Authors have shared their experiences about syrup diversion from sulphitation plant to distillery at DCM Shriram Ltd, Sugar Unit Ajbapur during crushing season 2021-22. In this study effort has been made to address key issues of how syrup quality and composition are key components for higher yield during ethanol production. Sugar cane from the field gets infected with number of microorganisms. As the bacterial contamination during sugar processing increases, not only unknown losses increases but also there is increase in volatile acidity of the intermediate products. The major volatile fatty acids present are acetic acid, butyric acid, propionic acid and valeric acid. In contamination to Contamination increases rapidly in Sulphitation process in comparison to defecation process due to presence of SO2 gas. To keep the level of organic volatile acids at a minimum, the microbial contamination at every point in sugar processing, should be minimized or controlled. The present case study has undertaken to elaborate some of the possible challenges of syrup diversion in Sulphitation sugar plant and further addresses the steps to be followed for controlling the quality and contamination level of syrup.
