is often said that color, flavor and taste, shape are the key to attractive food, but taste the charm of the contribution of food can not be underestimated. Human beings naturally like to eat soft or crisp taste of the food, so soft, bread and cakes, crisp cookies华夫The Association does not release people I love. The reason why they can have a wonderful taste, in fact, lies one of the osteoporosis agent.
osteoporosis chemical agent, also known as hair swelling agents, some are not able, after fermentation can produce gas so that the dough becomes soft swelling material, the main for cakes, cookies, pasta, steamed bread, steamed stuffed bun,起酥bread, deep-fried dough sticks, puffed food processing.
in the traditional fermentation, the first to find a piece of "leaven" or buy "dry", which is mixed with dough. One of the yeast at the right temperature a large number of breeding up, put the dough in the micro-glucose, maltose into carbon dioxide, therefore noodle becomes swollen up. This process, will have aroma and B vitamins, but also improve the utilization of minerals, so the benefit of nutrition and health.
now commercially available "spontaneous powder" is very easy: as long as it is mixed with an appropriate amount of water, do not need to put yeast powder, can be steamed buns and steamed out. Since, one of the pre-osteoporosis agent placed at the heat after the chemical reaction will happen automatically emit carbon dioxide, so the food has a porous structure.
earliest hair swelling agent consisting mainly of carbonate, such as baking soda, soda ash, ammonium bicarbonate, ammonium carbonate and so on. However, the baking soda-type hair-expanding agent has a disadvantage: they aerogenes fast, easy for food have a big hollow, often arising from collapse after baking, the product of bad taste. In addition, they are too alkaline, may cause serious damage to noodle food vitamins, may also have macular food can affect the appearance. Ammonium bicarbonate and even produce ammonia, so that the product will have an unpleasant taste.
a result, people come up with many ways to help slow down the speed of gas, so that a more uniform fine pores. For example, partial replacement of light calcium carbonate with sodium bicarbonate, and then add acid salt is a good way. With alum, such as calcium carbonate acid salt mixture, when hot can slowly emit carbon dioxide, improve food quality. At present, the food industry used in detergents and hair-expanding osteoporosis agents usually are composite products, including alum, potassium hydrogen tartrate, dicalcium phosphate, gluconic acid lactone acid salts, etc., as well as calcium carbonate, sodium bicarbonate and other alkaline salts , and then add a small amount of starch. These substances with each other, let the dough before baking at the slow gas production, into the oven after the gas continues to bubble uniform, fine texture, natural for consumers satisfied. At present, the market's "powder" and household products, the main ingredient is sodium bicarbonate, alum and calcium carbonate, together with the starch of the filler, as well as flavor, sweeteners and so on.
osteoporosis agent Although the ingredients in the whole more secure, but there are also worrying place. Calcium and potassium are nutrients, trouble came mainly from the aluminum alum. Aluminum is not required by the human body, and the body when too much aluminum can lead to children's nervous system developmental disorders, and to promote Alzheimer's happened. With other more advanced formulations compared to aluminum-containing leavening agents are cheap, a lot of products because of the current over-the pursuit of loose texture, often add many leavening agent, or the use of aluminum-containing a large quantity of leavening agent, will give consumers with to potentially dangerous, especially in the brain which is in the development of children. Therefore, eating too much not to let children who are too "bulky" or "crisp" the noodle food and pastry products.
In addition, the sodium bicarbonate does not taste salty, but it is a source of sodium. So high blood pressure, heart people still try to eat less food containing leavening agents, to avoid excessive sodium intake.
