 0.2mmol / L for 20 minutes, then apply the film-preserving solution to the film by coating, and dry to obtain the product. Example 1

[0026] The above-mentioned treated matsutake mushrooms can be kept fresh for 10 days at 25°C.

Abstract

The invention discloses a coating preservation method for tricholoma matsutake. The method comprises the following steps of soaking tricholoma matsutake sporocarp in 0.1 to 0.6mmol/L silicate solution for 10 to 30min, and then carrying conventional coating preservation. According to the coating preservation method for the tricholoma matsutake provided by the invention, silicate dipping and conventional coating are combined, so that the transpiration of the tricholoma matsutake can be greatly reduced, the water loss of the tricholoma matsutake is delayed, the aerobic respiration intensity of the tricholoma matsutake can also be reduced to the minimum without causing anaerobic respiration, and the consumption of nutritional ingredients is reduced; the intensity of cell walls of the tricholoma matsutake is increased, so that the ability of resisting an external environment is improved, the tricholoma matsutake processed through the preservation method provided by the invention can be preserved under ambient temperature conditions, and the length for preservation can achieve 10d or longer.

Description

technical field [0001] The invention relates to a fresh-keeping method for edible fungi, in particular to a film-coated fresh-keeping method for matsutake mushrooms. Background technique [0002] Tricholoma matsutake (S.Ito&S.Imai) Singer is the scientific name of matsutake. It is a precious fungus. Tricholoma matsutake is a kind of pure natural rare and precious edible fungus, known as "the king of fungi". According to legend, after the Hiroshima atomic bomb attack in August 1945, the only surviving plant was matsutake, which could not be artificially cultivated. It grows in alpine woodlands above 3,500 meters above sea level in the cold temperate zone. It has been recorded in "Jing Shi Zheng Lei Wu Ji Materia Medica" in Song Dynasty. Studies have shown that matsutake is rich in protein, various amino acids, unsaturated fatty acids, nucleic acid derivatives, peptides and other rare elements. Matsutake is collected and eaten from early August to mid-October in autumn. I...
