Answer:
Preservatives help extend the quality and safety of food far beyond what is capable without their use. Food preservation is generally defined as any act or addition that inhibits undesired bacterial growth or chemical changes. You likely practice food preservation on a daily basis without even knowing it. Preservatives can also have nutritive roles as well. Take ascorbic acid as an example; it is a powerful antioxidant and antimicrobial compound that is added to everything from bacon to carbonated drinks. One of the biggest benefits of preservatives is increased food safety. Many natural and living microorganisms are capable of producing toxins that can increase the risk of many diseases. Ask yourself this: have you heard of a friend getting ill from botulinum poisoning in sausage? What about catching tuberculosis from drinking milk? It may sound ridiculous, but these were both deadly diseases at one time. Food preservation is such an integral part of why these risks are mitigated. Nitrites are added to cured meats to stop Clostridium botulinum growth, and pasteurization has effectively addressed the presence of Mycobacterium tuberculosis in fluid milk.
