Embodiment 1

[0033] Embodiment 1: Ultrasound combined with concentrated lemon juice to dehydrate and improve the quality of Cordyceps

[0034] Select 300 g of fresh, uniformly colored fruiting bodies of Cordyceps militaris with a diameter of 2 to 3 mm and a length of 5 to 6 cm without mechanical damage and wash them to remove impurities attached to the surface. Weigh 600 g of concentrated lemon juice (Guangzhou Jiahao Food Co., Ltd.), immerse the fruiting body of Cordyceps militaris in the concentrated lemon juice, and perform ultrasonic pretreatment. The ultrasonic frequency is 20kHz, the power is 800W, the treatment time is 10min, and the mass ratio of Cordyceps militaris to concentrated lemon juice is 1:2. The processed fruiting body of Cordyceps militaris was washed and drained, and placed in an ultra-low temperature refrigerator to freeze for 5 hours. After the fruiting body of Cordyceps militaris was completely frozen, the frozen material was subjected to negative pressure pulse spra...

Embodiment 2

[0035] Embodiment 2: Ultrasound combined with concentrated orange juice to dehydrate and improve the quality of Cordyceps

[0036] Select 300 g of fresh, uniformly colored fruiting bodies of Cordyceps militaris with a diameter of 2 to 3 mm and a length of 5 to 6 cm without mechanical damage for cleaning and removal of impurities. Weigh 600 g of concentrated orange juice (Guangzhou Jiahao Food Co., Ltd.), immerse the fruiting body of Cordyceps militaris in the concentrated orange juice, and perform ultrasonic pretreatment. The ultrasonic frequency is 20kHz, the power is 800W, the treatment time is 10min, and the mass ratio of Cordyceps militaris and concentrated orange juice solution is 1:2. The processed fruiting body of Cordyceps militaris was washed and drained, and placed in an ultra-low temperature refrigerator to freeze for 5 hours. After the fruiting body of Cordyceps militaris was completely frozen, the frozen material was subjected to negative pressure pulse spray micr...

Embodiment 3

[0037] Example 3: Ultrasound combined with concentrated strawberry juice to dehydrate and improve the quality of Cordyceps

[0038] Select 300 g of fresh, uniformly colored fruiting bodies of Cordyceps militaris with a diameter of 2 to 3 mm and a length of 5 to 6 cm without mechanical damage for cleaning and removal of impurities. Weigh 600 g of concentrated strawberry juice (Guangzhou Jiahao Food Co., Ltd.), immerse the fruiting body of Cordyceps militaris in the concentrated strawberry juice, and perform ultrasonic pretreatment.

Abstract

The invention discloses a method used for conditioning cordyceps militaris dehydration and quality improvement, and belongs to the technical field of domestic fungus dehydration processing. Accordingto the method, fresh cordyceps militaris is taken as a raw material, and is subjected to material selecting and grading, washing is carried out so as to remove surface impurities; supersonic wave combined concentrated fruit juice pretreatment is adopted for enzyme deactivation-fishiness removing pretreatment of cordyceps militaris, draining is carried out, and the freeze drying is carried out; microwave pulse spraying and vacuum freeze drying technology are combined for drying of freeze dried cordyceps militaris. According to the method, supersonic wave combined concentrated fruit juice technology is adopted for osmosis dehydration pretreatment, and then microwave pulse spraying and vacuum freeze drying technology are combined, so that the original form and active components of cordyceps militaris are maintained effectively, drying time is shortened, and drying efficiency is increased; supersonic wave combined concentrated fruit juice cordyceps militaris pretreatment is adopted, so that material drying time can be shortened obviously, cordyceps militaris earthy smell is removed, cordyceps militaris is provided with fruit juice fragrance, and in rehydration process, no cordyceps militaris browning is caused.

Description

technical field [0001] The invention relates to a method for regulating dehydration of Cordyceps militaris and improving its quality, which is mainly used for drying Cordyceps militaris and belongs to the technical field of dehydration processing of edible fungi. Background technique [0002] Cordyceps militaris, also known as Cordyceps militaris, belongs to the order Hyporacea and the family Ergotaceae. In China, Cordyceps militaris has been used as an edible fungus in diet therapy and traditional Chinese medicine for thousands of years (Xiao Y, Xing G, Rui X, et al. Enhancement of the antioxidant capacity of chickpeas by solid statefermentation with Cordyceps militaris SN-18[J].Journal of Functional Foods,2014,10:210-222.). The edible value and medicinal value of Cordyceps militaris are very similar to those of Cordyceps sinensis, but the output of Cordyceps sinensis is very low and the price is very expensive. Cordyceps militaris can be cultivated artificially. replacem...
