What are Food Preservatives?

Food preservatives are substances added to foods to extend their shelf life and prevent spoilage. They can broadly be categorised into so-called antimicrobial preservatives and antioxidant preservatives. However, many of the preservatives, like the sulphites used in wine and nitrates used in meat, serve both functions. inhibit microbial growth, slow down oxidation, and maintain the overall quality of the food. The earliest cultures actually used sugar as a preservative and it was common to store fruit in honey. Salting foods is another traditional way of early culture preserving food and pickling food was another early way for preservation.

Common Preservatives to Avoid:

Benzoic acid and its calcium, sodium or potassium salts (E210-213) are used as antibacterials and antifungals in foods such as pickled cucumbers, low sugar jams and jellies, dressings, and condiments. Antioxidant preservatives are often used in minimally processed vegetable products such as ready-to-use salads, freshly cut fruit, and fresh juices, where browning is a significant concern. Ascorbic acid (E300) and citric acid (E330) can be used to prevent browning because it inhibits a certain enzyme that in the.
