Abstract
A color atla for determining pork freshness and a manufacturing method thereof belong to the technical field of foods quality detection. The color atla is characterized in that a rectangle plastic hard card has a size similar to an identity card; a color gradient strip near 13mm wide is parallel to a long edge on a right side of the hard card and is a color strip used for pork freshness color contrast; and a back side has instructions and attentions. The manufacturing method includes steps of: selecting lean meat with a palm size section from fresh pork; shooting a picture; inputting the picture into a computer equipped with a piece of toning software and adjusting to single colorimetry; arranging along the long edge of the rectangle plastic hard card continuously according to sequence. The invention has active effects that a selection reference for determining pork freshness for residents is provided, and conditions for residents to buy safe pork are created; besides the color atla can prevent the pork suppliers from falsification and using inferior as superior, so as to facilitate healthy and benign development of food industry.
Description
Technical field
Belong to food quality detection technique field, exactly relate to the technology of charcuterie quality fast detecting.
Background technology
At present, whether fresh, generally can only distinguish with feeling according to checking the pork outward appearance if distinguishing pork when the resident buys pork.The judgement of not having standard like this is prone to cause distinguishes mistake, and the resident can't know pork freshness accurately in addition, therefore, can't buy safe, relieved pork.
Summary of the invention
The present invention provides a kind of resident of allowing can provide judge pork freshness foundation a kind of to be used to measure the colour atla of pork freshness and its method for making to the pork of being bought.
The technical scheme that the present invention takes:
A kind of colour atla that is used to measure pork freshness; Comprise the vitta that is used to contrast; Its scheme is: with the similar rectangle polymer hard card of I.D. size; At the positive Chang Bianchu of hard card; With the parallel color gradient that nearly 13mm is wide that distributing in long limit, be used for vitta with the pork freshness color contrast; Operation instruction and points for attention are arranged overleaf.
A kind of method for making that is used to measure the pork freshness colour atla, implement by following operation steps:
1) selects the fresh pork of the famous pork brand in market for use, get sandwich, fillet position or back leg, arrange the lean meat in hand size cross section, position greatly; Said famous pork brand is Shuan Hui, Yu Run, gloomy, the five rich foods of going up of love;
2) xsect of getting meat is a shooting picture: adopt fixed lens, aperture, speed, illumination; Xsect to above-mentioned all kinds of meat is taken pictures respectively at the set time point;
3) take the back at every turn wrap pork with preservative film and put cold compartment of refrigerator, for next time point for shooting,
4) the same time is imported the computer that toning software is housed to the cross section meat photograph of different parts shooting, and the multiple yellowish pink merging tone of taking by the same time is single colorimetric; The single colorimetric that each time point is merged is arranged on the rectangular edge of rectangle polymer hard card according to the order of sequence continuously;
5) said set time point is the 1st time point for the fresh pork of just having slaughtered, and the 2nd day same time was the 2nd time point, and the 3rd day same time was the 3rd time point, and the like, up to the 7th time point.
Good effect after the embodiment of the present invention is:
For the resident provides the selection foundation of judging the pork freshness when choosing fresh pork, easy to use; There is not basis for estimation when having avoided the resident to buy pork.The resident of being embodied as of the present invention has bought safety, relieved pork has been created condition; Also can play on the other hand and stop that the cut of pork merchant practises fraud, the situation of substituting the bad for the good successively occurs, help a power to healthy, optimum direction on developing at field of food.
Embodiment
Domestic live pig principal item is long white at present, big Yorkshire, and Du Luoke, Pietrain etc., the characteristics of these pigs are that feedstuff-meat ratio is high, and growth cycle is short, and premunition is strong, and lean meat percentage is high; Processing technology according to domestic existing pig slaughtering; Can cause same pig to change slightly in the yellowish pink of the different parts of trunk; Because most meat producing plants all are to adopt the form of reversal of the natural order of things to butcher; It is yellowish pink dark than the back leg part to cause the pig front leg portions to divide; So we are divided into 2 to colour atla, promptly light color is that meat and dark color are meat.
Select for use love gloomy, the five rich fresh porks of going up food, main position is sandwich, back leg, the big lean meat of arranging, the xsect of getting these meat is a shooting picture.True in order to ensure shooting effect adopted close-up, and fixed aperture, speed are bought back after the meat, clap picture for the first time at once, and this is the freshest; Take back wrapping and put cold compartment of refrigerator, continued to take in second day with preservative film; Continuing the company of shooting then on the 3rd day clapped 7 days.Every bat is intact once, and printing effect figure and meat are compared immediately.Because the relation of shooting time, in shooting process, consider pork at room temperature yellowish pink have certain variation, therefore, constantly compare shooting effect and correction in time with fresh meat, the same up to color.The meat of each brand is arranged in chronological order; Be merged into progressive colour band and stick on long 9cm according to pig kind and different classification of butchering technology; On the wide 5.4cm card; Be made into the colour atla of pork freshness; Use the gradual change colour band that is made into when buying pork; The comparison pork colour is confirmed pork freshness.
Color on the gradual change colour band is represented the freshness of pork.Colour band is divided into 7 different colours, from first day, by second day, the 3rd day ... .. by that analogy, up to the 7th day; In order to differentiate the freshness of pork.
The present invention can detect the fresh situation of pork very convenient and accurately, and the colour atla of pork freshness can be carried; The resident just can buy safe, relieved pork.
