EDTA-Faafefiloi
O le EDTA ose chelate e puipuia ai mea'ai mai timuga i se va'aiga fa'alelei o le pH (pH 4 - 6.5). E masani ona faʻaaogaina e fafaga ai laʻau i faiga faʻamaʻi ma avea ma mea e faʻaogaina mo elemene. O le EDTA chelate e le afaina ai laula'au, i se isi itu, e lelei mo fuga laulaau e fafaga ai laau. O le EDTA chelate e gaosia e fa'aaoga ai se faiga fa'apitoa pateni micronization. O lenei metotia e faʻamautinoa ai le tafe fua, leai se pefu, microgranule e leai se caking ma faigofie ona faʻaumatia.
