The detection process of using the reagent kit is wholly completed in a plastic tube, with small amount of samples and reagents. The waste fluid and plastic tube can be recycled, so as to prevent and reduce the secondary pollution. The utility model has the advantages of sensitive detection, accuracy and convenient operation, which applies to on-site rapid detection and can be used to detect a plurality of harmful substances in the food, such as sulfur dioxide, hydrogen peroxide, nitrite, nitrate, borax, formaldehyde, rongalite, fresh rice, old rice, sucrose in the bee honey, sesame oil purity, iodine in the salt, total acid in the food, amino-acid nitrogen in the soy sauce, peroxide value in the food and the urea content in the food.
Description
Technical field
The utility model relates to a kind of portable, sensitive, quick detection kit, is specifically related to a kind of food security quick detection kit that on-the-spot rapid semi-quantitative detects the food poisonous and harmful substance content and the Multi-parameter Combined Tool of the use adjuvant that exceeds standard that is used for.
Background technology
Along with the deepening continuously and develop of economical operation globalization, food-safety problem more and more receives the concern of national governments, international organization, industry organization, industry specialists and even general public.Ensuring food safety becomes the basis that ensures existence and protection human life health, becomes the basis of improving economical operation and human life quality.Simultaneously, the Fast Detection Technique that ensures food safety obtains the great attention of each relevant departments too, and a lot of method for quick also are included into each national standard method.The objectionable impurities kind that food security relates to is a lot, and the utility model mainly detects in sucrose in sulfur dioxide in food, hydrogen peroxide, nitrate, nitrite, borax, formaldehyde, sodium formaldehyde sulfoxylate, Xin Mi and old rice, the honey, sesame oil purity, the salt in iodine, the food in total acid, the soy sauce content of urea in amino-acid nitrogen, food peroxide value and the food.
Sulphuric dioxide has discoloration on the one hand, can bleach food, and sulphuric dioxide has reducing action on the other hand, can suppress oxidasic activity.As food additives, it is widely used in the food.As the preservative treatment of dried fruit, preserved fruit, the fresh-retaining preserving of fruit grape, mushroom to protect look anticorrosion etc.The long-term edible food that contains excessive sulphuric dioxide can not only destroy vitamin B1, can also make calcium form insoluble substance, influences the absorption of human body to calcium.Simultaneously, sulphuric dioxide is met water and is generated sulphurous acid, and people's stomach and intestine are had spread effect, if what use is industrial sulphur, also serious intoxicating phenomenon might take place.
Hydrogen peroxide has strong oxidisability, as the production and processing auxiliary agent, has disinfection, functions such as bleaching.Can there be huge potential threat in the medium-term and long-term residual excessive hydrogen peroxide of food to health.
After adding borax in the food, can make food color beautiful, seeming can be fresher, the softer cunning of quality, and the toughness height boils for a long time and does not stick with paste.Borax is not a kind of mutatis mutandis antiseptic in fact, and borax can make the people produce toxicity symptom, comprises nauseating, vomiting, bloody flux and stomachache.Baby and child are easier to be subjected to the borax toxic effect, even serious meeting is to cancer.
Nitrite can be oxidized to methemoglobin to the low Ferri-hemoglobin that carries oxygen in the blood, thereby causes the toxicity symptom of anoxic, makes people's heartbeat accelerate dizziness and nausea, digestive discomfort.In addition, nitrite and nitrate can be converted into nitrosamine in human body, and nitrosamine is a kind of carcinogen, and is very big to human health damage.
Formaldehyde is the protoplasm material that a kind of toxicity is very strong, destroy biological cell protein, can cause illness such as human allergy, enteron aisle irritant reaction, food poisoning.Formaldehyde is that country prohibites the non-food stuff adjuvant that adds in the food.Eat the food that contains formaldehyde and can directly produce toxic reaction, the lighter's dizziness, cough, vomiting, Upper abdominal pain, stupor, shock can appear in weight person; Formaldehyde is to the intense stimulus effect of people's skin and respiratory apparatus mucous membrane, and to the central nervous system of human body, especially there are strong effect in the organs of vision, bronchus and lung; The mucous membrane of damage people's oral cavity, pharynx, esophagus, stomach.
Sodium formaldehyde sulfoxylate (chemical name is a rongalite) has reducing action, at the industrial bleaching agent that is used as.Country expressly provides, forbids sodium formaldehyde sulfoxylate is used for food.Can cause pulmonary edema after edible, liver, the nephremia and blood vessel peripheral edema also have certain influence to optic nerve, are a kind of potential carcinogenic substances.
Old rice is because the two ends jaundice of making moist illustrates that this rice has produced aflatoxin owing to go mouldy.Aflatoxin is one of serious carcinogen.
Current, the phenomenon that honey is mingled is serious, and according to investigations, in the honey of basic unit purchase, in the sample of mingling of appearance, in the sample that sucrose is mingled, the content of sucrose is many between 10-28%, have in addition up to more than 50%.The degree of becoming sour of acid value and peroxide value reflection grease is the main sanitary index of sesame oil product, and its value is high more, and it is just serious more to become sour.The grease that becomes sour can cause human intestines and stomach's discomfort, and the body enzyme system is had detrimental effect, and some product that becomes sour has carcinogenesis.
Lack iodine and can cause thyromegaly, children's iodine deficiency can cause IQ low.Preventing and treating IDD (Iodine deficiency disorders) with iodized salt is a kind of good method of generally acknowledging in the world at present.There is the danger of iodine hyperthyroidism in edible iodized salt greater than Sq to the crowd of iodine sensitivity.
Total acid is meant non-dissociated acid in the food and the concentration sum of the acid that dissociated.Usually represent with the percentage concentration of certain representational acid, represent with citric acid as the total acid result in the dry fruit food product.Its total acid mainly exists with organic acid (malic acid, tartrate etc.) form, if total acid is too high, illustrates that product might become sour and can not eat under microbial action.
Amino-acid nitrogen is one of characteristic index of soy sauce, refers to the content of the nitrogen element that exists with amino acid form.It has represented the height of amino acid content in the soy sauce.Amino acid nitrogen content is high more, and quality of soy sauce is good more, and delicate flavour is dense more.In industry standard, the quality of soy sauce grade mainly is to determine according to the content of amino-acid nitrogen in the soy sauce.
Peroxide value is meant the mM quality of superoxide in the 100 gram greases.Peroxide value is to weigh the become sour important sanitary index of degree of Food Oxidation, and the grease in the food is hydroperoxides at the product of oxidative rancidity initial period, and being reflected on the sanitary index is the increase of peroxide value.
Urea is unallowed as food additives, and there is potential threat in the long-term edible food that contains urea to health.
Objectionable impurities in the above food has all had a strong impact on people's normal life, and it is very necessary field quick detection to go out these content of harmful, and existing detection means generally only limits to laboratory operation, can not on-the-spot test; Existing on-the-spot detection means also just is confined to the detection of single parameter, and at present, method and the kit that Multi-parameter Combined Tool is applied to field quick detection together appears in Shang Wuke.
