Abstract: The calorific value is an important physical data to measure the quality of materials. It can provide a new idea and method for evaluating the quality of similar foods from the energy point of view. The calorific values of 12 kinds of tea samples were determined by bomb calorimeter in this study. The results showed that the calorific values of these tea foods ranged from 14.96βkJ·g-1 to 16.16βkJ·g-1. The determining method was simple, easy to operate. Understanding the calorific value of tea had a certain guiding and referencing significance for the development, utilization, storage and consumption of tea foods.

Key words: bomb calorimeter, tea, calorific value
