The difference between starch and flour is divided into four aspects: raw material, color, composition, and use.
Starch generally refers to corn starch or potato starch, which is a powder obtained from corn or potatoes by milling and precipitation extraction, while flour generally refers to wheat flour, which is a powder obtained from wheat by milling and purification.
Starch is generally pure white in color, white and clean looking, while flour is generally dull white or white with yellow and slightly darker in color.
Starch is a high molecular carbohydrate, which is a polysaccharide polymerized from glucose powder, with a very low protein content, while flour is a high-protein food ingredient and a staple food often eaten by people in the north.
Starch is generally used more for thickening and pickling use, while flour is generally used to make buns, steamed bread, bread and other staple food pasta.
From the content of the two ingredients, flour is obviously more nutritious than starch, but because of the two in the daily consumption of the process of dosage itself is very different, so it is not good to compare and distinguish, if the two from the same portion of the comparison, then the flour will be better, for the following reasons:
Flour nutritional three elements are significantly higher. It is determined that every hundred grams of starch contains 0.2 grams of protein, 0.5 grams of fat, carbohydrates 86 grams, while every hundred grams of flour contains 9.2 grams of protein, 2.5 grams of fat, carbohydrates 68.4 grams, so so compared to the flour nutrients to be significantly higher.
Flour micronutrients are much richer.
It has been determined that starch contains sodium, magnesium, calcium, potassium, phosphorus, iron, copper, zinc *** eight minerals, no vitamins, and flour contains sodium, magnesium, phosphorus, potassium, calcium, iron, zinc, selenium *** eight minerals in addition to dietary fiber, ash, folic acid, vitamin B1, B2, B6, and vitamin E and other trace elements, so the starch nutrients can not be compared with flour.
