What is l Sorbic Acid?

l Sorbic Acid, Colorless needle crystal or white crystalline powder; stable to light and heat, but easy to oxidize and change color; melting point 134.5 °C, boiling point 228 °C (decomposition); pH value of saturated aqueous solution is 3.6; slightly soluble in water, easily soluble In methanol, ethanol, glacial acetic acid, acetone, soluble in acetone, benzene, carbon tetrachloride, sour taste, non-toxic. The chemical properties are lively, and it is easy to carry out addition reactions to generate saturated compounds. It has bacteriostatic effect on mold, yeast and aerobic bacteria, and is almost ineffective against anaerobic Clostridium spp and Lactobacillus acidophilus.


l Sorbic Acid and its potassium salt are suitable for use in the range of pH=4.5~6. Its mechanism of action is that it can combine with the sulfhydryl group in the microbial enzyme, destroy the function of the enzyme and cause the reproduction to be blocked. Because this product is an unsaturated fatty acid, it can participate in normal metabolism in the body, and finally oxidized to carbon dioxide and water, so it is harmless to the human body. The acceptable daily intake (ADI) of human body is 0~25mg/kg (calculated as sorbic acid), which can be used as soy sauce, vinegar, jam, fruit juice, sherbet, wine, pickles, preserves, cakes, sausages, cheese and canned food Preservatives for foods such as food (the dosage is 0.2 to 2.0 g/kg).

l Sorbic Acid and its sodium salt can inhibit the growth of molds and have been used as food preservatives for a long time, especially at low pH values, as an undissociated acid to play a preservative role. Sorbic acid has the characteristics that other preservatives do not have, that is, it has strong preservative selectivity. It can inhibit the growth of harmful bacteria to humans, but is harmless to bacteria that are beneficial to humans. For example, it can inhibit the growth of cheese mold but not. Does not affect the growth of bacteria that help cheese ripen. Therefore, sorbic acid is widely used in the food industry as a preservative for cheese, cakes and other pastries. Tests have determined that the maximum allowable amount of sorbic acid in food is 0.1%. Mainly used for mildew prevention of cheese, pickled vegetables, dried fruits, fruit juices, fruit syrups, beverages, preserves, bread, candies, etc. It is also used for the preservation of fish and meat products. It is also used in cosmetics, medicine, feed and so on. It is produced by the method of condensation and decomposition of crotonaldehyde and ketene in industry.

On top of that, it likewise has applications in cosmetics, medicine and also feed.
  4. l Sorbic Acid has the effect of preventing the growth as well as recreation of microbes. Its poisoning is only 1/4 of benzoic acid, and also it tends to change benzoic acid. In the food industry, it is primarily utilized for anti-mildew of cheese, pickled veggies, dried out fruit, fruit juice, fruit syrup, beverage, preserves, bread, sweet, etc. It is likewise utilized for the conservation of fish as well as meat products.
    Sorbic acid is likewise used as a preservative in the pharmaceutical market, light commercial cosmetics, flue-cured cigarette leaves, and as an insecticide. In addition, it is additionally made use of to formulate reagents; as an unsaturated acid, it is utilized in material, fragrance as well as rubber markets; it is also used in feed.
  5. l Sorbic Acid is a new kind of food preservative, which can properly prevent the development of germs, mold and mildews as well as yeast without damaging effects on food. It can take part in human metabolism. It is an internationally acknowledged safe food preservative as well as can also be utilized in medication. In industry, light market, cosmetics and also other sectors, as an unsaturated acid, it can likewise be made use of in material, fragrance as well as rubber sectors.
  6. l Sorbic Acid is a mold and mildew as well as yeast inhibitor. Food mildew prevention. Drying out oil denaturant. fungicide.

l Sorbic Acid Production Method

l Sorbic Acid can be obtained by sorbaldehyde oxidation method, acetone and crotonaldehyde condensation method, and malonic acid and crotonaldehyde condensation method, but it is produced by ketene method at home and abroad. In addition, the butadiene route has good development prospects due to the low cost of raw materials. Butadiene route Butadiene and acetic acid are catalyzed by manganese acetate, and 140 °C is added and compressed to obtain γ-ethylene-γ-butyrolactone. γ-ethylene-γ-butyrolactone can be obtained by hydrolysis of γ-ethylene-γ-butyrolactone under acidic conditions at 100 °C. Sorbic acid. The acetic acid vapor containing the alkyl phosphate catalyst stays in the cracking tube above 700°C for 0.3s, and the generated gas mixture converts the catalyst into ammonium phosphate with ammonia gas and deactivates it. Cool to -10~30℃ step by step to remove water, acetic acid and acetic anhydride; ketene gas is absorbed by crotonaldehyde, and polyhexene is generated under the catalysis of boron fluoride (or zinc chloride, cobalt chloride, etc.) -4,5-β-lactone (referred to as polyester); the polyester is hydrolyzed under acidic conditions, and after cooling, crude l Sorbic Acid is precipitated, and then recrystallized with 3 to 4 times the amount of 60% ethanol to obtain l Sorbic Acid.

l Application of Sorbic Acid in Meat and Aquatic Products

For salted fish, potassium sorbate can be added to salt water or mixed with dry table salt and added to fish products. The addition of potassium sorbate or l Sorbic Acid to short-term preservation of food products such as fish tacos, herring and salmon fillets is effective and durable against bacterial contamination, even during storage and in open packaging.

l Sorbic Acid and potassium sorbate are effective in preventing mold and yeast corrosion of air-dried and smoked fish. For example, dried salted cod is processed with sorbic acid and salt at a content of 2% to 4%.

Dried cod can be dipped or sprayed with a 5%-10% potassium sorbate solution to prevent subsequent mold corrosion. Before or after smoking dried fish, a 5%-10% potassium sorbate solution can be sprayed to inhibit mold growth. The concentration of the final product should be 0.05% – 0.15%. By adding 0.4%-0.8% powdered sorbic acid, the shelf life of shrimp can be extended.

Potassium sorbate has obvious antiseptic and antibacterial effect than sodium benzoate, especially has a strong antifungal effect. Potassium sorbate soaked fresh pork and fresh chicken can prolong the shelf life and have no adverse effect on the sensory characteristics after cooking. Adding potassium sorbate to cured bacon products reduces the amount of sodium nitrite, which reduces the potential for the formation of carcinogenic nitrosamines. At the same time, it has no adverse effect on the color and fragrance of the product. Dry and hard sausages, smoked ham and jerky and similar products can be soaked in 5%-20% potassium sorbate solution to prevent mold corrosion.

Mold growing on the casing can be prevented by adding 0.2%-0.4% l Sorbic Acid or potassium sorbate. For some Frankfurt boiled sausages (with or without casing), 0.05%-0.08% sorbic acid can be added during the slicing process, or the prepared sausages can be surface-treated with 5% potassium sorbate solution to prevent mold growth. .

Since potassium sorbate is an acidic preservative, it is recommended to use organic acids such as citric acid and lactic acid salts. Potassium sorbate has a long-lasting antiseptic effect.

Potassium sorbate preservative is mainly because sorbic acid can inhibit the action of dehydrogenase system in microorganisms such as mold, and can inhibit the growth of mold and the like. However, when the mold is seriously contaminated or has begun to decay, the mold can use potassium sorbate as a medium, so that sorbic acid has no effect. Therefore, adding potassium sorbate is only one of the ways to prolong the shelf life. The preservation of meat products is also related to the temperature and water activity of the raw materials, and is closely related to the control of external and internal factors.
