The results showed that, with respective addition of 6% modified starch, O. 1% compound phosphate, 10% maltodextrin, 0.4% guar gum, 0.4% distilled monoglyceride and 0.3% transglutaminase, the drying rate, rehydration ratio and sense value of the frozen dumpling wrappers were the highest.展开更多

The female of Libnotes（Libnotes） pseudonohirai Men, 2015 is described and illustrated for the first time. The males of Holorusia henana Yang, 1999 and Tipula（Vestiplex） jiangi Yang ＆ Yang, 1991 are redescribed and illustrated with new morphological characters. A key to all species is provided.展开更多
