Chemical fumigation

Food spoilage is an age-old problem, and chemical preservatives have become a modern solution. But what exactly are they, and how do they keep our food safe and fresh? Preservatives fall under the umbrella of food additives, substances added to food to enhance safety, freshness, taste, texture, or appearance. The international body that evaluates the safety of these additives is the Joint FAO/WHO Expert Committee on Food Additives or JECFA. JECFA's evaluations are crucial.
