[0113] The preparation method of glyceryl monocaprylate in step S101 comprises:

[0114] (1) Acidic catalyst is added in caprylic acid and dimethyl carbonate, set reaction temperature and reaction time, until gas chromatography monitors octanoic acid reaction is complete, add alkali and adjust pH value to neutrality, decompression distills off excessive dicarbonate methyl ester to obtain crude methyl octanoate.

[0115] (2) Add the composite catalyst to the crude product of methyl caprylate and glycerin, adjust the temperature and reaction time until the reaction of methyl caprylate is complete, cool to room temperature and filter, evaporate excess glycerin to obtain glyceryl monocaprylate with a purity of 85%. .

[0116] The acidic catalyst is p-toluenesulfonic acid, concentrated sulfuric acid, phosphoric acid, phosphotungstic acid or 723 type strongly acidic styrene-based cation exchange resin.

[0117] The equivalent ratio of the acidic catalyst, octanoic acid and dimethy...

Abstract

The invention belongs to the technical field of food preservation and discloses a fresh noodle preservative and a preparation method thereof. The fresh noodle preservative is prepared from 1-2 parts of glycerol monocaprylate, 2-5 parts of antioxidant composition, 3-8 parts of citric acid, 1.5-3 parts of sorbitol, 0.5-2 parts of propylene glycol, 2-5 parts of sodium chloride, 1-2 parts of carboxymethyl cellulose and 2-4 parts of dietary alkali. The preservative has the effects of synthesizing and enhancing vitamin C by adopting the combination of a bacteriostatic agent, antioxidant and auxiliaries, has simple formula, simple production process, low cost and convenience in use, has low price but remarkable preservation effect, completely accords with the national food hygienic safety standard and can meet the requirement of industrial production. Furthermore, high purity glycerol monocaprylate and propylene glycol can be obtained by a glycerol monocaprylate preparation method and a propylene glycol preparation method, and the high-quality preservative can be prepared.

Description

technical field [0001] The invention belongs to the technical field of food preservation, and in particular relates to a fresh-keeping agent for fresh noodles and a preparation method thereof. Background technique [0002] Currently, the closest prior art: [0003] China's traditional eating habits have strong vitality. Although noodle products such as instant noodles and dried noodles have occupied a certain market, people are still willing to go to the farmer's market to buy fresh wet noodles rolled on site due to considerations such as nutrition and taste. Even the "new army" of instant noodles - LL noodles (long life noodles, also known as wet instant noodles, udon noodles, fresh instant noodles), it is difficult to change people's habit of pursuing natural taste. After all, instant noodles are people's emergency food, and they cannot change people's traditional staple food habits. Therefore, postgraduate wet noodles have a good prospect. However, due to the high moi...
