Shamshiri and Rahemi determined the effect of post harvest treatment on the ripening and quality of Mazafati date fruits using acetic acid (2%), sodium chloride (2%), or a combination of 2% acetic acid with sodium chloride. Either separately or combined sodium chloride and acetic acid significantly increased total soluble solids (TSS), but reduced fruit firmness and moisture content. Acetic acid at 2% had a greater effect on fruit ripening than sodium chloride, but fruits that were treated with sodium chloride were better in appearanceShamshiri and Rahemi, 1999).
