摘    要:研究不同剂量UV-C照射处理对采后芦柑在15℃贮藏期间腐烂率及主要品质指标的影响。结果表明,1.5kJ/m2或3kJ/m2UV-C照射能有效减轻果实贮藏期间腐烂,推迟腐烂6d或12d,显著降低腐烂率。贮藏后期,1.5kJ/m2或3kJ/m2处理降低了失重率,提高了果实的可溶性固形物含量、糖酸比和VC含量,且促进了果肉中类黄酮和总酚的次生代谢合成,从而较好地保持了果实的感官品质和营养品质。1.5kJ/m2或3kJ/m2处理也有助于提高果皮中类黄酮和总酚含量。UV-C照射处理作为采后芦柑的非化学贮藏保鲜手段,具有潜在的应用前景。

Abstract:The rotting incidence,main quality parameters and flavonoid and total phenol contents were analyzed in harvested "honey" Mandarin fruit after irradiated with different doses of UV-C and stored at 15 ℃.The result showed that treatments with1.5 and 3 kJ/m2 doses of UV-C,delayed rotting infection by 6 and 12 days,and reduced rotting rate by 42.9% to 85.7% as compared to untreated fruits after 27 days of storage.1.5 and 3 kJ/m2 doses of UV-C irradiation reduced weight loss,increased SSC,SS/TA and vitamin C contents,and promoted synthesis and accumulation of flavonoid and total phenol,therefore maintained better quality and nutrition of Mandarin fruit.1.5 and 3 kJ/m2 doses of UV-C irradiation also improved the content of flavonoid and total phenol in fruit peel.These results demonstrated that UV-C treatment has the potential as a non-chemical tool for extending the shelf life of harvested Mandarin fruit.
Keywords:UV-C  Mandarins  disease resistance  quality
