How to distinguish the quality of glutinous rice balls

"One look". First of all, we need to look at the color of the glutinous rice balls. Normal glutinous rice balls are glutinous rice white, and slightly green is normal. If the color is too white, it may contain whitening agents that are harmful to the human body. If the color is red, it means that the glutinous rice balls have gone bad and cannot be eaten.

"Two smells". When buying glutinous rice balls in bulk or in open packages, smell them first. Normal glutinous rice balls smell like raw rice. Smells of sour, fishy, ​​motor oil, diesel, etc. are abnormal. When buying packaged glutinous rice balls, check whether the packaging material is the material specified by the state, smell the packaging for any peculiar smell, and whether the glutinous rice balls are stained with the packaging color.

"Three observations". Observe the manufacturer, production date, and shelf life on the glutinous rice dumpling packaging; observe whether the net content of the quantitatively packaged glutinous rice dumplings meets the national regulations and requirements, and re-weigh them on a "fair scale" to avoid shortfalls; when buying glutinous rice dumplings made on site, observe the hygiene conditions of the processing site and employees.

Why do glutinous rice balls float?

Raw glutinous rice balls are denser and have a higher density than water. When they are put into water, their gravity is greater than their buoyancy, so they sink to the bottom of the pot. After the glutinous rice balls are put into the pot, as the water temperature rises, the filling and skin of the glutinous rice balls absorb the hot water and gradually expand, increasing their volume. The volume of water displaced increases, and the buoyancy they experience increases. When the glutinous rice balls are fully expanded, their buoyancy is greater than their gravity, so they float.
