Q110: Given below are two statements, one is labelled as Assertion... - Post-Harvest Technology of Vegetable Crops - Post Harvest Management- ICAR JRF/SRF 2024 | Agrigyan

• Assertion (A) is True: In commercial vegetable freezing and dehydration, the complete inactivation of the peroxidase enzyme is the universally accepted biochemical index confirming blanching adequacy.
• Reason (R) is True and Explains (A): Peroxidase is the most heat-stable enzyme among all endogenous enzymes present in fruits and vegetables. If thermal treatment is intense enough to denature peroxidase, all other deleterious enzymes (catalase, polyphenol oxidase, lipoxygenase) and vegetative pathogens will have been completely inactivated.
• Conclusion: Both (A) and (R) are true, and (R) is the correct explanation of (A) (Option 1).

Correct option: (1) Both (A) and (R) are true and (R) is the correct explanation of (A)
