Abstract
The invention discloses solid instant tea containing fulvic acid and a preparation method for the solid instant tea. The solid instant tea is prepared by performing digesting, mixing, filtering, concentrating, drying, sterilizing, packaging and the like on the fulvic acid and a tea leaf extracting solution, which serve as main raw materials. According to the solid instant tea containing the fulvic acid, the raw materials are readily available; the preparation method is simple; medicinal effects of the fulvic acid are applied to the solid instant tea; the solid instant tea has unique flavor, tastes sour, sweet, fresh and crisp, has the fragrance of tea and is mellow in taste; furthermore, the solid instant tea also has the health protection functions of reducing the blood pressure and the blood fat, improving the immunity of human body, adjusting the spleen and the stomach of human body, resisting cancers, resisting arteriosclerosis, preventing and treating diabetes, improving microcirculation and the like, can be taken for a long time without any side effect and has an extremely good market development prospect.
Description
Technical field
The present invention relates to a kind of instant solid tea that contains fulvic acid and preparation method thereof, belong to food processing field.
Background technology
Instant tea is a kind of brewed simple and convenient, very soluble Powdered tea, its bath is instant, there is no recrement, especially hardly the harmful heavy metal and pesticide remnant of mercurous, a plumbous class, therefore instant tea take again " pure " be its characteristic, won consumers in general's trust, the overall merit that instant tea has concurrently is lightweight, volume is little, packing is skilful, freight charges are economized, development prospect is fine.
Fulvic acid is that in humic acid, molecular weight is minimum, solubility is the highest, also the strongest part of biologically active, contain active function groups many, utilization easily is absorbed by the body, in recent years, many reports affirmed fulvic acid and sodium salt thereof sobering up, hypoglycemic, anti-inflammatory, antiviral, the remarkable result of regulating the aspects such as immune system, antibiotic, antiulcer, show that it has broad application prospects in fields such as medicine, functional foods, fulvic acid is a kind of natural products, through pharmacological evaluation, prove, without any side effects to human body.
The application of fulvic acid at present; mostly concentrate on agricultural and medical aspect; in the research of field of food seldom; as mono-kind of Chinese invention patent CN101265445A, contain assembled alcoholic drinks of fulvic acid and preparation method thereof; the fulvic acid that comprises 0.05%-0.3% in assembled alcoholic drinks; in view of the biologically active of fulvic acid protection gastric mucosa, the health-care effect of outstanding wine.
The instant tea that the fulvic acid of also not take on present market is made as primary raw material, the medical effect of fulvic acid is fully applied, and the patent of instant tea is a lot, quite a few for the instant tea of health protection and therapeutic action, basically adds Chinese herbal medicine and achieves the goal; Bone instant tea as strong as Six-element, formula is lotus seeds, Chinese yam, zaocys dhumnade, pawpaw, mulberry leaf, calcium carbonate, green tea, be applicable to the elderly because of wind, osteoporosis, soreness and weakness of waist and knees, wind-cold-dampness arthralgia, arthralgia and myalgia, the scapulohumeral periarthritis that cold, wet or calcium deficiency causes, cervical spondylopathy, lumbar muscle strain, the multiple pains such as sciatica, the protrasion of the lumbar intervertebral disci, back extremities joint pain, but there is complicated components in Chinese medicine, the unstable shortcoming of quality.
Summary of the invention
The object of the present invention is to provide a kind of instant solid tea that contains fulvic acid, this component and percentage by weight thereof that contains the instant solid tea of fulvic acid is: fulvic acid 0.5～5.0%, tea extract 70.0～90.0%, citric acid 0.1～1%, L MALIC ACID 0.3～1.6%, natrium citricum 0.5～2.3%, steviol glycoside 0.05～1.0%, D-sodium ascorbate 1.0～5.0%, sweetener 6.0～15.0%, maltodextrin 0.1～6.0%, calgon 1.0～2.0%, described percentage by weight all be take the instant solid tea gross weight that contains fulvic acid and is benchmark, and the percentage by weight sum of all raw materials is 100%.
Described sweetener is the mixture after one or both materials in white granulated sugar, glucose, fruit glucose syrup, polydextrose are mixed by any ratio.
Another object of the present invention is to provide a kind of preparation method who contains the instant solid tea of fulvic acid, concrete steps are as follows:
(1) after in proportion fulvic acid, tea extract being mixed, be heated to fulvic acid and dissolve fully, filter, obtain filtrate A;
(2) in proportion citric acid, L MALIC ACID, natrium citricum, steviol glycoside, D-sodium ascorbate, maltodextrin, calgon, sweetener are mixed, then slowly add in filtrate A, the limit edged stirs, until fully dissolve, filters, and obtains liquor B;
(3) by liquor B at normal temperatures, with the speed of 5000～8000r/min, centrifugal 10～30min, filter, and obtains liquor C;
(4) mass percentage content that liquor C is concentrated into to solid content under vacuum is 10%～50%;
(5) by the concentrate drying obtained in step (4), cross 60～300 purpose sieves, at the temperature of 65～121 ℃, sterilization 10～30min makes finished product.
Tea extract of the present invention lixiviate or ultrasonic-leaching according to a conventional method prepares.
Fulvic acid in the inventive method is that pharmaceutical grade fulvic acid or the fulvic acid that makes with reference to method in patent application 200810233669.X " oxidation and degradation of brown coal is produced the method for humic acid and salt thereof " are (with free of contamination hydrogen peroxide as oxidant, and through purifying, make fulvic acid), commercial refining fulvic acid, after the heavy metal detection does not exceed standard, also can be used.
The present invention contains fulvic acid instant solid tea quality standard:
1, product specification of the present invention: every pouch 1.5g, 20 little packed boxes, pour 1 pouch in cup into while drinking, and brews 3 minutes with the 200ml boiling water, and the active ingredient stripping is namely drinkable;
2, subjective appreciation of the present invention: get 1.5g instant solid tea, brew 3 minutes with the 200ml boiling water, can dissolve fast, standing two minutes, cup end free from admixture, the soup look limpid is bright, and fragrance is pure, have the sweet-smelling of tea and distinctive flavour, smell, free from extraneous odour, mouthfeel is pure;
3, product physical and chemical index testing result of the present invention: soluble property: brew instant, the clarification, do not stay recrement: moisture content≤6%, ash≤12%, Tea Polyphenols >=10%, heavy metal meet the GB11671 requirement;
4, product sanitary index testing result of the present invention: total number of bacteria (CFU/g)≤1000, coliform (MPN/100g)≤30, pathogenic bacteria do not detect, and the Pesticide MRL meets GB 2763 requirements.
