Potassium sorbate

LUBON INDUSTRY Co., LTD are specialize in producing Potassium sorbate. Used very broad.

Potassium sorbate is a white to pale yellow crystalline flake, crystalline granule or crystalline powder, odorless or slight odor, hygroscopic long-term exposure to air, oxidation and decomposition and discoloration. Water-soluble potassium sorbate

Has a strong inhibitory effect of spoilage bacteria and fungi, and because of the low toxicity than other preservatives, it has become the world’s leading preservatives. Under acidic conditions, corrosion can give full play the role of a neutral role when low.

Also can be used in Cosmetic preservatives . An organic acid preservatives . Average amount of 0.5% . May be mixed with sorbic acid . Although potassium sorbate soluble in water, easy to use, but its pH 1% solution is 7-8, so there is a tendency to increase the pH of cosmetics, should be taken when using.

Sorbic acid (potassium) in a sealed condition stable, exposed and easy to absorb water, moist air oxidation and discoloration . Potassium sorbate better thermal stability , decomposition temperatures up to 270.

When you use can be added directly, spraying, dipping, powder spray on the packaging material handling and other means.

Potassium sorbate and bases, oxidizing and reducing agents are incompatible. When faced with non-ionic surfactants and plastic sorbic acid antimicrobial activity will be reduced. Heavy metal salt capable of catalyzing the oxidation reaction . Sorbic acid can react with the sulfur-containing amino acids, this reaction may be added Vitamin C, propyl gallate or butyl hydroxy toluene suppressed.

When the solution is kept in a glass container on the pH is very sensitive. Therefore, the use of potassium sorbate as a preservative in the formulation to be stored for a long amount of time after the detection of microorganisms .

If sorbic acid solution stored in polypropylene, polyvinyl chloride or polyethylene containers without added antioxidants, sorbic acid will quickly degrade.

sorbic acid

Lubon Industry Co., Ltd specialized in producing the sorbic acid for several years, this products sell well both at home and abroad.

Volume in Western developed countries is large, but in China a wide range of applications not. Recognized as a safe, efficient preservative food additives, Sorbic acid and potassium in China’s food industry is bound to be more extensive. White or yellowish white crystalline powder; special smell. This product is soluble in ethanol, dissolved in ether, very slightly soluble in water. We buy the packaging (or canned) food, the ingredients often see one of the words “sorbic acid” or “potassium sorbate”, people often mistakenly thought to be components of the fruit, “pear” is. In fact, they are commonly used in food additives! Whether they have no harm to human body, plain consumption is indeed necessary, this product has the following characteristics:

1 Mouldproof effect is good. Mildew proof ability of sorbic acid and potassium was obviously higher than that of benzoic acid and salts, sorbic acid potassium mouldproof effect of 5 to 10 times that of sodium benzoate. Sorbic acid dosage generally between 0.2 1.0 g/kg.

2 . Products with low toxicity and high safety. Sorbate toxicity benzoate only 1/4 . Salt 1/2. Potassium sorbate and safe use in humans ranges : the amount per kg of body weight per day is not more than 25 mg.

3 does not change food characteristics. this product is an unsaturated fatty acid into the body, the body’s metabolic processes involved , the metabolic products of carbon dioxide and water. So , sorbic acid can be seen as part of the food , in food applications , not undermine food color , smell, taste and nutrients.

4 . Wide range of applications. Sorbic acid and potassium can be used in the beverage, wine, condiment, meat product, aquatic products, pickles and so on the many kinds of food, and also have the effect to fresh fruit.

5. Easy to use. In the use of sorbic acid and potassium can be added directly, also can spray or dipping. Because it has the characteristics of the use of flexible, so, the United Nations food and agriculture organization (fao), the world health organization, the United States, Britain, Japan and China, southeast Asia countries, sorbic acid and potassium is recommended as the anti-corrosive antistaling agent a variety of food.

Sulfamic acid aqueous solution has the same strongly acidic with hydrochloric acid, sulfuric acid, etc., so called known solid acid, having a non-volatile, non-toxic to humans and minimal odor characteristics. Sulfamic acid aqueous solution of iron corrosion products slower effect can add some sodium chloride, hydrochloric acid produced so slowly, thereby effectively dissolving the iron deposit. Sulfamic acid aqueous solution can remove scale and corrosion products of iron, steel, copper, stainless steel and other materials equipment surfaces. In addition, it is the only used as a galvanized metal surface cleaning acid. When cleaning using the sulfamic acid solution, the temperature control in general not exceed 66 ℃ (to prevent decomposition of the amino acid) at a concentration of not more than 10%.

In addition ,sulfamic acid can be used as a production acesulfame, cyclamate sweeteners and other raw materials. When used for cleaning metal, salt of sulfamic acid and the majority of metal oxide is soluble in water, and less corrosive to metal amino acid other than a mineral acid. It is also used for boiler cleaning equipment, acidizing oil sludge pit, and also apply to the manufacture of forest herbicides. Flame retardant fabric timber manufacturing, timber, paper, cotton fiber is added a certain amount of sulfamic acid can improve the whiteness of the bleached and can improve the flexibility of the fibers. At the same time, sulfamic acid can also be used in the manufacture of pesticides, pharmaceutical intermediates.
