摘要:

阳光1号柑橘是以红美人柑橘为母本、春香柑橘为父本杂交选育的新品种,具有易剥皮、果肉细嫩、风味浓郁等优良特性。阳光1号虽然耐贮藏,但目前尚无关于其贮藏期间果实品质变化的研究。本文以室温(10~15 ℃)和低温(4~6 ℃)条件下贮藏的阳光1号柑橘为材料,测定其果实品质指标,贮藏周期120 d。结果表明,贮藏期间果实单果重、果实横径及可滴定酸含量持续下降,果皮重、果形指数、出汁率、可溶性固形物及维生素C含量呈先升高后降低的趋势,糖酸比与色差指数持续升高,可食率先降低后趋于稳定。贮藏前期(0~90 d),大部分指标在2种温度下无显著差异。相关分析显示,果实大小指标(单果重、果实纵径、果实横径)与可滴定酸含量呈极显著(p<0.01)正相关。糖酸比、色差指数分别与单果重、果实横径、果实纵径、可滴定酸含量呈显著(p<0.05)或极显著负相关。综合分析表明,室温贮藏0和30 d果实风味较佳,低温贮藏60 d果实综合品质最优。本研究结果为阳光1号的推广应用以及货架期的确定提供了理论依据。

Abstract:

Yangguang 1 citrus is a new hybrid variety developed from a cross between the maternal parent Hongmeiren and the paternal parent Chunxiang. It features excellent traits such as easy peeling,tender flesh,and rich flavor. Although Yangguang 1 exhibits good storability,there is currently no reported research on the changes in its fruit quality during storage. This study used Yangguang 1 citrus fruit stored under room temperature(10-15 ℃)and low temperature(4-6 ℃)conditions as materials,periodically measuring fruit quality indicators,storage periods were 120 d. The results showed that during storage,the single fruit weight,transverse diameter,and titratable acid content continuously decreased. Fruit peel weight,fruit shape index,juice yield,soluble solids content,and vitamin C content initially increased and then decreased. The sugar-acid ratio and color index continuously increased. The edible rate first decreased and then stabilized. During the storage for 0-90 d,most indicators showed no significant difference between the two temperature conditions. Correlation analysis revealed that fruit size indicators(single fruit weight,longitudinal diameter,transverse diameter)were highly significantly(p<0.01)positively correlated with titratable acid content. Sugar-acid ratio and color difference index were significantly(p<0.05)or highly significantly negatively correlated with single fruit weight,transverse diameter,longitudinal diameter and titratable acid content. Comprehensive evaluation indicated that fruit flavor was best at 0 day and 30 days of room temperature storage,while the overall fruit quality was optimal at 60 days of low-temperature storage. These findings provide a theoretical basis for the promotion and application of Yangguang1 and the determination of its shelf-life.
