Question

From 100 kg milk we can obtain approx. .... kg khoya.

• A. 12
• B. 20
• C. 32
• D. 42-45

Hint:

Due to its superior fat and solid content, buffalo milk is highly preferred for khoya making, yielding around 20-22% khoya compared to cow milk which yields around 17-18%.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
Khoya (or mawa) is a traditiol Indian desiccated dairy product prepared by continuous boiling and evaporation of milk in an open pan until it reaches a semi-solid, dough-like consistency.
The yield of khoya is determined directly by the total solids content of the raw milk used.

Step 2: Detailed Explation:
The composition of milk, particularly its fat and Solid-Not-Fat (SNF) content, dictates the fil yield of the concentrated product:
- Buffalo Milk: Contains higher fat (6% to 8%) and SNF (9% to 10.5%), which results in a high yield of approximately 20% to 22% (or 20 to 22 kg of khoya per 100 kg of milk).
- Cow Milk: Typically contains lower fat (3.5% to 4.5%) and SNF (8.5% to 9%), resulting in a lower yield of about 17% to 18% (or 17 to 18 kg of khoya per 100 kg of milk).
On average, for commercial calculations and mixed milk processing, a yield of approximately 20% is standard.
Thus, from 100 kg of milk, we can obtain approximately 20 kg of khoya.

Step 3: Fil Answer:
The average yield of khoya from milk is approximately 20 kg per 100 kg of milk.
Hence, the correct option is (B).
