Ajinomoto is the world's first MSG brand, while Bergamot is China's first MSG brand. Bergamot monosodium glutamate is inseparable from a person's name - Wu Yunchu, he is known as the "king of monosodium glutamate", and the origin of the name of monosodium glutamate is also related to him.
 
Wu Yunchu is a chemical engineer based in Shanghai. In 1922, he became interested in Ajinomoto because of its prevalence in China. After research, Wu Yunchu used the hydrolysis method to extract glutamic acid from grains to make monosodium glutamate. He gave the product a new name, "Essence of Taste" – MSG. The following year, Wu Yunchu founded the Tianchu MSG Factory to produce "Buddha's hand" MSG.
 
The packaging design of bergamot MSG was also a must at the time. Because MSG is not meat and can be eaten by vegetarian lovers, Wu Yunchu asked someone to design the packaging bottle into the shape of Guanyin and Luohan. In previous years, China's exhibits were mostly silk and tea, and at the 1926 Philadelphia World Expo, "Bergamot MSG" won the highest award for its first high-profile appearance as a modern industrial product in China. Bergamot MSG has participated in the World Expo three times, and all three times won this award.
 
In just a few years, the sales of bergamot monosodium glutamate have expanded from China to Southeast Asian countries, and the domestic market share has completely exceeded that of Ajinomoto monosodium glutamate. However, the glory of the Buddha's hand brand failed to continue, and in the first industry rectification, Tianchu Company stopped operating due to the problem of monosodium glutamate fermentation pollution, and the "Buddha's hand" trademark was transferred from Tianchu to Guanshengyuan. Although the brand has survived, it has long since lost its former glory.
 
According to the thickness of the crystal, bergamot monosodium glutamate is divided into fine crystals and coarse crystals, both of which are 99% pure monosodium glutamate. The dissolution and absorption of fine crystals in dishes is better than that of coarse crystals, so the sales volume is better than that of coarse crystals, and the number of users who buy is about twice that of coarse crystals, and there is no difference between the two in freshness and taste, and the price is 500g16 yuan, consumers can buy according to their own preferences.
