sanitation chemicals is impaired due to lack of proper methodology to evaluate its cost - benefits to the factory. Purity drop method is incorrect, reducing sugar rise from primary juice to mixed juice is time consuming besides being prone to sampling errors. Since there is large variation in cane quality, juice composition; proper composite sampling with juice preservative is crucial. Such analysis, even carried accurately, do not indicate the upstream effect which are likely to be exerted by good biocide. It is known that biocides capable of killing microbes including thermophilic bacteria in cane juice within shortest possible time will control microbial inversion and acid formation in every stage of sugar manufacturing process. The analysis of invert sugars and molasses was carried out and it was found that use of proper biocide for mill sanitation do reflect in the analysis of final molasses. When biocide capable of killing microbes in cane juice is applied for mill sanitation, there is steady but small rise in invert sugar % brix and titrable acidity % brix between every stage of sugar processing. Titrable acidity and invert sugar per 100 brix of final molasses was much lower when Dew mill sanitation chemical is used and the difference is substantial and can be used to evaluate saving of sugar loss from microbial inversion.
