Question

_________ is the nutritious food containing fat, denatured protein, burnt lactose and minerals.

• A. Plain condensed whey
• B. Ghee-residue
• C. Sweetened condensed whey
• D. Whey paste

Hint:

Associate the term "burnt lactose" or "caramelized" with high-temperature processes like making ghee or Khoa. The byproduct of ghee production, ghee-residue, is a classic example.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
The question asks to identify a dairy byproduct based on its composition: fat, denatured protein, burnt lactose, and minerals. This composition results from a high-heat manufacturing process.
Step 2: Detailed Explanation:
Let's analyze the manufacturing process and resulting composition:
Ghee-residue: Ghee is produced by clarifying butter or cream at high temperatures (typically above 110°C) to remove water and milk solids-not-fat (MSNF). The solid particles that settle out and are filtered off constitute the ghee-residue. This residue consists of proteins that have been denatured by the high heat, lactose that has caramelized or "burnt" (causing the characteristic brown color), entrapped fat, and minerals. This perfectly matches the description in the question.
Condensed whey/Whey paste: These products are made by concentrating whey. While they contain protein, lactose, and minerals, the lactose is not typically "burnt" as the processing temperatures are lower than in ghee making.
Step 3: Final Answer:
Ghee-residue is the nutritious food byproduct that contains fat, denatured protein, burnt lactose, and minerals resulting from the high-temperature clarification of butterfat.
