Scattering spectrum detection method of true and false honey

Abstract

The invention discloses a scattering spectrum detection method of true and false honey. After sequentially passing through a half-wave plate, a polarizing film, a quarter-wave plate and a first convex lens, laser of a first laser is incident in true honey in a glass tank, and a backward stimulated Brillouin scattering signal is generated; after being reflected through the polarizing film, the backward stimulated Brillouin scattering signal is reflected to a second convex lens through a reflector, and is collimated through a first slit after being converged through the second convex lens; the collimated signal passes through a non-spherical head mirror and a narrow second slit; spectral processing is carried out through a F-P etalon; the true honey in the glass tank is changed into false honey; the true honey and the false honey are analyzed, processed and compared through a first computer; respective backward stimulated Brillouin scattering spectrograms of the true and false honey are obtained, and the true and false honey can be identified. The scattering spectrum detection method disclosed by the invention has the advantages of being simple to operate, free of pollution, low in cost, high in speed, high in efficiency and the like in the event of detecting the true and false honey.

Description

technical field [0001] The invention relates to the technical field of photon detection in food detection, in particular to a scattering spectrum detection method for true and false honey. Background technique [0002] Natural honey is not allowed to add foreign substances or remove certain ingredients from honey. Natural honey is a sweet substance brewed by bees after collecting the nectary of the flower of the nectar source plant and adding their own special substances, which are stored in the gland. However, driven by economic interests, many unscrupulous traders mix cheap high-fructose syrup into honey, and what's more, they directly use syrup instead of natural honey. Since syrup is similar to fructose and glucose in honey, it is difficult to detect it by sensory detection and conventional chemical analysis. The commonly used stable carbon isotope method to determine the adulteration in honey However, the isotope mass spectrometer used in this method is expensive and...

Problems solved by technology

The commonly used stable carbon isotope method to determine the adulteration in honey However, the isotope mass spectrometer used in this method is expensive and takes a long time to measure. More importantly, both rice and nectar plants are Plants, and the isotopic composition of rice high fructose syrup derived from rice is very similar to natural honey, so it is difficult to detect whether natural honey is adulterated by this method
