An additive or preparation used in a food product to prevent microorganisms from growing.
An agent added to fluid (as in food or medicine) that prevents the growth of microbial organisms.
Substances added to medicines or foods in prevent spoilage.
Chemicals added to food to keep it from spoiling or rotting. Preservatives are used in the processing of many foods, including baked goods, dressings, hot dogs, bologna, salami, canned vegetables, dried fruit, fruit juices, jams and jellies, relishes, teas, and processed seafood products. Although preservatives are generally safe, certain ones (notably sulfites, benzoates, parabens, nitrates, and nitrites) cause adverse reactions in susceptible individuals. Signs of a problem include headaches, hives, abdominal cramps, diarrhea, chest tightness, light-headedness, lowered blood pressure, and weakness. Rarely, sulfites may also trigger asthma attacks. An allergist can help individuals identify the preservatives to which they are sensitive. Individuals can identify and avoid foods with preservatives by reading labels on processed foods.
