History

Which 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.
