1.听写包 答案：

But it wasn't until 1908 that the ingredient in kombu which was responsible for the improvement in flavour wasactually discovered to be glutamate by scientists working there.

From 1908 until 1956,glutamate was produced commercially in Japan by a very slow and expensive means of extraction.
It was in 1956 that the speed of the process was improved, and industrial production increased dramatically and still continues to increase to this day.
In fact,hundreds of thousands of tonnes of MSG are produced all over the world today.
但是直到1908年，科学家才发现海带里面负责提味的成份是谷氨酸盐。
1908年至1956年，日本开始对味精进行商业开发，以一种缓慢又昂贵的提取方式获得味精。
1956年，生产的速度提高了，工业产值大幅度增加，直到今天仍在继续增长。
事实上，如今成千上万吨的味精在全世界生产。
