Abstract

A growing concern on the accumulation and disposal of fish processing discards and environmental degradation induces a profound attraction on the development of valuable byproducts for human purposes. Gelatin was isolated from Siboga squid ( Doryteuthiis sibogae ) skin through cold maturation process and its physico-chemical as well as structural properties viz . Water Holding Capacity (WHC), emulsifying capacity, emulsifying stability and viscosity were analyzed. The alkaline treatment of skin yielded 7.5 % gelatin powder. Extracted gelatin was characterized using UV-visible spectroscopy, 1 H NMR, FT-IR and Raman analyses. Based on FT-IR and Raman fingerprints, peak located at 1664 cm -1 (C=O stretch Amide I band) could be inferred that secondary structure of proteins as well as coiled structure of gelatin. Topographic analysis by AFM showed presence of aggregates of the polymer. The results suggest that the Siboga squid gelatin is an alternative source of gelatin and its potential applicability at industrial scale.

鱿鱼工业加工废渣的提取及明胶的理化性质研究

对鱼类加工废料的积累和处置以及环境退化的日益关注，使人们对开发供人类使用的有价值的副产品产生了深刻的吸引力。采用冷熟法从鱿鱼皮中分离出明胶，并对其理化性质和结构性质进行了研究。分析了保水能力、乳化能力、乳化稳定性和粘度。皮肤的碱性处理得到7.5%的明胶粉。用紫外可见光谱、1h NMR、FT-IR和拉曼光谱对提取的明胶进行了表征。基于FT-IR和拉曼指纹图谱，峰位于1664 cm -1处(C=O stretch Amide I波段)，可以推断蛋白质的二级结构以及明胶的卷曲结构。原子力显微镜的形貌分析显示聚合物聚集物的存在。结果表明，锡博加鱿鱼明胶是明胶的一种替代来源，具有工业规模应用的潜力。

期刊介绍： Started in 1972, this multi-disciplinary journal publishes full papers and short communications. The Indian Journal of Geo-Marine Sciences, issued monthly, is devoted to the publication of communications relating to various facets of research in (i) Marine sciences including marine engineering and marine pollution; (ii) Climate change & (iii) Geosciences i.e. geology, geography and geophysics. IJMS is a multidisciplinary journal in marine sciences and geosciences. Therefore, research and review papers and book reviews of general significance to marine sciences and geosciences which are written clearly and well organized will be given preference.
