food preservatives

Application1) Food industry. Potassium sorbate, as the least toxic food preservative, is widely used in the food and feed processing industries, as well as in industries such as cosmetics, cigarettes, resins, spices, and rubber. Among them, it is most widely used in food preservation and feed .2) Feed industry. The United States and the European Union use potassium sorbate as a legal feed additive in animal feed. Potassium sorbate can inhibit the growth of fungi 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 anima...

Sodium benzoate is a common food preservative. It is the sodium salt of benzoic acid and has the chemical formula C7H5NaO2. Sodium benzoate is used in a wide range of food and beverage products to prevent the growth of bacteria, yeasts, and molds, thereby increasing their shelf life. Here are some key points about sodium benzoate: Function: Sodium benzoate is an effective preservative due to its ability to inhibit the growth of microorganisms such as bacteria and fungi. It is commonly used in acidic foods and beverages, including carbonated drinks, fruit juices, pickles, salad dressings, and sauces. Safety: Sodium benzoate is generally considered safe for consumption when used in the recommended amounts. It has been approved by regulatory agencies such as the U.S. Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA). However, some individuals may be sensitive or have allergies to sodium benzoate, and high levels of intake may have adverse effe...

Calcium acetate is the acetate salt of calcium, a white to brown or gray crystal with a special odor. The common name for calcium acetate is calcium acetate. Anhydrous calcium acetate has excellent hygroscopicity, so common calcium acetate exists in the form of monohydrate (Ca (CH3COO) 2. H2O).If alcohol is added to a saturated calcium acetate solution, it will generate a semi-solid, flammable colloid, much like canned fuel products, such as Sterno. California Snowball is actually a mixture of calcium acetate and ethanol. The resulting colloidal color is white, stacked like snowballs. PURPOSE1.Calcium acetate is an acetate, a commonly used chemical reagent in many organic reactions. It is the main component of vinegar, which contributes to its unique taste and aroma. It is used to synthesize dye sensitized solar cells. 2.Calcium acetate is a good food calcium fortifier with better absorption effect than inorganic calcium. Can be used in infant and toddler food, with a dosage of 3.0-6.0...

Sodium Acetate is colorless and odorless crystals that can be weathered and flammable in the air. Soluble in water and ether, slightly soluble in ethanol. The melting point of sodium acetate trihydrate is 58 ℃, the relative density is 1.45, and the spontaneous ignition point is 607.2 ℃. Remove 3 molecules of water at 123 ℃. The melting point of anhydrous sodium acetate is 324 ℃, and the relative density is 1.528. Application 1.Used as an esterification agent for organic synthesis, as well as in many fields such as photography pharmaceuticals, pharmaceuticals, printing and dyeing mordants, buffering agents, chemical reagents, meat preservation, pigments, tanning, etc. It can be used to produce various chemical products, such as furan acrylic acid, acetate, and chloroacetic acid. As a buffering agent for seasoning, this product can alleviate unpleasant odors and prevent discoloration, and has a certain anti mold effect. It can also be used as sour agent for sauce, pickled Chinese cabbage...

CharacterColorless transparent crystals, particles, or white crystalline powders. No odor or slightly propionic acid odor. Easy to deliquescence, highly soluble in water, soluble in ethanol, slightly soluble in acetone. ApplicationIn the food industry, it is used as a leavening agent, dough regulator, buffer, tissue improver, curing agent, nutritional supplement, chelating agent, etc. As a leavening agent for baked goods and pastries; Yeast promoter, buffer, pectin curing agent (gel effect) for bread and biscuit; Yeast ingredients, tissue improvers for meat products, etc. Sodium propionate is used as a food preservative and mold inhibitor, and can be used alone or in combination with propionic acid and sorbic acid. Because it is alkaline, it is more suitable for pastry making than calcium propionate. Propionate salts are of great significance for the preservation of baked foods such as bread, pastries, and biscuits, because the ionization constant of propionic acid is small, so it stil...

Calcium propionate is a white crystalline particle or crystalline powder. Odorless or slightly propionic acid odor, hygroscopic, easily soluble in water, insoluble in alcohols. PurposeThe antibacterial effect of calcium propionate liquid as a wet acid type preservative is influenced by the pH of the environment. The minimum inhibitory concentration is 0.01% at pH 5.0 and 0.5% at pH 6.5. It has a strong inhibitory effect on various types of fungi, aerobic Bacillus or Gram negative bacteria in acidic media. It has a special effect on preventing the production of aflatoxin, but is almost ineffective on yeast. In addition, it also serves as a preservative for food.1.Used as a food preservative and antifungal agent, it has a wide range of inhibitory effects on fungi, yeast, and bacteria2.Used as an analytical reagent3.Preservatives; Antimold agents.4.Calcium propionate is also an acidic food preservative, and its antibacterial effect is influenced by the pH value of the environment.
