Is stick bulking agent harmful to human body

Introduction: every morning when I go to work, I always see a long line in front of several fried dough sticks stalls The boss is very busy Is the swelling agent in the dough stick harmful to human body? As a kind of traditional food with a long history, fried dough sticks are deeply loved by the people Even many times, "fried dough sticks + soymilk" once became the synonym of common people's breakfast Is the leavening agent in the dough stick harmful to human body? 1 Frying technology High temperature frying is the most important link in the production of oil sticks Only by frying can you get the soft or crisp golden oil sticks For the sake of cost, street vendors often use a pot of oil repeatedly and heat it repeatedly, even if it uses qualified oil After heating and using it repeatedly, not only the color of oil becomes darker and thicker, but also the fatty acids and vitamins beneficial to human body in the oil At the same time, the high temperature also makes the oil decompose into the carcinogens, acrylamide and polycyclic aromatic hydrocarbons, which are harmful to people's health According to the author's observation, the general traders will not change all the oil after it becomes black and thick, but will filter out the dregs, pour out some frying oil and add some new oil, which leads to the repeated use of old oil in the pot 2、 High fat intake: as a fried food, the high calorie of the oil bar can not be ignored The oil content of some oil sticks is as high as 30% The oil content of a 50g oil stick is generally 10-15g, while the daily oil intake recommended by the dietary guidelines in China is 25-30g The excessive intake of high-energy food also increases the incidence of obesity, hypertension, hyperlipidemia, cardiovascular and cerebrovascular diseases, bringing people health risks The Ministry of health's upcoming "personal physical activity guidance program" gives a reference to the energy generated by each food and how the activities can be consumed For example, to eat a 100g oil stick, you need to walk at least 13568 steps at a moderate speed to consume 423.8 kcal of energy generated by the oil stick 3、 The use of bulking agent is inseparable from the production of oil stick When fried, the traditional way is to add alum (potassium aluminum sulfate) to the wheat flour to make the dough stick swell in the high-temperature oil pot Alum contains aluminum, because there is no uniform standard, street vendors abuse, excessive use, resulting in a large number of aluminum elements in the oil sticks in excess of the standard What is more worrying is that the alum dosage used according to the national aluminum limit standard can't make the oil stick swell at all For example, the aluminum content of a 50g oil stick is about 10mg If you eat two oil sticks every day, your body will take up to 600mg of aluminum in a month Aluminum is a low toxic metal element, which will not lead to acute poisoning Only 10% to 15% of aluminum is discharged from the body after ingestion, most of which will be accumulated in the body, interfere with human metabolism, affect various biochemical reactions in the body, and cause long-term and slow harm to health Because of the brain's affinity for aluminum, aluminum is often called "intelligence killer" The content of aluminum in the brain of Alzheimer's patients is generally 4-30 times higher than that of normal people, which is one of the important reasons for Alzheimer's disease Long term excessive aluminum intake will not only damage the brain, but also cause anemia, osteoporosis, organ damage and so on, especially for the elderly, children, pregnant women and so on The main feature of the aluminum free dough stick bulking agent is that it does not contain alum But for many vendors, without alum, not only the taste of the dough stick is not as crisp and delicious as the fried alum, but also the cost will increase Originally, it is a small business without supervision, and consumers do not pay attention to the use of any kind of bulking agent, which also results in the fact that basically all the dough sticks we see are purchased The important reason of using alum as bulking agent The above is the introduction of the relevant content of the leavening agent, so can the food leavening agent eat for a long time ? you need to remind your friends that although the leavening agent is helpful for the taste effect of food in baking, it will also cause harm to your body if you eat it for a long time This is what you need to pay attention to, not only focusing on food, but also paying more attention to health Now the country has a food safety detector, which can accurately check whether the food is safe, edible, and will not cause physical harm If you want to know more about food safety, please go to Baibai safety net Editor in charge: he xianrob
