The sodium metabisulfite (Sodium metabisulfite description) treatment was highly effective in maintaining the integrity and freshness of fruit and vegetable discards, suppressing microbial proliferation, and preserving the nutrient constituents. Under the conditions of this study, sodium metabisulfite effectively preserved fruit and vegetable discards in an aerobic environment, enabling their more efficient long-term recycling through livestock feed or development of value-added products (1).

This study aimed to evaluate the effect of the application of sodium metabisulfite (SMB) on the bond strength of bleached teeth. The use of 25% SMB gel immediately after bleaching was able to reverse the deleterious effect of bleaching on the bond strength of dental composites to dentin (2).

Calcinosis cutis is a chronic calcium-mediated disease that causes significant morbidity. Multiple treatments have been tried, with varying results; indeed, to date, no standard treatment has been generally accepted. Sodium metabisulfite is an inorganic compound that, when it reacts with oxygen, becomes sodium sulfate, a metabolite of sodium thiosulfate that has a similar ability to inhibit calcium oxalate agglomeration. Four women diagnosed with calcinosis cutis, secondary to dermatomyositis, systemic sclerosis and radiodermatitis after breast cancer, were evaluated for their response to topical 25% sodium metabisulfite. In all patients a decrease in lesion size, erythema and pain from injuries was shown, with complete resolution of the associated ulcers. One patient had a complete response. None experienced adverse effects. Topical sodium metabisulfite is a promising emerging therapy that should be considered as a valid alternative treatment in calcinosis cutis. Randomized prospective studies are required to evaluate its true efficacy (3).
