Extraction Process Modification to Enhance Properties of Skin Gelatin of Pangas Catfish (Pangasius pangasius)
This study was aimed at studying the effect of preliminary treatment variations on the pangas catfish (Pangasius pangasius) skin gelatin, particularly the gel strength. The preliminary treatment using the whiting solution gave higher gelatin property (P<0.05) than that using alum (Al3(SO4)2) and Calcium Hydroxide (Ca(OH)2). High gelatin (dry basis) was 23.37% and gel strength was 360.18 g. The ...
متن کاملResponses of growth rates and growth hormone levels of African catfish (Clarias gariepinus) to stocking density
In order to estimate responses of growth rate and growth hormone of Clarias gariepinus to stocking density, fish (initial weight 30.71 ± 0.89 g) were stocked in 120-L tanks at densities of 35, 65, 95, and 125 kg/m3 for 60 days. On day 30 and 60, the fish growth rates were measured, pituitary growth hormone (GH) mRNA levels and serum GH concentrations were examined by real-time qPCR and ELISA te...

متن کاملPurification and characterization of a cathepsin inhibitor from catfish (Pangasius sp.) of Indonesian water
Cathepsin inhibitor has been purified to homogeneity from catfish muscle (Pangasius sp.). The purification was carried out through ammonium sulphate precipitation, followed by ion exchange chromatography using DEAE-Sephadex A-75, followed by gel filtration on Sephadex G-100. Throughout the purification procedure, cathepsin inhibitory activity was determined against hemoglobin. A single band of ...
