Embodiment Construction

[0028] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0029] In the direction of light propagation, the light whose light vector only vibrates in a fixed direction is called plane polarized light. Since the trajectory of the end point of the light vector is a straight line, it is also called linearly polarized light. When the linearly polarized light passes through the optically active substance, the polarization plane will be rotated (to the right or left) by an angle, and the polarized light cannot pass through the analyzer parallel to the prism axis of the polarizer unimpeded. Only when the analyzer is also rotated (to the right or lef...

Abstract

The invention provides a method for detecting the quality of honey. The method comprises the following steps: step one, preparing to-be-detected honey into at least two honey solutions in different concentrations; step two, respectively detecting polarization directions of emergent light of linear polarization light passing through the at least two honey solution in different concentrations; step three, comparing the difference between the polarization directions of the emergent light passing through the at least two honey solutions in different concentrations, thus determining whether the honey is adulterated or not. The method provided by the invention is simple in operation, high in accuracy and wide in applicability.

Description

technical field [0001] The invention belongs to the field of food testing, in particular to a honey quality testing method and device. Background technique [0002] Honey has always been a kind of natural nourishing food favored by people. However, in recent years, the honey market has been mixed with fish and dragons, and incidents of adulteration and fraud have been continuously exposed. Some manufacturers add fructose and sucrose to natural honey, and the resulting fake honey floods the market, which has a great impact on consumers. Therefore, there is an urgent need for a simple and convenient honey quality detection device to identify the true and false of honey, so as to ensure that pure honey is eaten. [0003] At present, the commonly used methods to detect the quality of honey are C 4 assay, which measures the incorporation of C in honey 4 The amount of vegetable sugar, however, some unscrupulous merchants mix C in honey 3 Vegetables (e.g. rice syrup), at this ...
