Concept:
Energy value of milk depends mainly on its fat, protein, and lactose content. Buffalo milk has higher fat content compared to cow milk, hence it provides more energy.
Step 1: Composition of buffalo milk.
Buffalo milk typically contains:
• Fat: 6–8%
• Protein: 3.5–4%
• Lactose: ~5%
Step 2: Understanding energy contribution.
• Fat gives 9 kcal/g
• Protein gives 4 kcal/g
• Lactose gives 4 kcal/g
Step 3: Estimating energy value.
Due to high fat content, buffalo milk has a higher calorific value compared to cow milk. On average:
\[
\text{Energy value} \approx 100 \text{ kcal per 100 g}
\]
Step 4: Eliminating incorrect options.
• 50 and 25 kcal are too low
• 150 kcal is too high for standard composition
Step 5: Conclusion.
Thus, the correct average energy value is 100 Caloric/100 g.
