Embodiment 1

[0032] This embodiment introduces the device and its functions of the present invention.

[0033] A food quality analysis and detection device, comprising a general control module 11, an image analysis module, a hardness analysis module, a water content analysis module, an infrared spectrum analysis module and a mobile terminal 10;

[0034] The total control module 11 is electrically connected to the image analysis module, the hardness analysis module, the water content analysis module, and the infrared spectrum analysis module, and the total control module 11 is wirelessly connected to the mobile terminal 10; the mobile terminal 10 is used to take overall image shots of the food to be analyzed, and Send the captured image to the general control module 11 to identify the type of food to be analyzed;

[0035] The image analysis module is used to collect images of the food samples to be analyzed, and analyze the collected images to obtain the first freshness of the food to be an...

Embodiment 2

[0048] This embodiment introduces the analysis method of the present invention. The method of use is as follows:

[0049] First, use the mobile terminal to take the overall image of the food to be analyzed, and then upload it to the cloud server. The cloud server analyzes the image to obtain the type of food to be analyzed, such as cake, cucumber, tomato, apple, etc.; Species, such as Red Fuji apple, Marshal Huang apple, Aksu pear, etc.;

[0050] Then cut the food to be analyzed and put it into the detection station of the sample tray for image detection to obtain the first freshness; then conduct infrared spectrum detection to obtain the second freshness, the second hardness coefficient, and the second water content. Then perform a hardness test to obtain a first hardness coefficient; perform a water content test after the hardness test to obtain a first water content;

[0051] After the total control module 11 obtains the first freshness, the first hardness coefficient, th...

Embodiment 3

[0055] The device of the present invention can also comprehensively test the hardness coefficient and water content to obtain the water loss-hardness coefficient curve;

[0056] When judging the grade of the hardness coefficient, the hardness coefficient under a fixed water content is first selected for judgment, so as to ensure that the hardness is carried out under the same water content, thereby improving the detection accuracy of the hardness grade.

Abstract

The invention relates to a food quality analysis and detection device. Physical detection and intelligent identification are combined, firstly, food can be photographed and identified on a mobile terminal to obtain the type of the food, then the detection function of the device is used for detecting images, water content and hardness in a targeted mode, and the quality grade of the food can be obtained more directly; secondly, the device is portable, the food quality can be comprehensively judged only according to the appearance, the water content and the hardness of a collected sample, complex chemical analysis and detection are not needed, and the device is suitable for families or restaurants; infrared detection and physical detection are combined, the defects that single physical detection is greatly affected by the outside and infrared detection results are unstable are overcome, the two detection results can be verified mutually, and therefore the detection accuracy is improved.

Description

technical field [0001] The invention relates to the field of food detection, in particular to a food quality analysis and detection device. Background technique [0002] Food safety refers to food that is non-toxic and harmless, meets proper nutritional requirements, and does not cause any acute, subacute or chronic harm to human health. According to the definition of food safety by Benoy, food safety is "the public health problem that poisonous and harmful substances in food affect human health". Food safety is also an interdisciplinary field that focuses on ensuring food hygiene and food safety in the process of food processing, storage, and sales, reducing hidden dangers of disease, and preventing food poisoning, so food safety is very important. [0003] On the one hand, traditional food testing relies on experienced manual visual inspection, which has large detection errors, large individual differences, and strong subjectivity; while traditional instrumental testing g...
