Problems solved by technology

At present, there is a lack of an effective method for detecting bacon in the storage process in the market. Therefore, it is of practical significance to seek a fast, simple and reliable detection method for bacon in the meat industry for product risk control and quality improvement.
As an emerging gas characterization method, color-sensitive sensing technology has been applied in the field of food and agricultural product detection in recent years, such as the patent "a method for detecting the content of biogenic amines in fish based on a storable gas sensor" (application No.: 201710535608.8) discloses a fish biogenic amine content detection method based on a storable gas sensor, but the image acquisition system used is a scanner, which cannot meet the needs of online detection
Visual color-sensing sensing technology is feasible in flavor detection of agricultural products, but the identification of bacon samples during bacon storage has not been reported

[0041] Example 2: A detection method based on visualized gas sensor array for bacon

[0042] figure 2 It is a flow chart of the invention for detecting bacon based on a visualized gas sensor array. Such as figure 2 As shown, the method for detecting bacon based on the visualized gas sensor array includes the following steps:

[0043] (1) The samples in the examples all come from bacon products of the same brand with the same shelf life. A total of 70 samples of bacon samples with different storage times were collected. The bacon was cut into 3cm×3cm×2cm squares with a sterile knife, and the thickness of the sample was kept as uniform as possible. The samples were stored at a constant temperature of 37°C for a total of 30 days. Take 10 samples every 5 days to collect visual gas-sensing images, and test their sensory and volatile odor indicators.

[0044] (2) Preparation of gas-sensing sensing array: Aiming at the volatile gas components produced in the bacon lipid oxida...

Abstract

The invention discloses a detection device and method for hardard bacon based on a visualized gas-sensitive array, and relates to the technical field of quality detection of agricultural and livestock products. Aiming at the problem of lack of change detection technology in the current bacon storage process, the present invention provides a system and method for detection of bacon based on a visual gas sensor array, which has the characteristics of fast, non-destructive, and visualization, and can realize the change of bacon during storage Rapid detection of samples. This method detects the characteristic volatile gases of hardard bacon, screens the corresponding gas-sensing materials, and constructs a gas-sensing sensing array. The image before and after the reaction of the sensor array is obtained by the image acquisition device, and the gray average value of each channel of each sensitive unit in the sensor array before and after the reaction is used for feature extraction, which is the odor feature matrix of the tested sample. A discriminant model is built based on the feature matrix to detect the degree of change of bacon in real time.

Description

technical field [0001] The invention relates to the technical field of quality detection of agricultural and livestock products, in particular to a detection device and method for hardard bacon based on a visualized gas-sensing array, which can quickly detect hardy bacon during storage. Background technique [0002] Bacon has a traditional Chinese characteristic flavor and is one of the traditional Chinese famous products. Because of its uniqueness and high-quality flavor, it has experienced thousands of years of historical changes without decline, which proves that it has a broad foundation and also shows that it contains Huge development potential. In the era of rapid development of modern science and technology and productivity, bacon, a food that is convenient, fast and conducive to secondary processing, is becoming more and more popular. However, some shortcomings of bacon also hinder its further development. Generally speaking, the raw meat of bacon It is basically fa...
