一般說明

Propionic acid (PA) is a naturally occurring carboxylic acid, which is an excellent raw material as it is stable, cheap, and safe and can even be used as a food additive.
Propionic acid is a volatile fatty acid (VFA) formed in the rumen of ruminants by bacterial fermentations.
We are committed to bringing you Greener Alternative Products, which adhere to one of the four categories of Greener Alternatives . This product is a Biobased products, showing key improvements in Green Chemistry Principles “Less Hazardous Chemical Syntheses” and “Use of Renewable Feedstock”.
