A video of a netizen leaving brand Zhong Xue Gao ice cream at room temperature of 31 degrees for an hour without melting has gone viral online, sparking a discussion about food safety among the mesmerized Chinese netizens.

China-based ice cream brand Zhong Xue Gao, known in English as Chicecream, has been popular since its establishment in early 2018, and has been dubbed the "Hermes of ice cream" due to its premium market position.

In the video posted online, Zhong Xue Gao ice cream appears next to a thermometer showing a temperature of 31 degrees. Instead of melting into a liquid, it just transforms into a thick solid.

All ice cream melts, there isn't a completely heat-resistant ice cream, declared the company, adding that the main ingredients used for the ice cream is milk and thin cream, which makes up about 40 percent of the solid content, and that no other water has been included, except a small amount contained in the raw material itself.

"An ice cream made with a high proportion of solids and very little water will naturally thicken when completely melted and will not turn to a puddle of liquid in any case," said the spokesperson of the company. 

The company also added on Monday that in order to maintain the good flavor and shape of the product, it only uses a very small amount of food emulsification thickener, which is added in strict accordance with the relevant national standards and can be safely eaten.
