Nutrient detection is usually performed by chemical experiment, but this method can easily lead to experimental failure due to difficulty in precise implementation of the experimental protocol. For better results and more efficient use of reagents, it is important to standardize the process. We designed a virtual simulation laboratory system for mushroom nutrient testing, using 3D visualization virtual modeling to construct 3D models of laboratory tools. Using these tools, users can experience realistic simulations of nutrient identification experiments. The system was tested and found to be stable, and trained personnel are well qualified for food nutrient testing.
