Study Notes
Food Additives
- A food additive is any substance that becomes incorporated into food during production, packaging, transportation, or storage.
- There are two types of food additives: direct (intentional) and indirect (unintentional).
- Direct food additives are added to foods for various reasons, such as:
- Making food easier to process
- Enhancing nutrition
- Improving safety by limiting bacterial growth
- Preventing undesirable chemical changes
- Providing flavor, color, or texture
- Examples of direct food additives include:
- Preservatives (e.g., ascorbic acid, sodium benzoate)
- Sweeteners (e.g., sucrose, aspartame)
- Flavors and spices (e.g., natural flavorings, artificial flavorings)
- Nutrients (e.g., thiamin hydrochloride, folic acid)
- Emulsifiers (e.g., soy lecithin, mono- and diglycerides)
- Stabilizers, thickeners, and binders (e.g., gelatin, pectin)
- Color additives (e.g., FD&C Blue No. 1, beta-carotene)
Food Safety Legislation: GRAS and Delaney Clause
- The Food Additives Amendment of 1958 established the GRAS (Generally Recognized as Safe) list, which excludes certain substances from being defined as food additives.
- Substances on the GRAS list are considered safe for their intended use and do not require testing or FDA approval.
- The Delaney Clause states that food manufacturers cannot add a new compound that causes cancer at any level of intake.
- The FDA sets safety standards for food additives, considering factors such as chemical composition, intake levels, and potential health effects.
Unintentional Food Additives
- Indirect food additives can enter food during packaging, transportation, or storage and have no purpose.
- Examples of unintended food additives include:
- Compounds from food wrappers or containers
- Pesticide residues
- Mold toxins
- Industrial chemicals
- The FDA regulates and sets guidelines for unavoidable, naturally occurring substances in foods, such as dirt and insect parts.
Pesticides
- A pesticide is any substance used to control or kill unwanted insects, weeds, rodents, fungi, or other harmful organisms.
- Pesticides can leave small amounts of residues on or in treated crops, even when applied correctly.
- The EPA regulates the proper use of pesticides, sets pesticide tolerances, and promotes nonchemical pest management techniques.
- Integrated pest management (IPM) involves using a variety of methods to control pests while limiting environmental damage.
- Biologically based pesticides, such as pheromones and viruses, are becoming increasingly popular among farmers.
Safety of Pesticides
- Pesticides have both beneficial and unwanted effects, and their potential harmful effects depend on the particular chemical, concentration, and exposure.
- Pesticide exposure has been linked to an increased risk of certain cancers, including multiple myeloma, brain tumors, and prostate, lip, and thyroid cancers.
- Environmental health experts continue to monitor the effects of pesticides on humans.
