马尾藻提取液脱腥处理的研究

Research on the eliminating sargassum smell

马尾藻提取液具有抗肿瘤、抗凝血、降血压,提高机免疫功能等生理活性。马尾藻含有丰富的膳食纤维、褐藻淀粉、矿物质和维生素以及优质的高度不饱和脂肪酸和合理的必需氨基酸。其中必需氨基酸含量远高于海带和紫菜,其余成分与海带、紫菜相近,可以作为保健食品和药物的优质原料。由于马尾藻具有很大的海腥味使其作为功能食品和药物的优质原料,在应用上受到了一定的限止。因此,马尾藻的脱腥问题就显现出来,为此进行了这方面的处理研究。主要采用溶剂脱腥法、活性炭脱腥法和发酵脱腥法。实验表明,马尾藻最佳脱腥工艺技术是:活性炭用量2%,吸附时间为2.0h。通过对马尾藻提取液的处理,可以得到风味较好的处理液。

Sargassum is the best use of the precious marine resources, contents of protein, fat, starch of brown alga, crude fibre, minerals, vitamins and essential amino acids in sargassum. The essential amino acids in Sargassum is most higher in Laminaria and Porphra. As high as in Laminaria and Porphra contents of others precious marine presouces in 100g Sargassum. Therefore, Sargassum is a kind of precious marine presouces. The Sargassum the smell of sea- food. we studied a techneque of eliminating sargassur smells to sloved the problem. Three methods which are solvent, active carbon and fermentation were used to elininate sargassum smells. The result showed that 2. 0% active carbon solution and 2. 0h soaked time are the best techmique comditious to elininate sargassum smells. After the experiments, the sargassum is delicious from the smell of seafood.
