Abstract

‘Queen Nina’ is a popular grape variety, but the fruit flavor profile and its evolution and regulatory mechanism remain unclear. The flavor profile of ‘Queen Nina’ was systematically investigated by analyzing the soluble sugars, organic acids, free amino acids, and aroma volatiles at 6 different stages. A total of 55 aroma volatiles were identified, with esters being the predominant volatiles in mature berries. The flavor profile of ‘Queen Nina’ was elucidated by constructing a flavor radar chart based on the results of OAV, which identified 5 volatiles as reliable indicators of berries ripening. Additionally, we identified 29 genes associated with esters metabolism and reported for the first time the involvement of the CXE gene family in aroma esters decomposition in grapes. The results contribute to a more comprehensive understanding of the dynamics underlying the flavor profile of ‘Queen Nina’, thereby providing novel insights into enhancing the grape aroma.

期刊介绍： Food Chemistry: Molecular Sciences is one of three companion journals to the highly respected Food Chemistry. Food Chemistry: Molecular Sciences is an open access journal publishing research advancing the theory and practice of molecular sciences of foods. The types of articles considered are original research articles, analytical methods, comprehensive reviews and commentaries. Topics include: Molecular sciences relating to major and minor components of food (nutrients and bioactives) and their physiological, sensory, flavour, and microbiological aspects; data must be sufficient to demonstrate relevance to foods and as consumed by humans Changes in molecular composition or structure in foods occurring or induced during growth, distribution and processing (industrial or domestic) or as a result of human metabolism Quality, safety, authenticity and traceability of foods and packaging materials Valorisation of food waste arising from processing and exploitation of by-products Molecular sciences of additives, contaminants including agro-chemicals, together with their metabolism, food fate and benefit: risk to human health Novel analytical and computational (bioinformatics) methods related to foods as consumed, nutrients and bioactives, sensory, metabolic fate, and origins of foods. Articles must be concerned with new or novel methods or novel uses and must be applied to real-world samples to demonstrate robustness. Those dealing with significant improvements to existing methods or foods and commodities from different regions, and re-use of existing data will be considered, provided authors can establish sufficient originality.
