Edible oil quality testing system

Abstract

The invention discloses an edible oil quality testing system which comprises an air inlet device and a detection device, wherein the air inlet device is used for enabling edible oil to volatilize smell; the detection device is used for detecting components of the edible oil; the air inlet device comprises a sealed container for containing the edible oil, an air inlet tube, a first air guide tube and a constant-temperature water bath tank; the detection device comprises an air chamber body, a sealing cover for sealing the air chamber body, and a detection circuit board on the sealing cover; the detection circuit board comprises a gas sensor array, a signal processing module, a control module, a storage module and a touch display module. By adopting the technical scheme, a plurality of gas sensors are adopted to detect volatile edible oil gases, so that the quality of edible oil can be rapidly and accurately tested; meanwhile, due to the selection and the arrangement of the gas sensors and design such as a small-sized sealed air chamber, the testing precision is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of oil electronic detection, in particular to an edible oil quality detection system. Background technique [0002] Oil is the first food, and edible oil is a necessary consumer product for people to make delicious food. It provides rich nutrition and fatty acids in daily diet, improves the color, flavor and shape of dishes, and increases appetite. Nowadays, various edible oils such as peanut oil, soybean oil, sesame oil, and camellia oil are emerging in the market, which enriches people's choices, but also brings troubles to people. At the same time, the edible oil produced by various manufacturers in the market at this stage Quality varies, and most consumers lack the scientific understanding of cooking oil to truly ensure the quality of the cooking oil they buy. Good cooking oil will certainly bring benefits to the human body, but the damage caused by inferior cooking oil to the human body is immeasurabl...

Nowadays, various edible oils such as peanut oil, soybean oil, sesame oil, and camellia oil are emerging in the market, which enriches people's choices, but also brings troubles to people. At the same time, the edible oil produced by various manufacturers in the market at this stage Quality varies, and most consumers lack the scientific understanding of cooking oils to truly ensure the quality of the cooking oils they buy

Good cooking oil will certainly bring benefits to the human body, but the damage caused by inferior cooking oil to the human body is immeasurable

[0003] In the detection of edible oil quality in the prior art, although the methods are various, they are difficult to be generally applied to ordinary consumers.

At present, the most accurate quality detection method of edible oil is chemical analysis method, which can conduct quantitative and qualitative analysis on the components of edible oil, and directly judge the content of harmful substances in the sample and whether it is of high purity and high quality through the content of components. Oil, but its test time is long, the cost of the equipment used is high, it can only be carried out in some special laboratories, and it is difficult to promote it to the public

There are also some commonly used detection methods such as physical and chemical detection methods, which are mainly aimed at the fact that some inferior oils (such as waste oil) have higher acid value, iodine value, more oxidation products, and more Differentiate between metal ions, etc., use chromatography, colorimetry and other analysis methods to judge the quality of edible oil. This method has a high accuracy rate for the detection of secondary edible oil, and the detection time is relatively short, but the scope of application is very large. limitations

In addition, there are some detection methods that directly look at the appearance and add common reagents to separate the mixed oil. With the advancement of edible oil adulteration and the continuous improvement of edible oil pressing methods, it has become no longer applicable.
