Description
Technical field
The present invention relates to health food manufacture field, be specifically related to a kind of processing method with base of a fruit freeze-drying matrimony vine.
Background technology
Matrimony vine is traditional rare traditional Chinese medicine, is again a kind of tonic food. In the traditional Chinese medical science, think that the flat taste of matrimony vine property is sweet, there is effect of benefiting shrewd head, moistening lung. And matrimony vine contains the nutritional labelings such as abundant natural Beta-carotene, vitamin C, matrimony vine proteoglycan, betaine, linoleic acid and iron, phosphorus, calcium, there is qi-restoratives to calm the nerves, improving eyesight is dispeled the wind, nourshing kidney moistening lung and protect the effects such as liver is antitumor. But the shelf-life of medlar fresh fruit is extremely of short duration, in preparation process, easily there is again the loss of secondary pollution and nutritional labeling taking the dry dried fruit of lycium barbarum as master of traditional airing system, have a strong impact on the development of matrimony vine industry.
The fast development of freeze drying technology, has solved the problem occurring in airing technical process effectively. Existing freeze-drying matrimony vine technology generally need to be passed through raw material selection, sorting and impurity elimination, once cleaning, dewaxing treatment, secondary cleaning, vacuum freeze drying and packaging and other steps (patent publication No.: CN104543843). Medlar fresh fruit epidermis and base of fruit are destroyed serious but carried out twice common cleaning and dewaxing treatment in this technology implementation process, cause that final products base of fruit comes off, craping deform, had a strong impact on mouthfeel and outward appearance; In addition, in vacuum freeze drying process, utilize the mode freeze-drying medlar fresh fruit that shelf gradient-heated heats up to cause the moisture of final products too high, have a strong impact on its mouthfeel.
Summary of the invention
The present invention relates to a kind of processing method with base of a fruit freeze-drying matrimony vine, its unique distinction is, comprises following methods program:
(1) raw material screening: select scarlet full band base of a fruit medlar fresh fruit, remove impurity and bad fruit;
(2) clean: the impurity on medlar fresh fruit surface and silt are cleaned up by purified water, drain surface moisture;
(3) sterilization: the band base of a fruit medlar fresh fruit ethanolic solution obtaining is carried out to sterilization processing;
(4) vacuum freeze drying: the band base of a fruit medlar fresh fruit obtaining is put into freeze drier, treat that temperature reaches below 40 DEG C, vacuum freeze drying, moisture≤5% of control final products;
(5) damp-prrof packing;
(6) finished product carries out sterilizing with ultraviolet irradiation method.
2. in program (2), use purified water to clean in the mode of atomizing spray by conveyer belt the medlar fresh fruit obtaining. Regulating the scavenging period of the rotating speed control medlar fresh fruit of conveyer belt is 5 ~ 8min. Atomizing spray can reduce the damage of medlar fresh fruit epidermis in cleaning process and coming off of base of fruit to greatest extent, ensures that final products full grains come off without distortion, the complete nothing of base of fruit.
3. in program (3), use ethanolic solution to carry out sterilization in the mode of atomizing spray the medlar fresh fruit obtaining by conveyer belt, wherein the volume fraction of ethanolic solution is 70% ~ 75%. Regulating the sterilizing time of the rotating speed control medlar fresh fruit of conveyer belt is 5 ~ 8min.
In program (4) by the band base of a fruit medlar fresh fruit obtaining evenly, be layered in stainless steel freeze-drying pallet individual layer, put in the drying box of freeze drier, in the time that temperature of charge reaches below-40 DEG C, open vavuum pump, maintaining after 60 ~ 90min, in 30min, be warming up to-20 DEG C, after reaching-20 DEG C, in 30min, be cooled to-40 DEG C, keep, after 90 ~ 120min, dividing plate being carried out to temperature programming
Temperature programming method is:
Do not keep 30 ~ 120min higher than-40 DEG C in temperature;
In 90 ~ 120min, be warming up to-25 DEG C ~-20 DEG C, keep 200 ~ 360min;
In 50 ~ 90min, be warming up to-10 DEG C ~ 0 DEG C, keep 250 ~ 450min
In 60 ~ 160min, be warming up to 15 ~-20 DEG C,
In 60 ~ 160min, be warming up to 25 ~-30 DEG C,
In 30 ~ 80min, be warming up to 40 ~ 45 DEG C, keep 360 ~ 480min.
5. the band base of a fruit freeze-drying matrimony vine obtaining in program (5), at 20 ± 5 DEG C, is packed in the environment of relative humidity≤30%, adds food desiccant in packaging bag.
In program (6) by the packed band base of a fruit freeze-drying matrimony vine obtaining with 2500 ~ 5000 kilorad irradiation 60 ~ 120min to the finished product sterilization that carries out disinfection.
Beneficial effect of the present invention is, has fundamentally solved the problems such as the particle shrinkage, the color and luster that occur in airing technique are gloomy, secondary pollution, nutrient loss, has realized process innovation from many-sides such as taste, health, nutrition. The band base of a fruit freeze-drying matrimony vine lovely luster, the base of fruit that utilize the present invention to process be complete not to come off, full grains without distortion, nutritional labeling without loss.
