Food blender is a small machine, which can mix all kinds of fruits and vegetables to squeeze out fresh and delicious juice and vegetable juice. As shown in the figure below.
2, the working principle is different. High-speed mixer can instantly break the wall of fruits and vegetables, effectively extract plant biochemical substances, thus gaining the reputation of wall-breaking cooking machine, which is the first choice for modern family health care. The working principle of food mixer is that the blades at the bottom of the mixing cup rotate at high speed and break the food repeatedly under the action of water flow.
Extended data:
High-speed mixers do not necessarily make food more nutritious.
Yi Zhu, a professor at the College of Food Science and Nutritional Engineering of China Agricultural University, said that "breaking the wall" is actually harmful to grains.
According to her introduction, an article about porridge water in the American Journal of Clinical Nutrition explained the health status of people who eat different porridge ingredients: some data show that people who eat porridge water regularly have a 33% decrease in blood sugar, a 43% decrease in insulin and a 50% decrease in glucose-dependent insulinotropic peptide.
For example, wheat endosperm is like a wall around starch. Once ground into flour, the cell wall is damaged, and starch will be digested quickly, which will accelerate the increase of blood sugar. Maintaining the integrity of the natural structure of food ingredients can limit the absorption of food starch and reduce the ratio of starch to sugar. From this perspective, "breaking the wall" is of no help.
Only plants have cell walls, and the main body of cell walls is cellulose, which is not easily digested by human body. But the human body has oral cavity and gastrointestinal tract, which can play a similar role in "breaking the wall" to a certain extent. "The function of the wall-breaking cooking machine is actually to help the human body complete the process of' breaking the wall' from the teeth to the digestive system; You don't have to believe too much about the propaganda of this kind of machine. It is ok to improve the taste occasionally, and there is no need to rely on it every day. "
