Method for preparing food-grade glassine paper using mycelium from submerged fermentation of edible fungi and food-grade glassine paper

A method for preparing a food-grade glassine paper using mycelium from submerged fermentation of edible fungi, the edible fungi referring to edible mushrooms, comprising the steps of:

• step 1, preparing alkali-treated mycelium from submerged fermentation of edible fungi using mycelium from submerged fermentation of edible fungi and a sodium hydroxide solution;
• steaming the alkali-treated mycelium from submerged fermentation of edible fungi in a steamer;
• placing the steamed alkali-treated mycelium from submerged fermentation of edible fungi in purified water to obtain an aqueous dispersion of mycelium from submerged fermentation of edible fungi;
• homogenizing the aqueous dispersion of mycelium from submerged fermentation of edible fungi, followed by adding a citric acid solution to obtain a mycelial suspension;
• centrifuging the mycelial suspension and retaining a precipitate;
• performing vacuum filtration on the precipitate to obtain a mycelial filter cake;
• and placing the filter cake in a mold, followed by air-drying to obtain a mycelium base paper for submerged fermentation of edible fungi;
• step 2:
• mixing waxy corn starch with purified water to prepare a starch solution, followed by adding catechin to obtain an antioxidant food gum;
• and coating two sides of the mycelium base paper for submerged fermentation of edible fungi with the antioxidant food gum to obtain a mycelium surface paper for submerged fermentation of edible fungi;
• and
• step 3, performing freeze-drying on the mycelium from submerged fermentation of edible fungi and purified water to obtain mycelium powder from submerged fermentation of edible fungi;
• adding beeswax into the power, followed by emulsification treatment to prepare mycelium Pickering nanoemulsion from submerged fermentation of edible fungi;
• and coating two sides of the mycelium surface paper for submerged fermentation of edible fungi with the prepared mycelium Pickering nanoemulsion from submerged fermentation of edible fungi to obtain a food-grade glassine paper.
