Question

The products that are obtained by evaporating part of water of whole milk or fully or partly skimmed milk with or without addition of sugar are -

• A. Condensed milk
• B. A value milk
• C. Z value milk
• D. F\(_0\) value milk

Hint:

Differentiate between dairy product names and processing terms. F-value, Z-value, and D-value are all related to the mathematics of heat sterilization, not types of milk products.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
This question asks for the generic term for milk products made by concentrating milk solids through the partial removal of water.
Step 2: Detailed Explanation:
(A) Condensed milk: This is the correct generic term. It encompasses products made by evaporating water from milk. This category includes both "sweetened condensed milk" (with sugar added) and "evaporated milk" (without sugar added). The definition in the question perfectly matches the description of condensed milks.
(B) A value milk: 'A value' is not a type of milk product. It is likely a typo or an incorrect term.
(C) Z value milk: The Z-value is a term used in thermal microbiology. It represents the temperature change required to change the D-value (decimal reduction time) by a factor of 10. It is a parameter for sterilization, not a milk product.
(D) F\(_0\) value milk: The F\(_0\)-value is another term from thermal processing, representing the equivalent time in minutes at 121.1°C delivered to a product to achieve a certain level of sterility. It is a measure of the lethality of a heat process, not a product.
Step 3: Final Answer:
The correct term for products obtained by evaporating water from milk, with or without sugar, is condensed milk.
