A critical sector of the food industry is manufacturers of flavors. Flavors, whether artificial or natural, are components of nearly every product. Flavor production is highly complex and uses raw materials from every imaginable source. Some common kosher sensitive ingredients used in flavors are fusel oil (which may be extracted from grape juice), glycerin and castorium (a beaver extract). Since the ingredient declaration never includes a breakdown of ingredients used in flavors, food items containing natural or artificial flavors require reliable supervision.
