“…The mixture was then separated by centrifugation, during which enzyme and unreacted collagen were precipitated, leaving acid‐soluble protein (including peptides and free amino acids) in the supernatant. The acid‐soluble protein content was determined by the Kjeldahl method 11. The peptide content was obtained by subtracting the free amino acid content from the acid‐soluble protein content.…”

The snow crab (Chionoecetes opilio) shells have potential important economical and industrial applications due to their chemical composition. They have a high content of protein (34.2% dw) and essential amino acids; they also have fat (17.1% dw), with a high proportion of o3 polyunsaturated fatty acids. About 28.5% dw corresponds to ash (calcium, phosphorous, and magnesium are the major minerals). The mean concentrations of vitamin E, astaxantin, and b-carotene were 23.3, 9.49, and 0.2 mg/100 g dw, respectively. Results presented in this study indicate that snow crab by-products may serve as excellent nutritional components for future applications in the health and food sectors.Los caparazones del cangrejo de las nieves (Chionoecetes opilio) pueden tener aplicaciones industriales y econo´micas potencialmente importantes debido a su composicio´n quı´mica. En su composicio´n destaca el elevado contenido en proteı´nas (34,2% ms) y aminoa´cidos esenciales, en lı´pidos totales (17,1% ms), con una elevada proporcio´n de a´cidos grasos poliinsaturados o3, en cenizas (28% (ms), principalmente calcio, fosfatos y magnesio. La concentracio´n media de vitamina E es de 23,3 mg /100 g ms, de astaxantina 9,49 mg /100 g ms, de b-caroteno 0,2 mg /100 g ms. El alto contenido en nutrientes, puesto de manifiesto en este estudio, indica que los productos de desecho del cangrejo de las nieves pueden ser utilizados como productos de alto valor an˜adido para su aplicacio´n en suplementacio´n de dietas para alimentacio´n humana y acuicultura.Palabras clave: caparazo´n de Chionoecetes opilio; composicio´n; proteı´nas; lı´pidos; vitamina E; cenizas y minerales; compuestos de alto valor an˜adido.

“…In the last decade, the chemical composition and nutritional value of crustaceans have been investigated worldwide (e.g., Adeyeye, 2002;Çelik et al, 2004;Chen et al, 2007;Gokoolu and Yerlikaya, 2003;Kuçukgulmez et al, 2006;Naczk et al, 2004;Skonberg and Perkins, 2002;Vilasoa-Martínez et al, 2007), and consumption benefits to human health have been much promoted (Bü gel et al, 2001;Oehlenschlä ger, 1997). Yet, only in recent years, attention has been paid to crustaceans' composition of essential elements populations (e.g., bigger animals, more resistant to transport).…”
