纳米-氧化镁荷正电无机陶瓷膜的制备及对葡萄汁中赭曲霉毒素A的静电吸附
Synthesis of nano-MgO positively charged inorganic ceramic membrane and electrostatic adsorption for ochratoxin A in grape juice
摘要
Abstract
Ochratoxin A(OTA)is an important mycotoxin that widely exists in grape products,especially in wine and grape juice.The traditional physical removal methods for OTA are limited by single material,difficult removal of adsorbents,and affecting the nutri-tional quality.Nano-MgO positively charged inorganic ceramic membrane was prepared by impregnation-thermal decomposition with urea,MgCl2·6H2O and dispersant,and the optimal conditions for OTA adsorption were tested.Nano-MgO positively charged inorganic ceramic membrane was applied to remove OTA in grape juice,and the quality and flavor changes of grape juice were also analyzed.The results showed that nano-MgO cubes increased specific surface area and changed the electric properties of the ceramic membrane.The removal rate of OTA in grape juice was over 91%,and the overall nutritional quality and aroma substances of grape juice was preserved.关键词
