Well, in 1908, Kikunae Ikeda identified a fifth 'taste'.

John Prescott, an associate professor at the University of Chicago, suggests that this fifth taste serves a purpose just as the other tastes do.
He suggests that it signals to us the presence of protein in food, in the same way that sweetness indicates that a food contains energy-giveing carbohydrates.
Bitterness, he says, alerts us to toxins in the food, while sourness warns us of spoilage and saltiness signals the presence of minerals.
So, what else do we know about this fifth taste...

味精很自然地加强了一些事物的味道。
因为谷氨酸盐是在自然食物中很常见的氨基酸，所以我们能够发现并尝出它的味道，从进化的角度看，这是说得通的。

In the 1970s, Chinese people were proud of owning an imported shirt and an imported electronic watch. At that time, domestic products were inferior to products of foreign brands both in appearance and function. The idea of worshipping and having blind faith in foreign things has been deeply rooted in the Chinese consumers. With the development of modern science and technology, economy and national strength in China, domestic products at present have made a leap in appearance, quality, elements of science and technology. Many domestic products are even superior to the similar products in foreign brands. Chinese people's attitude toward foreign products has changed from admiration to objectiveness, and finally even to contempt. The psychology of consumers is changing and people are gradually coming back to rational consumption.
