EENHANCING ANTIOXIDANT CAPACITY BY NANO TREATMENTS FOR MUCROTT PEEL UNDER DIFFERENT DRYING CONDITIONS
Mucrott belongs to the Rutaceae family, which is one of the major Taiwanese winter citrus fruit products.The peels of Mucrott contain many active phytochemicals which can be dried to make chenpi, a popular traditional Chinese medicine.In this study, Mucrott peels and a whole Mucrott were dried at different hot-air drying temperatures (50℃, 60℃, 70℃) and then were examined by a nano wet-grinding machine in a nano process.The results showed that higher drying temperatures caused the color of Mucrott to deepen and also did more damage to their microstructure.For antioxidant capacity, the nano wet-grinding brought about higher total polyphenolic and flavonoid contents.Among these, the highest content for nobiletin and tangeretin were 4.725 mg/g and 1.881 mg/g, respectively, as measured by HPLC analysis.Hot-air drying at 70℃ was most suitable for the chenpi process, and dried Mucrott peels in all respects were better than when the Mucrott was dried whole.
