Description
Technical Field
The invention particularly relates to anti-aging, beautifying and weight-losing collagen ecological black tea and a processing method thereof.
Background
The collagen is a natural macromolecular substance, accounts for 30-40% of the total amount of proteins in a human body, and is the protein with the largest content in the human body, wherein the micromolecular collagen is the collagen existing in a small peptide form, the collagen which can be directly absorbed by the human body does not need to be decomposed, the smaller the molecular weight of the collagen is, the higher the absorption rate is, the larger the molecular weight of the collagen is, the more difficultly absorbed by the collagen product is, and the more completely absorbed by the collagen product is, the smaller the molecular weight is, the more 10000da the collagen product is, and the less 3000da the collagen product is basically; the black tea is the tea with the largest international tea yield and sale amount, accounts for about 80% of the total trade amount of the tea in the world, is a big tea drinking country in China, and is developed forward, diversified, convenient and health-care along with the improvement of the living standard and the continuous acceleration of the life rhythm of people, so that the requirements of people on beverages are developed, and people also make related inventions and creations to meet the requirements, for example, the publication date of the Chinese patent CN104798923B is 2018.06.19, and the preparation method of the stomach-invigorating and kidney-tonifying black tea is disclosed.
Disclosure of Invention
The invention aims to provide anti-aging, beautifying and weight-losing collagen ecological black tea and a processing method thereof aiming at the technical defects in the prior art, the processing method is simple, and the prepared collagen ecological black tea has anti-aging, beautifying and weight-losing effects and better application and development prospects.
The invention is realized by the following technical scheme:
an anti-aging, beautifying and weight-losing collagen ecological black tea is characterized by comprising the following raw materials in parts by weight: 2-4 parts of collagen peptide powder: 10-40 parts of tea leaves: 0-10 parts of distilled water.
The anti-aging, beauty-maintaining and weight-losing collagen ecological black tea also comprises the following raw materials in parts by weight: 2 parts of collagen peptide powder: 10 parts of tea leaves: 0 part of distilled water.
The anti-aging, beauty-maintaining and weight-losing collagen ecological black tea also comprises the following raw materials in parts by weight: 4 parts of collagen peptide powder: 40 parts of tea leaves: 10 parts of distilled water.
The anti-aging, beauty-maintaining and weight-losing collagen ecological black tea also comprises the following raw materials in parts by weight: 3 parts of collagen peptide powder: 20 parts of tea leaves: 5 parts of distilled water.
A processing method of anti-aging, beautifying and weight-losing collagen ecological black tea comprises the following steps:
1) picking: the standard of picking tea leaves is one bud and one leaf or two buds and two leaves, and the buds and the leaves are complete and uniform;
2) withering: adopting indoor natural withering or withering in a withering trough or a withering machine for withering or heating withering, uniformly spreading the tea leaves at the temperature of 20-24 ℃, the relative humidity of 60-70%, spreading the tea leaves on a withering curtain or a bamboo sieve for 0.5-0.75kg per square meter, and allowing the withering time to be 8-18 h;
3) rolling: rolling or manually rolling at room temperature of 20-24 deg.C and relative humidity of 85-90% for three times (30-50 min each time) until the tea juice is adhered to the leaf surface and tightly held by hand to prevent the tea juice from dripping;
4) fermentation: mixing collagen peptide powder and distilled water, putting into a sprayer, uniformly spraying onto fresh leaves, placing the tea leaves in a fermentation chamber for fermentation at 25-30 deg.C and relative humidity of 80-100%, wherein the fermentation time is 2.5-5 h;
5) and (3) drying: and (2) feeding the fermented tea leaves into a dryer or a baking cage for drying, wherein the drying is divided into two sections, the first section is at the gross fire temperature of 110-.
Further, the molecular weight of the collagen peptide powder is in the range of 500-3000 da.
Further, the collagen peptide powder is prepared by taking animal collagen as a raw material through an enzymatic method, an acid-base method or a thermal degradation method.
Due to the adoption of the technical scheme, compared with the prior art, the invention has the advantages that:
1. the invention provides a processing method of anti-aging, beautifying and weight-losing collagen ecological black tea, which is simple and suitable for industrial popularization;
2. the anti-aging, beautifying and weight-losing collagen ecological black tea prepared by the invention furthest reserves the original quality characteristics and health-care effect of tea, contains the combination of collagen and black tea, and has the effect of synergistically enhancing oxidation resistance;
3. the anti-aging, beauty-maintaining and weight-reducing collagen ecological black tea prepared by the invention is added with animal collagen on the basis of the endogenous plant protein in the tea, is rich in nutritive value and convenient to drink, is suitable for the high-efficiency and fast-paced life style of modern people, and has better application and development prospects;
4. the tea can obviously inhibit the activity of fatty acid synthetase and improve hyperlipidemia and hypercholesterolemia caused by high-sugar diet, and the collagen is added in the process of making black tea, wherein the collagen does not contain fat-causing factors such as sugar, fat and the like, and has the effects of reducing fat and losing weight to a certain extent, activating the activity of lipase and enhancing the capability of decomposing fat.
The antioxidant mechanism of the invention is as follows:
1. the known compounds separated and identified from tea leaves comprise more than 700 kinds, wherein the known compounds comprise primary metabolites and secondary metabolites, the primary metabolites comprise proteins, saccharides, lipids and the like, the secondary metabolites comprise tea polyphenols, tea triadins, theanine, alkaloids, aromatic substances and the like, the polyphenols in the tea leaves account for 18-36% of the dry weight of the tea leaves, the polyphenols mainly comprise flavanols, flavones, flavonols, anthocyanidins and the like, the catechins serve as one large class of the flavanols and account for 70-80% of the total amount of the polyphenols, and phenolic hydroxyl groups in the catechin structure have hydrogen supply capacity, the o-quinones and the diphenol quinones are generated in the oxidation process, so the natural antioxidant is an ideal natural antioxidant, and the collagen is a known component with antioxidant effect and is combined with catechin to show certain synergistic antioxidant effect.
The main reactions in the tea processing process include tea endogenous enzymatic oxidation reaction and hydrolysis reaction:
1. tea endogenous enzymatic oxidation reaction: tea polyphenol substances including catechin are subjected to oxidative polymerization under the action of polyphenol oxidase to form polyphenol polymers such as thearubigin, theaflavin and the like, the thearubigin is taken as a heterogeneous red or brownish red phenolic substance with great molecular difference, is a strong antioxidant, can help an aged organism to resist biological oxidation, and has more excellent effect than tea polyphenol; theaflavin has antioxidant effect by regulating in vivo biological enzyme system activity, directly eliminating free radical, complexing with metal ion, and preventing oxidation of low density lipoprotein;
2. and (3) hydrolysis reaction: the macromolecular substances and the collagen peptide in the tea leaves are subjected to hydrolysis reaction, and the collagen peptide is subjected to hydrolysis reaction, so that the water solubility of the tea leaves is increased, the tea leaves are easy to dissolve in water, and the tea leaves are easy to directly permeate the intestinal wall to be absorbed by a human body, and have the functions of activating cell functions, improving immunity, inhibiting cancer cells, beautifying, keeping bone health and the like.
