Nutrient composition of raw and cooked meat of male southern king crab (Lithodes santolla Molina, 1782)

This study provides information about nutrient composition of adult males of southern king crab (Lithodes santolla). Proximate composition of raw and cooked meat (g/100 g meat) averaged: moisture=80.9 and 78.6, protein=14.6 and 16.3, fat=0.70 and 0.76, and ash=2.03 and 2.10, respectively. Arginine, glutamic acid, leucine, and aspartic acid (20.4, 9.4, 8.0, and 7.9 g aa/100 g protein, respectively) were the major amino acids. The predominant fatty acid was 18:1n-9c (21.8 and 22.1%), followed by 20:5n-3 (17.1 and 21.8%), 16:0 (15.8 and 15.3%), and 22:6n-3 (11.0 and 13.5%). Cooked meat contained more cholesterol (51.0 mg/100 g meat) and phospholipids (60.1 mg/100 g meat) than raw meat (37.3 and 13.9 mg/100 g meat, respectively), with phosphatidylcholine representing over 80% of the total phospholipid content. The main tocopherol was -tocopherol (raw meat=1.30 mg/100 g meat, cooked meat=1.14 mg/100 g meat). Major mineral contents of raw and cooked meat (mg/100 g meat) were: Na=509 and 594, K=179 and 203, Ca=114 and 197, P=126 and 143, Mg=34 and 41, Fe=1.26 and 1.86, and Zn=1.88 and 2.64, respectively. Thus, the nutritional quality of the cooked meat of the southern king crab makes it especially adequate for cholesterol-restricted, balanced low-fat meat diets. Fil: Risso, Susana Josefina.
