Abstract
The invention discloses a preparation method of a natural food drying agent. The drying agent with high quality is prepared by using bacterial cellulose obtained from microbial fermentation and active carbon nanoparticles as main raw materials, and by hydrophobic modification of lipase. The food drying agent prepared by the method provided in the invention is granular, non-toxic and odorless. The drying agent prepared in the invention has very strong moisture absorption performance, and the weight of water absorbed by the drying agent can reach more than 5 times the weight of the drying agent per se; in addition, the active carbon nanoparticles are wrapped in nanopores of the bacterial celluloses, in combined with the hydrophobic modification of the lipase, so that the prepared drying agent has excellent water holding capability, and can be applied to package of various foods.
Description
Technical field
The invention belongs to drier field, particularly relate to a kind of preparation method of wholefood drier.
Background technology
Food desiccant is at the important protective agent of packaging for foodstuff process; especially to the food with the moisture absorption; the food desiccant of current use with silica gel, montmorillonite and quick lime for raw material be prepared from the majority, have environment unfriendly, eat by mistake and produce the problems such as dangerous.For solving this kind of problem, have the drier of some edible naturals to be developed, as the drier etc. of starch based, but there is the inadequate problem of short texture, moisture pick-up properties and water retention property in these.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of preparation method of natural food drier is provided.
For achieving the above object, the preparation method of the wholefood drier that the present invention relates to, comprises the following steps:
(1) aseptic culture medium is prepared: by weight, take 2-7wt% glucose, 3-8wt% edible alcohol, 1-3wt% dusty yeast, xylan 0.5-2wt%, 0.1-0.4wt% active carbon nanoparticles, excess water be supplemented to 100wt% and be made into culture medium, add bead, after moist heat sterilization, ultrasonic disperse;
(2) concussion fermentation: in culture medium, access metabolism can produce the acetobacter xylinum of bacteria cellulose, 25-30 DEG C of concussion cultivation and fermentation 2-6 days, obtain the inner bacterial cellulose microsphere containing active carbon nanoparticles, take out microballoon, 1h is soaked by the NaOH solution of 0.1M, then repeatedly rinse to neutrality by deionized water, drain surface moisture;
(3) enzymatic: immerse in natural acetic acid ethyl ester by the bacterial cellulose microsphere draining surface moisture, then adds microspheres quality 0.1wt% lipase, in 40-60 DEG C of catalysis 2-4h;
(4) dry: to take out the bacterial cellulose microsphere after enzymatic, repeatedly clean with edible alcohol and water and remain to without ethyl acetate, after drying, obtain granule state food drier.
Wherein, the bead of described bead usable diameter 0.1-0.3cm, addition is often liter of zymotic fluid 10-50.
The concussion speed that described concussion is cultivated is 100-300rpm.
Described drying is the one in vacuum freeze drying, microwave drying.
The food drier that method provided by the invention prepares is graininess, nonpoisonous and tasteless.
The present invention is by controlling composition and the condition of culture of culture medium, control nano aperture and the size of bacteria cellulose, the drier prepared has extremely strong moisture pick-up properties, water absorbing capacity can reach more than 5 times of own wt, meanwhile, active carbon nanoparticles is wrapped in the nano aperture of bacteria cellulose, adds the hydrophobically modified of lipase, make the drier prepared possess outstanding water holding capacity, can be applicable in all kinds of packaged food.
Preparation method of the present invention is absorption carrier with bacteria cellulose, has renewable and degradability, can not cause burden to environment, belongs to environmentally friendly product., reuse after this drier is renewable, regenerative process also there will not be the phenomenon of cracking, constant product quality, and cost is low meanwhile.
