Abstract:
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 Gracilaria gracilis, the carrageenophyte Calliblepharis jubata (both red seaweeds) and the alginophyte Sargassum muticum (brown seaweed). It was found that the agar synthesis of G. gracilis did not significantly differ with the seasons (27.04% seaweed dry weight (DW)). In contrast, the carrageenan content in C. jubata varied seasonally, being synthesized in higher concentrations during the summer (18.73% DW). Meanwhile, the alginate synthesis of S. muticum 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.
摘要:
以经济可行的方式开发选定海藻衍生聚合物的营养和生物医学潜力,有必要分析和了解其整个季节的质量和产量波动。在这项研究中,在三个选定的海藻中评估了季节性多糖产量和各自的质量,即龙须草,角叉菜胶(红藻)和海藻藻泥藻(褐藻)。发现甘草的琼脂合成随季节(海藻干重(DW)的27.04%)没有显着差异。相比之下,Jubata中的角叉菜胶含量随季节变化,在夏季以更高的浓度合成(18.73%DW)。同时,在冬季,S.muticum的藻酸盐合成表现出更高的浓度(DW为36.88%)。因此,有必要评估海藻衍生的聚合物可能对人类营养产生积极影响或负面影响的阈值。此外,这项研究强调了三种聚合物,连同他们已知的门槛,它们可能对健康产生积极和/或消极的影响。这些知识是认识到管理其成功部署和相关的人类有益应用的范式的关键。
