preparation example Construction

[0028] The preparation method of the fast-food white fungus is as follows: (1) the raw white fungus is cleaned and then cured; (2) the cured white fungus is subjected to microwave vacuum freeze-drying to obtain the final product.

[0029] The ripening mentioned therein can be ripened by microwave or heating in a reaction tank.

[0030] The heating and aging in the reaction tank can be performed at a reaction pressure of 0.4-0.8 MPa and a temperature of 100-200° C. for 20-60 minutes. It can also be aged at 100-150°C under normal pressure for 60-120 minutes.

[0031] Wherein, in order to obtain uniform white fungus leaves, the white fungus can be trimmed and screened. The white fungus can be cut whole, or after ripening.

[0032] The microwave vacuum freeze-drying described in the above step (2) refers to drying using microwave vacuum freeze-drying equipment. The temperature is 0 to -50°C, preferably -10°C to -30°C. The degree of vacuum is usually maintained at 13-300Pa, pre...

[0037] Wherein, the comparative example is prepared according to the method of the inventor's previous work, ZL 02113746.3.

[0038] The rehydration time is determined by the following method: take 2g of the sample and put it in a heat preservation container with a cover, add 300ml of water above 85°C, and start timing with a stopwatch at the same time. Clamp the white fungus with a glass piece, observe the pasting state and record the time when there is no obvious hard core, which is the rehydration time.

[0039] In summary, the fast food dried white fungus prepared by the method of the present invention has the original shape of the white fungus before rehydration, and the rehydration time is short, convenient and quick, providing a new option for the fast food field.

Abstract

The invention relates to a snack dry tremella and a preparation method thereof, belonging to the technical filed of snack food, and providing a novel snack dry tremella on the basis of the preliminary work. The water content of the snack dry tremella is 3-5%; before rehydration, the snack dry tremella keeps the original shape of tremella leaves, the shape and volume thereof are the same as the raw tremella or the tremella before being dried; and the section thereof is cellular, the volume after the rehydration increases by 5-20%, but the shape does not change basically. The rehydration time is very short and does not exceed 5min, and the tremella can be rehydrated within 1min at the fastest speed. In the preparation process, no useful elements are lost, and the shape and the flavor of theoriginal tremella are reminded. The tremella can be soaked with boiling water for eating during traveling and going out, and is delicious as the boiled tremella porridge after being added with medlar, red jujube, crystal sugar and the like,.

Description

technical field [0001] The invention relates to a fast food dried white fungus and a preparation method thereof, belonging to the technical field of fast food. Background technique [0002] Tremella contains protein, fat, carbohydrates, crude fiber, inorganic salts, vitamins and a variety of amino acids, has anti-aging, anti-tumor, anti-radiation, anti-inflammatory, and promotes the synthesis of proteins and nucleic acids. Regular consumption of white fungus is good for your health. Chinese Pharmacopoeia records: Tremella has the effects of nourishing and strengthening, strengthening the body, nourishing yin and moistening the lungs, and benefiting the spleen and kidney. Tremella has high medicinal and edible value, and is known as "mountain delicacy" by people. [0003] But the traditional cooking method needs to spend a lot of time, and the white fungus that boils is also inconvenient to carry, has greatly influenced people's edible white fungus. For the modern fast-pac...
