Patulin contamination within apple products poses a serious health risk to consumers. Studies done on laboratory animals have demonstrated that patulin has a broad spectrum of toxicity, including mutagen city and carcinogenicity. The aim of the experiment was studying influence of selectively acting activated carbon powder--Ercarbon SH （Erbsloh, Germany） which is special produced for lowering HMF （hydroxy methyl furfural）, on reduction of patulin content in clear apple juice. Industrial apple row material with some damaged parts was pressed, juice was pasteurized at 95 ℃ during 2 min. After cooling on 55 ℃, enzymatic treated and clarified juice were filtered by 0.45 [am pore sizes membrane filter, Apple clear juice sample was divided for five parts. The samples of apple juice were diluted to 11.5° Brix and contacted with concentrations of 2, 2.5, 3 and 3.5 g/L activated carbon powder for 30 min. After filtration in the experimental samples, putulin was quantitatively determined by HPLC （high performance liquid chromatography with UV） detector at 276 nm. The research revealed that the best results were achieved by treatment with activated carbon in its powder form at concentration of 2.5 g/L with 30 min contact time.展开更多
