Embodiment
[0035] Embodiment: the present invention is specifically described below in conjunction with accompanying drawing, as Figure 1-5 As shown, a high-precision bulk sugar detection device for food detection and its use method;
[0036] Firstly, 20g of the food sample to be tested is selected, placed on the device, a 200ml beaker is selected, placed on the base 1, and the selected food sample is ground by the grinding wheel 7, after grinding, 25ml of 5mol / L hydrogen chloride solution is added, passed through the equipment After heating the sample for 90 minutes, cool it by water cooling method. After the sample is cooled, add sodium hydroxide to adjust the pH value to 7, then add 15mL of (CH3COO)2Pb with a concentration of 20%, shake well and place 15min to precipitate impurities such as protein and pectin, shake well and transfer to a 200L volumetric flask with distilled water, add water to volume, filter, discard the initial filtrate, collect 5mL filtrate and pass through the pr...

The invention discloses high-precision bulk sugar detection equipment for food detection and a using method of the detection equipment; the equipment comprises the following operating steps of S1, extracting a sample; S2, carrying out pretreating; S3, making a standard solution; S4, carrying out liquid chromatography detection; S5, calculating the total sugar content; and S6, calculating the sugarcontent. The equipment has the beneficial effects that a high-performance liquid chromatography-evaporation light scattering detection analysis method is adopted for detecting the sugar content in the grains, so that the precision is improved; the processing speed is increased by crushing and stirring the food samples, and the reaction time is shortened, the conversion rate of sugar is increased,and the problems that most of existing food sugar content detection methods are relatively low in detection efficiency, relatively low in speed, relatively poor in stability and relatively more in using auxiliary materials are solved.
Description
technical field [0001] The invention relates to the technical field of food detection, in particular to a high-precision bulk sugar detection device for food detection and a use method thereof. Background technique [0002] Food is usually composed of carbohydrates, fat, protein or water, which can provide nutrition or pleasure for human beings or creatures by eating or drinking. With the improvement of people's living standards and health awareness, how to improve food quality, sugar and fat It is an important task in the current food production and processing industry to reduce the residue of harmful substances in food and ensure the quality and safety of food. However, most of the existing food sugar content detection methods have low detection efficiency, slow speed and stability. The accuracy is poor, and more auxiliary materials are used. In view of this, this case came into being after in-depth research on the above-mentioned problems. Contents of the invention [...
