摘要: Effects of ultraviolet-C (UV-C) treatment (0.5, 1.0 and 2.0 kJ/m(2)) and cold storage on ergosterol and vitamin D-2 content in different parts of white and brown button mushrooms (Agaricus bisporus) were investigated. UV-C treatment did not significantly affect ergosterol content in the caps and stems of the two mushrooms, but ergosterol content increased significantly during 14 days cold storage. Vitamin D-2 content in the caps and stems of two mushrooms significantly increased as UV-C dose increased, and 2.0 kJ/m(2) UV-C showed the best result. During cold storage, vitamin D-2 content in the caps of the two mushrooms decreased from day 1 to day 7, and then kept stable until day 14, but vitamin D-2 content in the stems of brown mushrooms kept increasing for the whole 14 days period. UV-C could increase vitamin D-2 contents in both caps and stems of white and brown mushrooms without significantly affecting ergosterol content. (C) 2016 Elsevier Ltd. All rights reserved.
