Problems solved by technology

[0005] At present, the raw material used for pectin extraction is dried pomace after juicing, so coal ash generated during the drying process will be brought in, and then the cleaning steps of dried pomace will be increased, water consumption and sewage discharge will be increased, and the raw material will be greatly improved. Cost; currently, sodium sulfite or sodium hypochlorite is generally used for decolorization of pectin, which will introduce foreign ions and have a certain impact on the quality of pectin

Embodiment 1

[0023] (1) Preparation of the water phase: first add 6 parts of sodium carboxymethyl starch to 200 parts of water, fully disperse and let stand for 30 minutes, then heat to 75-80 ° C and mix for 10 minutes, then add 6 parts of microcrystalline cellulose and 0.5 Part polyaspartic acid, continue to heat to reflux state and mix for 10min, the resulting mixture is cooled to -5-0°C within 5min under ice-salt bath, and kept at -5-0°C for 10min, and finally the mixture is in Homogenize twice at a homogenization temperature of 65-70°C and a homogenization pressure of 20-25MPa to obtain an aqueous phase solution;

[0024] (2) Preparation of the oil phase: first heat 60 parts of cyclohexyl methacrylate and 45 parts of ethylene glycol dimethacrylate to 85-90 ° C and mix for 10 minutes, then add 30 parts of divinylbenzene, 20 parts The porogen and 2 parts of the initiator are fully mixed, and then microwaved at a microwave frequency of 2450MHz and a power of 700W for 5 minutes, and after ...

Embodiment 2

[0030] (1) Preparation of water phase: first add 8 parts of sodium carboxymethyl starch to 200 parts of water, fully disperse and let stand for 30 minutes, then heat to 75-80°C and mix for 10 minutes, then add 4 parts of microcrystalline cellulose and 0.5 Parts of polyaspartic acid, continue to heat to reflux state and mix for 10min, the resulting mixture is cooled to -5-0°C within 5min under an ice-salt bath, and kept at -5-0°C for 10min, and finally the mixture is in Homogenize twice at a homogenization temperature of 65-70°C and a homogenization pressure of 20-25MPa to obtain an aqueous phase solution;

[0031](2) Preparation of the oil phase: first heat 65 parts of cyclohexyl methacrylate and 40 parts of ethylene glycol dimethacrylate to 85-90 ° C and mix for 10 minutes, then add 40 parts of divinylbenzene, 20 parts The porogen and 2 parts of the initiator are fully mixed, and then microwaved at a microwave frequency of 2450MHz and a power of 700W for 5 minutes, and after ...

Embodiment 3

[0037] The same batch of pomace enzymolysis solution 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 was measured. The results are shown in Table 1:

[0038] Table 1 Resin Decolorization Ability Determination

[0039] project Example 1 Example 2 D201 resin D301 resin Decolorization rate 98.8% 98.5% 90.3% 91.2%

[0040] As can be seen from Table 1, the decolorization rate of the resins prepared in Examples 1 and 2 of the present invention for enzymatic hydrolyzate of pomace reaches more than 98%, which is much higher than the current commercially available food decolorization D201 resin and D301 resin, so this paper The resin prepared by the invention has excellent decolorization ability to the pomace enzymatic hydrolysis solution.

Abstract

Relating to the technical field of resin processing, the invention discloses an enzymatic hydrolysate decolorization resin for natural pectin extraction. The enzymatic hydrolysate decolorization resin is prepared from the following raw materials by weight: 60-65 parts of cyclohexyl methacrylate, 40-45 parts of ethylene glycol dimethacrylate, 30-40 parts of divinyl benzene, 20-30 parts of a pore-forming agent, 5-10 parts of caprylic capric triglyceride, 4-8 parts of sodium carboxymethyl starch, 4-8 parts of microcrystalline cellulose, 3-6 parts of Carbomer 934, 3-6 parts of di-octadecyl dimethyl ammonium chloride, 2-4 parts of magnesium aluminum silicate, 2-4 parts of triallyl cyanurate, 1-2 parts of isopropyl myristate, 1-2 parts of an initiator, 0.5-1 part of polyaspartic acid, 15-20 parts of ethanol, and 200-250 parts of water. The resin prepared according to the invention is specifically used for enzymatic hydrolysate decolorization in a natural pectin extraction process, can effectively remove colored impurities from the enzymatic hydrolysate and coal ash brought in during pomace drying, and can reach a decolorization rate up to more than 98%, thereby significantly improving the color value and purity of the obtained pectin.

Description

[0001] Technical field: [0002] The invention relates to the technical field of resin processing, in particular to an enzymolysis solution decolorization resin for extracting natural pectin. [0003] Background technique: [0004] Pectin is derived from fruit peels such as apples and citrus. It is a green and natural water-soluble dietary fiber. In 1981, the International Federation of Agriculture Organization evaluated it as a food additive with no daily intake limit. It can be widely used in jelly, jam, In fruit juice, yogurt products, soft candy and health food. [0005] At present, the raw material used for pectin extraction is dried pomace after juicing, so coal ash generated during the drying process will be brought in, and then the cleaning steps of dried pomace will be increased, water consumption and sewage discharge will be increased, and the raw material will be greatly improved. Cost: Currently, sodium sulfite or sodium hypochlorite is generally used for decoloriz...
