← HistoryWhich consequence arises when the alkaline concentration in ancient Mesoamerican nixtamalization becomes excessively high?
A)Reduced starch gelatinization occurs
B)Increased aflatoxin contamination risk
C)Lysine degradation is accelerated✓
D)Phytic acid bioavailability increases
💡 Explanation
Excessive alkalinity during nixtamalization accelerates Maillard reactions, leading to *lysine degradation* because the elevated base promotes a Strecker degradation. Therefore, nutritional value decreases, rather than enhanced starch gelatinization under controlled conditions.
