    • An efficient low-cost method of proteoglycan recovery from natural resources. There is provided a process for producing proteoglycan, comprising the steps of immersing a biological sample containing proteoglycan in an alkali solution of 0.0025 to 0.1 N and recovering the solution after the immersion. As compared with the conventional extraction method, proteoglycan can be recovered in unaltered undecomposed form easily within a short period of time, thereby attaining substantial reduction of proteoglycan production cost. Further, proteoglycan highly useful in industry can be recovered from wasted portions of fin, feather, mammal, etc. having mainly been discarded, thereby contributing toward effective utilization of industrial waste and reduction of the volume of industrial waste per se.
    • 一种从自然资源中回收蛋白多糖的有效低成本方法。 提供了一种生产蛋白聚糖的方法,包括将含有蛋白多糖的生物样品浸入0.0025至0.1N的碱性溶液中并在浸渍后回收该溶液的步骤。 与常规提取方法相比,蛋白多糖可以在短时间内容易地以未改变的未分解形式回收,从而大大降低了蛋白多糖的生产成本。 此外,在工业中非常有用的蛋白多糖可以从主要被丢弃的鳍,羽毛,哺乳动物等的浪费部分中回收,从而有助于有效利用工业废物和减少工业废物本身的体积。
