Abstract

The invention relates to a fast detection method of authenticity of drone pupa powder. The method comprises the following steps: collecting three-dimensional fluorescence spectrum data of drone pupa powder samples; extracting three-dimensional fluorescence spectrum feature peaks of drone pupa powder; and establishing the support-vector-machine algorithm-based fast detection method of authenticitydiscrimination of the drone pupa powder according to the collected three-dimensional fluorescence spectrum data and the feature peaks. According to the method, the characteristic fluorescence spectrumpeaks are screened through parallel factors, the support vector machine-based fast discrimination method of the authenticity of the drone pupa powder is established, and the simple and fast discrimination method of the authenticity of the drone pupa powder is provided for a law enforcement agency.

Description

technical field [0001] The present invention relates to a method for quickly detecting the authenticity of drone pupa powder. The spectral information of the drone pupa powder sample is quickly collected by a three-dimensional fluorescence spectrometer, and the two-dimensional emission spectrum under a representative excitation band is selected as the characteristic detection information of the drone pupa powder. Pattern recognition method to establish a rapid identification method for the authenticity of drone pupae powder. Background technique [0002] Drone chrysalis powder is a functional nutritional food rich in protein, vitamin C and vitamin D. Studies have shown that long-term consumption of drone pupa powder can effectively enhance human immunity, improve memory and prevent tumors. As a functional food, drone pupa powder has important market application potential and broad consumer groups. Although the nutritional value of drone pupae powder is high, the objective ...
