[0028] (1) Preparation of water phase: first add 10 parts of polyvinyl chloride paste resin and 2 parts of water-soluble chitosan to 250 parts of water, fully disperse and let stand for 30 minutes, then heat to 75-80 ° C and mix for 10 minutes, then add 8 parts of polyaluminum chloride and 0.5 parts of polyaspartic acid, continue to heat to reflux state and mix for 10 minutes, the resulting mixture is cooled to -5-0 °C within 5 minutes under ice-salt bath, and at -5-0 °C Insulate and mix for 10 minutes, and finally homogenize the mixture twice at a homogenization temperature of 65-70°C and a homogenization pressure of 20-25MPa to obtain an aqueous phase solution;

[0029](2) Preparation of the oil phase: first heat 65 parts of glycidyl methacrylate and 50 parts of hydroxyethyl methacrylate to 85-90 ° C and mix for 10 minutes, then add 35 parts of divinylbenzene, 25 parts of porogen Agent and 2 parts of initiator, after fully mixing, microwave treatment at microwave frequency 2...

Embodiment 3

[0035] The same batch of fruit juices was evenly mixed and divided into four parts on average, and then decolorized by the resins prepared in Example 1 and Example 2 of the present invention, and commercially available D201 resin and D301 resin, and the decolorization rate and deacidification rate were measured. The results are shown in Table 1:

[0036] Table 1 Resin Decolorization and Deacidification Ability Determination

[0037] project Example 1 Example 2 D201 resin D301 resin Decolorization rate 99.1％ 99.3％ 93.5％ 94.7％ Deacidification rate 95.8％ 96.4％ 90.2％ 91.1％

[0038] As can be seen from Table 1, the resins prepared in Example 1 and Example 2 of the present invention have a decolorization rate of more than 99% and a deacidification rate of more than 95% for fruit juice decolorization and deacidification, which are much higher than the currently commercially available food decolorization D201 Resin and D301 resin, so the decolor...

Abstract

The invention discloses anion exchange resin for decoloring and deacidifying of high-quality juice, and relates to the technical field of resin processing. The anion exchange resin is prepared from the following raw materials in parts by weight: 55 to 65 parts of glycidyl methacrylate, 50 to 55 parts of hydroxyethyl methacrylate, 30 to 40 parts of divinyl benzene, 20 to 30 parts of pore-forming agent, 8 to 12 parts of polyvinyl chloride paste resin, 5 to 9 parts of poly aluminum chloride, 3 to 6 parts of aluminum-magnesium silicate, 3 to 6 parts of microcrystalline cellulose, 2 to 4 parts of water-soluble chitosan, 2 to 4 parts of polyglycerol polyricinoleate, 1 to 2 parts of polymaleic anhydride, 1 to 2 parts of initiator, 0.5 to 1 part of vanillyl butyl ether, 0.5 to 1 part of polyaspartic acid, 0.5 to 1 part of coumarin, 10 to 15 parts of ethanol and 200 to 250 parts of water. The anion exchange resin disclosed by the invention is special for decoloring and deacidifying of juice and is capable of removing pigments, organic acids and amino nitrogen in the juice, the decoloring rate is up to not less than 99 percent, and the deacidifying rate is up to not less than 95 percent, so that the color value and the stability of the juice can be remarkably increased.

Description

[0001] Technical field: [0002] The invention relates to the technical field of resin processing, in particular to an anion exchange resin for high-quality fruit juice decolorization and deacidification. [0003] Background technique: [0004] The decolorization and deacidification process is an important link in the production of fruit juice. By removing the organic acid and amino nitrogen in the fruit juice, the color value and stability of the fruit juice can be improved, thereby improving the taste of the fruit juice. In the prior art, the ion exchange method is commonly used. Fermented organic acids such as citric acid and lactic acid are ionized into hydrogen ions and acid radical ions in water, and anion exchange resins are used for selective adsorption. Polymers, proteins, pigments, etc. in the fermentation broth are non-ionic Impurities and metal ions such as calcium, magnesium, potassium, and sodium are not adsorbed by the resin, but are separated out, washed with wa...
