How are chemicals used in the food industry?

Chemical substances can play an important role in food production and preservation. Food additives can, for example, prolong the shelf life of foods; others, such as colours, can make food more attractive. Flavourings are used to make food tastier. Food supplements are used as sources of nutrition.

What are the sources of contamination in food?

Using this strategy, we have prioritized four classes of chemicals: heavy metals (i.e. lead, cadmium, and arsenic), ortho-phthalates, perchlorate, and per- and poly-fluoroalkyl substances (PFAS). These aren’t added directly to our food but can enter through production (such as during harvesting), processing, or packaging.

What makes a food product a chemical hazard?

Chemical Hazards. What is a chemical hazard? The FDA and the USDA have recognized the wide variety of chemicals used in food processing and have decided what chemicals are acceptable additives in food products and which chemical substances are strictly forbidden. These agencies have also determined acceptable levels of other chemical substances.

How are chemicals stored and handled in food?

Perhaps foremost in controlling chemical contamination are proper storage and handling practices. Chemicals should be stored separately from food products and packaging materials to avoid contamination.
