中文摘要: 以沙果为原料,分析沙果不同成熟期[绿熟期(green mature,GM)、白熟期(white mature,WM)、半黄半红期(half mature,HM)和红熟期(red mature,RM)]对水果品质(硬度、可溶性固形物含量、可滴定酸含量、抗坏血酸含量)、抗氧化成分及活性(总酚含量、总黄酮含量、DPPH 自由基和ABTS+自由基清除率以及铁还原能力)的影响。结果表明:在沙果成熟的过程中,可溶性固形物含量增加,可滴定酸含量降低。在半黄半红期,果皮中总酚含量及抗氧化活性最高,而果肉在白熟期时,总酚含量和抗氧化活性最高。综合考虑沙果品质和抗氧化活性以及货架期因素,沙果可在白熟期采摘,半黄半红期为最佳的食用时期。
Abstract:Using crabapple as raw materials, the fruit quality(hardness, soluble solids, titrable acids, and ascorbic acid) and the antioxidant components and activities [total phenols, total flavonoids, DPPH and ABTS+ free radical scavenging rates, and ferric reducing antioxidant power (FRAP)] of crabapple at the green mature (GM), white mature (WM), half mature (HM), and red mature (RM) stages were analyzed. The results showed that the soluble solid content increased and the titratable acid content decreased during fruit ripening. The total phenol content and antioxidant activity in the peel were the highest at the HM stage, while the total phenol content and antioxidant activity in the flesh were the highest at the WM stage. Considering the quality, antioxidant activity, and shelf life, crabapple fruits can be picked at the WM stage, and the HM stage was the best for fresh eating.
