Answer 2

• The term “preservatives” refers to the functional name for a wide variety of compounds that help slow or prevent bacterial growth in a wide range of products, including foods, medicines, and personal care products. These compounds can be natural or synthetic.
• Preservatives play important roles in many products people use every day – for example, by helping prevent the growth of harmful microorganisms and protect products from spoilage or contamination.

Preservatives in Food:

• Preservatives are added to food to fight spoilage caused by bacteria, molds, fungus, and yeast.
• Preservatives can keep food fresher for longer periods of time, extending its shelf life.
• Food preservatives also are used to slow or prevent changes in color, flavor or texture and delay rancidity.

SOME FOOD PRESERVATIVES:

1. In acidic drinks like sodas and fruit juices, sodium benzoate is an antimicrobial preservative and flavoring agent that can inhibit the growth of bacteria, mold and yeast. It is found naturally in cranberries, prunes, apples and some spices. Sodium benzoate can also be used to lubricate pills and tablets for medicines.
2. Nitrites (such as sodium nitrite or sodium nitrate) are preservatives used to prevent bacteria in lunch meats and other cured meats. In a typical person’s diet, 80 percent of nitrites come from vegetables such as spinach, radishes and lettuce. Nitrites also deter botulism to some degree.
3. Sulphites such as sulphur dioxide are types of salts widely used for their preservative and antioxidant properties. In food, these are found predominantly in dried fruits and vegetables, soft drinks and alcoholic beverages.
