Through improving preparation process, the optimal purify processes could hence the yield, decrease the chemical supplementation in the production process. The prepared keratin product is 10 times more valuable than the feather meal product. Through analysis the production of keratin characteristics, it will provide the basal data for future use of keratin in biomedical materials utilization. Spent hen breast meat has been successfully developed as an omega-3 fatty acid fortified surimi-like products.However, the easy peroxidation is a big problem on food fortified omega-3 fatty acids.The antioxidant addition can retard lipid peroxidation.However, α-tocopherol addition can not beobserved to retard lipid rancidity of this product while a healthy worry is concerned in artificial antioxidant, i.e. BHA and BHT.The antioxidant effect of rosemary on pork patties was reported, and meanwhile, this ability is contributed to it s phytochemical contents.Besides, the air induction and temperature increase during the period of blending of lipids and chicken surimi are also reasons for lipid peroxidation.Hence, via antioxidant rosemary extract and improvement of processing step, it is possible to prolong the shelf life of omega-3 fatty acid fortified chicken surimi. Hence, the results of this proposal will not only benefit poultry industry, thus bring the income but also increase the functionalities of meat products, thus offering other choices of health meat products羽毛角蛋白純化生物基材Omega-3脂肪酸雞肉筋蛋白介護食品feather keratinpurificationbiomaterialOmega-3 fatty acidchicken surimiuniversal design foods for the aged person開發家禽生產系統及提升產品附加價值計畫-提高家禽產品附加價值
