摘要:

【目的】探索1-甲基环丙烯(1-methylcyclopropene,1-MCP)与气调处理对‘御皇李’贮藏保鲜效果及果实内在品质维持的影响,明确‘御皇李’贮藏保鲜调控策略,为其产业化贮藏保鲜提供理论依据与技术参考。【方法】以‘御皇李’为试材,设置1.0 µL·L-11-MCP、3% O2+1% CO2、3% O2+5% CO2气调(controlled atmosphere,CA)贮藏和普通冷藏对照(CK)4组贮藏处理,于贮藏0、30、60和90 d,采用色差仪、质构仪、气相色谱仪、高效液相色谱仪、气质联用仪等设备,测定果皮色泽、果实质地、糖酸组分、呼吸强度、果实香气等外观品质和内在品质指标。【结果】与普通冷藏相比,气调及1-MCP处理均能延缓果实硬度及可滴定酸含量下降,保持良好的可溶性固形物、维生素C(Vc)和多酚含量,降低果实呼吸强度,减缓果实内聚性、果肉弹性、果肉胶黏性、咀嚼性、破裂力、破裂位移、屈服力及屈服位移的下降趋势,较好保持果肉质地。1-MCP和气调处理均能在一定程度上抑制果实糖酸组分的分解,贮藏60 d时果实酸度保持较好。各处理果皮色差参数L*、a*、b*、c*值在贮藏期间整体呈下降趋势,其中CK下降最快,3% O2+5% CO2气调处理次之,3% O2+1% CO2气调处理较缓,1-MCP处理最优,显著抑制了果实褐变与色泽暗沉(P<0.05)。贮藏60 d时,1-MCP处理的保鲜效果最显著,其次为3% O2+1% CO2与3% O2+5% CO2处理,CK果实品质下降最明显;此时‘御皇李’果实风味物质以醛类、醇类和酯类为主,其中反式-2-己烯醛和己醛相对含量合计约占84%。随着贮藏时间延长,气调与1-MCP处理组醛类和醇类相对含量下降,酯类物质相对含量上升。【结论】1-MCP(1.0 µL·L-1)和3% O2+1% CO2气调贮藏均可有效维持‘御皇李’冷藏期间的品质,但1-MCP处理在保持果实综合品质(质地、色泽、风味)方面表现更全面,其中冷藏60 d时果实外观和内在品质保持最佳。

Abstract:

【Objective】This study aimed to investigate the effects of 1-methylcyclopropene (1-MCP) and controlled atmosphere (CA) storage on the preservation and internal quality of YuHuangli plums, to identify the optimal storage strategies, so as to provide the theoretical and technical references for industrial-scale storage.【Method】YuHuangli plums were subjected to four storage treatments: 1.0 µL·L-1 1-MCP, CA storage with 3% O2 + 1% CO2, CA storage with 3% O2 + 5% CO2, and normal cold storage as a control (CK). Fruit samples were analyzed at 0, 30, 60, and 90 days of storage. External and internal quality indices—including peel color, texture, sugar-acid composition, respiration intensity, and aroma-were measured using a colorimeter, texture analyzer, gas chromatograph, high-performance liquid chromatograph, and gas chromatography-mass spectrometer.【Result】Compared with CK, both 1-MCP and CA treatments delayed the decline in fruit firmness and titratable acidity, maintained higher levels of soluble solids, vitamin C, and polyphenols, reduced respiration rates, and slowed the reduction of cohesiveness, springiness, gumminess, chewiness, rupture force, rupture deformation, yield force, and yield deformation, thus better preserving fruit texture. Both treatments also partially inhibited the degradation of sugar-acid components, with acidity being better maintained after 60 days. Peel color parameters (L*, a*, b*, and C*) declined during storage, with the fastest decrease under CK, followed by 3% O2 + 5% CO2, then 3% O2 + 1% CO2, and the slowest under 1-MCP treatment, significantly suppressing browning and darkening (P<0.05). After 60 days, 1-MCP exhibited the most pronounced preservation effect, followed by 3% O2 + 1% CO2 and 3% O2 + 5% CO2, while CK showed the greatest quality deterioration. At this stage, the flavor profile of YuHuangli plum was dominated by aldehydes, alcohols, and esters, with trans-2-hexenal and hexanal accounting for about 84% of the total relative content. Over time, the relative content of aldehydes and alcohols decreased in the 1-MCP and CA groups, whereas esters increased.【Conclusion】Both 1-MCP (1.0 µL·L-1) and CA storage (3% O2 + 1% CO2) effectively preserved the quality of ‘YuHuangli’ plums during cold storage. Among them, 1-MCP provided the most comprehensive maintenance of overall fruit quality—including texture, color, and flavor—with the optimal preservation observed after 60 days.
