ABSTRACT Date fruit contains a variety of polyphenols such as phenolic acids, flavonoid glycosides, and certain hydroxycinnamates for mediating the biological effects. It is important to analyze the degradation of chlorophylls, carotenes, and other pigments in different stages of date fruit ripening by studying the association of date fruit ripening with these pigments. The study has aimed to examine the degradation of pigments during the ripening stages of two selected date fruits. Ten different samples were gathered of Hilwa and Sullaj dates where each sample represented different ripening stages. The samples were collected during July and August, also known as the ripening months. The outcome of the study exhibited degradation of chlorophyll throughout its maturation stages, whereas the carotene degradation was comparatively low. It also demonstrated the degradation of anthocyanins in both Hilwa and Sullaj dates. The study results also implied that the absorption of ultraviolet rays appears to be the same in the rapid degradation of pigments among date fruits.

随着叶绿素、胡萝卜素和其他色素的降解,枣果实成熟

摘要枣果中含有多种多酚类物质,如酚酸、黄酮苷和某些介导生物效应的羟基肉桂酸酯。通过研究枣果成熟与这些色素的关联,分析枣果成熟不同阶段叶绿素、胡萝卜素和其他色素的降解情况具有重要意义。该研究旨在检查两种选定枣果在成熟阶段的色素降解情况。收集了 Hilwa 和 Sullaj 枣的十个不同样品,其中每个样品代表不同的成熟阶段。样品是在 7 月和 8 月收集的,也称为成熟月。研究结果显示叶绿素在其整个成熟阶段降解,而胡萝卜素降解相对较低。它还证明了 Hilwa 和 Sullaj 枣中花青素的降解。研究结果还暗示,在枣果中色素的快速降解中,紫外线的吸收似乎是相同的。
