Limiting sucrose loss in Louisiana raw sugar factories: Are biocides necessary?   [Full subscriber]

Abstract Sugarcane sucrose deterioration begins post-harvest causing significant problems for the sugar industry. In Louisiana, the majority of sucrose destruction occurs during storage in mill yards and truck sleeper loads. Raw sugarcane factories in Louisiana apply biocides to reduce sucrose loss caused by bacterial contamination. However, very few factory studies have evaluated biocide usage, and no known studies have included cane grinding rates. During cane juice processing at two Louisiana raw sugar factories this study assessed three biocides, sodium hypochlorite (bleach), carbamate and humulone (hops) using cane grinding or juice flow rates by integrating factory tank and pipe retention times…
