Pay attention to food safety and stay away from health hazards
1. The water Teng Dalian flavored soda (500ml/bottle) produced by Gaizhou Tianlu Beverage Factory and operated and sold by Qianyangxiang Xiaxiahong Supermarket in Yixian County does not meet the national food safety and related standards( yeast (measured value: 3.4×10² CFU/mL, food safety standard value ≤20CFU/mL);
Yeast is a common fungus in nature and is an indicative indicator of the hygienic quality of food. The number of yeast in food refers to the number of yeast colonies formed in the 1g or 1mL sample after the food sample has been processed and cultured under certain conditions. Serious excess of yeast in food will destroy the color, aroma and taste of food and reduce its edible value. The National Standard for Food Safety in Beverages (GB 7101-2015) stipulates that the maximum limit value of yeast is 20 CFU/mL.
2. The black sesame seeds (raw dried seeds) sold by the real fresh fruit and vegetable supermarket in Linghe District do not meet the national food safety and related standards (in terms of fat, measured value: 4.3mg/g, the specified value of food safety standards ≤3mg/g);
3. The black sesame seeds (raw dried seeds) operated and sold by the Green Tiandi Fresh Supermarket in The West Inner Ring road of Heishan County, the acid price (measured in terms of fat, the measured value: 4.7mg/g, the value specified in the food safety standards is ≤3mg/g) does not meet the national food safety and related standards;
Acid valence (in terms of fat) can be used to evaluate the degree of rancidity of food. Food rancidity can produce aldehydes and ketones, and long-term intake will have a certain impact on health. Under normal circumstances, consumers can clearly distinguish that they have odors such as hara during use, and they need to avoid eating. The National Standard for Food Safety for Nuts and Seeds (GB 19300-2014) stipulates that the limit value of acid price in sesame shall not exceed 3 mg/g. The main reasons for the unqualified acid price are: the procurement of raw materials is not strict, the production process is not up to standard, the product storage conditions are improper, especially when the ambient temperature is high, it is easy to lead to oxidative rancidity of fat in food.
4. The shrimp climber (seawater shrimp) and cadmium (measured in Cd, measured value: 7.2mg/kg, the specified value of food safety standards≤0.5mg/kg) operated and sold by Zhang Xiaonan Aquatic Products Distribution Office in Guta District do not meet the provisions of national food safety and related standards;
Cadmium (in terms of Cd) is one of the most common polluting heavy metal elements in aquatic products, and the unqualified cadmium in aquatic products may be caused by the enrichment of cadmium in the environment during the aquaculture process of aquatic products. Cadmium is a very toxic heavy metal, its compounds are mostly toxic substances, industrial discharge of cadmium-containing sewage pollutes the river water and farmland, cadmium is easier than other heavy metals for crops, vegetables, rice absorbed, people eat some contaminated crops, they will enter the human body through the digestive tract, mainly gathered in the liver and kidneys and cause damage. In addition, cadmium compound particles can enter the human body through the air, cadmium damages the central nervous system of the human body very much, when cadmium poison enters the human body, it is extremely difficult to excrete, it is very easy to interfere with the function of the kidneys, reproductive function. Cadmium can also cause dysregulation of the stomach and spleen, which reduces the zinc-cadmium ratio and leads to an increase in hypertension. Because cadmium pollution has some characteristics such as long cycle and large concealment, cadmium will replace calcium in the bone, which will seriously soften the bones and break the bones. The harm of cadmium to the human body is mainly chronic accumulation, and long-term large intake of foods with excessive cadmium content may lead to kidney and bone damage.
5. Yihe twist flower (bulk weighing brown sugar flavored pastry) produced by Liyuan Food Factory in Nanpiao District, Huludao City, operated and sold by Senquan Supermarket in Taihe District, cyclamate (measured in terms of cyclohexylsulfamic acid, measured value: 3.35g/kg, food safety standard value ≤1.6g/kg) does not meet the national food safety and related standards;
The chemical name of cyclamate is sodium cyclohexylsulfamate, which is an additive commonly used in food production. Cyclamate is a commonly used sweetener, which belongs to the non-nutritional synthetic sweetener, and its sweetness is 30 to 40 times that of sucrose. Cyclamate, odorless, sweet taste, is a nutrient-free sweetener. Slightly bitter after heating. The decomposition temperature is about 280 °C, and no caramelization reaction occurs. Slightly decomposed in an acidic environment, stable when alkaline. Its concentration is greater than 0.4% with a bitter taste, soluble in water with high content of nitrite and sulfite, resulting in petroleum or rubber-like odor. It is non-hygroscopic and does not support mold or other bacterial growth. According to the provisions of China's "Sanitary Standards for the Use of Food Additives" (GB2760-2014), "cyclamate" is a legal food additive, which can be used as a sweetener, and its scope of use is: frozen drinks (except edible ice), canned fruit, curd milk, biscuits, compound seasonings, beverages (except packaged drinking water), prepared wine, and jelly The maximum use amount is 0.65g/kg; the maximum use of jam, candied cold fruits, pickled vegetables, and cooked beans is 1.0g/kg The maximum use of dehulled cooked nuts and seeds is 1.2g/kg, the maximum use of bread and pastries is 1.6g/kg, the maximum use of shelled cooked nuts and seeds is 6.0g/kg, and the maximum use of cold fruits, speech and fruit cakes is 8.0g/kg. In addition, diabetics and obese people can use it instead of sugar. The allowable daily intake (ADI) for cyclamate, established by the JOINT FAO/WHO Expert Committee on Food Additives (JECFA), is 11 mg/kgbw. That is to say, for an adult weighing 60kg, even if he eats cyclamate every day, as long as his daily intake does not exceed 660mg, it will not bring harm to the health of the human body. And because cyclamate is very sweet, it is generally difficult to achieve harmful intake through a normal daily diet. According to the perspective of food safety risk assessment, cyclamate has sufficient risk assessment results, and normal use will not cause harm to human health. As a legal additive in China, cyclamate can only be used in the preparation of wine in wine products, and the prepared wine, also known as the blended wine, is a mixed wine. If cyclamate is used in liquor, it is an over-range addition and is a violation. Different from the preparation of liquor, liquor is produced according to the traditional process, and the requirements are not allowed to add foreign substances produced by non-liquor fermentation, such as flavors, spices, and various sweeteners including cyclamate. According to China's current standards for the use of food additives, liquor is not allowed to add cyclamate.
6. The residual amount of anhydrous cake (pastry) and aluminum (dry sample, measured in Al, measured value: 133mg/kg, food safety standard value of ≤100mg/kg) operated and sold by the brothers and sisters in Linghe District does not meet the national food safety and related standards;
The residual amount of aluminum (in Al terms), jellyfish processing requires the use of a large amount of salt and alum (potassium aluminum sulfate) to salt the fresh jellyfish, so that it is dehydrated in large quantities, while playing a role in preventing jellyfish rot. According to the National Food Safety Standards for the Use of Food Additives (GB2760-2014), the maximum residue of potassium aluminum sulfate (also known as alum) and ammonium aluminum sulfate (also known as ammonium alum) in pastries is ≤100mg/kg (in Al). The main toxicity of aluminum is neurotoxicity, reproductive and developmental toxicity, and there is no carcinogenicity. Although aluminum is toxic, it is not harmful to human health as long as it is ingested, which not only depends on the content of aluminum in food, but also closely related to the amount of these aluminum-containing foods and the length of time they are eaten.
