Assessment of sugar content, fatty acids, free amino acids, and volatile profiles in jujube fruits at different ripening stages.
Song J, Bi J, Chen Q, Wu X, Lyu Y, Meng X. Song J, et al. Food Chem. 2019 Jan 1;270:344-352. doi: 10.1016/j.foodchem.2018.07.102. Epub 2018 Jul 17. Food Chem. 2019. PMID: 30174057
Glucose and fructose showed a decreasing tendency during ripening. As the important precursors of jujube flavor, seven fatty acids were identified, the predominant ones were C(16:0), C(16:1n7), C(18:1n9c) and C(18:2n6c); twenty-six free amino acids were quantified, …
