Abstract

The hemicellulosic fraction of brewer’s spent grain (BSG) a waste from the brewing process obtained from National Breweries Harare, Zimbabwe was hydrolysed with dilute hydrochloric acid (HCI) of different concentration range from 1-5% in an auotoclave at 1.5bar for 30mins.The BSG hydrolysate impurities were removed by activated carbon using a platform shaker, filtered through a filter paper using a vacuum filter pump. The BSG hydrolysate was characterised by TLC, refractometer, FTIR and UV-VIS spectrophotometer at 540nm using phenol sulphuric acid method. The results obtained showed positive identification of xylose. Optimum yield of 85% was obtained at 4% dilute HCI. The BSG dilute HCI acid hydrolysate can be an alternative source of xylose.
