Embodiment 1

[0059] The present embodiment provides a kind of classification method of winter honey and black tallow honey, comprising the steps:

[0060] 1) Model construction:

[0061] A. Signal collection: Take 8 real samples of winter honey from Guangdong and 4 real samples of black tallow honey from Guangdong as standard samples, take 2.0±0.1g each, and incubate in advance, incubation time: 20min ;Incubation temperature: 55°C; Then the sample is injected into the gas chromatography-ion mobility spectrometer for detection, and each sample is measured once to obtain the sample spectrum information;

[0062] Among them, the conditions of gas chromatography-ion mobility spectrometry are: chromatographic column: FS-SE-54-CB-0.5 (15m, ID: 0.53mm); column temperature: 60°C; carrier gas flow rate: 0-2min, 2mL / min, 2-20min, 2mL / min-100mL / min; drift gas flow: 150mL / min; carrier gas / drift gas: N 2 ; IMS temperature: 45°C; injection needle temperature: 85°C; injection volume: 500 μL.

Abstract

The invention relates to the field of detection, in particular to a classification method for winter honey and sapium sebiferum honey. The method comprises the following steps: (1) model building: A,signal acquisition; B, database building; C, building of a classification model; and (2) model application. The classification method disclosed by the invention can separately or simultaneously identify the winter honey and the sapium sebiferum honey through a single feature identification region or multiple feature identification regions or stechiometry. No sample pretreatment process is needed in the method, and the method is easy to operate, quick and environmentally friendly; and feature regions are completely visualized. In conclusion, the invention provides a simple and quick gas chromatography-ion migration spectrum analysis method which has important significance for quick identification of the winter honey and the sapium sebiferum honey, promotion of industrial development of beeproducts and facilitation of healthy and sustainable development of the beekeeping industry.

Description

technical field [0001] The invention relates to the detection field, in particular to a method for classifying winter honey and black tallow honey. Background technique [0002] Honey is a natural sweet substance that bees collect from the nectar, secretion or honeydew of plants, combine with their own secretions, and fully brew. Different bee species, nectar source plants, production areas, and even differences in harvesting seasons and processing methods can lead to differences in endogenous active components in honey. [0003] Winter honey usually refers to the honey harvested by Chinese bees in winter. It mainly comes from the nectar of the traditional Chinese medicine tree species Dracula chinensis and wild osmanthus nectar. It is a unique honey species in Lingnan, so it is called winter honey. The air is dry in winter, and the concentration of honey at this time is higher than that of honey harvested in other seasons, and it is amber in color, easy to crystallize, and...
