Question

State the difference between a) decay and putrefaction b)pasteurization and sterilisation

Answer 1

putrefaction is one stage in the decomposition of the body of a dead animal; it can be described as the decomposition of proteins, which results in the eventual breakdown of cohesion between tissues and liquification of most organs. 

Decomposition is the process by which organic material is broken down into simpler forms of matter. The process is essential for recycling the finite matter that occupies physical space in the biome. Bodies of living organisms begin to decompose shortly after death. Although no two organisms decompose in the same way, they all undergo the same sequential stages of decomposition. The science which studies decomposition is generally referred to as taphonomy from the Greek word taphos, meaning tomb.
 

Sterilization: Sterilization is any process that eliminates all forms of life and other biological agents present in a surface, food, packaging material, a volume of fluid, medication, instruments or in a biological culture media.

Pasteurization: Pasteurization is a process that kills pathogenic bacteria in liquid food.

Sterilization: Shelf-life is longer than pasteurized products or has extended shelf-life.

Pasteurization: Pasteurized products have a shorter shelf life compared to sterilized product

Sterilization: Sterilization eliminates all forms of microorganisms (Spoilage and pathogenic microbes) and their spores.

Pasteurization: Pasteurization only eliminates pathogenic microorganisms. So pasteurized products should be stored under refrigerated conditions. If the product is exposed to the microbial growth desirable environment conditions pasteurized food may be contaminated.
