The Chemical Analysis of S.kjellmanianum in Shandong Peninsula
Sargassum kjellmanianumianum was collected in Yangma Island of Yantai, Long Island and Qingdao, respectively. Chemical components analysis was conducted. The results show that proteins, carbohydrates and mineral elements are the main nutrition composition of the S.kjellmanianumianum in the three areas. Among them the crude protein content is in scope for 11.70% to 15.09%. The total sugar content is not high, occupying only 16.47% to 26.42% of the dry weight. The content of the mineral element of K, Na, Ca, Mg, Fe is very high. Fatty acids of C16 and C18 are predominant fatty acids, accounting for about half of the total fatty acids. Amino acid content ranges from 13.08% to 15.19%, and the content of the aspartic acid, glutamic acid, valine and alanine is rich, and each is higher than 1%. There are a variety of essential nutrients of human body in the Sargassum kjellmanianumianum, which are valuable to be researched and exploited.
