英国肯塔基大学一位教授说,从人类的消费上看,由“烟草”叶子当中提取的蛋白质,要比鸡蛋白、干奶酪和牛奶的营养价值都高。这位教授用化学方法从烟草中提取可以溶解的蛋白质。这烟草叶子中所含的蛋白质,跟其它食物相比是一种更加均衡的多种必需的氨基酸的混合物。如果精耕细作,10亩烟草可产生330多公斤无味、无嗅的蛋白质。在处理过程中还产生其它可溶解的蛋白质、纤维和液体残渣。烟草中的尼古丁成分将最终残留在液体中,可以用来做肥料;对昆虫来讲, A professor at the University of Kentucky said that in terms of human consumption, the protein extracted from the leaves of tobacco is higher in nutritional value than egg white, dried cheese and milk. The professor chemically extracted soluble proteins from tobacco. The tobacco leaves contain the protein, a more balanced mixture of many essential amino acids than any other food. If intensive, 10 acres of tobacco can produce more than 330 kilograms of tasteless, odorless protein. Other soluble proteins, fibers and liquid residues are also produced during processing. The nicotine in tobacco will eventually remain in the liquid and can be used as fertilizer; for insects,
