Sodium Diacetate Usage and Synthesis.

Sodium diacetate is used for grain, food and feed mold has a highly effective mold inhibition effect, especially for aflatoxin has a strong inhibitory effect, it is through the penetration of the microbial cell wall, interfering with intracellular growth of various enzyme systems, can be highly effective in inhibiting the common Aspergillus flavus, Aspergillus niger, toxigenic molds, Penicillium cordatum, gray-green Aspergillus, Aspergillus albicans, etc. More than ten kinds of mycotoxins and Escherichia coli, listeria, gram-negative bacteria growth and spread of bacteria. Negative bacteria and other bacteria occur, grow and spread, and its mold inhibition effect is better than mold inhibitor calcium propionate.

Foreign countries have been used in large quantities for grain, food and feed mold preservation, domestic is still in the initial stage.

In our country sodium diacetate is a new type of multi-functional green food additives, mainly used for grain, food mold, preservation, preservation, seasoning and improve the nutritional value, in addition, also widely used in baked goods, spices, sauces, snow vegetables, mustard greens, meat, juice drinks and other processed foods, is the replacement of sorbic acid \sorbate potassium, benzoic acid \benzoic acid, sodium propionate, calcium propionate, propionic acid, sodium sodium propionate, p-antelinum-based Sodium diacetate is the ideal product to replace preservatives such as potassium sorbate, sodium benzoate, calcium propionate, sodium propionate, butyl benzoate, dimethyl fumarate, etc. Sodium diacetate needs to be sealed and stored in a cool place below 40 degrees Celsius, protected from sunlight and moisture.

Uses of Sodium Diacetate.

1. Sodium diacetate is a multifunctional edible chemical. It is mainly used as preservative, mold inhibitor, chelating agent, flavoring agent, PH adjusting agent, preservative of meat products in food and feed industry, and is also the main ingredient of compound mold inhibitor.

2. This product can be mixed with other flavorings and sweeteners. It can be used as acidifier of food, also can be used as mold inhibitor and food quality improver. Widely used in food, feed, grain and silage mold additives (mainly as mold preservation, improve nutritional value).

It is also used as acidifier, homogenizer, buffer, polyvalent chelating agent, antirust agent and anti-mildew agent for bread in printing and dyeing industry.

Preparation of Sodium Diacetate.

Product Method of Sodium Diacetate.

Reaction of acetic acid with sodium carbonate

Sodium carbonate 5.3g (0.05mo1) and water 2mL was added to the reaction bottle, stirring to raise the temperature to 40 ℃ began to slowly drop glacial acetic acid 12.0g (0.2mo1). After dropping at 80 ℃ reaction 4h, cooling crystallization, filtration; filtrate and then concentrated crystallization, combined two white crystals, drying to get 13.6g of product, yield 95.8%.

Acetic acid monoethyl anhydride and sodium carbonate reaction

Add 9.2g of sodium carbonate to 8.4mI. of acetic anhydride, evenly wetted and then add 13mL of acetic acid in batches. After stirring for a certain period of time, after standing, drying to get 24.6g of products. can also be sodium carbonate 5.3g (0.05m01) and 3mL of water into the reaction bottle, stirring and mixing to 40%, began to staggered drops of glacial acetic acid 6.0g (0.1mo1) and acetic anhydride 5.1g (0.05m01), drops continue to continue to 70 ℃ reaction for 3h. Cooled to room temperature, crystallization and filtration, the filtrate concentrated Recrystallize. Combine the two crystals, drying to get 13.7g of product, yield 96.5%.
