Sugar Technology Laboratory

VSI Sugar Technology Department has a state-of-the-art equipped Sugar Laboratory for analysis of sugar, molasses and other intermediate products from sugar manufacturing process and boiler water.

While exporting refined/raw sugar, quality control is one of the important areas. VSI sugar laboratory helps in assessing refined/raw sugar quality.
This laboratory provides analytical services to all the concerned dealing with sugar and other byproducts as per demand. Around 650 sugar and molasses samples are analysed per year for the parameters requested by the clients.
The Manager of the laboratory is working as Associate referee for the ICUMSA. The laboratory has participated three times in collaborative testing organized by the ICUMSA. The results obtained were to the level of expectations of the ICUMSA.
