FOOD PRESERVATIVES Meaning and
Definition
-
Food Preservatives are natural or synthetic substances that are added to food products to prolong their shelf life and prevent spoilage caused by microbial growth, enzymatic reactions, or chemical deterioration. These substances act by inhibiting the growth of spoilage-causing bacteria, yeasts, molds, or other microorganisms, thus maintaining the safety, quality, and freshness of the food.
There are various types of food preservatives, including antimicrobial agents, antioxidants, and chelating agents. Antimicrobial agents, such as benzoates, sulfites, or nitrates, prevent or slow down the growth of bacteria, yeasts, or molds that can cause food spoilage or illness. Antioxidants, such as butylated hydroxyanisole (BHA) or ascorbic acid (vitamin C), help prevent the oxidation of fats and oils in food, extending their shelf life and preventing the development of off-flavors or rancidity. Chelating agents, such as EDTA or citric acid, bind with metal ions that can catalyze chemical reactions leading to food deterioration.
While food preservatives play a crucial role in maintaining food safety and reducing food waste, their use needs to be regulated to ensure their safety and prevent potential adverse health effects. Regulatory bodies, such as the Food and Drug Administration (FDA) or European Food Safety Authority (EFSA), establish Maximum Residue Limits (MRLs) or Acceptable Daily Intakes (ADIs) for preservatives to ensure that they are used at safe levels. Consumers are encouraged to read food labels and make informed choices about the products they consume, considering their individual tolerance and preferences regarding food preservatives.
