ABSTRACT

Milbond, Trisil, Quibensil, Rekasil, Boldclay and Fusox trademark aluminosilicates were sampled for physical, chemical and in vitro aflatoxin B1 adsorbent efficacy analysis. Each sample was analysed for potassium, sodium, calcium, silicium and aluminum content throughout atomic absorption spectrophotometry. Potassium content varied from zero to 0.89%; calcium from zero to 0.76%; sodium from 0.42% to 1.68%; aluminum from 0.9% to 8.15% and silicium from 13.3% to 62.7%. These findings indicate that some aluminosilicates contain neither potassium nor calcium, but all of them contain sodium, silicium and aluminum. Silicium and aluminum relationship was as follows: Milbond, 0.416; Trisil, 0.356; Quibensil, 0.13; Rekasil, 0.276, Boldclay, 0.337 and Fusox, 0.146. Particle size of Milbond, Trisil, Quibensil and Rekasil corresponded to the zeolite mineral, but Boldclay did not. In vitro adsorbent efficacy of aflatoxin B1 was positive with Milbond and Fusox. These results indicate that there is no control of efficacy in the trademark aluminosilicates used as adsorbent agents of aflatoxin B1 in Mexico.
