Beginning in 1997, Leung wrote about food, making significant contributions to poetry in Chinese. Drawing literary texts from Leung＇s collections of poetry, this paper aims to cast light on the role that Leung has played in the shaping of foodscape poetics and how he elaborates and addresses historical memory and cultural politics. In addition, this paper contends that his deconstruction of nationalism and an emphasis on ＂wisdom of peoples＇ livlihood＂ lies at the core of Leung＇s foodscape poetics, and they constitute a ＂positionality＂ rooted in his experience in Hong Kong.展开更多

文摘采用纤维素酶水解方法提取铁观音茶多糖,并对其脱蛋白工艺进行了研究.酶法提取的正交实验结果表明,铁观音茶多糖的得率随酶用量和水解时间的增加而增大,随pH值和温度的升高先增后降,最佳的酶处理条件为:加酶量15 mg/g,pH=4.0,水解温度45℃以及水解时间90 m in.比较了Sevag法、三氯醋酸法以及酶与三氯醋酸结合法对铁观音茶多糖的脱蛋白效果,结果表明,三氯醋酸法可以简单高效地去除蛋白质,而又不会造成多糖过多损失,4 mol/L三氯醋酸溶液的最佳使用量为2%(v/v).
