E330: Citric Acid (Universal Acidulant / Chelator)
E471: Mono- & Diglycerides of Fatty Acids (Bread Softener)
E330 (Citric Acid) is a tricarboxylic organic acid produced by industrial fermentation of Aspergillus niger on carbohydrate substrates. INS 330, ADI is Not Limited (Quantum Satis), the single most widely used acidulant, flavor enhancer, and metal chelator on Earth.
E471 is an authorized food emulsifier composed of glycerol esterified with one or two fatty acid chains (glycerol monostearate / monooleate). INS 471, ADI is Not Limited (Quantum Satis), globally recognized as the ultimate crumb softener and amylose complexing agent in bakery.
