Sour is the new sweet in China – young Chinese food scientists play with vinegar

Vinegar, i.e. the Chinese cereals-based vinegar, has been an important ingredient in Chinese cuisine for ages. A famous application is vinegar-based dipping for dumplings.

Vinegar is a growth product in China, although only 30% of the output is branded vinegar with the remaining 70% workshop-style factories. China has produced 4.61 mln mt of vinegar in 2022; up 3.83%.

A traditionally important vinegar region is Shanxi province. Qingxu county in Shanxi is often referred to as the ‘vinegar capital‘ of China.

However, it was not regarded as something for direct consumption by most Chinese, who preferred their snacks and soft drinks sweet, sweeter, sweetest. Until recently, that is. The past 2 – 3 years have seen a surge in so called ‘vinegar beverages’ (cuyinliao). These are mildly acid drinks made of naturally acidified fruit juice (apple vinegar is the top product in this category) or drinks produced by mixing vinegar with other ingredients. These products are advertised as healthier choices than the traditional sugary drinks.

This product group has grown so rapidly, that China’s top vinegar producer, Hengshun, with 83.8% market share in 2018, has organised a competition for students of food science in various Chinese universities to design new types of drinks, but also foods, based on vinegar. The various products the next generation of Chinese food scientists came up with is so interesting, that I will list the top products in this post.

First prize

Apple Vinegar drink

Apart from this contest, vinegar-flavoured icecream has appeared in China as well in the course of 2018. This photo has been taken in Taiyuan (Shanxi).
