Description
Technical field
The present invention relates to Edible mushroom processing field, be specifically related to a kind of black fungus processing technology.
Background technology
Edible fungi of china output accounts for 70% of Gross World Product.Edible Fungi has become the agriculture three industries of laying equal stress on plant husbandry, aquaculture, is the important channel of China mountain area or poverty-stricken area peasant programme.Jilin Province's black fungus production history is long, and in recent years, Jilin Province's black fungus industry development was rapid, makes it the another mainstay industry becoming rural economy.
Black fungus, with its special health value, has wide market prospects.At present, black fungus industry is all in the critical period of industrial upgrading from scientific research, production, processing, trade etc.But, Industry Foundation is still aobvious weak, black fungus industry is also in the labor-intensive production stage substantially, production unit mostly is family, the mode of production is manual, the roughing such as black fungus is processed naturally to dry, oven dry are for major way, which results in the black fungus product after processing poor in appearance, process time is longer, the shelf-life of product is shorter simultaneously, and particularly through the summer that high temperature is damp and hot, auricularia auriculajudae product substantially all can go mouldy, damage by worms, cannot promote the overall quality of auricularia auriculajudae, its processing technology haves much room for improvement.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of black fungus processing technology, make described processing technology can the presentation quality of improving product and the shelf-life of whole product, shorten process time.
For realizing above goal of the invention, the invention provides following technical scheme:
A kind of black fungus processing technology, comprising:
Remove impurity and bad auricularia auriculajudae in auricularia auriculajudae, then whole auricularia auriculajudae is evenly sprayed with water, its water content is made to be promoted to 20%-26%, 18h-48h is deposited in sealing, then the microwave treatment being 32.6-70 kilowatt by power makes its moisture be down to less than 18%, finally packs, has packed black fungus processing.
Traditional processing method is all generally got damp again by whole for auricularia auriculajudae sodden bubble, and the present invention is through further investigation, find that the method for moisture regain has a significant impact its final product quality for the use of microwave treatment black fungus, the mode that the present invention uses sprinkling instead for this reason makes water content first be promoted to 20%-26% and needs to carry out encapsulation process a period of time, then utilizing microwave sterilization to reduce auricularia auriculajudae water content to meeting the requirements simultaneously, being generally less than 18% or less than 14%.
Wherein, as preferably, described microwave power is 32.6,37,51.2,60 or 70 kilowatts;
As preferably, described water content is promoted to 21%-23%;
As preferably, the described sealing resting period is 18h-48h, is more preferably 20h-32h; In addition, Sealing period of the present invention suitably can also regulate according to seasonal factor limited range, generally closes 18h-20h in 6-9 month, closes 20-32h in May and October, and other months close 32-48h.
The black fungus finished product be generally processed into, require to reach less than 18%, as preferably, moisture of the present invention is down to less than more than 14% 18%; And as more excellent standard, General Requirements is down to less than 14%, as preferably, moisture of the present invention is down to 10%-14%.
Compared with the product processed according to the black fungus product after processing technology process of the present invention and conventional method, present color uniformity in appearance, glossy, auricle is complete, and size is even, free from admixture, without culture medium, without going mouldy, there is the distinctive smell of auricularia auriculajudae, free from extraneous odour, it is large that water sends out psychrometric ratio, the product then uneven color of conventional method processing, size is uneven, there is impurity, have culture medium, have faint odor; On shelf-life, product of the present invention is under the environmental condition the same with conventional method product, after 9 months, product appearance of the present invention still remains unchanged, and not there is situations such as damaging by worms, rot, but the product of conventional method processing is an auricle surface dirt in appearance then, lackluster, and when surrounding environment is hot and humid, occur damaging by worms, go mouldy, putrefactive phenomenon.
Meanwhile, the present invention also coordinates microwave treatment black fungus to contrast to difference moisture regain mode, and under result is presented at limited range of the present invention and mode, it is all better than other modes in outward appearance with on the shelf-life.In addition, the minimizing more remarkable in conventional method consuming time of the whole processing technology of the present invention, improves working (machining) efficiency.
From above technical scheme, the present invention changes tradition processing method for black fungus, new moisture regain mode is utilized to coordinate microwave technology, under process conditions after optimization, process at outward appearance and high-quality black fungus product progressive all to some extent shorten process time on the shelf-life, improve efficiency and the product quality of black fungus processing.
