E270: Lactic Acid (Biological Acidulant) vs. E967: Xylitol (Birch Sugar / Dental Caries Inhibitor)
Comparing 2 standards across 12 specifications. 12 key differences identified.
Comparing:
E270: Lactic Acid (Biological Acidulant)
E967: Xylitol (Birch Sugar / Dental Caries Inhibitor)
E270 (L-Lactic Acid) is a natural alpha-hydroxy acid produced by fermentation of carbohydrates by lactic acid bacteria (Lactobacillus). INS 270, ADI is Not Limited (Quantum Satis), imparting a smooth, mild sour taste in dairy, beers, and bakery sourdoughs.
E967 (Xylitol) is a five-carbon polyol sugar alcohol produced by hydrogenation of xylose from birch wood or corn cobs. INS 967, ADI is Not Specified, offering 100% 1:1 sugar sweetness, a cooling endothermic mouthfeel, and active inhibition of Streptococcus mutans cavity bacteria.
