supermarket counters the puffed food always attracts a child's eyes, and let young people away happy. When watching TV, surfing the Internet when Boring after a meal, the meal when you are hungry ... ... tasty puffed food always people's first choice for food.
puffed foods attractive because, on the one hand are a variety of seasoning because of its characteristics, but more importantly it is because it has crisp cool taste charming. Almost all brands have their products advertised at a more crisp, their own taste Gengshuang. However, consumers have not thought of, where are these wonderful taste come from?
expandable crisp taste of the origins
Generally speaking, a food to become fluffy, and only four ways: one is the result of yeast fermentation produces carbon dioxide gas, so that the texture of porous foods, steamed bread is in this category; the other is sent with protein, resulting in a bubble, after high-temperature fixed, the cake is that this category. The third is the expansion of chemical hair is salt and acid salt alkaline reaction, resulting in many carbon dioxide, thereby allowing Products osteoporosis. Cookies, deep-fried dough sticks fall into this category. The fourth is a high-handed puffing, put the product high temperature and high pressure treatment, and then a sudden decompression, the product of internal gas expansion, resulting in loose porous structure, popcorn fall into this category.
first of all to determine that the puffed food did not undergo fermentation, it has not been sent, and its bulky texture, mainly from chemical hair swelling and puffing process. Extrusion Process Although osteoporosis can let the initial Product, but only together with the help of chemical hair-expandable, so that consumers can achieve even more intoxicated with the sparse brittle texture.
then, chemical expansion agents in hair has what? According to relevant information, our country for food processing, hair swelling agents, baking powder and other chemicals which contain mostly sodium bicarbonate and alum, including potassium alum and ammonium alum, etc., are commonly used in deep-fried dough sticks, bread and cookies and other food products, including the Expanded Food .
puffed food will bring about many of aluminum?
hair in a variety of swelling agents, the products contain alum usually "cheap" hair-expanding effect, stomatal fine, Price is also relatively low. The experimental results show that the higher the dosage of alum, expanding the better hair. However, alum contains aluminum elements, add alum will bring aluminum residue problem. Although non-aluminum leavening agent has already successfully developed, but because higher costs are often neglected by businesses.
national standards in accordance with the provisions of extruded aluminum in food residues should be less than or equal to 100 mg / kg, equivalent to one ten thousandth of the residues. However, because the pursuit of "more crisp" taste, a lot of products are added to high aluminum content in hair-expanding agent, give the children brought aluminum pollution problems.
According to the China Agricultural University, Institute of food in 2005 a determination有三成Aluminum extruded food residues exceeded. After various investigations, to exclude food machinery and food packaging possible pollution, conclusive evidence for the expansion of aluminum-containing hair caused by excessive doses.
calculated in accordance with the standard twice, each eating 100 grams of puffed food, it will bring about 30 mg of aluminum. For a 30 kg body weight of children, this is their best day of the highest volume of intake. Since other foods will also contain traces of aluminum, aluminum intake of total children will certainly be exceeded.
knowledge link: aluminum security
1989, the World Health Organization (WHO) formal announcement, aluminum is a kind of food contaminants, the daily intake required to control the quantity, Acceptable Daily Intake for 1mg/kg. In other words, if an adult weight of 60kg, then 60mg every day up to permit intake of aluminum, if children are lighter weight, then the intake will be less every day. It has been reported in the literature at home and abroad, probably caused by excessive aluminum intake nervous system disease, manifested as memory impairment, tremor and physical co-ordination disorders, and may even increase the risk of senile dementia. Of children, the aluminum may affect mental development, interference with thinking and memory function. Excessive accumulation of aluminum in the body organs can also lead to the corresponding pathological damage, doubt it can promote the occurrence of cardiovascular disease, and affect bone health.
except puffed food, aluminum is also hidden in Where
except puffed food outside, it is necessary to add aluminum-containing additives also a lot of food. Cookies, cakes, all kinds of pasta, deep-fried dough sticks, egg rolls, crisp points, fans, such as food, are likely to happen over the issue of aluminum. According to media published test data, more than 70% of deep-fried dough sticks, cake, pasta and crisp crispbread, such as aluminum residues exceeded, and some even exceeded by as much as ten times! Such a deep-fried dough sticks only eat one, it will pose a threat to human health.
If a person every day to eat 50 grams of puffed food, coupled with a deep-fried dough sticks, plus a small amount of cookies, or pasta and so on, every day will eat more than one hundred milligrams of aluminum element, on the human health threat, and it can not be neglected.
consumers must want to strengthen the self-care awareness, not to blindly pursue "more loose, more crisp" taste to enjoy, do not eat or eat less deep-fried dough sticks, puffed food, cookies and other foods, more At the same time not to eat the food of these species. Basically, these foods are very low nutritional value of products, eat less or eat them, nutritional balance of meals were very helpful.
Important note: day-to-day at home cooking in aluminum to reduce pollution
- no less with bulk agents, baking powder, spontaneous powder Product
- no need to soak hair alum give food or food security Green
- not铝锅to have salty or有酸味cooking food
- new several铝锅要煮times re-use, but often not to scrub with steel balls to wall.
In addition, the puffed food's "crisp" feeling often comes from hydrogenated vegetable oil. Today, puffed food, no longer like the past, like low-fat popcorn, but add 15% -30% of the oils and fats, and are usually rich in saturated fatty acids content of hydrogenated vegetable oil ingredients. So, they not only high-calorie, high fat, but also harmful to the heart of a child's nervous system also have an impact. See details of my other relevant log.
