While processing includes basic steps like washing, foods cross into ultra-processed territory when they contain preservatives ... avoid sulphites such as sulphur dioxide, sodium bisulfite ...

If such viruses could be recognized as promising sulfur dioxide substitutes in combination with antioxidants, new strategies could be developed to deal with the wine spoilages caused by bacteria.
