Bone Deproteinization Skipjack (Katsuwonus Pelamis L) With NaOH In Concentration And Time Difference Hydrolisis

In tuna fish processing business is handled in large and small scale industrial waste generated both solid waste and liquid waste that has not been fully utilized, and the wastes can cause environmental pollution. Tuna has around 61.79% as edible portion, the part that can be eaten, while the remaining 38.21% are waste including bone parts (Prih et al. 1982). According to Lengkey, et al (2011), even there are indicated that skipjack tuna gill meal in ration has no significantly effect on broiler carcass, but it can replace the function of fish meal in the ration. Tuna fish bone (Katsuwonus pelamis L) as well as animal bones in general, containing intercellular substance (about 70%) and the 30% remains, as inorganic salts of organic matrix. 95% of the organic component is formed from collagen, the basic substance of the remainder consists of proteoglycan and non-collagen molecules that appear to be involved in the regulation of bone mineralization. Collagen in the bone is approximately half of the total body collagen, and its structure is similar to the collagen in other tissues binder. Almost all of it, is type I fiber. Three-dimensional space on the structure called hole zones, are home to deposits of minerals.
