1. Calcium Propionate
Calcium propionate CAS 4075-81-4, E282, EINECS 223-795-8, molecular formula 2(C3H5O2)-Ca, molecular weight 186.22.
Calcium propionate is white light scale-like crystals, or white granules or powder. Slightly peculiar odor, easily deliquescent in the humid air. The monohydrate salt is a colorless monoclinic crystal with a plate shape. Easily soluble in water, slightly soluble in ethanol. It has a wide range of antibacterial effects on mold, yeast, bacteria, etc. It can be used in bread and pastry as a preservative.
2. Sodium propionate
Sodium propionate, CAS 137-40-6, E281, molecular formula CH3CH2COONa, relative molecular mass 96.06.
Sodium propionate is colorless transparent crystalline or granular crystalline powder with a slightly special odor. The monohydrate salt is a colorless crystal with hygroscopicity. Soluble in water and ethanol, solubility in 10% water is about 100 (15℃), pH 8.5~10.5.
3. Effective PH of calcium propionate and sodium propionate
Calcium propionate can inhibit the multiplication of Bacillus subtilis during dough fermentation, the minimum inhibition mass fraction is 0.01% at pH 5.0, 0.188% is needed at pH 5.8, and the optimum pH should be lower than 5.5
Sodium propionate is also a food preservative, and its antibacterial effect is affected by the pH of the environment. The minimum inhibition concentration is 0.01% at pH 5.0 and 0.5% at pH 6.5.
4. What kind of colony inhibition do calcium propionate and sodium propionate have?
Calcium propionate and sodium propionate have a good anti-infection effect on mold, aerobic bacterium, and gram-negative bacteria, and can inhibit the production of aflatoxin, but no inhibitory effect on yeast.
5. Calcium propionate vs sodium propionate
1. the antiseptic performance of calcium propionate is the same as sodium propionate, in an acidic medium to form propionic acid and play the role of bacterial inhibition.
2. Their active ingredients are both propionic acid root
3. Calcium propionate is mainly used in bread because sodium propionate raises the pH value of bread and delays the fermentation of raw flour; sodium propionate is mostly used in pastry because the puffing of pastry uses synthetic puffing agents without the yeast development caused by the rise of pH value
4. as a feed preservative, sodium propionate is better than calcium propionate, but calcium propionate is more stable than sodium propionate.
5. When used as a feed preservative, calcium propionate can give animals a supplementary source of calcium
