Product Description
Potassium sorbate is the least toxic food preservative and is widely used in the food and feed processing industries. It is also used in industries such as cosmetics, cigarettes, resins, spices, and rubber. However, it is most widely used in food preservation and feed.
The anti-corrosion mechanism of potassium sorbate is the same as that of sorbic acid, which combines with the thiol groups of microbial enzyme systems to destroy many enzyme systems, thereby achieving the goal of inhibiting microbial reproduction. Potassium sorbate can effectively inhibit the activity of molds, aerobic bacteria, and yeast, as well as prevent the proliferation of microorganisms such as Staphylococcus, Botulinun, and Salmonella. However, it is ineffective against anaerobic spores and acidophilic lactobacilli, and its inhibitory effect on development is stronger than its bactericidal effect, thus achieving the goal of extending food preservation time while maintaining the original flavor of the food.
Application of potassium sorbate as a food preservative:
Potassium sorbate is widely used as a food preservative. In 1982, China approved the use and issued a standard, which stipulated that the allowable concentration of flour products, Pickled vegetables, cans, dried fruits, dairy products and condiments was 0.02%~0.1%. Adding 1% potassium sorbate to meat products can significantly inhibit the production of Clostridium botulinun toxin. At the same time, sorbic acid is widely used in low alcohol alcoholic beverages such as alcohol, beer, and wine, and has ideal preservative effects. According to the standards of the International Food and Agriculture Organization, the maximum amount of potassium sorbate in food is 0.28/kg. Using potassium sorbate to treat packaging materials can extend the shelf life of foods such as bread and cheese.
Application in vegetables and fruits:
If fresh vegetables and fruits are not treated with anti-corrosion and preservation in a timely manner, they will quickly lose their luster, moisture, dry and wrinkled surfaces, and are prone to mold causing decay, resulting in unnecessary waste. If potassium sorbate preservative is used on the surface of vegetables and fruits, it can be stored for up to a month at temperatures up to 30 ºC, and the greenness of vegetables and fruits can also be maintained unchanged. After being stored at room temperature for 4 months, only about 5% of apples that were sprayed with potassium sorbate preservation solution on the surface experienced decay and spoilage. Potassium sorbate can also prevent the oxidation and rusting of tinplate on the outer packaging of canned vegetables.
Application in meat products:
Smoked ham, dried sausages, dried meat, and similar dried meat products are briefly soaked in an appropriate concentration of potassium sorbate solution to achieve preservation and preservation. Meat sausage products such as beef sausage and pork sausage are sprayed with a 5% concentration of potassium sorbate solution on their surface to achieve preservation and preservation. You can also directly add an appropriate amount of potassium sorbate to ordinary meat and meat fillings for preservation and preservation. Fresh chicken and cooked chicken can be soaked in different formulas and concentrations of potassium sorbate preservation solution to improve the preservation effect and extend the shelf life. Fresh poultry meat sprayed with potassium sorbate preservation solution on the surface significantly prolongs the time of spoilage compared to similar foods that have not been sprayed with preservation solution, and the preservation time is twice that of the comparison sample.
Application in aquatic products
After adding a mixture of 0.1% to 0.2% sorbic acid and potassium sorbate as preservatives to fish sausages, the product will not spoil after being stored at temperatures up to 30 ºC for two weeks, while the control sample under the same environmental conditions will spoil after being stored for one week. When the temperature is maintained at 10-15 ºC and the pH value inside the fish sausage is controlled to be less than 6, this sausage can be stored for seven weeks without spoilage. In general, the pH value of fish cake products is between 6.8 and 7.2, and potassium sorbate or its mixture with sorbic acid can be used for preservation and preservation. But when using a mixture, it is important to control the proportion of sorbic acid, as sorbic acid is an acidic preservative, while fish cake products are at low pH conditions, which can affect their elasticity. So in order to reasonably solve this contradiction, it is necessary to reduce the content of sorbic acid in the mixture. Dried fish products are relatively dry. Generally, products with a moisture content below 30% do not produce bacterial decay, but are prone to mold. If an appropriate amount of potassium sorbate is added to dried fish products, it can effectively prevent the occurrence of this moldy phenomenon. Smoked fish products can be preserved and preserved by spraying a 5% to 10% concentration of potassium sorbate solution before, during, or after the smoking process. Fish and shrimp cooked in soy sauce can be stored for two months at a temperature of 10-15 ºC without spoilage after adding an appropriate amount of potassium sorbate. Thoroughly clean fresh fish, shrimp, or other fresh aquatic products, immerse them in an appropriate concentration of potassium sorbate preservation solution for 20 seconds, and then remove them. Remove the preservation solution and refrigerate it to effectively extend its shelf life.
Application in soy sauce and pickled vegetable products
Adding an appropriate amount of potassium sorbate to soy sauce can store it at high temperature for 70 days without causing spoilage and mold. When using potassium sorbate to preserve beetroot, pickled cucumbers, and other pickled products, an appropriate amount of potassium sorbate can be added to vinegar containing salt. Usually, in order to avoid the occurrence of salt water turbidity in pickled vegetable products, spices, table salt, and potassium sorbate can be dissolved in water before adding vinegar. Kimchi is preserved and preserved by directly adding a mixture of salt and potassium sorbate.
Application in pastries
When potassium sorbate is used as a preservative for pastries, it should first be dissolved in water or milk, and then directly added to flour or dough. When using potassium sorbate to preserve and preserve starch foods, it is best to first acidify the material with a small amount of vinegar, as potassium sorbate has the best antibacterial and preservative effect when it is in an environment with a pH value below 5-6.
Application in beverages
Potassium sorbate can be added to various beverages such as fruit and vegetable juice drinks, carbonated drinks, and protein drinks. The addition of potassium sorbate greatly prolongs the shelf life of products.
Application in Candy and Candy Products
Peanut sugar, almond sugar, and general sandwich sugar can be directly added with an appropriate amount of potassium sorbate for preservation. In order to ensure the anti-corrosion and fresh-keeping effect of some high sugar content candy products, the amount of potassium sorbate added should be appropriately increased.
The application of potassium sorbate in the animal feed industry:
Both the United States and the European Union use potassium sorbate as a statutory feed additive in animal feed. Potassium sorbate can inhibit the growth of mold in feed, especially the formation of aflatoxin, which has a very significant effect. Therefore, adding potassium sorbate can effectively prevent feed spoilage and can still resist microbial growth in animal intestines. In addition, the neutral taste of potassium sorbate is suitable for use in feed because animals are more sensitive to changes in food taste than humans. In addition, as an unsaturated fatty acid, potassium sorbate can be considered as a feed ingredient and is easily digestible without any adverse effects on animals. Feed is prone to spoilage during storage, transportation, and sales, thus the application market of potassium sorbate in the feed industry is huge.
Potassium sorbate is mainly used as a food preservative due to its strong inhibitory effect on mold and spoilage bacteria, and its easy solubility in water, making it widely used. Potassium sorbate has been recommended by the Food and Agriculture Organization of the United Nations as a safe and efficient food preservative. Potassium sorbate has the characteristics of low toxicity, good anti mold effect, unchanged original properties of food, convenient use, and wide application range. Therefore, many developed countries have already used potassium sorbate as a good and efficient preservative, widely used in food. At present, potassium sorbate is also widely used in the Chinese food industry. With the continuous breakthroughs in production costs and technology, potassium sorbate, as a low toxicity, safe, and efficient food preservative, will continue to expand its application scope.
