To exploit the nutraceutical and biomedical potential of selected seaweed-derived polymers in an economically viable way, it is necessary to analyze and understand their quality and yield fluctuations throughout the seasons. In this study, the seasonal polysaccharide yield and respective quality were evaluated in three selected seaweeds, namely the agarophyte , the carrageenophyte (both red seaweeds) and the alginophyte (brown seaweed). It was found that the agar synthesis of . did not significantly differ with the seasons (27.04% seaweed dry weight (DW)). In contrast, the carrageenan content in . varied seasonally, being synthesized in higher concentrations during the summer (18.73% DW). Meanwhile, the alginate synthesis of . exhibited a higher concentration (36.88% DW) during the winter. Therefore, there is a need to assess the threshold at which seaweed-derived polymers may have positive effects or negative impacts on human nutrition. Furthermore, this study highlights the three polymers, along with their known thresholds, at which they can have positive and/or negative health impacts. Such knowledge is key to recognizing the paradigm governing their successful deployment and related beneficial applications in humans.
为了以经济可行的方式开发选定的海藻衍生聚合物的营养保健和生物医学潜力，有必要分析和了解它们在整个季节中的质量和产量波动情况。在本研究中，对三种选定的海藻进行了季节性多糖产量和相应质量的评估，这三种海藻分别是产琼脂的海藻、产角叉菜胶的海藻（均为红藻）和产藻酸盐的海藻（褐藻）。结果发现，[具体海藻名称1]的琼脂合成在不同季节没有显著差异（占海藻干重的27.04%）。相比之下，[具体海藻名称2]中的角叉菜胶含量随季节变化，在夏季合成浓度较高（占干重的18.73%）。同时，[具体海藻名称3]的藻酸盐合成在冬季表现出较高浓度（占干重的36.88%）。因此，有必要评估海藻衍生聚合物对人类营养可能产生积极或消极影响的阈值。此外，本研究突出了这三种聚合物及其已知阈值，在这些阈值下它们可能对健康产生积极和/或消极影响。这些知识是认识到支配它们在人类中成功应用及相关有益用途的范例的关键。
