The detection pipe is safe and convenient in process, safe and reliable to use, low in consumption due to the fact that no instruments or auxiliary devices are required, accurate in detection result, high in repeatability, simple and quick in sample processing method, quick in result and easy in result judgment, thereby satisfying quality monitoring of food by national relative law-enforcing departments.
Description
Technical field
The utility model belongs to the food safety detection technical field, the freshness of fast detecting rice.
Background technology
Rice is one of primary raw material of China resident meals, and rice will carry out metabolism slowly inevitably as a lived live body in storage.Simultaneously, receive the influence of microorganism and storage condition, a series of physiological change can take place in rice itself; The degree of order of macromolecular substances increases; Acidity increases, and loses the distinctive fragrance of new rice and produces stink, and possibly produce harmful material such as aflatoxin etc. because of mould contamination.The rice of boiling is loose, the rice of viscosity decline-this moment is the ageing rice.Heating, stomachache, vomiting and anorexia can appear after the edible aflatoxin-contaminated serious ageing rice; The performance of toxic hepatic diseasies such as hepatosplenomegaly, hepatalgia, skin and mucosa xanthochromia, ascites, edema of lower extremity and dysfunction of liver appears in severe patient in week at 2-3; Also cardiac dilatation, pulmonary edema possibly appear, even symptom such as spasm, stupor.
Because inevitable ageing process takes place rice, national food department is divided into three kinds of new grain, grain in storage for years and grains in storage for years with rice.Rice then belongs to new grain; For the first time the storage life surpass 1 year be grain in storage for years; Storing the rotten grain in back is grain in storage for years, and grain in storage for years should not be directly edible as grain ration.National regulation, grain in storage for years can only be by inch of candle mode to specific feed processing with brewage enterprise's directed marketing, and strictly use by regulation, profiteering, par transfer, the behavior that changes use without authorization all are illegal activities.
Detect rice whether the main detection index of " ageing " be: fatty acid value, viscosity, trial test score value and color and luster smell.Wherein there is an index reach " ageing " regulation in three of the fatty acid values, viscosity, trial test score value, promptly regards as " grain in storage for years "." GB/T 20569-2006 paddy storage quality decision rule " aspect such as judged in color and luster, smell, fatty acid value, boiling the criterion and the method for rice new-old degree all made relevant provisions.
Chinese scholars has been done a large amount of research to the rice freshness method of inspection; Detection method comprises guaiacol reaction method, guaiacol-p-phenylenediamine (PPD) and usage, drop value determination method, fatty acid value determination method, gelatinization viscosimetry or acidity indicator method etc.; There is the new old dyeing method of inspection of pair grain in China in the appendix A of grain, the oil plant check color and luster of promulgation in 1985, smell, taste identification method, wherein stipulated three kinds of analytical approachs: guaiacol reaction method, guaiacol-p-phenylenediamine (PPD) and usage, acidity indicator method.
The rice cultivated area of China is big, the zone is wide, wide in variety; In the detection of rice new-old degree; Need to study the device and the method for the new-old degree detection that is fit to China's rice,, need simple more, quick and convenient especially for the daily detection of on-site law-enforcing personnel.
The utility model content
In view of this, the technical matters that the utility model will solve is to provide a kind of detector tube of fast detecting rice freshness, detects the freshness of rice simply, quickly and easily.
For solving the problems of the technologies described above, the technical scheme of the utility model is achieved in that a kind of detector tube of quick test rice freshness, comprise storing reagent the reagent cap, be printed on the transparent detection reaction pipe and the valve body piston of scale; Said valve body piston connects reagent cap and reaction tube, and the reagent in the reagent cap is sealed and water conservancy diversion.
Further, be provided with the fine duct of perforation in the said valve body piston, this fine duct first end extend in the reagent of reagent cap, and second end stretches in the reaction tube.
Further, the material of said reagent cap and valve body piston is tygon, polystyrene, polypropylene, PVC or ABS plastic.
Further, the material of said reaction tube and fine duct is tygon, polystyrene, polypropylene, PVC, polyamide-based, polycarbonate, polyesters, polyphenylene oxide, polymethylmethacrylate or polyurethane.
The technique effect that the utility model reaches is following: 1. the integrated encapsulation of reaction reagent, testing process safety, convenient; 2. avoid operating personnel directly to contact chemicals, safe and reliable; 3. reagent cap, valve body piston, the multi-functional design of fine duct assembly need not to use any instrument and utility appliance, consume low; 4. accurate quantitative reaction reagent and sample, testing result is accurate, and repeatability is high; 5. sample treatment is simply quick, quick, the judgement easily of result; 6. the detector tube deft design is unique, good looking appearance; 7. highly sensitive, satisfy national examination criteria requirement.8. satisfy relevant law enforcement agency of country, like the administration for industry and commerce, hygiene department, quality supervision department, commodity inspection and epidemic prevention department etc., to the monitoring of food quality.

Fig. 3 is the decomposing schematic representation of the pick-up unit of the utility model fast detecting rice freshness.
Embodiment
Like Fig. 1-shown in Figure 3, be the detector tube 1 of the utility model quick test rice freshness, the reagent cap 11 of storing reagent, be printed on the transparent detection reaction pipe 12 and the valve body piston 13 of scale; The valve body piston connects reagent cap 11 and reaction tube 12, and the reagent in the reagent cap 11 is sealed and water conservancy diversion.Be provided with the fine duct 14 of perforation in the valve body piston 13, these fine duct 14 first ends extend in the reagent of reagent cap 11, and second end stretches in the reaction tube 12.
The material of reagent cap 11 and valve body piston 13 is tygon, polystyrene, polypropylene, PVC or ABS plastic.The material of reaction tube 12 and fine duct 14 is tygon, polystyrene, polypropylene, PVC, polyamide-based, polycarbonate, polyesters, polyphenylene oxide, polymethylmethacrylate or polyurethane.
The assembling of the detector tube 1 of the utility model quick test rice freshness is following:
