| Abstract: | Peach kernel was used as raw material in this paper.Benzaldehyde was prepared by the acid hydrolysis of amygdalin extracted from peach kernel,and the antimicrobial effects of benzaldehyde were studied by using gaseous antisepsis.The results indicated that amygdalin was hydrolyzed in 0.5mol/L solution of sulfuric acid for 80min at 80℃.In addition,benzaldehyde prepared can effectively inhibit some microorganisms,such as mold and bacteria. |
