The difference between flour and starch
Starch and flour are different in origin. Flour is wheat or other cereal grains after dehulling directly ground into powder, slightly yellowish, while starch is a polysaccharide substance obtained after separating proteins and other substances from flour, and is purer and whiter in color. It is insoluble in water and swells in hot water to become a viscous, translucent colloidal solution.
Starch is formed by the polymerization of glucose molecules and is the most common form of carbohydrate stored in cells. In addition to food, it is used industrially for making dextrin, maltose, glucose, alcohol, etc. It is also used for making printing paste, sizing textiles, gluing paper, and pressing pharmaceutical tablets. Flour is a kind of flour milled from wheat. According to the amount of protein content in flour, it can be divided into high gluten flour, medium gluten flour, low gluten flour and gluten-free flour.
From the content of the two components, flour will obviously be more nutritious than starch, but because the amount of the two in the process of daily consumption itself is very different, so it is not good to compare the distinction, if the two from the same amount of comparison of the three elements of flour nutrition are significantly higher. It was determined that every 100 grams of starch contains 0.2 grams of protein, 0.5 grams of fat, 86 grams of carbohydrates, while every 100 grams of flour contains 9.2 grams of protein, 2.5 grams of fat, 68.4 grams of carbohydrates, so the comparison of flour nutrition to significantly higher.
Flour trace elements to be much richer.
According to the determination, starch contains sodium, magnesium, calcium, potassium, phosphorus, iron, copper, zinc a total of eight minerals, no vitamins, while flour contains sodium, magnesium, phosphorus, potassium, calcium, iron, zinc, selenium a total of eight minerals, but also contains dietary fiber, ash, folic acid, vitamin B1, B2, B6 and vitamin E and other trace elements, so starch nutrition can not be compared with flour
