- Different Carbon 14 test results: Fermented propionate can pass the C14 test to prove it is 100% natural while chemical propionate cannot.
- Different production materials: Biologically fermented propionate is prepared from natural raw materials, and chemically synthesized propionate raw materials are extracted from petrochemicals.
- Different production processes: Biologically fermented propionate is produced by anaerobic metabolism at room temperature and pressure, and chemically synthesized propionate is produced and processed by high temperature and high pressure chemical synthesis.
- Different production capacity consumption: Biologically fermented propionate undergoes liquid deep fermentation, which is more energy-saving and environmentally friendly. The production process of chemically synthesized calcium propionate is energy-consuming and highly polluting.
