This is also very possible because washing powder contains alum . "Flour and laundry detergent mixed, the fritters are fluffy and golden in color." A source told a reporter that the doughnuts that were put into the washing powder swelled up better. "This is because washing powder can expand, which makes the flour expand better. As a result, the doughnuts look crispy. It is for this reason that the doughnuts are relatively pretty."
"This doughnut gives you a little bit of flavor because it's crunchy, so it tastes good." Sources close to the situation say suppliers are "very picky" about the laundry detergent they use. Most laundry detergents on the market nowadays are scented, and when deep-frying the doughnuts, unscented laundry detergent must be used, otherwise the doughnuts will have the scent of laundry detergent on them It is understood that it is precisely because the laundry detergent used is the most primitive laundry detergent that the cost of the raw material is not high.
Will alum be added to the doughnuts? Many people say, "I've heard that without alum, doughnuts can't be made because they need to expand." In response, some experts say that small amounts of alum in doughnuts have little effect on health. "Although many people also favor the traditional alum doughnuts, once two kinds of doughnuts are put in front of them for them to choose from, they are still willing to spend more money and eat doughnuts without alum.
The bag of the doughnut flavoring clearly states Food Additives and is labeled for use:Doughnuts, sesame flowers, pancakes, paste deep-fried products and so on. Ingredients:Sodium bicarbonate, potassium hydrogen tartrate, flour improver, edible calcium and so on. Alum and alkali used to be used to fry doughnuts. Now with the addition of this doughnut extract it is very cheap." The chef explains that alum is not used because it is rarely sold separately." Usually, one packet of 50 kilograms. When does it run out? It is more convenient to use this, so most doughnut stalls now use this cream."
