bisulfite
Wine additive chemical
Bisulfite is a chemical compound containing the HSO₃⁻ ion, used industrially in food preservation, water treatment, and paper manufacturing.
Sodium bisulfite prevents browning in dried fruits and wines.
In molecular biology, bisulfite treatment converts unmethylated cytosine to uracil, enabling researchers to map DNA methylation patterns: bisulfite sequencing.
