Food Science and Technology QUESTION #5879
Question 1
Whey proteins are nutritionally superior to casein primarily because they:
  • Have a higher total protein content in milk
  • Contain more essential amino acids and higher biological value \((\text{BV} \approx 100)\)✔️
  • Are heat stable and resistant to digestion
  • Contain more phosphorus and calcium
Correct Answer Explanation
Whey proteins (\(\beta\)-lactoglobulin and \(\alpha\)-lactalbumin) have a biological value approaching \(100\) and a PDCAAS of \(1.0\), reflecting their excellent essential amino acid profile including high leucine, cysteine, and BCAAs.
