Description
Technical field
In a kind of chilli products, tonyred device for fast detecting and method belong to the food security field, are specifically related to the tonyred detection field in chilli products.
Background technology
" tonyred " is a kind of chemical staining agent, not food additives.Contain a kind of compound that is naphthalene in its chemical analysis, this material has azo structure, because the character of this chemical constitution has determined that it has carcinogenicity, the liver kidney organ of human body is had to obvious toxic action.Tonyred belongs to the chemical industry coloring agent, is mainly used in oil, machine oil and other some industrial solvents, and purpose is to make it hyperchromic, also adding lustre to for footwear, floor etc.
Tonyred has I, II, III, IV numbers four kinds, through toxicologic study, shows, tonyred has mutagenicity and carcinogenicity, and tonyred (No.) manifests characteristic that may be carcinogenic in human hepatocytes research, in China, bans use of in food.
Yet, on March 4th, 2005, the Heng Shi thick chilli sauce is detected first in Beijing and contains " No. one, tonyred ".In 1 month, in the product that comprises many food and drink such as KFC, food company, in succession be detected and contain " No. one, tonyred ".The tonyred event sweeps across China, and on April 5th, 2005, State General Administration for Quality Supervision announces the food that to national part provinces，municipalities and autonomous regions, may contain tonyred again and carries out finding after special examination, and the 88 kinds of food and the adjuvant that have that 36 enterprises produce contain tonyred.In mid-January, 2007, State General Administration for Quality Supervision issues the tonyred notice of warning again, and 1/4 chilli products sampling observation is defective, and all contains tonyred in these substandard products.Because tonyred has carcinogenicity, so this thing all caused very bad impact to entire society, even caused the fear of some citizen to food security.
Therefore, in order effectively to avoid tonyred, add in food, need to do strict supervision and management to whole food service industry, need to the food that may contain tonyred be endured strict scrutiny.
Tonyred detection means in advance has standard method of test, it is high performance liquid chromatography, the method can detect the particular type of the tonyred of adding in food, and the accurate content of every type, but this mode needs professional and professional equipment just can complete, and makes this detection method not to be generalized to civilian.
The patent of invention that Qu Mingyang declares " a kind of method that whether contains tonyred in fast detecting chilli products ", application number: 200910183969.6, the method for quick of tonyred is disclosed, the method is simple, is applicable to the whole people and promotes.But because whole process manually completes, and adopt the subjective judgement mode, so the testing result poor reproducibility, affected greatly by subjective judgement.
