ABSTRACT Biocrystallization images are formed in reaction with foods; in the course of the evaporation of the water from food extracts in presence of copper chloride, crystalline structures are formed. The structures are known to reflect food quality, such as degree of decomposition. Individual expert evaluators have suggested that crystallization images of samples from organic production contain fewer signs of decomposition and that this feature can distinguish organic foods from their conventional counterparts. To further assess the scientific merits of this methodology, a panel of nine evaluators was trained in the visual assessment of biocrystallization images and asked to rank the visual Gestalt decomposition level of encoded images of wheat extracts from i) the same production system at five different decomposition stages and ii) organic production systems vs. conventional production systems aged for the same amount of time. The panel was trained by supervised classification on the basis of defined criteria and intra- and inter-personal variation was assessed. Statistical evaluation showed that the panel was highly reliable, and that the method was appropriate for ranking biocrystallization images of five different decomposition levels. Furthermore, images of samples from organic or conventional production systems could be distinguished with high agreement according to their Gestalt decomposition level with fewer signs of decomposition in the images of organic samples. The rank order between the organic systems vs. the conventional systems was significant.

生物结晶图像视觉格式塔评估高级小组培训：对来自不同提取物分解阶段和不同生产系统的小麦样品进行排序

摘要 生物结晶图像是与食物反应形成的；在氯化铜存在的情况下，从食品提取物中蒸发水分的过程中，会形成晶体结构。已知结构反映食品质量，例如分解程度。个别专家评估员建议，有机生产样品的结晶图像包含较少的分解迹象，这一特征可以将有机食品与其传统对应物区分开来。为了进一步评估这种方法的科学价值，一个由 9 名评估员组成的小组接受了生物结晶图像视觉评估的培训，并要求对来自 i) 五个不同分解阶段的相同生产系统和 ii) 有机生产系统与传统生产系统的小麦提取物编码图像的视觉格式塔分解水平进行排名生产系统老化时间相同。该小组根据定义的标准通过监督分类进行培训，并评估了人与人之间的差异。统计评估表明该面板高度可靠，并且该方法适用于对五种不同分解水平的生物结晶图像进行排序。此外，来自有机或传统生产系统的样品图像可以根据其格式塔分解水平以高度一致的方式进行区分，有机样品图像中的分解迹象较少。有机系统与传统系统之间的等级顺序是显着的。
