Comparing 2 standards across 16 specifications. 16 key differences identified.
Comparing:
E100: Curcumin (Turmeric Yellow Color)
E415: Xanthan Gum (Pseudoplastic Hydrocolloid Thickener)
E100 (Curcumin) is a natural diarylheptanoid yellow pigment extracted from the rhizomes of turmeric (Curcuma longa). INS 100(i), ADI is 3 mg/kg bw/day, providing bright yellow-orange coloration in mustard, cheese, and curry powders.
Xanthan gum (E415) is a high-molecular-weight microbial exopolysaccharide produced by Xanthomonas campestris fermentation, renowned for extreme pseudoplastic shear-thinning rheology, freeze-thaw stability, and gluten-free dough structural binding.
