摘要
以福建省平潭县主要栽培的坛紫菜品种和来自平潭县不同海域的野生坛紫菜为材料,测定不同样品主要品质性状等指标;同时对不同样品进行了活体吸收光谱的检测.结果显示:3种性状在不同紫菜样品中存在着显著的差异,而且不同样品之间的活体吸收光谱也存在明显的不同.野生坛紫菜NH蛋白质含量最高,每100g干紫菜中含量可达43.49±1.29g,而未经选育的坛紫菜DXY仅为24.85±2.0g;叶绿素含量最高的为优良品种GL1,最低的为野生坛紫菜JJS.藻胆蛋白含量与总蛋白含量呈正相关,其含量最高的仍为野生坛紫菜NH(4.488g/100g).对于每一个紫菜样品,藻红蛋白含量都大于藻蓝蛋白,藻蓝蛋白含量大于别藻蓝蛋白.
The content of the main characters in the mostly cultured Porphyra haitanensis and the wild P.haitanesis in different islands collected in Pingtan County were determined.At the same time in vivo absorption spectra of different samples were observed. The results showed that three of characters were distinctly different in different samples of P.haitanensis.But in vivo absorption spectra of different samples were obviously different.The wild P.haitanesis NH had the highest content of the protein (43.49±1.29 g/100 g),but the cultured P.haitanensis DXY which was not selected was only 24.85±2.0 g/100 g;the content of chlorophyll in fine cultured P.haitanensis GL1 was the highest,but the content of chlorophyll in wild P.haitanesis JJS was the lowest.Their total amount of phycobiliprotein had a positive correlation (r=0.6201) with their total amount of protein in different P.haitanensis and the wild P.haitanesis NH had also the highest content of phycobiliprotein.(4.488 g/100 g).For the every P.haitanensis,its phycoerythrin content was higher than its phycocyanin content,but its allophycocyanin content was lower than its phycocyanin content.
