    • PROBLEM TO BE SOLVED: To easily convert a feather, that is produced in treatment of waste chicken or broiler and difficult to effectively use as it is, into soluble feather keratin protein.
      SOLUTION: Feather for bedding inner pad is washed with a neutral detergent, washed with water and dried. The feather in an amount of 1 g is fed to a flask of 300 mL, mixed with 50 mL of a thioglycolic acid solution having 0.2 mol/L concentration adjusted to pH 11.0 with sodium hydroxide, stirred and shaken at 30°C for 48 hours, the solution is adjusted to 30°C and adjusted to pH 7 with acetic acid. The solution is mixed with 50 mL of sodium bromate solution having 0.4 mol/L concentration by gradually adding the sodium bromate solution over 4 hours, then the solution is allowed to stand for 20 hours. Then insoluble matter is filtered off from the solution, the solution is adjusted to approximately pH 3.5 with acetic acid, a polymer substance is precipitated and the precipitate is recovered by centrifugal separation. The precipitate is made into a paste state acidic with acetic acid and preserved at a dark cold place. The solubilization does not cause the reduction in molecular weight.

    • 要解决的问题:为了容易地将在废鸡或肉鸡的处理中产生的羽毛轻易地转化为可溶性羽毛角蛋白蛋白。

      解决方案:床垫内垫的羽毛用中性洗涤剂洗涤,用水洗涤并干燥。 将1g的羽毛加入到300mL的烧瓶中,与氢氧化钠调节至pH 11.0的0.2mol / L浓度的0.2mL / L的巯基乙酸溶液50mL混合,在30℃下搅拌并摇动48小时 ,将溶液调节至30℃,用乙酸调节至pH7。 通过在4小时内逐渐加入溴酸钠溶液将溶液与50mL浓度为0.4mol / L的溴酸钠溶液混合,然后静置20小时。 然后从溶液中滤出不溶物质,用乙酸将溶液调节至约pH 3.5,沉淀出聚合物物质并通过离心分离回收沉淀物。 将沉淀物用乙酸酸化成糊状,并在黑暗的寒冷地方保存。 溶解不会导致分子量的降低。 版权所有(C)2010,JPO&INPIT
