中华饮食文化向来善于吸收外来饮食文化并融合为自己的一部分。近代中国人在对待西方饮食文化上抱着一种矛盾心理,一方面既视西餐为"未开化",极尽鄙视与排斥,另一方面又将饮食与西方列强的坚船利炮联系起来,认为其必有先进之处。总体来说,西方饮食文化的传入并没有根本改变中国人的饮食习惯,但却带来了不少"中西合璧"的具体实践,并使一些人士萌生了"吾国人苟能与欧美人同一食品,自不患无强盛之一日"的想法。但在半殖民半封建状态下的近代中国,这种另类的"救亡图存"方案,局限性显而易见。 相似文献

Hydrogen(H2) production from lignocellulosic materials may be enhanced by removing lignin and increasing the porosity of the material prior to enzymatic hydrolysis. Alkaline pretreatment conditions,used to delignify disposable wooden chopsticks(DWC) waste, were investigated. The effects of NaOH concentration, temperature and retention time were examined and it was found that retention time had no effect on lignin removal or carbohydrate released in enzymatic hydrolysate. The highest percentage of lignin removal(41%) was obtained with 2% NaOH at 100℃, correlated with the highest carbohydrate released(67 mg/gpretreated DWC) in the hydrolysate. An enriched culture from a hot spring was used as inoculum for fermentative H2 production, and its optimum initial pH and temperature were determined to be 7.0 and 50℃, respectively. Furthermore, enzymatic hydrolysate from pretreated DWC was successfully demonstrated as a substrate for fermentative H2 production by the enriched culture. The maximum H2 yield and production rate were achieved at 195 mL H2/g total sugarsconsumedand 116 mL H2/(L·day), respectively. 相似文献
