Description
Technical field
The present invention relates to a kind of tealeaf residue resource and prepare the preparation method of anticorrosion granule, belong to anticorrosion granule technology of preparing
Field.
Background technology
Food industries plays the most important effect in the development of whole national economy.A lot of experts think, I
The food industry significant progress to be obtained of state, it is necessary to be placed on critical positions improving foodsafety.And improve anti-corrosive fresh-keeping
Technical merit, extensively and reasonably apply preservative, be the important leverage strengthening foodsafety, the development of modern food industry
It is unable to do without escorting of preservative.Therefore, the application of the food preservative development to whole food service industry, or even to state of China
People's expanding economy plays very important effect.But, along with people to the understanding of foodsafety and requirement progressively
Improving, chemical preservative is by severe challenge, and considers for resource and economy, and various countries scientific worker is by plant source
The research and development of food preservative are as focus.
The food preservative of existing preparation is for unsaturated organic acid class, conjugated double bond based on structure, but its water solublity
Poor, and action time is shorter, easy oxidation by air inactivates, and limits its range of application.China's tea resources is the abundantest, and thousand
The Folium Camelliae sinensis that facts have proved in a large number over 100 years has a health-care effect to human body, and containing substantial amounts of tea polyphenols, tea saponin etc. in Folium Camelliae sinensis
Organic substance, can produce inhibitory action to food spoilage effectively, thus recycling tealeaf residue to prepare preservative necessary.
Summary of the invention
The technical problem to be solved: the preservative water solublity for existing preparation is poor, and action time is relatively
Short, the defect of easy oxidation by air inactivation, it is provided that a kind of by the dispersion of discarded tealeaf residue is extracted Organic substance, reconcentration is dried

15min, is prepared into Folium Camelliae sinensis and extracts suspension, then 1:5 in mass ratio, Folium Camelliae sinensis extracts suspension and mixes with ethyl acetate stirring,
Collect extract and be placed in rotary evaporated to dryness at 65～80 DEG C, it is milled and is prepared into tealeaf residue extract powder, standby；
(4) 1:1 in mass ratio, filter cake step (2) prepared mixes with deionized water stirring, ferments at 28～30 DEG C of lower seals
5～7 days, filter subsequently and collect filtering residue, being washed with deionized 3～5 times, being prepared into tealeaf residue fiber, more by weight
Meter, weighs 35～55 parts of stalk fibres, 35～45 parts of deionized waters and 10～20 parts of tealeaf residue fibers respectively and is placed in beaker, stir
After mixing mixing 20～30min, centrifugation 10～15min under 2000～3000r/min, collect supernatant, be prepared into Folium Camelliae sinensis
Pulp water solution coagulant liquid；
(5) 1:5 in mass ratio, mixes tealeaf residue extract powder prepared by step (3) with absolute ethyl alcohol and stirring, then 200
～under 300W, ultrasonic disperse processes 10～15min, is prepared into extract dispersion liquid, the most in mass ratio 1:1, extract is disperseed
Drop adds in the tealeaf residue hydrolytically condensable glue of above-mentioned preparation, is stirred at room temperature mixing and continues to drip hydrolytically condensable glue quality
10% poly-vinyl alcohol solution, continues stirring mixing 25～30min, rotates and be evaporated at standing and defoaming is placed in 65～80 DEG C subsequently
Dry, mill and can be prepared into anticorrosion granule prepared by a kind of tealeaf residue resource.
The application process of the present invention is: 1:5 in mass ratio, is added to deionized water by the anticorrosion granule of above-mentioned preparation,
