Guangzhou city is still good biological technology Co., Ltd.

English: sorbate C6H7KO2 molecular formula potassium molecular weight: 150.22CAS:24634-61-5. Name: Hexadienoic - (2, 4) - 2,4- acid potassium; potassium sorbate

Characters: white particles, no odor or a slight odor. In the air is not stable. Can be oxidized coloring. Molecular weight 150.22. Moisture absorption. Soluble in water and ethanol.

Sorbic acid (potassium) could effectively inhibit mold, yeast, and aerobic bacterial activity, but also to prevent the growth and reproduction of botulinum, Staphylococcus aureus, Salmonella and other harmful microorganisms, but the Lactobacillus beneficial microorganisms such as anaerobic spore forming bacteria and eosinophil almost invalid, which restrain the development of the role is stronger than the sterilization function, so as to effectively prolong the storage time of food and keep original food flavor.

The anti-corrosion effect is similar to the 5-10 times of sodium benzoate.

Safety: due to the acid (potassium) is an unsaturated fatty acid (salt) it can be absorbed by the body's metabolic system and quickly decomposed into carbon dioxide and water, no residue in the body.

Stability: potassium (potassium) in a sealed state, stable, exposed to the humid air, easy to absorb water, oxidation and discoloration. Potassium potassium potassium fertilizer had better thermal stability, and the decomposition temperature was 270.

Scope of application: has been widely used in food, beverages, pickles, tobacco, medicine, cosmetics, agricultural products, feed and other industries, from the development trend and its application range is still expanding. Potassium acid (potassium) is an acid preservative, in close to neutral (PH6.0-6.5) in the food still has a better corrosion protection, and the effect of benzoic acid (sodium) in PH>4, the effect has been significantly decreased, and there is a bad taste.

Properties: colorless to white scale crystal, crystalline powder or granular crystals. Odorless or slight odor. Moisture absorption. In the air is not stable, easy to be oxidized coloring. Melting point of 270 degrees Celsius, above the melting point decomposition. Soluble in water and ethanol.

Purpose: inhibition of fungal, yeast and aerobic bacteria were therefore used as a food preservative.

Storage and transportation: the product is stored in a dry, cool, ventilated place. Not to be mixed with toxic substances.

Product description:

Potassium potassium is white or light yellow granule or powder, slight smell. In the air is easy to be oxidized and the color becomes dark. There is moisture absorption, easy to dissolve in water, 59g/100mL (water), 1% water solution pH7~8. Anti corrosion ability, to light, heat is relatively stable.

Potassium sorbate is mainly used as food preservatives, also used preservatives in cosmetics and feed mildew etc.. Has a strong inhibition of the role of spoilage bacteria and fungi, but also easily soluble in water to obtain a wide range of applications. Its antibacterial activity is stronger than the bactericidal action, the lower the pH value, the stronger the antibacterial effect. Use and use limited to the same as the acid. Potassium acid, potassium and the use of the same time, the amount of acid, not exceeding the maximum usage. Our country "food additive use health standards" (GB2760-1996) require the use of volume: (g / kg) of meat, fish, eggs, poultry products: < 0.075.
