Abstract
The present invention provides a kind of Chinese toon bud freezing preservation technique, it is the following steps are included: (1) chooses raw material and impurity elimination sorts；(2) it impregnates；(3) blanching；(4) cooling；(5) cure process；(6) envelope is drained；(7) quick-frozen forming；(8) constant temperature is cold deposits, and processing technology of the invention is used to carry out quick-freezing fresh-keeping processing to fresh and tender Chinese toon stalk leaf, and the original nutrition of Chinese toon is enable to save from damage；And it is quick-frozen after pack, moisture, fragrance volatilizing are few, carry out constant-temperature preserving under smaller temperature difference environment after quick freezing forming, are able to maintain its original form and nutrition, delicious and crisp mouthfeel, color is light green, and the shelf-life was up to 2 years or more.
Description
Technical field
The present invention relates to a kind of freezing preservation techniques, more particularly to a kind of Chinese toon bud freezing preservation technique.
Background technique
Chinese toon bud is called Chinese toon head, Chinese toon, Chinese toon point, and referred to as " vegetables on tree " are even more " green food ".Annual spring
After Clear and Bright before grain rains, both Chinese toon bud can do various dish to the tender shoots of Chinese toon tree hair.It is not only full of nutrition, and medicine with higher
With value, containing volatile aromatics organic matters such as toonins, can spleen benefiting and stimulating the appetite, increase appetite.Chinese toon has clearing heat and promoting diuresis, diuresis
The effect of removing toxic substances, be assist in the treatment of enteritis, dysentery, urinary system infection contamination good medicine.It contains vitamin E and sex hormone substance,
Energy anti-aging and yang-tonifying nourishing yin effect, have certain curative effect to infertility, therefore have the laudatory title of " gestogen ".Chinese toon contains chinaberry
Element, Volatilized smell can penetrate the epidermis of roundworm, roundworm prevented to be excreted from being attached in intestinal wall.Chinese Toon Leaves thickness bud is tender,
The red side of greenery, like agate, emerald, aromatic flavour is full of nutrition to be much higher than other vegetables, is suitble to various people edible.
The collecting period of Chinese toon is short, fresh and tender perishable, places at normal temperature 2-3 days, either freshness, flavor or quality be all
It will be greatly reduced, almost lost distinctive edible value less than one week.Chinese toon is due to adopting rear respiratory intensity big, fugitive color, easily
Lignifying to storage transport, sale, processes in addition the seasonality of production, region are strong and brings great difficulty, therefore is a kind of
The good quick-frozen technique of Chinese toon bud is most important.
Summary of the invention
Technical problem to be solved by the present invention lies in a kind of Chinese toon bud antistaling process is provided, i.e., a kind of Chinese toon bud freezing is protected
Fresh technique.
The technical problems to be solved by the invention solve above-mentioned technical problem using following technical scheme: a kind of Chinese toon
Bud freezing preservation technique, which is characterized in that includes following steps:
(1) raw material and impurity elimination is chosen to sort: it is raw materials used for the Ching Ming Festival front and back Chinese toon tender shoots of leaf stalk one picked, it is whole
Length is between 12-15cm, and the collecting period 30 days or so, raw material color was red tender, and delicious and crisp is strong fragrant, then will be macroscopic dirty
Object and impurity removal, while rejecting pest and disease damage part, foreign matter or defective products in raw material；
(2) it impregnates: Chinese toon bud being carried out in fermentation vat immersion 1~2 hour, remove the foul of Chinese toon bud surface adhesion, impregnate
Water temperature in pond is 40~50 degrees Celsius；
(3) blanching: by the hot water of the stock dispersion after cleaning to 80~100C, sodium bicarbonate is added in blanching water, makes to float
Scalding water ph value is 7.2-7.5, and blanching water and Chinese toon weight ratio are greater than 3:1, and through stirring 3~90S of blanching, the purpose of blanching is to make
Color is by red greening, and the length of time is depending on the temperature of hot water used: it is hot then short, otherwise extend.If blanching overlong time,
Yellowish leaf stalk can be made to soften, and time too short blanching purpose can not achieve；
(4) cooling: the Chinese toon bud after blanching being stirred to cooling in the cold water of 0~10C, is carried out continuously twice, to thoroughly cool down
After pull out；Cooling purpose is that the raw material after making blanching carries out fixation, if cannot cool down rapidly in time after blanching, leaf stalk will
Turn yellow, perception is poor.Cooling purpose twice be even more be to keep cooling more thorough, when stirring cold purpose be also for enable Chinese toon with
Cold water comes into full contact with, and can cool down rapidly；
(5) cure process: impregnating 1-2 hours in 0.6-1.0% calcium chloride, obtains pretreatment Chinese toon bud；
(6) it drains envelope: pretreatment Chinese toon being rinsed with clear water, then drain away the water pack；
(7) quick-frozen forming: in -40~-30 DEG C of quick-frozen 2~5min after sealing, until raw material shapes in bag；
(8) constant temperature is cold deposits: bagged articles after quick-frozen forming are deposited in -20~-18C constant temperature is cold.
The positive effect of the present invention is: compared with prior art, acquired technological progress is the present invention: Chinese toon obstructs leaf
Whole processing, it is quick-frozen it is preceding carry out nature color protection treatment through blanching and cooling process, only carried out using hot water and cold water, without
The hyperchromic additive for adding any chemical component enables the original nutrition of Chinese toon to save from damage；And quick-frozen after pack, water
Point, fragrance volatilizing it is few, quick freezing forming after constant-temperature preserving is carried out under smaller temperature difference environment, be able to maintain its original form and
Nutrition, delicious and crisp mouthfeel, color is light green, and the shelf-life was up to 2 years or more.Processing technology of the invention is used for fresh and tender Chinese toon
Obstruct leaf and carries out quick-freezing fresh-keeping processing.
Specific embodiment
Technical solution of the present invention is further described in detail With reference to embodiment.
