Abstract
The invention relates to a pork freshness testing method, and in particular relates to a quick pork freshness nondestructive testing method based on a gas sensor technology. The method can be used for judging the freshness of the pork by pork smell collection and a mathematical model. According to the analysis method, a knowledge base which is established in advance is used for comparison, so that the pork freshness degree can be rapidly obtained; the method can be used for assisting or replacing professional testing personnel, so that the artificial subjective factors are eliminated, and the pork freshness can be accurately judged.
Description
Technical field
The present invention relates to a kind of pork freshness detection method, especially a kind of fast non-destructive detection method of the pork freshness based on gas sensor technology.
Background technology
China Shi Yige pork big producing country, along with improving constantly of people's living standard, the consumption figure of pork is increasing year by year.Consumer no longer rests on quantitatively for the concern of pork simultaneously, and more pays close attention to its quality.But China's Pork Market is still lack of standardization at present, various quality security problems happen occasionally, and consumer's health has been caused to adverse effect.In order to ensure consumer's safe diet, the detection that pork freshness is carried out to science health has more and more been subject to country and the numerous common people's attention.
From the chemical analysis angle of meat, the volatile compound that its aroma compound shows fragrance aspect has lipid oxidation product, carbonyls, nitrogen-containing products, amine, ammonia, thio-alcohol, sulphur products, sulfuration organism, sulfide etc.When meat is because the pollutions of various microorganisms and effect have caused corruption or because the decomposition of self enzyme causes sour smelly property fermentation, emitted sulfuretted hydrogen and other volatile matter.
The content of total volatile basic nitrogen (TVB-N) is exactly one of the important indicator of the detection freshness of meat of state food rules regulations, it is that animal food is because of the effect of enzyme and bacterium, in decay process, protein is decomposed and the alkaline nitrogen substances such as generation nitrogen and amine.TVB-N and freshness of meat have close relationship, have national standard to comply with.Organoleptic indicator and the freshness of meat of meat have substantial connection.Organoleptic indicator, the definite smell that says, is mainly by ammonia (NH
3), sulfuretted hydrogen (H
2, VOC(organic volatile) etc. S) releasing degree of smell determines, can know ammonia (NH
3), sulfuretted hydrogen (H
2s) and VOC(organic volatile) releasing degree just and between TVB-N exist certain mapping relations, as long as obtain this mapping relations, so just can be from one group of ammonia (NH
3), sulfuretted hydrogen (H
2s) value, VOC(organic volatile) is obtained TVB-N value, has so just drawn the freshness of meat.
At present, the method of pork being carried out to freshness judge according to the organoleptic standard of national defined is mostly traditional TVB-N pH-value determination pH method, and traditional TVB-N pH-value determination pH method needs just can complete for tens of minutes consuming time mensuration, length expends time in, efficiency is low, and due to time lengthening, the factors such as manual operation error, the degree of accuracy of detected pork freshness also can decrease.
Summary of the invention
Object of the present invention is exactly to improve traditional TVB-N pH-value determination pH method, proposes a kind of pork freshness fast non-destructive detection method based on gas sensor technology, and the method can shorten detection time, and gets rid of artificial subjective factor, the freshness of objective judgement pork.
A kind of pork freshness fast non-destructive detection method based on gas sensor technology of the present invention, has comprised that pork smell gathers and mathematical model is differentiated two steps, it is characterized in that concrete detection comprises the following steps:
(1) sampling
Pork sample is got A, B, and tri-parts of C, point, detects and gathers related data information to three samples under same climatic environment at one time;
(2) set up knowledge data base
Knowledge data base is judged database by analytical database and expert and is comprehensively formed, and these two databases are point at one time, under same climatic environment, pork sample is detected respectively, wherein,
Chemical composition analysis report forms analytical database, measures the content of total volatile basic nitrogen in pork sample A with GB/T5009.44-2003 semimicro nitriding;
By professional, judge report and forms expert and judge database, by professional, by sense organ, comprise that sense of smell, sense of touch and vision judge pork sample B, determine that fresh, inferior fresh and corrupt rank report formation expert judges database;
(3) image data
Tested pork sample C smell is carried out to data acquisition, and the collection of pork smell gathers by Gas Sensor Array sensor, and this part harvester comprises gas sensor array part, signal condition part and part of data acquisition; Use gas sensor to carry out data acquisition to gas odorousness, gas sensor is electrochemical sensor, by carrying out work to the electric signal that tested gas reacts and generation is directly proportional to gas concentration;
Described gas sensor specific works mode is: the collection of pork odorousness gathers by Gas Sensor Array sensor, gas sensor is converted to electric current output by odorousness, output current filters after disturbing pulse signal by signal condition, import the A/D data acquisition module that sets in advance frequency acquisition (10Hz) into, computing machine records gas sensor group ammonia (NH by A/D data acquisition module
3), sulfuretted hydrogen (H
2s) the current value sampling and in VOC sensor 10 minutes, and deposit in database, the eigenwert of the odorousness data that now the digitized current value data in database are exactly sample C;
(4) set up data model
By the stink damp, ammonia and the VOC(organic volatile that gather) eigenwert and knowledge base compare, utilize SPSS data analysis software to carry out variance analysis, correlation and regression analysis to characteristic value data and knowledge base data, set up the data model of matching regression equation;
(5) detect
Stink damp, ammonia and the VOC(organic volatile of the pork sample that needs are detected) value carry out data acquisition, utilize the data model of having set up, calculate the content of total volatile basic nitrogen, thereby detect the freshness of pork sample.
The regression equation obtaining according to matching is analyzed known, in fresh, inferior fresh and corrupt each grade of pork, the value of total volatile basic nitrogen (TVB-N) and stink damp, ammonia and VOC(organic volatile) eigenwert, all there is near linear regression relation, therefore, can, according to by measuring the current value of the associated gas volatilization concentration of pork, utilize near linear regression relation, just can calculate the content of total volatile basic nitrogen, thereby draw fast corresponding pork freshness.
The present invention is based on the method for the pork freshness quick nondestructive detection of gas sensor technology, gathered stink damp, ammonia and VOC(organic volatile) there is the gas of substantial connection with pork freshness, then formed data model, and contrast with knowledge base, according to analytical database, draw three kinds of values that detect gas, by expert, judge database and make the differentiation of making pork freshness.The knowledge base that this analytical approach utilization establishes is in advance compared, and can draw more fast pork freshness, assists or replaces professional testing staff, gets rid of artificial subjective factor, more accurately pork freshness is passed judgment on.
