Supercritical Fluid Extracted Chestnut Tannin as Natural Biocide for Soaking Beamhouse Process of Leather Production

Abstract

Microorganism activity during soaking beamhouse process of leather production is highly dangerous and should be kept under control. Some chemical components are used for this purpose to protect the hides/skins against microbial activities. Because of the banned and restricted substances due to the environmental and health risks in the recent times, natural active ingredients are considered for industrial production as sustainability. Moreover, supercritical fluid extraction as an environmentally friendly technology is applied to isolate biologically active extracts and supercritical extracted natural compounds are reported as potential antioxidant and antibacterial agent for several applications. In this study, supercritical fluid extracted chestnut tannin was used in soaking process of leather production and was determined as potential natural biocide with very good effect against microorganism activity in the process floats.
