Sodium dehydroacetate


 


Sodium dehydroacetate, also known as sodium dehydroacetate monohydrate, chemical name is 3 - (1-hydroxyethylene) - 6-methyl-1,2-pyran-2,4 (3H) - diketone sodium (3-acetyl-6-methyl-2-oxo-2H-pyran-4-olate; 2H-pyran-2,4 (3H) - dione. The molecular formula is C8H7NaO4. CAS 4418-26-2


White or near white crystalline powder, non-toxic and odorless. Soluble in water, glycerin, propylene glycol, slightly soluble in ethanol and acetone. Its aqueous solution did not change at 120 C and remained stable to be neutral or slightly alkaline after heating at 120 C for 2 hours. Light resistant and heat resistant, it can be used as preservatives, preservative insecticides, food additives.


Main uses


Sodium dehydroacetate is a new generation of food preservatives after sodium benzoate, Nipagin and potassium sorbate. It has a good inhibitory effect on mold, yeast and bacteria. It is widely used in the processing of beverage, food and feed. It can prolong the storage period and avoid the loss of mold. Its mechanism is to effectively penetrate into the cell body, inhibit the respiration of microorganisms, so as to achieve antisepsis, mold preservation and moisture preservation.


Sodium dehydroacetate has broad-spectrum antimicrobial ability, especially to mold and yeast. Sodium dehydroacetate has strong effect on yeast and mold which cause food spoilage. The effective inhibitory concentration is 0.05% - 0.1%, and the general dosage is 0.03% - 0.05%.


Mainly used for sufu, pickles, jam (maximum dosage 0.3g/Kg); soup, pastries and cheese, cream, margarine, etc. (maximum dosage 0.5g/Kg); in salted vegetables, the maximum dosage of 0.3g/Kg (see GBP70).


Sodium dehydroacetate is light-resistant and heat-resistant, and does not decompose and evaporate with water vapor during food processing. Experiments show that sodium dehydroacetate has several non-toxic side effects, high safety and no abnormal odor when used in food. Therefore, sodium dehydroacetate has been widely welcomed by food enterprises in recent years. It is used in butter, soup (seasoning, instant soup), bread, cake, cakes, egg yolk pie, preserved bean curd, jelly and thick food. Fruit pulp, moon cake, stuffing, bean paste, Lian Rong and so on are widely used.

Toxicity and environmental impact


Sodium dehydro acetate is harmless to the environment and harmless to the environment.


Packaging, transportation and storage


Lined with plastic 25Kg cardboard barrels, 25Kg paper, plastic composite bags, 1Kg plastic bags. Transported by non-toxic, non inflammable materials, stored in dry, ventilated, shelter and shelter.


 


The main characteristics of sodium deacetate are:


1, it is a safe broad spectrum preservative. Long-term exposure to the skin without irritant damage; in aqueous solution, gradually degraded to acetic acid, no accumulation, harmless to the human body. Boil and bake in water.


Food does not destroy, do not deteriorate, do not volatilize. It can be widely used in classified foods prescribed by GB2760.


2, use does not affect the taste and taste of food.


3, less added amount, good anticorrosive effect. The effective concentration was only 1/5 to 1/10 of sodium benzoate, and the dosage was only 0.1-0.5. It had strong inhibitory effect on yeast, mold and bacterial reproduction, especially.


It is the strongest inhibition to yeasts and molds which cause food spoilage.


4, there is no special requirement for external conditions. Normal temperature, atmospheric pressure, temperature can be used in general conditions, without stringent requirements for production process; its anticorrosion effect is still effective in acidic, alkaline and heating conditions, namely


When the pH value was 5, the inhibition of yeast was still twice as great as that of sodium benzoate, and it was stable to light and heat, and had no effect on the antimicrobial and antiseptic efficacy of yeast when heated at 120 C for 2 hours.


 


Usage and storage conditions:


1, according to the dosage requirements, add to the food mix.


2. Prepare the solution to soak or spray.


3, this product should not be eaten directly. When used in food, can not be mixed with acidic materials or put together, should make sodium dehydroacetate and products mixed evenly and then add acidic materials.


4, store in a cool, dry place, pay attention to moisture-proof. It is strictly forbidden to store together with toxic and harmful substances and chemical products.
