E334: L-Tartaric Acid (Wine & Baking Acidulant)
E950: Acesulfame Potassium (Ace-K / 200x Sweetener)
E334 (L(+)-Tartaric Acid) is a dicarboxylic organic acid recovered as potassium bitartrate by-product from wine barrels. INS 334, ADI has historically been set at up to 20 mg/kg bw/day by JECFA, delivering a sharp, lingering tartness in candies, soft drinks, and baking powders.
E950 (Acesulfame K / Ace-K) is a calorie-free, heat-stable synthetic potassium salt sweetener approximately 200 times sweeter than sucrose. INS 950, ADI is 9 mg/kg bw/day, famous for blending with sucralose and aspartame to produce sugar-identical taste curves.
