영문 초록

To examine of possibility protein recycling of shaving scraps contained chrome generated from manufacturing process of leather, the characteristics of hydrolyzed protein that differently treated with MgO as alkaline agent were investigated. 1n alkaline hydrolysis of saving scraps treated with MgO, MgO had to be treated over 5.0% to maintain over pH 8.0 that is insoluble of chrome. Under the condition of alkaline treated with MgO, the solubility of chrome is low with about 60%. The average molecular weight of hydrolyzed proteins from shaving scraps treated with MgO was about 80 ~ 100 KD. The amino acid contents of that were largely collagen proteins such as glycine , alanine and proline, and acidic amino acids such as aspartic acid and glutatamic acid. The contents of Mg, Ca and Na in hydrolyzed protein were too much as liquid fertilizer , and chrome contents was 30 ~ 40 ppm that largely decreased in comparing with raw materials (40, 000 - 42, 000 ppm).
