Description

Serial sorrow is escaped careless tea beverage and preparation method thereof
Technical field
The invention belongs to food processing technology field, it is related to a series of escaping grass with sorrow as the tea beverage of raw material and its preparation side Method.
Background technique
Sorrow escapes grass as Acanthaceae (Acanthaceae) crocodile mouth flower category crocodile mouth flower Clinacanthus nutans (Burm.F.) The herb of Lindau ranges and turns round sequence flower category, and alias has crocodile mouth flower, turns round sequence flower, green arrow, Sabah snakeweed, soft thorn grass etc..Growth In low altitude area sparse woods or in shrubbery, Malaysia, Indonesia, Thailand and south China are distributed widely in the west and south Such as Guangdong, Guangxi, Yunnan area.In recent years, sorrow is escaped the fashionable Southeast Asian countries of grass, the reason is that the local cancer of Malaysia is suffered from Person has found that edible sorrow grass of escaping has suitable effect to antitumor, this report causes medical scientific research worker concern all over the world, And then a series of researchs are expanded to it.Domestic and foreign scholars escape from sorrow and separate in grass, identify a variety of chemical components, including three Terpene, carbon glycosides flavonoids, sulfur-containing compound, phytosterol, pheophytin class, cerebroside, amino acid, microelement, life Alkaloids and a variety of small molecule compounds etc..
Sorrow blade of grass of escaping often is done vegetables and eaten by the escape people in grass growth area of sorrow, and also useful Fresh leaves juicing is drunk, can Enhance the resistance of body.It can be seen that sorrow escapes careless tealeaves and sorrow is escaped two kinds of products of grass meal in China market, but sorrow is escaped grass drink Product but have no correlative study or product.
Why tea is known as " national drink " of the Chinese nation, reason is tea as traditional beverages known to China resident Physiological activator rich in leaf raw material.Tea is one of three big non-alcohol hobby property beverages of world pop, and correlation produces The market scale of product such as tea beverage also improves year by year.With the transformation of consumption idea and life style, tea beverage disappears as China One of the person's of expense favorite drink category.Statistical data shows that tea-drinking consumption market has accounted for entire beverage consumption market 20% or so share.Under this overall background, develops novel tea beverage and be of great significance and vast market prospect. Tea beverage is the tealeaves that is soaked in water, through adding water, liquid glucose, tart flavour in millet paste made of the techniques such as extracting, filtering, clarification or millet paste Product made of the modulation such as agent, edible essence, fruit juice or Sik (Valley) matter extracting solution.
Although the Quality Control Technology relative maturity in the processing of existing tea beverage, the corresponding ingredient of different raw materials and contain There is some difference for amount, this also allow for sorrow escape the product quality control method of careless drink will not be with tea beverage currently on the market Quality Control Technology is identical, that is to say, that the production key technology of the tea beverage such as existing green tea, black tea, oolong tea can not be straight It scoops out for escaping grass with sorrow as in the beverage exploitation of raw material.
The said goods are a kind of water-soluble extractive (abbreviation low cost vegetable plant water extract) of plant material after all by allotment Etc. the drink that is prepared into of techniques, and the raising of product quality is mainly there are three the technical restriction of aspect in the processing of these drinks, one A is the stability of drink, one be drink color, the other is the flavor problem of drink.

Low cost vegetable plant water extract is a kind of unstable system, is easy to be influenced by oxygen, temperature and soup look is made to change.Shadow The master operation for ringing its variation is extraction and sterilizing, and polyphenol content is higher in low cost vegetable plant water extract, and tea polyphenols are a kind of strong Reducing agent easily occurs non-enzymatic autoxidation and generates coloured o-quinone substance, and also easy further oxygen between o-quinone substance Change, forms brown color substance, to make soup look brown stain, especially under high temperature and alkaline condition, tea polyphenols oxidation rate is accelerated, from And influence the quality of low cost vegetable plant water extract.
Another reason for causing low cost vegetable plant water extract brown stain is due to caused by low cost vegetable plant water extract Determination of Chlorophyll de-magging.Ye Lv Magnesium ion in plain molecule generates the pheophytin of black replaced ammonium ion, thus show color deepen in addition it is brown Become.The de-magging effect of chlorophyll is because when polyphenols oxidation generates o-quinone, and hydrogen ion concentration opposite can increase in solution, Under the action of heat, it may replace the magnesium in the green rope of leaf, to be allowed to form black product.
(3) the smell control problem of drink
Plant material contains a large amount of volatile flavor substance, and the taste of some of them ingredient is not to be popular.? In actual processing, have plenty of and carry out frying using by plant material, reduces bad flavor, increase the side of pleasant flavor substance content Method control.Also some is controlled using certain embedding techniques.
