Abstract
The method for producing oolong tea beverage includes such technological steps as preparing extracted liquid oolong tea, concentration, dilution using filtered deionized water, overflow packaged, pasteurizing and storage, and features good taste, simple production apparatus, high productivity and pure natural product.
Description
The present invention relates to a kind of is the manufacture method of raw material, limpid, tea beverage with long preservation period with the oolong.
Common canned oolong tea is with after filtration of tea extract process or the centrifugalization, is heat sealed in the container, makes (Japanese Patent is openly speciallyyed permit communique, flat 1-202247) through 110-125 ℃ of pressure sterilizers, sterilization in 15-30 minutes again.Because sterilizing time is long, the quality of tea can be because of long-time high temperature variation, and production efficiency is also lower.In addition, produce muddy and precipitation in order to prevent and to reduce tea beverage in depositing, the employing enzyme decomposition method that has is (as Chinese invention patent: application number 87103320A; Japanese Patent: openly specially permit communique, flat 3-280832), the adding calcified material that has (as Japanese Patent: openly specially permit communique, flat 3-290151) etc. is handled; In order to prevent the tea beverage oxidation deterioration, to add different-ascorbic acid or different-sodium ascorbate sometimes, when canned, to charge into air in the nitrogen replacement jar (as Japanese Patent, openly specially permit communique, flat 1-240145), the equipment complexity, technical requirements is also than higher.After adding ascorbic acid, under high temperature action, tend to make millet paste to produce a kind of peculiar smell, and be difficult for eliminating fully; Fill nitrogen and handle, not high as nitrogen gas purity, can accelerate the oxidation deterioration of tea beverage on the contrary.
The purpose of this invention is to provide a kind of production method of producing limpid good to eat, oolong tea beverage with long preservation period with easier device.
The present invention is achieved in that
1. press well-established law, earlier oolong is ground, the deionized water with heating extracts again, makes the extract of water soluble tea composition; 2. handle prepared extract with nanofiltration,, obtain full-refined strong tea juice high molecular weight composition and bacterium filterings such as protein; 3. use nanofiltration, filter particulate, germ and the bacterium in the ionized water after, again with full encapsulation behind the proper proportion dilution extract; 4. the tea beverage after will encapsulating is stored after with pasteuring.
Advantage of the present invention is: 1. do not add antioxidant, improve taste; 2. need not fill nitrogen, simplify equipment; 3. without pressure sterilizer, enhance productivity, improve taste; 4. without cemical additives such as enzyme and calcified materials, be pure natural beverage.
Effect of the present invention is expressed with table 11.
Table 1 is the comprehensive comparison of sample A, B, C.
Table 2 is flavor evaluations of sample A and preserves test.
Table 3 is sample A health and physico-chemical analysis result.
Below in conjunction with the description of embodiments of the invention and comparative example, further provide ins and outs of the present invention.
(A) embodiment 1, and one kilogram oolong is pulverized, and is sub-packed in 8 140 purpose stainless steel cloths, with the extraction 15 minutes under constantly stirring of 15 liters 95 ℃ deionized waters, makes water soluble tea composition extract.Extract again through the NF membrane nanofiltration of the mol wt 20,000 that dams, obtains full-refined strong tea juice after two-layer 200 order stainless steel cloth pre-filterings.Afterwards, with through the mol wt that dams being deionized water after 20,000 the film nanofiltration, with dilution proportion tinning in 1: 3.The three-chip type that present embodiment uses 250 milliliters of nominals is dress type pop can completely, and it is filled (about 280 milliliters), the mat overflow jar interior air of draining, realize full tinning, at last, the tea beverage after the sealed cans 95 ℃ of following pasteurizes 5 minutes, is cooled to room temperature storage (sample A).Present embodiment also can adopt bottled full encapsulation.
(B) comparative example 1, with (A), only adorns 250 milliliters when being tinning, stays about 30 milliliters space (sample B).
(C) comparative example 2, and is surplus with (A), is to be added with 125ppm ascorbic acid (sample C) in the last tea beverage.
Find out that from table 1-3 situation the oolong tea that the inventive method is produced is limpid good to eat, quality is good.Product is also through the expert statement of Shanghai City tealeaves association, thinks limpid fragrance, and pure taste can satisfy the beverage market needs.
