Abstract:

A large amount of inorganic and organic volatile substances produced during aerobic fermentation. Some of these substances, such as NH3, H2S, are the major odors, which pollute the environment and do harm to human health. Combined with the current research at home and abroad, this article summarizes the odor generation mechanism and affecting factors during aerobic fermentation, and mainly analyses odor species produced by different or same raw materials. Combined with VOCs emission standards and some odor thresholds, it proposes that benzene and sulfur compounds should be paid attention. In addition, this research compares the control effect and mechanism of technological parameters optimization and in-situ deodorant additives on odor production and emission, and points out that more attention should be paid to the application of in-situ control technologies and development of effective compound deodorants, so as to provide a reference for aerobic fermentation to control odor emission. This research can also provide a theoretical basis for the further study on control and treatment of odor during aerobic fermentation.
