通过贮藏原料延长罐藏白桃制品加工期的可行性研究

    Feasibility study on prolonging throughput of canned white peach by fruit material storage

    • 摘要: 研究了“大久保”和“京玉”桃果实贮藏不同时间后其罐藏制品的感官品质、理化指标及原料利用率的变化规律。试验结果表明:“大久保”桃果实在贮藏45 d内,罐藏制品的色泽改善、耐煮性增强,综合品质得到改善,原料利用率在贮藏30 d时为对照的151.47%;“京玉”桃果实贮藏15 d时其罐藏制品色泽有了显著改善,而硬度极显著地增加;“大久保”和“京玉”桃果实原料分别贮藏30 d和15 d时,进行罐藏制品加工具有扩大化生产的可行性。

       

      Abstract: In this paper, sensory quality, some physical and chemical indexes and material use efficiencies of canned peach using different storage periods of ‘Okubao’(Amygdalus persica cv. Okubao) and ‘Jingyu’(A. p.cv. Jingyu) peach fruits as material were studied. The results showed that the appearance, firmness and integrated quality of canned ‘Okubao’ peach were improved when stored for 15~45 d, material use efficiencies were 151.47% of the control at 30th d. The appearance and firmness of canned ‘Jingyu’ peach were significantly improved at 15th d. The present study suggested the feasibility of canning ‘Okubao’ and ‘Jingyu’ peach fruits stored for 30 and 15 d, respectively, which means hopeful expanded production.
