Description
Technical field
The invention belongs to emblic productions, technical field of drying, and in particular to a kind of emblic freeze-drying process method.
Background technique
Emblic is Euphorbiaceae, Leafflower xylophyta.Also known as emblic tree, Phyllanthus embical fruit, olive, Yunnan olive, phyllanthus emblica,
It hopes fruit, Niu Ganzi, such as draw (Tibetan language), Ma Xiangbang (Dai Nationality's language) name long.Emblic is 304 years Shanxi generations just first recorded in " southern vegetation
Shape ", former translated name claims emblic leafflower fruit, to commonly use heat-clearing and detoxifying drug.Up to 23 meters, 50 centimetres of the diameter of a cross-section of a tree trunk 1.3 meters above the ground；Bark is light brown；Branch tool is vertical thin
Striped, by yellowish-brown pubescence.
Its fruit is rich in vitamin C abundant, edible, can promote the production of body fluid to quench thirst, moistening lung for removing phlegm, controls cough, laryngalgia, solution
Globefish poisoning etc..First food flavor is sour and astringent, be for a good while it is sweet, it is therefore named " emblic ".Tree root and leaf hyoscine, the antipyretic detoxicating of energy, control skin
Inflammation, eczema, rheumatalgia etc..Leaf is dried for pillow materials.Seed oil content 16%, for soap system.Bark, leaf, young fruit can be obtained through refining
Tannin extract.The reddish brown brown of timber, hard, structure is careful, flexible, resistance to water-wet, for farm implements and furniture woods, and is excellent firewood charcoal
Bavin.
It mainly originates in the provinces and regions such as Jiangxi, Fujian, Taiwan, Guangdong, Hainan, Guangxi, Sichuan, Guizhou and Yunnan, is born in sea
Pull out 200-2300 meters of mountainous region sparse woods, shrubbery, wasteland or gully area without shade.Like warm dry hot climate.
In order to effectively transport, save emblic, the emblic of fresh picking is frequently necessary to be dried, and common emblic
Sub- drying means is hot-air seasoning, but bad using emblic degree of drying after heated-air drying, is unable to long-term preservation, and influence
Condition and nutritional ingredient in emblic.
Freeze-drying have keep protein etc. will not it is deactivated a little, but its long processing period, cost is than other
It is dry to want high.
A kind of color that can guarantee when emblic is fresh, taste and nutritional ingredient nutritional ingredient are urgently invented, the production cycle is again
Shorter emblic freeze drying technology scheme solves above-mentioned technical problem.
Summary of the invention
For problem mentioned above, the present invention provides the technical solution of a kind of combination heated-air drying and rapid freeze-drying,
It can guarantee emblic mode of appearance and nutritional ingredient, and can the larger shortening production cycle.
Specific technical solution is: a kind of emblic freeze-drying process method includes the following steps:
1) material sorting, examination: carrying out sense organ examination to the emblic raw material marched into the arena, cannot there is rotten, mouldy emblic, former
Other impurities cannot be contained in material；The residual speed of agriculture is surveyed, and pesticide residue and content of beary metal must be in the range of country allow；
2) cleaning and sterilizing: washing silt in emblic, removal foreign matter and withered and yellow leaf, without visible soil and obvious foreign matter,
It is 500 mg/L that emblic after cleaning, which is put into residual chlorine concentration, pH value: in 5.5~6.5 water, immerses 8 ~ 10min of disinfection, disinfection
The water of emblic cleaning afterwards rinses 5 ~ 8min；
3) shred: feed uniformly shreds the emblic in step 2, is then rinsed 1 time with circulating water；
4) it drains: being statically placed in 10 ~ 15min of draining in natural environment；
5) it spreads disk: the emblic after draining in step 4) is uniformly laid on netted pallet, 5 ~ 8cm of tiling height；
6) hot-air seasoning: the pallet that step 5) fills emblic is put into hot air drying case, 0.15 ~ 0.20m/s of wind speed, hot air drying
The temperature of case dries 1 ~ 1.5h at 30 ~ 35 DEG C.
7) vacuum cooled: under vacuum conditions, emblic is cooled to 6 ~ 8 DEG C to the emblic after air-drying；
8) quick-frozen: it is -60 ~ -75 DEG C that emblic after cooling, which is put into freezing chamber in temperature, quick-frozen 2 ~ 3h；
9) vacuum freeze-drying:
A. lyophilization: the emblic after will be quick-frozen is put into vacuum freeze, is evacuated to 80 ~ 90Pa, freeze-drying temperature
For degree at -80 ~ -85 DEG C, the time is 3 ~ 4h；
B. desorbing and drying: and then being evacuated to 50 ~ 60Pa for vacuum freeze, and freeze temperature is at -60 ~ -70 DEG C, the time
For 3 ~ 5h；
10) it is vacuum-packed.
Further, the pallet mesh diameter in the step 5) paving disk is 0.2 ~ 0.3mm.
Experiments have shown that hot blast temperature, hot wind speed are to influence the principal element of emblic heated-air drying.Hot blast temperature is got over
Height, hot wind speed is bigger, and emblic rate of drying is faster, and drying efficiency is higher；But the rehydration characteristics of dry product are with the raising of temperature
Increase with wind speed reduces instead.
Emblic after cleaning is passed through into the heated-air drying of 0.15 ~ 0.20m/s, temperature at 30 ~ 35 DEG C first, it can be by heat
Fast pulldown is to emblic, the moisture rapid evaporation of the emblic surface layer made, while emblic is with the transmitting of heat, moisture by
Step diffuses to surface, and temperature, wind speed and time appropriate ensure that the organoleptic indicator of emblic does not generate big variation, to remaining
The influences such as sweet sub- nutritional ingredient, protein are smaller, do not lose activity also.
Then it will guarantee that emblic epidermis will not send out wrinkle and be hardened by partially dried treated the emblic cooling of hot wind,
It is quick-frozen to be put into progress vacuum freeze-drying processing in vacuum freeze.
Beneficial effects of the present invention: while guaranteeing emblic quality and nutritional ingredient, by being fitted to emblic
The heated-air drying of degree, is then freeze-dried again, farthest keeps the nutritional ingredient and original shape of emblic, and big
The frozen dried period is shortened greatly, improves frozen dried efficiency, while keeping the quality of emblic after handling no longer hard and becoming
Vegetable pine is obtained, it is easily broken and edible.
