Application
- Fast detection of sodium dithionite in sugar using a xanthylium-based fluorescent probe.: This study introduces a rapid method for detecting sodium dithionite residues in sugar using a novel xanthylium-based fluorescent probe. The method is highly sensitive and efficient, making it a significant advancement in food safety and quality control (Wang et al., 2024).
- Stabilising mannose using sodium dithionite at alkaline conditions.: Research in the kraft pulping process explores the use of sodium dithionite to stabilize mannose under alkaline conditions. The findings highlight its potential to reduce hemicellulose degradation, providing insights for enhancing the efficiency of chemical pulping processes (Lindén et al., 2020).
