参考译文:
新型的健康肉制品将不再是诸如猪肉或是自然饲养的牛肉了。如果那些有远见的科学家成功了的话.将来的肉制品无论从口感还是外观上看都与以前的没有什么,区别,唯一不同的只是它们是在实验室里制成的。
一些专家正在从事这样一项工作:他们把含有动物肌肉细胞的肉养在盘子里。而现在的技术离这些肉上市还有很长一段路要走。但是专家坚信这将是产生一种新型美国饮食的有效方法,这样的肉对人体也会更健康。此外,这种在实验室里研制出来的肉制品意味着专家们可以对肉的脂肪、蛋白质和其他一些指标进行控制,从而生产出污染少的肉制品。那么或许到那时麦当劳的早餐肉就能使人们远离而不是让人患上心脏疾病。
然而,仍有一些科学家对此产生了质疑。他们说:“无论从技术还是经济上来说,这都不实际。”毕竟,肉制品不是简单的肌肉细胞组合,而是一种由脂肪、神经、血管和相关组织结合在一起的复杂结合体。每种细胞在其成品的口感上都起着一定的作用。这种结构的模仿对产品具有良好的口感是必需的。事实上,在实验室里研制肉制品并不是一种新的观点。早在1912年,一位法国科学家就做过这样一个试验:他将鸡心上的组织养在有营养旁的玻璃瓶里。这些肌肉组织存活了30多年——竟然比这位科学家活的时间还长!至于成本,专家们正试图将其降低。因为现在这种实验室肉制品一磅大约要花费1000至5000美元。就目前的消费水平来说,人们根本无法接受。
在这个禽流感、疯牛病不断出现,人口密度不断加大,探测火星的壮志不断升华的时代,实验室肉制品必将会走向市场。但是食品消费一直以来都是一种保守的文化现象,对这一趋势的适应还需要很长的时间。
