The objective of this study was to amplify vitamin D in white button mushrooms using ultraviolet (UV-B) irradiation and to prepare a vitamin D-fortified superfine mushroom powder through jet milling. Mushrooms irradiated with UV-B for 30 min had a vitamin D concentration of 8.19 μg/g, an amount about 400 times greater than that of the control (0.02 μg/g). The vitamin D-fortified mushrooms were then freeze-dried and conventionally ground or jet-milled to obtain coarse (Dv = 231 μm), fine (Dv = 106.3 μm), and superfine (Dv = 7.1 μm) powders. The vitamin D content was retained during the preparation of the powders. The physical characteristics were evaluated by scanning electron microscopy and hydration properties. The superfine powder of vitamin D-amplified mushrooms was suitable for use as a functional ingredient because its roughness was significantly reduced, and it had a neutral aroma and taste as determined by descriptive analysis.
本研究的目的是利用紫外线(UV-B)照射来提高白平菇中的维生素D含量,并通过气流粉碎制备维生素D强化的超细蘑菇粉。用UV-B照射30分钟的蘑菇维生素D浓度为8.19μg/g,约为对照(0.02μg/g)的400倍。然后将维生素D强化的蘑菇冷冻干燥并进行常规研磨或气流粉碎,以获得粗粉(Dv = 231μm)、细粉(Dv = 106.3μm)和超细粉(Dv = 7.1μm)。在制备粉末的过程中,维生素D含量得以保留。通过扫描电子显微镜和水化特性对物理特性进行了评估。维生素D强化蘑菇的超细粉适合用作功能成分,因为其粗糙度显著降低,并且通过描述性分析确定具有中性的香气和味道。
