Abstract
A kind of method of from persimmon, producing persimmon tannin, main processes be with persimmon through cleaning screening, the back ultrasonic wave lixiviate of squeezing the juice, concentrate, drying obtains the Weibull product.The method of producing Weibull provided by the invention is in the production process. and need not high temperature, extract, do not destroy the effective ingredient of facile hydrolysis or oxidation characteristic, reduced energy consumption simultaneously by intensified by ultrasonic wave; Normal pressure extracts, and security is good, and operation is simple, and equipment maintenance is convenient; The intensified by ultrasonic wave extraction can obtain the optimum extraction rate in about 20 minutes.It is that main raw material is produced Weibull that the present invention adopts lower-cost persimmon to replace Turkey-galls, greatly reduces raw materials cost, and overall economic efficiency is remarkable.
Description
Technical field
The present invention relates to a kind of preparation method of persimmon tannin, particularly a kind of method that adopts ultrasonic technology from persimmon, to produce persimmon tannin.
Background technology
Weibull is a kind of important foodstuff additive and medicine intermediate, has a extensive future.To be raw material and main product draw in the tower of South America is that the Weibull produce market demand of raw material production increases year by year in the Turkey-galls of China with main product, because the Turkey-galls cost of material is high, causes Weibull enterprise production cost too high.With the persimmon is the feedstock production Weibull, does not still have the report of suitability for industrialized production.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of method that adopts ultrasonic technology to produce persimmon tannin from persimmon, because the Weibull that the present invention obtains is to be that main raw material obtains with the persimmon, so the called after persimmon tannin.
The object of the present invention is achieved like this: a kind of method of producing persimmon tannin from persimmon may further comprise the steps:
Earlier with prematurity and after the bright persimmon of look blue or green puckery removed the spot of persimmon epidermis through cleaning, broken back was standby;
With the persimmon distilled water immersion after the fragmentation;
Soaked persimmon is put into the ultrasonic extraction jar, is 27000-29000HZ in the control ultrasonic frequency, is to extract 15-25 minute under the 37-39 ℃ of condition in temperature, obtains extracting solution;
To concentrate after the water evaporates in the extracting solution, the concentrated solution force feed obtains persimmon tannin to the spray-drying tower drying.
Ultrasonic frequency is 28000HZ.
Temperature is 38 ℃ in the ultrasonic extraction jar.
The mass ratio of persimmon and distilled water is 1: 1 during with distilled water immersion with the persimmon after the fragmentation.
The method of producing persimmon tannin from persimmon provided by the invention has following beneficial effect:
1. need not high temperature.Extracting less than 40 ℃ of water temperature intensified by ultrasonic wave, no poach high temperature does not destroy the effective ingredient of facile hydrolysis or oxidation characteristic;
2. normal pressure extracts, and security is good, and operation is simple, and equipment maintenance is convenient;
3. extraction efficiency height.Intensified by ultrasonic wave extracts and can obtain the optimum extraction rate in about 20 minutes, extraction time only be water-boiling method 1/3rd or still less.
4. minimizing energy consumption.Because supersound extraction need not heating or Heating temperature is low, extraction time is short, therefore cuts down the consumption of energy greatly.
5. the raw material treatment capacity is big, at double or several times improve, and impurity is few, effective constituent is easy to separate, purify.
6. the extraction process cost is low, and adopting lower-cost persimmon to replace Turkey-galls is that main raw material is produced Weibull, greatly reduces raw materials cost, and overall economic efficiency is remarkable.
