摘要

BACKGROUND Quinoa porridge is becoming popular among Asian for its nutritional values; hence, it is important to understand its aroma characteristics. RESULTS Volatile compounds in porridge of 30 quinoa varieties were determined by gas chromatography-mass spectrometry combined with headspace-solid phase micro-extraction. In total, 53 volatile compounds were detected and grouped into 14 alkanals, four alcohols, seven ketones, 10 alkanes, 10 acids and esters, and eight heterocycles. The relative content of alkanes (22.97%), acids and esters (44.33%) was comparatively high, although alkanals (11.75%) may dominate the aroma. Most of the compounds were similar with respect to types and numbers, although they varied in amount, whereas 11 compounds varied significantly among different varieties. The 30 varieties could be divided into eight groups based on the concentrations of volatile compounds, although the same varieties would be divided into four groups if based on the relative odour activity values of twelve variable aroma compounds. CONCLUSION Nine compounds were identified as the main contributors to the quinoa porridge aroma, including hexanal, 1-octen-3-ol, 2-pentylfuran, nonanal, (E,E)-2,4-decadienal and 6,10-dimethyl-5,9-undecadien-2-one. Heptanal, benzeneacetaldehyde and decanal may play roles in harmonizing the overall aroma. It is also interesting to note that 6,10,14-trimethyl-2-pentadecanone, with a slightly fatty aroma, showed a high content in all varieties. (c) 2019 Society of Chemical Industry
