Problems solved by technology

Since the surface of Jinfu mushroom has only a thin and breathable skin structure, the water loss of Jinfu mushroom after harvesting is much higher than that of fruits and vegetables, and the respiratory intensity of Jinfu mushroom after harvesting is 8 times that of common fruits and vegetables at the same temperature. ~20 times, so Jinfu mushrooms are very intolerant to storage. Regardless of using polysaccharide film, protein film, lipid film, or a composite film of the three for preservation, Jinfu mushrooms need to be stored at low temperature and stored on the shelf. The period can basically not exceed 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 Chrysanthemum chrysanthemum in potassium silicate solution with a concentration of 0.1mmol / L for 10 minutes, then apply the film-preserving solution to the film by dipping, and dry to obtain the product.

[0018] The golden blessing mushroom 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 sporocarp of Chrysanthemum chrysanthemum in a sodium silicate solution with a concentration of 0.6mmol / L for 30min, then apply the film-preserving solution to the film by spraying, and dry to obtain the product.

[0022] The golden blessing mushroom after the above treatment can be kept fresh for 10 days under the condition of 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 sporocarp of Chrysanthemum chrysanthemum in a potassium silicate solution with a concentration of 0.2mmol / L for 20min, and then apply the film-preserving solution to the film by coating, and dry to obtain the product. Example 1

[0026] The golden blessing mushroom after the above treatment can be kept fresh for 10 days under the condition of 25°C.

Abstract

The present invention discloses a film coating preservation method of tricholoma lobayense. Firstly, the tricholoma lobayense sporocarps are placed into a silicate solution at a concentration of 0.1-0.6 mmol / L to be soaked for 10-30 min, and then the soaked tricholoma lobayense sporocarps are subjected to conventional film coating preservation. The method combines silicate soaking and conventional film coating, greatly reduces the transpiration of the tricholoma lobayense, delays the water loss of the tricholoma lobayense, can also reduce the aerobic respiration intensity of the tricholoma lobayense to the lowest, but enables no anaerobic respiration of the tricholoma lobayense, reduces the consumption of nutrients, increases the strength of the cell walls of the tricholoma lobayense, and strengthens the resistance ability of the tricholoma lobayense to the outside world, so that the tricholoma lobayense treated through the preservation method provided by the invention can be stored and preserved at room temperature with a preservation period up to 10 d or above.

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 jinfu mushrooms. Background technique [0002] Tricholoma Lobayense Heim (Tricholoma Lobayense Heim), also known as "Lobay Tricholoma", belongs to Basidiomycotina, Phytomycetes, Agaricaceae, Tricholomaceae. The fruiting bodies of Jinfu mushroom are clustered, long and thick, and the meat is crisp and tender. It has a unique taste, excellent flavor and rich nutrition. It is known as the best among mushrooms with excellent taste and quality. Jinfu mushroom is a large-scale high-temperature fungus. The fruiting time is mainly in summer. The conditions for fruiting are harsh, and it is difficult to preserve after harvesting. Freshly picked fruiting bodies of edible fungi have high water content, and are very easy to lose water and be infected by microorganisms, resulting in spoilage and deterioration of fruiting bodies of edible fungi,...
