Food Science and Technology QUESTION #5920
Question 1
Which statement correctly distinguishes 'sweet whey' from 'acid whey'?
  • Sweet whey has higher fat content; acid whey has lower fat
  • Sweet whey (\(\text{pH}\;5.9\text{–}6.3\)) comes from rennet-coagulated cheese; acid whey (\(\text{pH} < 5\)) comes from acid-coagulated products like cottage cheese or paneer✔️
  • Sweet whey contains more lactose; acid whey contains more casein
  • Sweet whey is from buffalo milk; acid whey is from cow milk
Correct Answer Explanation
Sweet whey (\(\text{pH} \approx 5.9\text{–}6.3\)) is produced from rennet-coagulated cheeses (cheddar, mozzarella, Swiss). Acid whey (\(\text{pH} \approx 4.3\text{–}4.6\)) results from acid coagulation (cottage cheese, paneer, quark). Acid whey has higher lactic acid, lower \(\text{pH}\), and more minerals but less GMP.
