That is the question.
Some consumers are concerned about preservatives and additives used in processed food.
Additives have been used since antiquity either to improve food preparation or to preserve food. Salt was used to cure meat in 3,000 B.C., and bread leavened by yeast or chemicals has been popular for millennia. The U.S. Food, Drug and Cosmetic Act defines a food additive as any substance that becomes a component of food or affects the characteristics of a food. By legal definition, sugar and spices, as well as leavening agents are food additives. More than 75 percent of food additives are used to impart flavor.
