摘要: The drying process used for persimmon fruit (Diospyros kaki) can alter the composition of nutrients, and especially vitamins. We visually determined whether amounts vitamin A1, B6 C vary after fruit, using matrix-assisted laser desorption/ionization (MALDI) mass spectrometry (MS) imaging. Drying altered amount moisture between interior surface. Vitamin A1 is lipophilic localized at desiccated outer regions (pericarp) not in inner region (mesocarp endocarp), its concentration was increased 3.4 times dried compared with raw persimmon. B1 are water-soluble concentrated moist mesocarp. content decreased by sun. affected localizations all observed opposite localization to due being water soluble. Multiplevitamin imaging MALDI-MSI has great potential enhancing commodity value investigating effects manufacturing processes.
