Recently, Handan City, Hebei Province issued the “Special Regulation Plan for Exceeding Standards for Fused Aluminum Foil in Handan City” and decided to carry out a special rectification of the fritters aluminum exceeding the city's limits within two months from now, in order to guarantee the safety of fritters food production and processing.
The author understands that this special rectification is divided into four phases, focusing on roadside shops, fast food restaurants, and breakfast supply points for yummy catering services, and implements 'three concentrations'. Among them, including food equipment and equipment, food Whether the containers and packaging materials, sanitary facilities, and process flow meet the standards, check whether excessive use of potassium aluminum sulfate and ammonium aluminum sulfate in the processing of fritters, etc., severely investigate and deal with the abuse of aluminum-containing food additives in accordance with the law, and fully protect the food safety of the people.
邯郸Turn on the frying of the aluminum fritters
It is well known that during the processing of traditional dough sticks, the addition of potassium aluminum sulfate (Alum) is mainly to increase the toughness of the dough stick and to reduce the breakage of broken bars. However, it is not added arbitrarily, and there is a demand for quantity. Since the addition of potassium aluminum sulphate will cause Aluminum residue in the fritters, long-term excessive intake of aluminum will lead to decreased ability to exercise and learning, and severe cases will affect children's intellectual development.
According to the relevant national standards, the 'aluminum residue' of fritters ((dry sample, in terms of Al, the same below) shall not exceed 100mg/kg. It is understood that the residue of aluminum in fritters sold in the first canteen of a college in Suzhou The detection value of 'Amount' was approximately 470mg/kg, and the residual value of 'Aluminum Residue' in the fritters sold by Nanjing School (Fifth Canteen) was approximately 1300mg/kg. Currently, relevant departments have strictly controlled and rectified it. Libao school cafeteria dining safety.
According to industry sources, fritters are one of the most common foods for people. The safety of production products can not be ignored. On the one hand, related departments actively promote the use of non-heading leavening agents, aluminum-free compound leavening agents, and fermentation-type aluminum-free compound puffs. New additive such as loosening agent is used to make 'non-stick fritters'. On the other hand, it strengthens supervision and uses related food testing equipment such as spectrum analyzers, mass spectrometers, etc. to timely detect aluminum content and ensure that excessive aluminum foods flow into the market.
At present, there are two methods for detecting aluminum, Spectrophotometry for the determination of aluminum in surface foods and Inductively Coupled Plasma Mass Spectrometry for Determination of Aluminum in Foods. However, the instruments used for inductively coupled plasma mass spectrometry are expensive. , The cost is very high, most of the general detection agencies and food companies still use spectrophotometry, and spectrophotometry in the actual operation is not obvious.
In order to further improve the detection effect, the original spectrophotometry was improved, which can effectively remove the interference of anions on the measurement. The operation is simple, fast, and accurate, the precision is good, the effect is remarkable, and the spectrophotometry is improved by adding an ethanol sensitizer. The sensitivity of aluminum is determined by photometry so that the aluminum content is closer to the true value.
Food safety has always attracted people’s attention and preventing the circulation of foods with excessive aluminum in the market is the key to ensuring the health of the people. The author believes that the “prohibition of aluminum orders” in the country is constantly advancing, and the relevant local authorities have vigorously controlled them. Next, the use of food testing equipment, strictly regulate the production and operation of food safety standards, ensure that consumers eat healthy, eat with confidence, and effectively protect the health of the general public and food safety.
