Abstract:

【Objective】To explore the changes of fruit quality during the ripening process of astringent Thompson Seedless grapes, and to provide a scientific basis for improving the economic benefits of the fruit for fresh eating.【Methods】The fruit sensory quality indexes and internal and external quality indexes were compared with those of normal Thompson Seedless as the control material and the fruit flavor quality was evaluated by correlation analysis and principal component analysis.【Results】The results showed that the fraction of soluble solids and solid-acid ratio in Thompson Seedless grapes increased, the fraction of titratable acid and soluble protein decreased, and the content of total phenols, flavonoids and tannins increased and then decreased as the fruit matured and became astringent. The correlation analysis showed that total phenols, flavonoids, tannins, vitamin C and soluble protein content were highly significantly and positively correlated with bitterness intensity, and soluble solids content of astringent Thompson Seedless grapes was positively correlated with sweetness intensity.【Conclusion】The astringency of Thompson Seedless grape fruit is closely related to the type and content of phenolic substances.

Key words: Thompson Seedless grape; astringency; phenolic substances; correlation analysis; principal component

摘要:

【目的】研究无核白葡萄成熟过程中果实品质涩变的变化规律,为提高鲜食无核白葡萄品质提供科学依据。【方法】以涩变无核白葡萄为试材,正常无核白葡萄为对照,对比分析果实感官指标及品质指标变化,并利用相关性和主成分分析评价果实风味品质。【结果】随着果实成熟,涩变无核白葡萄中可溶性固形物含量百分数和固酸比呈上升趋势,可滴定酸含量百分数和可溶性蛋白含量呈下降的趋势,总酚、类黄酮和单宁含量呈先上升后下降的趋势。果实的总酚、类黄酮、单宁、VC和可溶性蛋白含量均与果实苦涩感强度呈极显著正相关,涩变无核白葡萄果实的可溶性固形物含量与果实甜感强度呈正相关。【结论】涩变无核白葡萄果实的涩味与酚类物质种类、含量关系密不可分。
