    摘要:

    为了明确两种鲜切马铃薯产品的适宜加工品种。该研究以荷兰15号、希森6号、合作88、实验一号、尤金885、V7六个品种马铃薯为对象,加工千丝马铃薯丝、鲜切马铃薯片,测定出汁率、干物质含量、总酚含量、多酚氧化酶(Polyphenol Oxidase, PPO)活性等指标,进行感官评价。对指标数据进行显著性比较和相关性分析。结果表明:V7、尤金885、合作88的出汁率(10.21、10.29、10.34 mg•cm-2)均显著低于其它三个品种(12.35~14.66 mg•cm-2)(P<0.05);V7、尤金885、实验一号的干物质(17.77%、18.24%、17.33%)、淀粉(13.34%、13.78%、12.98%)、总酚含量(43.57、50.88、50.69 mg/100 g)均显著低于其它三个品种(P<0.05);V7、荷兰15号的PPO酶活性(27.89、27.81 U•g-1)显著低于其它四个品种(31.09~37.94 U•g-1)(P<0.05)。在2.0~4.0 ℃条件下,由V7、尤金885加工的鲜切马铃薯片的色泽下降程度及褐变指数均显著低于其它四个品种(P<0.05);由上述六个品种加工的千丝马铃薯丝的保鲜期分别为1、2、2、6、18、24 d,加工的鲜切马铃薯片的保鲜期分别为2、1、1、5、21、29 d。结论:千丝马铃薯丝加工的适宜品种为V7、尤金885、实验一号,鲜切马铃薯片加工的适宜品种为V7、尤金885,该结果丰富了鲜切马铃薯加工专用品种,为生产上通过品种原料的选择,缓解鲜切马铃薯加工销售中品质下降提供参考。

    Abstract:

    To identify suitable potato varieties for two fresh-cut potato products, the study investigated six potato varieties: Holland 15, Xisen 6, Cooperation 88, Experimental No. 1, Youjin 885, and V7, which were processed into shredded potato strips and fresh-cut potato slices. The juice yield rate, dry matter content, total phenolic content, polyphenol oxidase (PPO) activity, sensory quality, color, and browning index, were determined, and sensory evaluation was conducted. The results indicated that the juice yield rate of V7 (10.21 mg•cm-2), Youjin 885 (10.29 mg•cm-2), and Cooperation 88 (10.34 mg•cm-2) was significantly lower than that of the other three varieties (12.35~14.66 mg•cm-2; P<0.05). The dry matter, starch, and total phenolic content of V7 (17.77%, 13.34%, 43.57 mg/100 g), Youjin 885 (18.24%, 13.78%, 50.88 mg/100 g), and Experimental No.1 (17.33%, 12.98%, 50.69 mg/100 g) were significantly lower than the respective values of the other three varieties (P<0.05). The PPO activity of V7 (27.89 U•g-1) and Holland 15 (27.81 U•g-1) was significantly lower than that of the other four varieties (31.09~37.94 U•g-1) (P<0.05). At 2.0~4.0 ℃, the color degradation and browning index of fresh-cut V7 and Youjin 885 slices were significantly lower than those of the other four varieties (P<0.05). The fresh life of shredded potato strips processed from the six varieties was 1, 2, 2, 6, 18, 24 days, respectively, whereas the shelf life of fresh-cut potato slices was 2, 1, 1, 5, 21, 29 days, respectively. Thus, V7, Youjin 885, and Experimental No. 1 were suitable for shredded potato strip processing, whereas V7 and Youjin 885 were suitable for fresh-cut potato slice processing. The results will help in the selection of specialized varieties for fresh-cut potato processing and offer valuable insights for producers to address quality deterioration during processing and marketing through strategic raw material selection.
