Soda biscuits are made by adding yeast to a part of wheat flour, then blending into dough, adding the remaining wheat flour after a long period of fermentation, and molding after a short period of fermentation.
Advantages: less sugar and less oil.
note:
1) Eating soda cookies increases sodium intake, which can increase blood pressure and aggravate edema.
2) Eating soda cookies will increase the intake of fat, make it easier to gain weight, and increase the risk of chronic diseases such as diabetes.
Second, whole wheat, digestive biscuits.
Whole wheat and digestive biscuits are biscuits made by grinding wheat without bran into flour, which are darker in color and thicker in taste than refined flour without bran. For example, we usually eat rich and strong flour, but because a large number of vitamins, minerals and cellulose are retained in the bran, the nutritional value is higher.
Advantages: the cellulose content is relatively high.
note:
Because the taste of cellulose is very poor, in order to improve the taste of cellulose and make it crisp, a lot of oil may be added, so the oil content is relatively high, which is easy to raise blood lipids and is not good for preventing heart disease.
Third, sandwich biscuits.
The key to making sandwich biscuits with different flavors is to add different auxiliary materials, such as oil, sugar, milk, eggs and other flavors.
The fat content of ordinary biscuits is not high, but with sandwiches, the fat and sugar content increase obviously, becoming a high-calorie food. The calories of 100g steamed bread are about 226 kilocalories (945 kilojoules), while the calories of 100g biscuits are more than 1 times higher than steamed bread! When making biscuits, fat and sugar are added to flour, which is very high in calories, especially biscuits and sweet and crisp sandwich biscuits.
Advantages: sweet taste and rich taste.
Note: Cookies are a good choice for people who need to supplement calories in a short time, such as middle and high school students taking meals during recess and heavy manual workers supplementing calories. If you need to control your weight, as well as patients with hyperlipidemia and hyperglycemia, try to eat less or no biscuits.
Fourth, nutritional fortified biscuits.
There are also some nutritious biscuits on the market. The most common varieties are fortified minerals and vitamins, such as calcium, iron, zinc, vitamin A, vitamin D and so on. Some of them are added with wheat bran, which belongs to increasing dietary fiber.
Advantages: Some cookies can be added with a certain amount of calcium and iron, which is more nutritious than some cookies.
note:
It is beneficial for children who are picky eaters to eat some biscuits fortified with calcium, iron and zinc. However, as an ordinary person, if you can achieve a balanced diet without obvious nutritional deficiency, or you are already taking nutritional supplements, you should be alert to two situations when choosing fortified nutritional biscuits: first, nutrition has not been absorbed and wasted; Second, excessive absorption of nutrients has a negative impact on the human body.
Four measures to identify the quality of biscuits
First, look at the surface: a good biscuit has complete shape, clear pattern, fine texture, basically uniform thickness, no shrinkage and deformation, fine and uniform pores, easy to break by hand and no impurities. Inferior biscuits are blistered, rough in texture, badly damaged and stained. Some cookies even contain impurities and are moldy.
Second, smell identification: good biscuits should have the unique flavor of the product, pure sweetness, crunchy and turpentine, no odor, and no sticky teeth; Sub-quality biscuits have a firm taste and are not brittle; Inferior biscuits have a rancid oily smell.
Third, the sensory identification of tough biscuits: the surface, bottom and edge of good biscuits are uniform golden yellow or grass yellow, and there is a bright gelatinization layer on the surface; The color of inferior biscuits is uneven, the surface is not bright, there are flour or flowers, and the color is slightly different.
Fourth, when purchasing biscuit products, we should pay attention to the production date. All kinds of labels on biscuit packaging should be standardized and complete, and the label must have QS mark.
