introduction | potassium sorbate is the potassium salt of sorbic acid and is a preservative allowed in China. It is white to light yellow scaly crystals, crystal particles or crystal powder, odorless or slightly smelly, long-term exposure to the air easy to absorb moisture, oxidation decomposition and discoloration. Potassium sorbate is easily soluble in water, soluble in propylene glycol and ethanol. Because sorbic acid is difficult to dissolve in water and inconvenient to use, potassium sorbate is commonly used. |
properties | white to light yellow scaly crystals, crystalline powder or granular. Odorless or slightly smelly. Long-term storage in the air is easy to absorb moisture and oxidize and decompose. Soluble in water. Soluble in propylene glycol and ethanol. Sorbic acid (potassium) is stable in a sealed state, exposed to humid air, it is easy to absorb water, oxidize and color. Potassium sorbate has good thermal stability and its decomposition temperature is as high as 270 ℃. |
use | potassium sorbate is mainly used as a food preservative, as well as cosmetic preservative 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 molds, yeasts and aerobic bacteria, and can also prevent the growth and reproduction of harmful microorganisms such as botulinum, Staphylococcus, and Salmonella. Beneficial microorganisms such as Lactobacillus are almost ineffective, and their inhibitory effect on development is stronger than bactericidal effect, so as to effectively extend the storage time of food and maintain the flavor of the original food. Its anti-corrosion effect is 5-10 times that of similar products sodium benzoate. As a cosmetic preservative potassium sorbate is an internationally recognized low-toxicity and high-efficiency acid food preservative, which has the same preservative effect as sorbic acid. See Sorbic Acid for the scope and dosage of use (in terms of sorbic acid). potassium sorbate is an internationally recognized low-toxicity and high-efficiency acid preservative, which has the same antiseptic effect as sorbic acid. See Sorbic Acid for the scope and dosage of use (in terms of sorbic acid). Used as a preservative and antifungal agent in the food industry Used as a food preservative. Inhibitors of mold and yeast. |
scope of use | when potassium sorbate and sorbic acid are used at the same time, the dosage shall be calculated as sorbic acid and shall not exceed the maximum dosage. China's "Hygienic Standard for the Use of Food Additives" (GB2760-1996) stipulates the usage amount: (g/kg) meat, fish, eggs and poultry products: ≤ 0.075; Fruit and vegetable preservation, carbonated beverage: ≤ 0.2; Pickles, fruit juice, candied fruit, jelly: ≤ 0.5; Soy sauce, vinegar, jam, soft candy, bread: ≤ 0.1; Concentrated fruit and vegetable pulp or juice for food industry: ≤ 2.0. Soy sauce, vinegar, jam, hydrogenated vegetable oil, soft candy, dried fish products, instant bean food, cakes, stuffing, bread, cakes, moon cakes, instant jellyfish, lactic acid bacteria drinks ≤ 1.0 g/kg |
manufacturing method | mainly adopts neutralization method. It is obtained by neutralizing sorbic acid with potassium carbonate or potassium hydroxide. |
production method | sorbic acid is added into the reaction kettle, then sorbic acid is added with water of 66% mass, and 49% potassium hydroxide solution is added dropwise at 45 ℃ until the pH of the reaction solution is 8, and the reaction takes about 45min. Add a certain amount of activated carbon, vacuum filter, at 40-45 DEG C will be reduced pressure evaporation of the filtrate for 3-4h, meet the requirements of the temperature to 70 DEG C discharge. Crystallization is obtained by centrifugal dehydration, mother liquor is recovered, and finally the product is dried at 105 ℃. sorbic acid is added into the reaction kettle, then water with sorbic acid mass 66% is added, and 49% potassium hydroxide solution is added dropwise at 45 ℃ until the reaction solution Ph = 8, and the reaction takes about 45min.
