question 86:
in refrigerating fresh product, a combination of low temperature & high humidity helps to...
a. reduce water lost by transpiration
b. slow down maturity
c. reduce microbial growth and development
d. all of the above
e. none of the above

Explanation:

To solve this, we analyze each option:

• Option A: Low temp and high humidity in refrigeration reduces water loss via transpiration (plants lose water, high humidity reduces this).
• Option B: Low temperature slows down metabolic processes, thus slowing maturity (ripening, aging of fresh products).
• Option C: Low temperature inhibits microbial growth (most microbes grow slower in cold), and high humidity alone doesn't promote microbial growth here; combined, low temp reduces microbial development.
• So, all (A, B, C) are effects of low temp + high humidity in refrigerating fresh products.

Answer:

D. all of the above
