Description
Technical field:
The present invention relates to a kind of method of identifying waste oil and swill oil by detecting the mark add, belong to the food safety Regulation field.
Background technology:
Edible oil is essential thing people's every day, is divided into vegetative grease and animal raw fat.Edible oil enters in human body as the part of vegetable in diet, the nutritional labeling that needs through becoming human body after digesting and assimilating.But the waste grease that produces in diet is a lot, and the waste grease in resident family and little shop, curbside enters in trench, and the waste grease in big-and-middle-sized restaurant enters oil-water separation tank, also has during a large amount of waste greases enters swill with leftovers in each restaurant.From low-carbon economy and environmental angle, the kitchen frying of eating in addition in trench, in oil-water separation tank, in swill is carried out harmless treatment with the old oil of crossing and carried out commercial Application is that part is meddlesome, if but be antihygienic with above-mentioned waste grease through directly turning back to dining table after refining.Have the expert to think that its harm shows two aspects: the one, edible oil is high-temperature heating repeatedly, the grease molecule has cracking certainly, some compositions wherein can change, reuse is problematic certainly, next is that waste oil and swill oil source are not clear, produce in making or to add which kind of poisonous and harmful substance unknown, its feature is difficult to judge.
According to report: China has 3,000,000 tons " waste oil " to flow into dining table every year.Edible oil is safely the basis of food security, how to prevent that waste oil and swill oil from returning to the problem that dining table is food safety Regulation department and public attention.Adopts measure has two kinds now, the one, make great efforts to build the permanent mechanism that kitchen castoff is disposed management, use modern means of science and technology to solve the emission treatment problem of kitchen castoff, promote energetically the processing power of dissolving of kitchen castoff, realize short haul distance, closure, resource and harmless treatment.The 2nd, organize the expert to carry out the detection technique tackling key problem with regard to edible oil backflow secondary refinement behavior.
From existing report, existing state compulsory standard " edible vegetable oil hygienic standard " (GB2716-2005) in, detect about the physical and chemical index of edible oil comprise that acid value, peroxide value, leaching oil solvent are residual, free phenol (cottonseed oil), total arsenic, lead, aflatoxin, benzopyrene, residues of pesticides totally 9 indexs, respectively plant crude oil and vegetable edible oil are carried out different standard detection.The expert claims, these 9 basic edible oils detection indexs in standard, and also all possibility is qualified even produce from waste oil the oil that comes, and can't go the property distinguished detection for waste oil at all.
Therefore, national correlation department has been studied and defined the waste oil detection method and has openly been collected technology and discussion scheme, has also formed detection method and has proved expert group, and the method for inspection of correlation technique mechanism research and development is carried out scientific appraisal.5 kinds of waste oil detection method specificitys that collection is at present arrived are not strong, and specificity does not refer to by force which is not told well is waste oil, and which is edible oil.So the method that collection is arrived still can not be as effective judging means of waste oil.Simultaneously, show according to related data, from the countries in the world situation, waste oil there is no the detection technique of special efficacy at present.
Also have the expert to think, even inspection body has determined the test rating of waste oil, the fake producer will try every possible means to cover the project that will detect, and they also can improve constantly the manufacture craft of waste oil by technological means, and detection difficulty is increased.In particularly adding waste oil and swill oil to normal oil according to different proportionings when improving manufacture craft, more can make new detection method helpless.
Summary of the invention:
The object of the present invention is to provide a kind of method of identifying waste oil and swill oil by detecting the mark that adds, with the mark of determining regularly add in trench with fixing a point, in the oil-water separation tank in big-and-middle-sized restaurant, in the swill in each restaurant, detect by efficient detection method the mark that adds again, prevent that waste oil and swill oil from returning to dining table again, also can supervise the whereabouts of waste oil and swill oil simultaneously.
