What is Potassium Sorbate Ewg?

Potassium Sorbate Ewg, the potassium salt of sorbic acid, is a preservative allowed in my country.It is a white to light yellow scaly crystal, crystal particle or crystal powder, odorless or a little fragrant, and also it is easy to absorb moisture after long-term exposure to the air, as well as is oxidized and also decayed to alter color.Because sorbic acid is insoluble in water and inconvenient to use, Potassium Sorbate Ewg is commonly used.

Potassium Sorbate Ewg Uses

  1. Potassium Sorbate Ewg is mainly used as food preservative, and also used for cosmetic preservation and feed mildew prevention. It has a strong inhibitory effect on spoilage bacteria and mold, and is easily soluble in water and is widely used. Its antibacterial growth effect is stronger than bactericidal effect, the lower the pH value, the stronger the antibacterial effect. Sorbic acid (potassium) can effectively inhibit the activity of mold, yeast and aerobic bacteria, and can also prevent the growth and reproduction of harmful microorganisms such as botulinum, staphylococcus, salmonella, etc. Lactobacillus and other beneficial microorganisms are almost ineffective, and their growth inhibition effect is stronger than bactericidal effect, so as to effectively prolong the preservation time of food and maintain the original flavor of food. Its antiseptic effect is 5-10 times that of similar products sodium benzoate. as cosmetic preservative
  2. Potassium Sorbate Ewg isSee sorbic acid for usage range and dosage (calculated as sorbic acid).

Use of Potassium Sorbate Ewg

1. Being used, it can be straight included, splashed, dipped, splashed with completely dry powder, and processed on product packaging materials. Potassium Sorbate Ewg is incompatible with antacid, oxidizing and also lowering representatives. The antibacterial task of sorbic acid will certainly decrease when encountering non-ionic surfactants and also plastics, and also heavy metal salts can catalyze the oxidation response.

2. Potassium Sorbate Ewg can also respond with sulfur-containing amino acids, but the response can be hindered by including vitamin C, propyl gallate or butylated hydroxytoluene. This remedy is extremely conscious pH when stored in glass containers. Consequently, preparations making use of potassium sorbate as a preservative demand to be tested for the quantity of microbes after being saved for a long time. If sorbic acid solutions are saved in polypropylene, polyvinyl chloride or polyethylene containers without the addition of anti-oxidants, sorbic acid will break down quickly.

3. Potassium Sorbate Ewg is made from sorbic acid and also potassium carbonate after chemical reaction, and the sorbate as well as potassium ions are integrated into Potassium Sorbate Ewg. Since the price of potassium carbonate and potassium benzoate is less than that of sorbic acid, potassium carbonate is unlawfully contributed to the product. Lack of stringent administration is likewise one of the reasons for the existence of phony and also inferior potassium sorbate.

Effect of Potassium Sorbate Ewg on the Activity of Lactic Acid Bacteria

With the rapid development of my country’s feed industry, more and more attention has been paid to the situation that feed and raw materials are contaminated by mold. After the feed and raw materials are moldy, not only their nutritional value is reduced, but also mycotoxins will be produced when they are contaminated by mold. This toxin can not only reduce the production performance and reproductive performance of livestock and poultry, but also lead to the decline of the immune function of the body, causing poisoning and death of livestock, poultry and human beings, directly endangering the health of livestock and poultry and human beings, and causing huge economic losses.

Antifungal agent can inhibit the growth and reproduction of mold, prevent it from producing mycotoxins, ensure the quality of feed and raw materials and prolong the storage time. Generally, when the water content in feed and raw materials exceeds 12%, the effect of using antifungal agent is more obvious. Potassium sorbate is an efficient and safe anti-mildew preservative recommended by the International Food and Agriculture Organization and the World Health Organization, and is widely used in food, beverage, cosmetics, feed and other industries. It has a stable structure and is easily soluble in water. It is an acid mildew inhibitor, but has little effect on facultative anaerobic and absolute anaerobic lactic acid bacteria. Under neutral or alkaline conditions, the inhibitory effect is significantly worse, which mainly depends on the dissociation of acid molecules and the decrease in acid molecules, which affects its inhibitory effect, thus limiting some of its applications.

Lactic acid bacteria, as one of the commonly used strains of microecological preparations, are also commonly used strains of fermented feed, and have broad prospects for development and application. However, in the process of processing micro-ecological preparations and producing fermented feed, we often encounter the situation of mold contamination. How to maintain the activity of lactic acid bacteria and inhibit the reproduction of mold is a problem we have been paying more attention to. This paper mainly studies the effect of different concentrations of potassium sorbate on the activity of lactic acid bacteria. Through research, it is found that 0.2% potassium sorbate has little effect on the activity of lactic acid bacteria, and has a relatively obvious inhibitory effect on mold.

Application of Potassium Sorbate Ewg to Food

Alcoholic foods, soft drink drinks, fresh orange juice, hawthorn juice and also other drinks, as well as other non-alcoholic beverages can add sorbic acid in proportion to lengthen the life span.

Such as soy sauce, sauce items, pickled veggies, kimchi, and so on, adding a proper focus of Potassium Sorbate Ewg option can prevent the issue of mildew growth and also wear and tear.

Sorbic acid can be added to fish cake food, fish sausage, smoked fish products, fish and shrimp prepared in soy sauce, fresh fish, fresh shrimp as well as various other marine items, which can effectively prevent the event of mold in the items and also lengthen the storage space time.

Dried out meat, dried out sausages, or comparable dried out meat products; beef sausages, pork sausages, blended pork as well as beef sausages; general meat products; meat fillings; cooked hen; raw and fresh poultry; Extra food has apparent high quality conservation, as well as the result of extending the preservation time is twice as long as that of the control.

( 1) Vegetables and also fruits: include sorbic acid chemical as well as store at 30 ° C for more than one month, which can maintain the greenness of vegetables as well as fruits unchanged. (2) Apples: The preservative liquid is sprayed externally of the apples and also stored at space temperature level for 4 months before degeneration happens. (3) Tinned veggies: It can avoid the tinplate from rusting.

Sorbic acid can be directly contributed to flour or dough. When making use of, potassium sorbate ought to be dissolved in water or milk initially, and afterwards included in flour or dough.

Used in hard cheese, cheese powder, salty cheese, fresh cheese, emulsified cheese, pre-packaged cheese as well as various other foods. There are 3 means to utilize potassium sorbate, one is to add potassium sorbate to a salt remedy, and afterwards use this salt option to make cheese; the various other is to soak or spray the potassium sorbate service before the finished cheese is offered. The 3rd is to saturate or spray the cheese with a sorbic acid option containing a particular amount of alcohol.

( 1) Potassium sorbate might be included in the milklike margarine.

( 2) Sorbic acid and potassium sorbate are added to margarine in which the solution as well as fat are blended.

Potassium sorbate is made use of in pet food as a chemical since it is effective versus lots of mold and mildews as well as yeasts and is not damaging to family pets as well as the setting.

Both the USA and also the European Union make use of potassium sorbate as a feed additive in pet food. Potassium sorbate can prevent the growth of mold, specifically the development of aflatoxin has an extremely substantial result, so adding potassium sorbate can successfully avoid the development of spoilage microorganisms in the product.

In addition, the neutral preference of potassium sorbate is suitable for usage in pet food, due to the fact that animals are more sensitive to adjustments in food preference than human beings. Besides, as an unsaturated fatty acid, potassium sorbate can be conveniently digested as a food component with no negative results on family pets. Family pet food is prone to wasting throughout storage, transportation as well as sales, so potassium sorbate has a substantial application market in the pet food market.
