Comparing:
E635: Disodium 5'-Ribonucleotides (I+G Blend)
E968: Erythritol (Zero-Calorie Fermented Polyol)
E635 (I+G) is a standardized 50/50 co-crystallized blend of disodium inosinate (E631) and disodium guanylate (E627). INS 635, ADI is Not Specified, serving as the commercial standard umami booster in global food manufacturing.
E968 (Erythritol) is a four-carbon polyol produced by microbial fermentation of glucose by Moniliella pollinis. INS 968, ADI is Not Specified, delivering 70% the sweetness of sucrose with 0.0–0.2 kcal/g, zero GI, and 90% urinary excretion avoiding digestive distress.
