Abstract

[Utilization of cassava fibrous waste (tippi) in production of confectioner's syrup was investigated.] Acid hydrolysis of starch present in cassava fibrous waste results in formation of a brownish-yellow hydrolysate due to the requirement for a higher acid concn. than that needed in the case of pure starch. Thus application of stronger downstream processing operations, such as deproteinization, clarification and decoloration, are needed to obtain a confectioner's syrup conforming to standards. Among the various deproteinizing agents evaluated, bentonite and kaolin were the best, their use resulting in removal of 20% protein and 60-70% red as well as yellow colours. Kaolin was selected based on economic considerations. Data indicated that 5% (w/v) kaolin, 10 min contact time at 25
