Low 4-MEI Caramel Colours Answer California Rules and Retailer Standards
California Proposition 65 requires warnings for foods that expose consumers to more than 29 micrograms of 4-MEI a day, and beverage brands reformulated years ago to avoid labels. Suppliers now offer Class I and lower-4-MEI Class IV colours, plus plant-based alternatives such as vegetable carbon and anthocyanin systems. Compliant colours cost 5% to 15% more, and brands need new stability testing across acidic drinks and sauces. Suppliers with low-4-MEI processes and testing data win specification with global brands and retailers that publish colour standards. Reformulation usually takes nine months or longer.
