General description

Methional is the main sulfur-containing flavor compound in potatoes.

Application


  • Characterization of key aroma compounds of fried pepper sauce under different pretreatment processes.: This study identifies the key aroma compounds in fried pepper sauce, highlighting methional′s role in contributing to the sauce′s overall flavor profile. The research underscores methional′s importance in food chemistry and its potential applications in flavor enhancement and food product development (Luo et al., 2024).

The primary flavor compound in potato, methional, is synthesized from methionine by the Strecker degradation reaction. A major problem associated with potato processing is the loss of methional. Methional or its precursor, methionine, is not added back during potato processing
