Question

A consumer pack of pasteurized milk kept at room temperature gives highly undesirable

organoleptic properties after several hours. Explain why?​

Answer 1

the same time as a piece of the same time

Answer 2

The reason is explained below-

• The undesirable properties develop after several hours due to improper storage of milk, which is at room temperature rather than refrigerated conditions.
• The contamination of milk after pasteurization by bacteria causes development of such properties, which could be otherwise stopped by refrigeration conditions by inhibiting bacterial growth or suspending it's activity.
• Pasteurization refers to killing of bacteria by heating at 161° F for 15 seconds or 145° F for 30 minutes and packaging it under clean conditions.
• Organoleptic properties refers to the properties that can be identified by the five sense organs.
