Answer 1

Answer: (B), (C), (D)

Prevention of decay or spoilage.

Food preservation is a process which helps in the prevention of the growth of bacteria, fungi and other microorganisms in food. Different methods of food preservation includes:
$\bullet$ Use of preservatives, air-tight packaging, smoke-drying, etc.
$\bullet$ Air-tight sealing is done to prevent the re-entry of microbes. In the absence of oxygen, growth of many microrganisms are inhibited.
$\bullet$ Properly packed food items thus prevents the decay or spoilage of food, increasing their shelf life.
