Giant squid skin gelatin: Chemical composition and biophysical characterization

Properties of film from splendid squid (Loligo formosana) skin gelatin with various extraction temperatures

“…The absorption in the amide-I region is probably the most useful for infrared spectroscopic analysis of the secondary structure of proteins [37,38]. Its exact location depends on the hydrogen bonding and the conformation of protein structure [10]. In the present study, the amide-I peak was observed in the range of 1631 cm −1 , which was in agreement with Hoque et al [4] who stated that the absorption peak at 1631 cm −1 was the characteristic of coiled structure of gelatin for cuttlefish skin gelatin films.…”

Screening and identification of DPP-IV inhibitory peptides from deer skin hydrolysates by an integrated approach of LC–MS/MS and in silico analysis

“…Peptides with various activities have been identified from hydrolysates of fish gelatin Alemán, Giménez, Pérez-Santin, Gómez-Guillen, & Montero, 2011;Byun & Kim, 2001;Li-Chan et al, 2012;Mendis, Rajapakse, & Kim, 2005;Uriarte-Montoya et al, 2011), bovine gelatin (Kim, Kim, & Leem, 2014), porcine gelatin (Hsu, Tung, Huang, & Jao, 2013;Li, Chen, Wang, Ji, & Wu, 2007), and chicken collagen (Saiga et al, 2008). It is well known that the dominant sequence of collagen is a continuous repeating sequence of Gly-X-Y triplets, where X is mostly proline and Y is mostly hydroxyproline (Asghar & Henrickson, 1982).…”

The effect of pretreatment using hydrochloric acid on the characteristics of buffalo hide gelatin

“…These valus met GMIA standard, ranging from 0.3 -2.0% and the maximum value is 2.6% recommended by Muyonga et al (2004) The highest ash content found in the treatment at the HCl concentration of 0.3 M, and then decreasing at the HCl concentration of 0.6M and 0.9M. Low ash content is indicative of good quality gelatin extraction process (Uriarte et al, 2011;Chandra and Shamasundar et al, 2015).…”
