The application fields and technical points of naturally fermented calcium propionatemainly include the following aspects:
Feed Industry: In livestock and poultry breeding, calcium propionate is added to fermented feed as a preservative, which can effectively inhibit the spoilage and fermentation of the feed, extend the shelf life, and increase the calcium content in the feed, which is beneficial to the growth and development of animals. healthy. The addition amount is generally 0.1% to 0.3% per ton of feed. After addition, it can significantly reduce the pH value of the feed, inhibit the reproduction of harmful microorganisms, improve the texture of the feed, and increase the utilization rate of feed by livestock and poultry.
Food Industry: In the food industry, calcium propionate is widely used in bread, pastries, dairy products, canned fruits and other foods. It can effectively inhibit the growth of mold, prevent food from becoming moldy and spoilage, and extend the shelf life. Especially under acidic conditions, the antiseptic effect of calcium propionate is more significant. In addition, calcium propionate can also supplement the calcium needed by the human body and improve the nutritional value of food.
Cosmetics Industry: In cosmetics, calcium propionate is used as a preservative, with a maximum allowable concentration of 2% (calculated as propionic acid). Because it is almost non-toxic to the human body, calcium propionate has broad application prospects in cosmetics.
Technical points
Antibacterial and antiseptic: Calcium propionate has a wide range of antibacterial effects on molds, yeasts and bacteria, especially when the pH value is low, its antiseptic effect is higher. A single molecule of propionic acid can form a high osmotic pressure around the mold cells, causing dehydration of the mold cells, thereby effectively inhibiting their growth; at the same time, the H+ dissociated from propionic acid can penetrate the mold cell wall, inhibit the activity of intracellular enzymes, and hinder the growth of the mold. Breed.
High safety: Natural calcium propionate is approved by the World Health Organization (WHO) and the Food and Agriculture Organization of the United Nations (FAO) as a safe and reliable antifungal agent for food and feed, and is almost non-toxic to the human body.
Storage conditions: Calcium propionate should be stored in a dry and cool warehouse, protected from rain and moisture to ensure its stability and effectiveness.
