Abstract
The invention discloses a kind of preparation methods of the sunset abelmoschus root bud tea of natural in color, are related to health tea technical field, steps are as follows：Sunset abelmoschus root bud is picked, cleaning, the moon dry；Microwave de-enzyming is carried out to okra bud, it is cooling；Okra bud is put into vitamin c solution and impregnates color protection, is dried；By okra bud at 15~20 DEG C precooling, then liquid nitrogen flash freezer again, takes out, thaws at room temperature, repeats above-mentioned freeze-thaw and operates 1~2 time, and the sunset abelmoschus root bud after defrosting is finally carried out quick-frozen, lyophilization, then microwave drying, packaging to get.For bud form after the present invention is drying without apparent shrinkage, natural in color is non-breakable, and the organoleptic quality of sunset abelmoschus root bud tea obtained is good, nutritional ingredient retains high, there is good health-care efficacy.
Description
Technical field
The present invention relates to a kind of preparation sides of the sunset abelmoschus root bud tea of health tea technical field more particularly to natural in color
Method.
Background technology
Sunset abelmoschus root, alias gumbo, wild lotus, are annual herb Malvaceae gumbo platymiscium.Okra is made the medicinal beginning and is seen
Yu Song《Jiayou Bencao》, Hua Jigen, stem, leaf, son make it is medicinal, flower " it is sweet, cold, sliding, it is nontoxic, cure mainly urine leaching and expedite the emergence of, control all
Malignant sore, pus are not recovered person long, make last Fu i.e. more, be persons particularly liable to develop skin infection's key medicine ".Okra is rich in flavones, chlorogenic acid, polysaccharide, simultaneously
Containing vitamin A, B, C and calcium, zinc and selenium and other trace elements, extraction biological general flavone contains in the flower just put and seed benevolence
Amount shelter has first of plant containing flavones, is tens times of ginkgo and soybean, and VE contents are higher by 3000 times of fresh orange-juice, has high
Health value, therefore, fully developing and using sunset abelmoschus flower resource has great significance.Currently, the preparation of sunset abelmoschus root bud tea
Drying vacuum refrigeration, hot air drying, Microwave Drying etc. are often directly used, but since sunset abelmoschus root petal is relatively thin, fiber content is relatively low
Etc. reasons, there is a problem of it is drying after it is frangible, and color after drying and flower-shape holding are not fine.
Invention content
Technical problems based on background technology, the present invention propose a kind of system of the sunset abelmoschus root bud tea of natural in color
Preparation Method, it is drying after bud form without apparent shrinkage, natural in color is non-breakable, and organoleptic quality is good, nutritional ingredient retains
Height has good health-care efficacy.
A kind of preparation method of the sunset abelmoschus root bud tea of natural in color proposed by the present invention, steps are as follows：
S1, picking：In sunset abelmoschus root full blossom early period, sunset abelmoschus root bud is picked, impurity is removed, cleans up, the moon dries in the air to surface
It is dry；
S2, water-removing：Okra bud after drying in the air to the moon carries out microwave de-enzyming, cooling；
S3, color protection：Okra bud after water-removing is put into vitamin c solution and impregnates color protection, is dried in the air to dry tack free；
S4, drying：By the okra bud after color retention at -15~-20 DEG C precooling, then liquid nitrogen flash freezer again,
It takes out, thaws at room temperature, repeat above-mentioned freeze-thaw and operate 1~2 time, the sunset abelmoschus root bud after defrosting is finally subjected to speed
Freeze, lyophilization, then microwave drying, packaging to get.
Preferably, in S2, microwave de-enzyming power is 700~800W, and fixation time is 60~90s.
Preferably, it in S3, is put into 0.05~0.2% vitamin c solution and impregnates 20~40min of color protection.
Preferably, in S4, okra bud 3~5h of precooling at -15~-20 DEG C, then again liquid nitrogen flash freezer 3~
5min。
Preferably, in S4, the sunset abelmoschus root bud after defrosting is cooled to -35~-40 DEG C into scanning frequency in 50~70min
Freeze, and keeps the temperature 60~80min at this temperature.
Preferably, in S4, lyophilization to moisture content 9~10%, then microwave drying is to moisture content 5~6%.
Preferably, in S4, the power of microwave drying is 800~1000W.
Advantageous effect：The present invention picks bud, general flavone, reduced sugar in bud and other effects early period in sunset abelmoschus root full blossom
The content of ingredient is higher；Using microwave de-enzyming, it can quickly make enzyme-deactivating, nutrient component damages are few, can preferably keep bud
Form and color and luster, and fixation is impregnated using vitamin c solution, further improve the color and luster of the bud after drying；It is risen using freezing
Magnificent drying and microwave drying match, and first drying bu sublimation are used to remove most water in bud so that the nutrition of bud
Ingredient and form are kept well, and organoleptic quality is good, and a small amount of water in bud is removed in conjunction with microwave drying, are heated equal
It is even so that the moisture content inside and outside bud reaches consistent, improves the quality of bud tea, and avoids easily occurring using single microwave drying
Dry excessively to cause sallow etc., and before it is dried by bud elder generation precooling liquid nitrogen flash freezer again, then thaw at RT, repeats cold
Jelly-defrosting operates 1-2 times, enables to the cell in bud first to endure cold and expands recovery of thawing again, so as to improve the soft of bud
Degree, it is not easily broken after dry.For bud form after the present invention is drying without apparent shrinkage, flower-shape is full, natural in color, not fragile
Broken, the organoleptic quality of sunset abelmoschus root bud tea obtained is good, nutritional ingredient retains high, there is good health-care efficacy.
