Plant-based beverages
Industries can only use ADDITIVES approved by the governmental authorities who regulate the food and beverage sector. In Brazil, ANVISA authorizes the use of food additives within strict conditions and limits considered as safe.
Additives are used for several reasons, among them, to improve the flavor, keep the beverages freshness, texture, and appearance, in addition to ensure safety in the consumption. Additives are used in truly little quantities in relation to the whole products and are not generally used for all the companies. In a study conducted by Ital about industrialized plant-based beverages, the additives observed in the sample were:
