ABSTRACT

A novel method for assessing antimicrobial (AMP), colour retainment (CRP) and slice healing properties (SHP) of cucumber fruit (Cucumis sativus L.) was presented. The fruit was sliced in 15 mm slices, foliated in transparent plastic and placed at 23.5°C in a heating cabinet for 14 days. Subsequently, AMP and CRP were scored on scales of 1–9 and 1–7, respectively, with units of one. SHP was scored as an ‘on/off’ criterion with scores of 1 or 9 (1, the sample broke at one or more slice interfaces when manually held in horizontal position; 9, the slices did not break at any point). Samples with maximum scores for AMP and SHP were re-tested after additional period(s) of 7 days. The data were assessed by linear regression and analyses of variance. Approximately 300 cucumber samples, primarily from Denmark, Poland and Slovenia, were examined. Eight cultivation and production factors (cultivation system, production scale, growing medium, pre-laboratory conditions, fruit morphology, calendar week, producer, country) were examined. The results indicated that samples from the organic and biodynamic producers, from small scale production units, and from soil-based production systems had superior quality characteristics as measured by these parameters. The introduction of the parameter SHP represented an approach to measure vitality, complementing the approaches of measuring degradation represented by the parameters AMP and CRP. With respect to a practical application, the predictive value of the method should be tested relative to the ability of the sample to maintain turgor and taste under post-harvest conditions.

摘要

一种评估黄瓜果实 ( Cucumis sativus ) 抗菌 (AMP)、保色 (CRP) 和切片愈合特性 (SHP) 的新方法L.) 提出。将水果切成 15 毫米的薄片，在透明塑料中形成叶子，然后在 23.5°C 的加热柜中放置 14 天。随后，AMP 和 CRP 的评分分别为 1-9 和 1-7，单位为 1。SHP 评分为“开/关”标准，得分为 1 或 9（1，当手动保持在水平位置时，样品在一个或多个切片界面处破裂；9，切片在任何点都没有破裂）。AMP 和 SHP 得分最高的样品在 7 天的额外时间后重新测试。通过线性回归和方差分析评估数据。检查了大约 300 个黄瓜样品，主要来自丹麦、波兰和斯洛文尼亚。八种栽培生产要素（栽培体系、生产规模、生长介质、前期实验室条件、果实形态、日历周、生产商、国家）进行了检查。结果表明，来自有机和生物动力生产者、小规模生产单位和基于土壤的生产系统的样品具有通过这些参数衡量的优良质量特征。参数 SHP 的引入代表了一种衡量活力的方法，补充了以参数 AMP 和 CRP 为代表的衡量退化的方法。在实际应用中，该方法的预测值应根据样品在收获后条件下保持饱满度和味道的能力进行测试。以这些参数衡量，基于土壤的生产系统具有卓越的质量特性。参数 SHP 的引入代表了一种衡量活力的方法，补充了以参数 AMP 和 CRP 为代表的衡量退化的方法。在实际应用中，该方法的预测值应根据样品在收获后条件下保持饱满度和味道的能力进行测试。以这些参数衡量，基于土壤的生产系统具有卓越的质量特性。参数 SHP 的引入代表了一种衡量活力的方法，补充了以参数 AMP 和 CRP 为代表的衡量退化的方法。在实际应用中，该方法的预测值应根据样品在收获后条件下保持饱满度和味道的能力进行测试。
