海带物种的季节性化学特征分析历史上要么只对单一物种进行，要么数据可以追溯到60多年前。这项研究突出了详细的化学成分剖面的四种海带指状海带，海带hyperborea，海带latissima和Alaria esculenta超过14个月的时间。选择这些海带品种是因为它们具有确定的养殖潜力。它们的化学特征是确定季节变化和预测最佳收获时间。感兴趣的成分包括碳水化合物纤维素，海带多糖，藻酸盐和甘露醇以及蛋白质，灰分，金属，水分，多酚，总碳和氮含量。海带多糖和甘露醇的最高产量与灰分、蛋白质、水分和多酚的最低产量一致。这些意见的影响，使用海带作为发酵底物进行了讨论。
The seasonal chemical profiling of kelp species has historically either being carried out on only a single species or the data dates back over 60 years. This research highlights a detailed chemical composition profile of the four kelp species Laminaria digitata, Laminaria hyperborea, Saccharina latissima and Alaria esculenta over a 14-month period. These kelp species were selected due to their identified potential for cultivation. They were chemically characterised to identify seasonal variations and predict best harvest times. Components of interest included the carbohydrates cellulose, laminarin, alginate and mannitol as well as proteins, ash, metals, moisture, polyphenolics, total carbon and nitrogen content. The highest yields of lamianrin and mannitol coincided with the lowest yields in ash, protein, moisture and polyphenols. The implications of these observations for use of kelp species as a fermentation substrate are discussed.
