Description
Technical Field
The invention relates to the technical field of resin exchange, in particular to a method for removing protein precipitates in yellow wine by utilizing polysaccharide ion exchange resin.
Background
The yellow wine is a special national product and a traditional food in China, and has the advantages of rich nutrition, mellow wine taste, benefit for body health and the like. One of the most prominent problems in the yellow wine industry has been the appearance of turbidity and precipitation during shelf life. The yellow wine has complex non-biological precipitation condition and more influence factors, and researches show that the content of protein in the precipitate of the yellow wine is more than 10 percent, and the yellow wine precipitation is generally thought to be mainly caused by the combination of the protein and coexisting substances (such as polysaccharide, polyphenol, metal ions, dissolved oxygen and the like), so the protein is a main factor causing the turbidity of the yellow wine and the precipitation. The problem that yellow wine precipitation is a hot concern about product quality and enterprise development is solved, and corresponding technical innovation is very necessary.
At present, yellow wine production enterprises often adopt a freezing treatment method and a clarifying agent method to remove abundant protein in raw wine so as to achieve the aim of removing precipitates. The freezing treatment method is to reduce the temperature of the yellow wine in a short time to precipitate unstable substances in the wine liquid, so as to achieve the aim of removing the precipitate. Compared with the prior art, the method for removing yellow wine precipitate by using various clarifiers in the market is a method commonly adopted by enterprises, the commonly used clarifiers comprise tannin, silica gel, bentonite, PVPP, sodium alginate and the like, but the clarifiers are easily affected by the dosage of the clarifiers, pH, wine body components and other factors, and the problem of yellow wine precipitate cannot be effectively solved. The protein precipitate is removed, but the water-soluble and alcohol-soluble proteins are not removed, and the proteins are easily denatured and continuously precipitate during the storage period and the shelf life under the influence of external conditions, so that the quality control of the yellow wine is difficult. The method adopts a plurality of removal processes, and firstly, the method based on the adsorption principle (without selectivity) is difficult to completely remove protein; secondly, the cost is increased dramatically, and enterprises are hard to bear. Therefore, the method for effectively removing the protein precipitate in the yellow wine is of great significance.
At present, the ion exchange technology separation has the advantages of high separation efficiency, short time, high sensitivity, good reproducibility, large adsorption capacity, high recovery rate, elution under mild conditions, no protein denaturation or enzyme inactivation and the like. The technology for separating protein by ion exchange technology is mature, but the application of the technology in the field of yellow wine is still blank.

When the number of the adsorption columns is more than 2, one of macroporous ion exchange resin and gel resin is arranged in the middle adsorption column, which is favorable for further adsorption of protein precipitate.
Preferably, the adsorption column provided with the macroporous ion exchange resin is externally provided with a heat insulation sleeve, the heat insulation sleeve is a temperature control jacket, hot water is introduced into the interlayer from a hot water controller to control the temperature, and the operation is convenient. The yellow wine contains trace organic compounds such as methanol, aldehyde and ether, has certain influence on human bodies, and because the boiling point of the organic compounds such as aldehyde and ether is low and is generally about 20-35 ℃, in order to reduce the residual quantity of the organic compounds as much as possible, the yellow wine is heated to volatilize the trace organic compounds contained in the yellow wine along with the temperature rise, and the trace organic compounds are volatilized along with the outflow of wine from the wall of a reticular column in the last adsorption column.
The suction filtration pump is arranged below the adsorption column of the macroporous ion exchange resin, so that the adsorption column is prevented from being blocked due to long-time use.
Preferably, the outlet at the lower end of the adsorption column is communicated with the inlet at the upper end of the adsorption column at the back through a liquid guide pipe. The shaking table device is arranged below the first and the middle adsorption columns, which is beneficial to the rapid adsorption of the adsorption columns.

The ion exchange resin taking polysaccharide as a matrix has a hydrophilic network structure skeleton, and can effectively adsorb protein in yellow wine without denaturation. After the yellow wine is treated by the method, the light transmittance of the yellow wine is obviously improved, and the wine body can still keep good stability in the shelf life. The resin with saturated adsorption can be repeatedly used after elution and regeneration, and the eluted protein can be used as other byproducts such as feed and the like after processing, so that the production cost is greatly reduced.

Preparation example 1: macroporous ion exchange resin pretreatment process
Soaking for 24h by using ethanol with the concentration of more than 95 percent of volume concentration → washing by using ethanol until the effluent liquid is not turbid with water in a ratio of 1: 5 → washing by using water until no alcohol smell exists → passing 5 percent of HCl with mass concentration through a resin column, soaking for 2-4h → washing by using water until the effluent liquid is neutral → passing 2 percent of NaOH with mass concentration through the resin column, soaking for 2-4h → washing by using water until the effluent liquid is neutral for standby.
Preparation example 2: gel resin pretreatment
Pretreatment of the cationic gel resin: the resin is first washed (preferably backwashed) with clear water until the effluent is clear, haze-free and contaminant-free. And then, alternately soaking the resin in 4-5% HCl and NaOH in the exchange column for 2-4 hours in sequence, leaching the resin between acid and alkali by using a large amount of clear water (preferably leaching the resin by using a mixed bed of high-purity deionized water) until the effluent is nearly neutral, and repeating the above steps for 2-3 times, wherein the dosage of the acid and alkali is 2 times of the volume of the resin each time. The final treatment is carried out by using 4-5% HCl solution, and the doubling effect of the dosage is better. The acid liquor is completely discharged, and the acid liquor is leached to be neutral by clear water and then is filled into the adsorption column.
