Popis: | Three different magnetizations of magnetic chitosan were prepared by combining different ratios of Fe3O4 particles and chitosan using Triton X-100 as the emulsifier. The superior magnetic chitosan was selected to conduct the patulin adsorption behavior assay based on the adsorbents granular morphologies, adsorbents recoverability and patulin adsorption efficiency. The results revealed that magnetic chitosan which the ratio of Fe3O4 particles to chitosan is 1:1 was the superior patulin adsorbent with patulin adsorption of 89% and adsorbent recovery of 99.5%. Patulin adsorption study showed that with adding 100 mg magnetic chitosan into 10 mL 200 μg/L patulin contaminated kiwi fruit juice for 9 h at 35 °C, patulin adsorption capability reached the maximum of 19.4 μg/g. Also, its paulin adsorption behavior followed pseudo-second-order process and was fitted well with Langmuir isotherm model. Furthermore, magnetic chitosan application research indicated that the quality and flavor of kiwi fruit juice was without any change except color and luster better than before. This study furnished an excellent paulin adsorbent for its great potential application in juice processing industry. |
