Background
Calcium propionate is a safe and reliable food and feed mildew preventive approved by the World Health Organization (WHO) and the Food and Agriculture Organization (FAO) of the United nations. Calcium propionate, like other fats, is metabolized and absorbed by human and livestock, and supplies calcium necessary for human and livestock, which is an advantage that other mildewcides cannot compare and is considered as GRAS.
Molecular mass 186.22, white light flaky crystals, or white particles or powder. Has a slightly peculiar smell and is easy to deliquesce in humid air. The monohydrate salt is a colorless monoclinic plate crystal. Is easily soluble in water and slightly soluble in ethanol. Has wide antibacterial effect on mould, yeast, bacteria and the like, can play a role in preventing corrosion when being used in bread and cakes, and has higher corrosion prevention effect when the pH value is lower. Calcium propionate is almost non-toxic to humans. The product can be used in cosmetic as antiseptic, and has a maximum allowable concentration of 2% (calculated as propionic acid). Storing in dry and cool storehouse, and keeping away from rain and moisture during storage and transportation. The propionic acid is used as a raw material and is neutralized by calcium hydroxide to prepare the propionic acid.
Calcium propionate is an acid food preservative, and can produce free propionic acid under acidic conditions, and has antibacterial effect.
