Chestnut powder
Chestnut powder belongs to corn starch and is a carbohydrate formed by plant photosynthesis. It is a polysaccharide composed of a single type of sugar unit, which is naturally synthesized by plants. Starch is abundant in seeds, tubers and roots of plants. The varieties of starch include corn, rice, wheat, potato, sweet potato and cassava starch. In addition to the above main varieties, there are acorn, canna taro, kudzu root, Polygonum multiflorum starch and so on.
corn starch
Raw powder (white powder), also known as bean powder and water chestnut powder, is made from broad beans or water chestnut. Raw flour has a wide range of uses and can be used as a seasoning for cooking, bean jelly and pancake stalls. Mainly used for sizing and snagging when processing meat raw materials. Raw flour does not refer to any kind of starch. Raw flour is a term that often appears in mainland recipes and Hong Kong-style recipes, and it is mostly used for hooks. The raw flour used in Chinese mainland and Hongkong is corn flour, while the flour commonly used in Taiwan Province Province is Taibai. In China cooking, raw flour is often used as one of the cured meat materials to soften the meat quality, besides making the food taste smooth.
Food powder
Edible powder is baking soda, and its molecular formula is NaHCO3, which is an alkaline salt. Because its formula contains carbon.
Acid radicals, such as organic acids, inorganic acids or acid salts, will react after neutralization to produce carbon dioxide, which is the main driving force for the expansion and looseness of snack products. For example, when making peach cakes, the powder is decomposed by heat to produce carbon dioxide, which is heavier than air, so the gas expands horizontally on both sides. Make the peach crisp pour down and increase the volume. Another example is fried dough sticks, which use the reaction of edible powder and alum to produce a large amount of carbon dioxide gas to expand the volume. However, the edible powder should not be added excessively, because it is an acidic salt, which will increase the alkalinity and PH value, turn yellow inside and outside the product, destroy the tissue and have a bad shape. Therefore, it should be added appropriately when using it.
