CHEMICAL FOOD PRESERVATIVES<\/span><\/h2>

Chemical food preservatives are also being used for quite some time now. They seem to be the best and the most effective for a longer shelf life and are generally full proof for the preservation purpose.<\/span><\/p>

Antimicrobial preservatives prevent degradation by bacteria. This method is the most traditional and ancient type of preserving\u2014ancient methods such as pickling and adding honey prevent microorganism growth by modifying the pH level. The most commonly used antimicrobial preservative is\u00a0lactic acid<\/a>. Common antimicrobial preservatives are presented in the table.<\/sup><\/sup><\/sup>\u00a0Nitrates<\/a>\u00a0and\u00a0nitrites<\/a>\u00a0are also antimicrobial.<\/span><\/p>

Antioxidants<\/span><\/h3>

The oxidation process spoils most food, especially those with a high fat content. Fats quickly\u00a0turn rancid<\/a>\u00a0when exposed to oxygen. Antioxidants prevent or inhibit the oxidation process. The most common antioxidant additives are\u00a0ascorbic acid<\/a>\u00a0(vitamin C<\/a>) and ascorbates.[11]<\/a><\/sup>\u00a0Thus, antioxidants are commonly added to oils, cheese, and chips.<\/span><\/p>
