PROBLEM TO BE SOLVED: To provide a method of manufacturing the food taking an unused part of a beef cattle as a raw material and containing chondroitin sulfate and collagen that are a function nutrient composition serving to prevent the senility accompanying with aging.SOLUTION: The method includes the first step (1) for acquiring solution by crushing an unused part of a beef cattle, hydrolyzing and heating the crushed product, and supplying a dialytic ferment, the second step (2) for separating the solution into water-soluble component and fat content through a separator and acquiring a filtered extract, the third step (3) for acquiring a decolorized purified extract liquid containing chondroitin sulfate, collagen peptide and amino acid by passing through a filtration filter, the fourth step (4) for acquiring a concentrated liquid by electrically dialyzing with an electrodialysis machine and concentrating the purified extract liquid until a solid concentration in a solution becomes Brix 45 degree through heat concentration under depressurization for sterilization and concentration, and the fifth step (5) for acquiring a white powder function nutritious food in which chondroitin sulfate and collagen are carried by being adsorbed in the sugar of the dextrin through addition and drying of dextrin powders/lactose powders.COPYRIGHT: (C)2013,JPO&INPIT【課題】肉牛の未利用部位を原料として、加齢に伴う老化防止の働きを担う機能栄養成分であるコンドロイチン硫酸、コラーゲンを含む食品の製造方法を提供する。【解決手段】(1)肉牛の未利用部位を粉砕し、粉砕物を加水加熱、分解酵素を投入し酵素分解し溶解物を得る第1の工程。(2)分離機にかけて水溶性成分と脂肪分とに分離しろ過された抽出液を得る第2の工程。(3)ろ過フィルタを通過させてコンドロイチン硫酸、コラーゲンペプチド、アミノ酸を含み、脱色された精製抽出液を得る第3の工程。(4)電気透析機にかけて電気透析し、さらに減圧下で加熱濃縮して殺菌・濃縮し溶液中の固形分濃度がBrix45度となるまで濃縮し濃縮液を得る第4の工程。(5)デキストリン粉末/ラクトース粉末を添加し乾燥させることにより、コンドロイチン硫酸、コラーゲンをデキストリンの糖に吸着させ担持させた白色粉末状の機能栄養食品を得る第5の工程からなる。【選択図】図1
