Description

technical field [0001] The invention relates to the field of food processing, in particular to a gluten-free fried dough stick made from sweet potato crude dietary fiber and a preparation method thereof. Background technique [0002] Deep-fried dough sticks are a kind of convenient food with high quality and low price, which are usually eaten for breakfast and occupy a place in the catering industry. Traditional fried dough sticks are made by first mixing alum, alkali, salt and water into wheat flour to make dough, and then deep-fried at high temperature. Among them, alum is a compound salt with aluminum sulfate as the main component, which contains a large amount of aluminum. Experiments have proved that excessive intake of aluminum is harmful to the human body, and eating it often is harmful to health. In addition, traditional fried dough sticks are made of wheat flour. In the processing of wheat flour, many nutrients are lost due to excessive pursuit of processing precis...
