Extraction and characterisation of gelatin from red stingray fish (Dasyatis akajei) skin / Nurul Fatihah Mohd Fauzi

Gelatin from the skin of red stingray fish (Dasyatis akajei) pretreated witk0.2 M acetic acid and extracted with distilled water at 45 °C for five different extraction times (4, 8, 12, 16 and 20 hrs) were characterized. The yield ranged from 0.081-0.136% (wet weight basis). The protein content range...

The yield ranged from 0.081-0.136% (wet weight basis). The protein content ranged from 10.33-35.33%. The viscosity of the extracted gelatins ranged from 0.277-0.708 Pa.s. The gel strength ranged from 241.07-381.40 g. Yield, protein content and viscosity increased significantly (p<0.05) as the extraction time increased. However, gel strength of gelatin decreased significantly (p<0.05) as the extraction time increased. Those properties were governed by different extraction times. Thus, gelatin can be successfully extracted from the skin of red stingray fish (Dasyatis akajei) using the appropriate extraction time. 2012 Thesis https://ir.uitm.edu.my/id/eprint/53057/ https://ir.uitm.edu.my/id/eprint/53057/1/53057.pdf text en public degree Universiti Teknologi MARA Faculty of Applied Sciences Ismail, Normah (Dr.)
