The digestion of starch in the body is mainly carried out in the mouth, stomach and small intestine. The chewing of teeth in the mouth and the stirring of the tongue help to crush starch blocks, promote the mixing of starch and saliva, and decompose starch into dextrin and maltose. The undigested starch, dextrin and maltose in the oral cavity will be further converted into glucose under the action of gastric acid, pancreatic amylase and disaccharidase after entering the stomach. In the intestinal tract, disaccharidase can decompose maltose and convert it into glucose, which is finally absorbed in the form of glucose.
What is starch:
1. Starch is polymerized from glucose molecules, usually extracted from plants, and is one of the most basic ways for human body to obtain glucose. Starch is also called gorgon starch, which can be used for sizing, thickening, and pasting. It can be used for making cold skin, baking desserts, etc. There are many kinds of starch, and potato starch is the most common.
2. Starch is polymerized from glucose molecules, which is the most common storage form of carbohydrates in cells. This is also one of the most basic ways for the human body to obtain glucose. Starch is also a nutrient stored by plants, and the content of starch in various plants is relatively high.
3. Starch, also known as gorgon starch, is mainly used for sizing, thickening and pasting. It can be used for making cold crust and baking desserts. There are many varieties of starch, such as corn starch, mung bean starch, sweet potato starch and wheat starch.
4. Mung bean starch is one of the best starches. It has less water absorption and is very viscous. It is usually used for making soup. Potato starch is the most commonly used starch in the family. It is usually used for cooking. It has poor absorption and cannot be used for making soup.
