Popis

Application

• Development of Low Sodium Table Butter via Partial Replacement of Sodium Chloride with Potassium Chloride.: This study explores reducing sodium content in table butter by substituting sodium chloride with potassium chloride. The findings are significant for chemists focused on food chemistry and the development of healthier food products with acceptable sensory characteristics (Biointerface Research in Applied Chemistry, 2020).
