Abstract Over the past few decades, there has been a significant change in the nutritional intake structure of residents in China, accompanied by a growing concern for the nutritional value of food. This paper introduces a popular science experiment that uses calorimetry to determine the caloric value of food. With simple operations and reliable data from calorimeters, the caloric values of common foods, such as grains and sugars, are measured. The design of the experiment not only helps the public understand the concept of caloric value but also applies it to daily life, addressing popular concerns. The purpose of this experiment is to excite public interest in chemistry, demonstrate its close connection to life, and through experimental education, deepen public understanding of the relationship between food and energy, as well as the importance of chemistry in solving everyday problems.
