Abstract
A method for avoiding moisture absorption, caking, oxidation and color changing of dried wolfberry fruit relates to the field of health food. The method is implemented through the following steps of, firstly, preparing applying medium; secondly preparing coating materials; thirdly, applying the coating materials; fourthly, performing screening and packaging. The method for avoiding moisture absorption, caking, oxidation and color changing of the dried wolfberry fruit has the advantage that coated dried wolfberry fruit products are free from moisture absorption, caking, oxidation and color changing and applicable to long-term storage.
Description
one, technical field
The present invention relates to field of health care food, particularly a kind of method of preventing and treating dried fruit of lycium barbarum moisture absorption caking, oxidation stain.
two, background technology
The dried fruit of lycium barbarum that market is sold all adopts highly basic process medlar fresh fruit to accelerate rate of drying in process of production, the wax on removing medlar fresh fruit surface, accelerates moisture evaporation effusion speed.And after wax removal, while dry run is accelerated, the sugar inside matrimony vine and fruit juice also easily expose, and this just causes the dried fruit of lycium barbarum Product transport of processing behind other places, especially higher at temperature, moist south, when 30 ~ 40 DEG C, dried fruit of lycium barbarum is easy to the moisture absorption, sugar fast softening, the dried fruit of lycium barbarum product moisture absorption is caused to lump, have a strong impact on the quality of dried fruit of lycium barbarum product, be unfavorable for the expansion of selling market, thus constrain developing of wolfberry industry.
At present, the technical method of matrimony vine processing enterprise solution matrimony vine caking, variable color is mainly: add sodium sulfite coating method.Sodium sulfite is one of material that in food additives, acute toxicity is stronger, can be carcinogenic, take in heavy dose of sodium sulfite, hemoglobin can be made to become ferrihemoglobin and lose oxygen carrying capacity, cause bodily tissue anoxic, until dead, simultaneously coating method mostly in the past is spraying, evenly be sprayed onto on dried fruit of lycium barbarum in coating drum after coating material is heated, but this method is difficult to coating material spray to shine in the fold of dried fruit of lycium barbarum, the consumption of coating material is also comparatively large simultaneously, and cost is higher.
three, summary of the invention
A kind of method of preventing and treating dried fruit of lycium barbarum moisture absorption caking, oxidation stain is the invention provides for the problems referred to above, it is completed by following steps: the first step: applying medium is got the raw materials ready, applying medium is cleaned up, drain well, the applying medium that particle diameter is 2 ~ 3mm is got in screening, put into rotary mixer, and in rotary mixer, applying medium is heated to 75 ~ 85 DEG C, for subsequent use, applying medium is metallic particles or ceramic particle or stone or its any mixture of two or three, and particle size is 2 ~ 3mm;
Second step: coating material is got the raw materials ready, by coating material, be heated to 75 ~ 85 DEG C, spread upon on first step applying medium for subsequent use, the applying medium being coated with coating material is cooled to 40 ~ 50 DEG C, for subsequent use, coating material is: any one in sucrose ester or glyceryl monoacetate or rice bran wax or palm oil wax or 44 degree of palm oils or 51 degree of palm oils;
3rd step: smear coating material, raw material dried fruit of lycium barbarum is put into rotary mixer and the applying medium mix and blend being coated with coating material, temperature during stirring in cylinder remains on 40 ~ 50 DEG C, and stir 30 ~ 60min, coating material is 0.5% ~ 2% of the quality of matrimony vine;
4th step: screening: sieving being coated with the matrimony vine mixture wiping coating material in the 3rd step rotary mixer, applying medium being sifted out, obtains dressing dried fruit of lycium barbarum finished product.
four, beneficial effect of the present invention is:
After dressing, dried fruit of lycium barbarum product is nonhygroscopic does not lump, and not oxidation stain, is convenient to long term storage.
five, detailed description of the invention
