Production Techniques and Processing Methods for Mushroom Beverages
1. Ingredients
420 g of cull mushrooms or dried mushroom stems, 150 g of milk powder, 160 g of white sugar, 50 g of glucose, 46 g of citric acid, 2 g of sorbic acid, 0.5 g of the food colouring carmine, 2 mL of food flavouring, and 10 L of purified water.
2. Preparation
(1) Wash the cull mushrooms and mushroom stems from the mushroom production and processing stages in a 0.05% sodium sulfite solution to remove mud, sand and impurities, then remove them. Soak them in a 0.1% sodium sulfite solution to preserve colour, then rinse with water, and then sun-dry or oven-dry for later use.
(2) Pour the above cull mushrooms or mushroom stems into an aluminium pot, add 3 L of purified water, boil for 30 minutes, filter through multiple layers of gauze, collect the filtrate, add water to bring the volume back up to 3 L, then add the glucose, white sugar and milk powder, mix evenly with the filtrate, and filter to obtain the stock solution.
(3) First wash all containers with water, then disinfect them with a 0.2% potassium permanganate solution or a 0.3% bleaching powder solution, and finally rinse them with purified water for later use.
(4) Pour 1 L of purified water into a disinfected container, then add the citric acid, sorbic acid, flavouring, colouring and so on. After they dissolve, pour in the stock solution, mix evenly, and it is ready to be bottled.
(5) Fill each bottle so that the liquid level is 0.5-0.6 cm below the bottle mouth, and seal the cap while hot. Sterilise at 100°C for 20 minutes, and store in the warehouse after cooling.
If corn and mushrooms are added together, a corn-mushroom beverage can be made. The method is as follows:
(1) Wash the corn and corn silks. Soak the corn in alkaline water for 3-5 hours, remove and drain, put into a pot, and stir-fry over high heat until it puffs. Cut the corn silks into 1-1.5 cm lengths, put them into the pot, and bake briefly.
(2) Crush the stir-fried corn kernels so that each kernel is broken into 8-14 pieces.
(3) Take the mushroom powder and mix it with the above two ingredients, and it can be taken by mixing with boiling water.
