Abstract
The invention discloses a preparation method of radix puerariae granulated tea. The preparation method comprises the steps that fresh radix puerariae is cleaned, peeled and subjected to color protection with sodium citrate color protection liquid for one hour; the radix puerariae subjected to color protection is sliced before being subjected to centrifuge dripping and then is placed in a drying house to be dried; dried radix puerariae slices are smashed into powder through a traditional Chinese medicine pulverizer and screened to obtain whole radix puerariae powder; water is added to the whole radix puerariae powder, and the whole radix puerariae powder and the water are mixed and stirred to be uniform before being placed in a steamer to be well steamed; the well steamed whole radix puerariae powder is placed in a rotary granulator for granulation; wet granulated radix puerariae particles are placed in a blast drying oven to be baked. Since the whole radix puerariae powder is adopted as the raw material for preparing the granulated tea beverage, nutritional ingredients of the radix puerariae can be well reserved; the color of tea soup of the obtained radix puerariae granulated tea is light brown and bright, the taste is mellow, and product quality is stable. The preparation method provides a novel and effective method for deep processing of the radix puerariae and increasing of the added value of the radix puerariae, and promotes increase of incomes of farmers planting the radix puerariae.
Description
Technical field
The invention belongs to teabag drink deep process technology field, particularly relate to a kind of preparation method of root of kudzu vine granular tea.
Background technology
The root of kudzu vine is the traditional medicine food dual-purpose type plant of the Chinese nation, and to be rich in flavone compound, starch nutrition material, human body institute essential amino acid and trace element etc. are famous, can meet the health-nutrition demand of people to food.The nutriments such as the flavone compound in Pachyrhizua angulatus, essential amino acid and mineral matter, have prevent cardiovascular and cerebrovascular disease, promote that women chest enlarge is improved looks, promote the production of body fluid to quench thirst, the health-care efficacies such as abstinence from alcohol of being amusing, its medical value is remarkable, can carry out health product exploitation, increases value-added content of product.The root of kudzu vine is mainly cut into little square fourth shape or the dehydration of sheet post-drying by the processing and fabricating method of tradition kudzu root tea, or it is obtained to be crushed into powder after drying, wherein block kudzu root tea is unfavorable for the release of effective nutriment in the root of kudzu vine, Powdered kudzu root tea again not aspect bubble drink.There is in the root of kudzu vine flavones of health care and medical value, the nutriments such as amino acid can not fully discharge as human body is utilized, because browning reaction all can occur the fresh root of kudzu vine in process, (root of kudzu vine brown stain is because amino-compound contained in the root of kudzu vine is as protein, amino acid and aldehyde, ketone etc. meet with reduced sugar, brown polymer is generated) through series reaction, root of kudzu vine product colour can be made partially yellow on the one hand, cause color and luster sense organ bad and impact is sold, on the other hand owing to lacking the enzyme that can be hydrolyzed brown stain product in human body alimentary canal, the nutriment such as protein in brown stain product cannot be utilized at all, thus rung the edible of the root of kudzu vine and medical value, solve the browning that the fresh root of kudzu vine produces in process.
Prior art does not all adopt protects look measure accordingly; And well can not retain the nutritional labeling of the root of kudzu vine, unstable product quality; New effective method can not be provided for the added value of the deep processing of the root of kudzu vine, the lifting root of kudzu vine, not there is facilitation for the income increasing the peasant planting root of kudzu vine.
Summary of the invention
The object of the present invention is to provide a kind of preparation method of root of kudzu vine granular tea, be intended to solve the nutritional labeling retaining the root of kudzu vine, constant product quality, for the deep processing of the root of kudzu vine, the added value of the lifting root of kudzu vine provide new effective method, the income increasing the peasant planting root of kudzu vine is had to the problem of facilitation.
The present invention is achieved in that a kind of preparation method of root of kudzu vine granular tea, and step is:
The cleaning of step 1, the fresh root of kudzu vine, peeling, protect look 1 hour with natrium citricum colour protecting liquid;
Step 2, protect look after the root of kudzu vine section after centrifuge dripping, be placed in drying room and dry, temperature controls at 60-80 DEG C;
Gegen tablets medicinal herb grinder after step 3, oven dry is beaten powder, is sieved, and order numerical control, built in 60 ~ 100 orders, obtains kudzuvine root total powder;
Step 4, kudzuvine root total powder add water mixing and stirring, and the ratio of water controls 40 ~ 60%;
The compound of step 5, kudzuvine root total powder and water is placed in steamer and cooks, and steam temperature controls at 100 DEG C, 30 minutes time;
Step 6, cook after kudzuvine root total powder granulation in rotary pelleting machine;
Wet root of kudzu vine particle after step 7, granulation cures in air dry oven, and temperature controls at 120 ~ 150 DEG C, and 0.6 ~ 1 hour time, the moisture control of end product is below 6%.
Another object of the present invention is to provide a kind of root of kudzu vine granular tea, using kudzuvine root total powder as raw material, it is characterized in that, this root of kudzu vine granular tea key component is flavones, pueraria starch; Comprise according to root of kudzu vine granular tea described in mass percent: 1 ~ 2% general flavone, 98 ~ 99% pueraria starches.
The preparation method of root of kudzu vine granular tea provided by the invention, adopt kudzuvine root total powder to prepare granular tea drink as raw material, can retain the nutritional labeling general flavone of the root of kudzu vine preferably, general flavone accounts for 1 ~ 2%, its main component is Puerarin, Dai, daidzin, accounts for more than 60% of general flavone.The root of kudzu vine granular tea that this preparation method obtains is processing the starting stage to raw material through color retention, and final products are light brown particle, without brown stain.Gained root of kudzu vine granular tea millet paste lighter color is brown bright, mellow in taste, constant product quality.The present invention is the deep processing of the root of kudzu vine, the added value of the lifting root of kudzu vine provides new effective method, has facilitation for the income increasing the peasant planting root of kudzu vine.Present invention improves over the preparation technology of root of kudzu vine granular tea, effectively prevent the brown stain of product, better remain the active ingredient of the root of kudzu vine, improve the mouthfeel of product.The tea that the granular tea adopting the present invention to obtain obtains after hot-water soak, has non muddy soup, and tea is shallow brown bright, the feature of mellow in taste.
