Embodiment 1

[0022] (1) Preparation of water phase: first add 10 parts of polyethylene oxide and 2 parts of propylene glycol alginate to 250 parts of water, fully disperse and let stand for 30 minutes, then heat to 75-80 ° C and mix for 15 minutes, then add 8 parts of poly Acrylamide and 3 parts of glutinous rice flour were heated to reflux and kept mixed for 15 minutes. The resulting mixture was cooled to -5-0°C within 5 minutes in an ice-salt bath, and kept mixed for 10 minutes at -5-0°C. Finally, the mixture was Homogenize twice at a homogenization temperature of 65-70°C and a homogenization pressure of 20-25MPa to obtain an aqueous phase solution;

[0023] (2) Preparation of the oil phase: first heat 70 parts of trifluoroethyl methacrylate and 45 parts of allyl methacrylate to 85-90 ° C and mix for 10 minutes, then add 35 parts of divinylbenzene, 25 parts of The pore agent and 2 parts of the initiator are thoroughly mixed, and then microwaved at a microwave frequency of 2450MHz and a p...

Embodiment 3

[0036] After the same batch of monosodium glutamate neutralizing liquid is mixed evenly, it is divided into four parts on average, and then decolorized by the resin prepared in embodiment 1 of the present invention, embodiment 2, and commercially available D201MB resin and D301 resin, and its decolorization rate is measured, the result As shown in Table 1:

[0037] Table 1 Resin Decolorization Ability Determination

[0038] project Example 1 Example 2 D201MB resin D301 resin Decolorization rate 99.65％ 99.58％ 90.36％ 92.17％

[0039] As can be seen from Table 1, the decolorization rate of the resins made in Example 1 and Example 2 of the present invention for the decolorization of monosodium glutamate neutralizing liquid reaches more than 99.5%, which is far higher than the current commercially available food decolorization with D201MB resin and D301 resin. The resin prepared by the invention has a strong decolorization ability to the monosodium glu...

Abstract

The invention discloses resin special for decoloration of a monosodium glutamate neutralizing solution, and relates to the technical field of resin treatment. The resin is prepared from the following raw materials in parts by weight: 60 to 70 parts of trifluoroethyl methacrylate, 40 to 50 parts of allyl methacrylate, 30 to 40 parts of divinyl benzene, 25 to 35 parts of pore-forming agent, 10 to 15 parts of polyoxyethylene, 6 to 11 parts of polyacrylamide, 6 to 11 parts of pentaerythritol ester of hydrogenated rosin, 5 to 9 parts of active magnesium oxide, 3 to 6 parts of microcrystalline cellulose, 3 to 6 parts of glutinous rice flour, 2 to 4 parts of tricetanol phosphate, 2 to 4 parts of propylene glycol alginate, 1 to 2 parts of sesbania gum, 1 to 2 parts of initiating agent, 10 to 15 parts of ethanol and 200 to 250 parts of water. The prepared resin is special for decoloration of the monosodium glutamate neutralizing solution, organic pigments in the monosodium glutamate neutralizing solution can be effectively removed, and the decoloration rate is up to 99.5 percent or more, so that the color of a monosodium glutamate product can be remarkably increased; the regenerability is good, the output of wastewater is small, and regenerated resin still has stronger decoloration ability.

Description

[0001] Technical field: [0002] The invention relates to the technical field of resin processing, in particular to a special resin for neutralizing and decolorizing monosodium glutamate. [0003] Background technique: [0004] The pigments in the MSG neutralizing solution are mainly organic pigments of weak acids, which have the characteristics of relatively large molecular weight. If not removed, it will affect the color of MSG products. MSG products on the market show different color levels with yellowing, which is caused by poor decolorization and iron removal. Traditional decolorization adopts secondary activated carbon decolorization. First, powder carbon is used to remove most impurities and pigments, and then granular carbon is used for second decolorization to ensure the quality of monosodium glutamate. However, this method uses many carbon columns and is large in volume. The regeneration of the carbon columns consumes a large amount of acid and alkali, and produces ...
