Characterization of Acid‐soluble Collagen from Pacific Whiting Surimi Processing Byproducts

Abstract

Three different solid byproducts (skin, frame, and refiner discharge) from Pacific whiting surimi manufacturing are a good resource for collagen extraction according to their total protein concentrations and other biochemical properties. Denaturation temperature of acid-soluble collagens was 23.3°C for refiner discharge, 21.7°C for skin, and 20.6°C for frame. Based on the functional properties, acid-soluble collagen from refiner discharge was the best and showed potential as an ingredient in processed food manufacturing.

The extraction of gelatine from mackerel (Scomber scombrus) heads with the use of different organic acids

“…All gelatines were very low in tyrosine and histidine. These results were in agreement with those found by Kim and Park (2004) for acid-soluble collagen from Pacific whiting. However, relatively high contents in cysteine were observed giving an indication of possible contamination by non-collagenous proteins in the extraction process (Morimura et al, 2002).…”

Seafood Processing By-products: Collagen and Gelatin

“…Acid-soluble collagen is the best in terms of the immediate emulsifying activity, while pepsin-soluble collagen is the best regarding emulsion stability. The acid-soluble collagen from Pacifi c whiting surimi refi ner discharge was found to be higher compared with both acid-soluble collagen from skin and the commercial emulsifi er Tween-80 (Kim and Park 2004 ).…”

“…The extraction and functional characterization of acid-and/or pepsin-soluble collagen has been reported for different fi sh species, such as Pacifi c whiting (Kim and Park 2004 ), plaice ( Pleuronectes platessa ) (Montero et al 1995 ), squid ( Illex coindetii ) (Ruiz-Capillas et al 2002 ), Alaska pollock (Park et al 2007 ), deep-sea redfi sh (Lin et al 2008 ), threadfi n bream (Nalinanon et al 2008 ), walleye pollock (Yan et al 2008 ), brownstripe red snapper (Jongjareonrak et al 2005 ), or unicorn leatherjacket ( Aluterus monoceros ) (Ahmad et al 2010 ).…”

“…The denaturation temperature of acid-soluble collagen was 23.3 °C, 21.7 °C, and 20.6 °C for refi ner discharge, skin, and frame, respectively. Acid-soluble collagen was considered as the best on the basis of functional properties and showed potential to be an ingredient in food processed manufacturing (Kim and Park 2004 ).…”
