Embodiment 1

[0038] This embodiment provides a method for modifying black fungus. The specific method is to remove the impurities in the black fungus, soak it in an aqueous solution containing 2.0% soluble starch for 2.0 hours after initial washing, and obtain the foamed black fungus; soak the black fungus Spin dry at 1000rpm / min for 1.0min, gradually raise the temperature to 55°C, dry the black fungus until the water content is 15%, and obtain the dried black fungus; take out the dried black fungus and put it into a pressure vessel to dry Black fungus accounts for 25% of the volume of the pressure vessel. After sealing the vessel, heat it to 120°C, pressurize it to 0.5MPa, then quickly release the pressure to normal pressure, and then dry it at 90°C until the water content is lower than 3%. Black fungus.

Embodiment 2

[0042] This embodiment provides a method for modifying black fungus. The specific method is to remove the impurities in the black fungus, soak it in an aqueous solution containing 3.0% soluble starch for 3.0 hours after initial washing, and obtain the foamed black fungus; soak the black fungus Spin dry at 2000rpm / min for 1.0min, gradually raise the temperature to 50°C, dry the black fungus to a water content of 15%, and obtain the dried black fungus; take out the dried black fungus and put it into a pressure vessel to dry Black fungus accounts for 35% of the volume of the pressure vessel. After sealing the vessel, heat it to 140°C, pressurize it to 0.7MPa, then quickly release the pressure to normal pressure, and then dry it at 80°C until the water content is lower than 3%. Black fungus.

Embodiment 3

[0046] This embodiment provides a method for modifying black fungus. The specific method is to remove the impurities in the black fungus, soak it in an aqueous solution containing 5.0% soluble starch for 6 hours after initial washing, and obtain the soaked black fungus; soak the black fungus in Dry at 5000rpm / min for 0.2min, gradually heat up to 65°C, dry the black fungus until the water content is 20%, and obtain the dried black fungus; take out the dried black fungus and put it into a pressure vessel to make the dried black fungus The fungus accounts for 20% of the volume of the pressure vessel. After sealing the vessel, heat it to 130°C, pressurize it to 0.6MPa, then quickly release the pressure to normal pressure, and then dry it at 90°C until the water content is lower than 3%. Black Fungus.

Abstract

The invention discloses a black fungus modifying method and application, belonging to the technical field of food processing. The method comprises the steps of removing impurities in black fungus; carrying out primary cleaning, then soaking the black fungus subjected to primary cleaning by a soluble starch water solution; drying after spin drying, and taking out the dried black fungus and putting the black fungus into a pressure container; sealing the container, heating, pressurizing, and rapidly releasing the pressure to achieve the normal pressure, thus obtaining the modified black fungus. The black fungus processed by the modifying technology has relatively small and uniform pulverization fineness, the brittleness of the fibers of the modified black fungus is increased, so that the black fungus is easily broken to be easily pulverized. The nutrients are easily digested to be absorbed, the nutrients of the modified black fungus are retained, and the dissolution rate is relatively high. The crude fat of the modified black fungus is increased by 0.4%; and the crude fibers of the modified black fungus are reduced by 2.15%.

Description

technical field [0001] The invention relates to a modification method and application of black fungus, belonging to the technical field of food processing. Background technique [0002] Black fungus is a medicinal and edible fungus with unique nutritional value and health care function. The active substances contained in the polysaccharide, adenosine, melanin and dietary fiber endow the black fungus with blood lipid lowering, antithrombotic, blood circulation, blood clot reduction, radiation resistance, Anti-oxidation, hypoglycemic and anti-tumor and other physiological functions. [0003] Ultrafine powder has the advantage of high bioavailability of nutrients, and has gradually become one of the common methods for healthy product development. Black fungus superfine powder has the disadvantages of bad taste of black fungus, high viscosity, strong hygroscopicity and poor stability. When mixed with water or milk, soybean milk and other liquids, it often has poor fluidity, low...
