Embodiment 1

[0036] 1. Sample processing

[0037] (1) All honey samples were stored in a -20°C freezer before analysis.

[0038] (2) Sample preparation: Before the test, all honey samples should be tightly capped and warmed in a water bath at 50°C. After they are completely melted, they should be quickly cooled to room temperature, stirred well, and set aside.

[0039] 2. Detection of physical and chemical indicators

[0040] (1) Determination of moisture content

[0041] Abbe refractometer was used for determination, and the experimental results were expressed in g / 100g.

[0042] Calibration of the refractometer: Before measuring the refractive index of the sample, calibrate the refractive index of the refractometer with fresh distilled water. When the temperature of the water flowing through the refractometer is adjusted to be exactly 40°C, separate the two prisms of the refractometer, wipe them with absorbent cotton dipped in distilled water (if necessary, dip in xylene or ether), an...

Embodiment 2

[0090] 1. Sample processing

[0091] (1) Select 14 kinds of honey samples as shown in Table 1, and store them in -20°C low-temperature refrigerator before analysis.

[0092] (2) Sample preparation: Before the test, all honey samples should be tightly capped and warmed in a water bath at 50°C. After they are completely melted, they should be quickly cooled to room temperature, stirred well, and set aside.

Abstract

The invention provides a method for identifying the honey quality through physical and chemical indexes and an electronic nose technology, and belongs to the technical field of honey identifying methods. The method comprises the following steps that 1, a sample is processed, 2, the physical and chemical indexes are detected; 3, data are collected with an electronic nose; 4, the honey physical and chemical indexes and the data collected by the electronic nose are analyzed by combining a main component analysis method, and a relatively small square law regression model of the electronic nose to the different bee physical and chemical indexes is built; 5, data of honey to be identified are collected through the electronic nose and analyzed through the model obtained in the step 4, the species of the honey is determined, and the physical and chemical indexes of the honey are speculated and roughly calculated. The method for detecting the bee quality is rapid, effective and comprehensive.

Description

technical field [0001] The invention belongs to the technical field of honey identification methods, and in particular relates to a method for identifying honey quality through physical and chemical indicators and electronic nose technology. Background technique [0002] There are many kinds of honey, which are divided into different varieties according to their different nectar source flowers, and are divided into different types according to their different harvesting and processing methods. In the prior art, the identification of honey needs to be measured successively through the determination of physical and chemical indicators such as honey moisture content, soluble solid content, pH value, acidity, and electrical conductivity. The identification method is complicated, time-consuming, and unfavorable for popularization. Contents of the invention [0003] Aiming at the problems existing in the prior art, the object of the present invention is to design and provide a t...
