Description
Technical field:
The invention belongs to the freshness of meat detection range, be specifically related to a kind of meat product freshness portable detecting device.
Background technology:
China is meat product production and consumption big country, and meat product often will experience multiple storage methods such as freezing, refrigeration from butchering dining table, and the detection of meat product freshness is the focus that people pay close attention to always in the storage.Studies show that spoilage organisms is the major reason that causes that the meat product freshness descends.Spoilage organisms is nutriments such as the protein in the continuous consumption meat product, carbohydrates, fat in growth, reproductive process, and discharge escaping gases such as sulfide, amine.The meat product of different grade of freshness often discharges the characteristic escaping gas, and in daily life, the people can apply one's nose to and hear the smell that food gives out, and roughly judges the freshness of food.Utilize this characteristics, the scholar has proposed the meat product freshness detection method based on gas chromatography-mass spectrography (GC/MS), differentiates the meat product grade of freshness by the variation of analyzing meat product volatile flavor composition.Though the testing result of GC/MS is accurate, very high to instrument and equipment and operating personnel's requirement, the testing process time and effort consuming can not adapt to the extensive online detection of meat product freshness.
Visual gas sensor technology is a kind of gas fast detecting new method that occurs in recent years, and it utilizes in the gas sensor characteristic of color generation significant change before and after the gas sensitive and gas reaction to be measured, and gas to be measured is carried out qualitative and quantitative analysis.Patent of invention " a kind of method and device based on the visual detection of sense of smell fish freshness " (application number: 201010262347.50) disclose the visual method that detects the fish freshness of a kind of sense of smell, this method is with the gas sensitive as sensor such as porphyrins, PH indicator, chromotropic dye, the gas that fish is volatilized contacts with sensor, obtain the image information of sensor and fish escaping gas reaction front and back by scanner, and the characteristic information that utilizes computing machine to extract in the image is used for judging the fish grade of freshness.Compare with the GC/MS detection method, the sense of smell visible detection method has characteristics such as speed is fast, visual result, but these class methods also have some shortcomings: the visual pick-up unit of (1) sense of smell is very complicated, generally need use compressed air tank, scanner, computing machine etc., the cost height, and the non-constant of the movability of whole detection system is difficult to the requirement of satisfying the food freshness scene, detecting in real time; (2) gas sensitive in the gas sensor is porphyrins, hydrophobicity pH indicator, chromotropic dye etc., need to use toxic solvents such as chloroform, chlorobenzene in its manufacturing process, make food with lost edible and sales value after gas sensor contacts.
Summary of the invention
The object of the present invention is to provide a kind of meat product freshness portable detecting device, under the prerequisite that does not influence the edible and sales value of pork, simplification device, realize freshness of meat fast, detect, reduce the detection system cost in real time.
In order to solve above technical matters, the concrete technical scheme that the present invention adopts is as follows:
A kind of meat product freshness portable detecting device, comprise handle, place handle inside accumulator, be installed on handle one end the intelligent miniature camera, be installed on the handle and touch screen, the light source module that links to each other with the intelligent miniature camera by data line, the gas sensor module that is installed on the light source module front end face by coupling shaft, it is characterized in that: described light source module is installed on the front end of intelligent miniature camera lens, is made up of several led light sources and hollow cylinder light source chamber; The diameter of hollow cylinder light source chamber is greater than the diameter of intelligent miniature camera lens; Except light source module be connected with camera lens zone and light source module be connected with gas sensor module regional made by light transmissive material, make by light-proof material in other zone of hollow cylinder light source chamber; The inwall of led light source and hollow cylinder light source chamber forms an angle and is installed on the inside of hollow cylinder light source chamber, regulates the light that the size of angle between led light source and the hollow cylinder light source chamber inwall makes led light source send and converges on the gas sensor of gas sensor module.
Described gas sensor module is installed on the front end of light source module, is made up of hollow cylinder gas reaction chamber, gas passage, gas sensor array, diaphragm seal and transparent protective film; The zone that the hollow cylinder gas reaction chamber is connected with light source module is that transparent material is made, and make by light-proof material in other zone of hollow cylinder gas reaction chamber; Be provided with the some groups of gas passages that are symmetrically distributed in the side of hollow cylinder gas reaction chamber; Gas sensor array is installed on the indoor basal surface of hollow cylinder gas reaction; Before gas sensor module was enabled, gas passage was sealed by diaphragm seal, and gas sensor array is covered by transparent protective film, prevented that non-gas to be measured from contacting with gas sensitive and reduce the sensitivity of gas sensor array.
The gas sensitive that described gas sensor array uses is the natural colouring matter anthocyanin in the plant.
Described meat can be the meat of all kinds of animals such as beast, fowl, bird, fish.
The present invention has beneficial effect: the front end that light source module and gas sensor module is installed on the intelligent miniature camera lens, need not to provide the assembly of the visual detection systems of conventional sense of smell such as light-source box, computing machine, scanner, thereby simplification device, the pick-up unit conveniently moving, can realize quick, the detection in real time of freshness of meat, reduce the detection system cost simultaneously.The present invention adopts the interior natural colouring matter anthocyanin of plant as the gas sensitive of gas sensor, can not produce food in the testing process and pollute, and still have through the meat after the freshness detection to eat and sales value.
