3. Champ d'application et utilisation<\/h4>\n

Sodium Bisulfite is widely used as a food preservative (beverages, dried fruits), water treatment dechlorination agent, and textile bleaching auxiliary. It also serves in chemical synthesis and photography for its strong reducing properties.<\/p>\n

 <\/p>\n

4. l'emballage et le stockage<\/h4>\n

Sodium bisulfite is packaged in 25kg inner PE film-coated kraft paper bags or plastic woven bags. For food-grade use, double-layer moisture-proof packaging is required. Store in a cool and dry place (<25\u2103), strictly sealed to prevent moisture and air (susceptible to oxidation), and keep away from acids and strong oxidants. Pay attention to ventilation during operation (SO\u2082\u00a0may be generated during decomposition). The shelf life is 12 months.<\/p>","protected":false},"excerpt":{"rendered":"
