Technical Field

The embodiment of the invention relates to the technical field of food processing, and particularly relates to a preparation method of a fried bread stick green body.

Background

The deep-fried dough sticks are ancient Chinese wheaten food, strip-shaped hollow fried food, are crisp and tough in taste, and are one of the traditional breakfast in China. The making process of the fried bread stick is that firstly, soda, salt, alum and flour are added with water and kneaded, the dough is fermented to a certain degree and then cut into strips with the thickness of 1 cm and the length of 10 cm, every two strips are overlapped up and down, the narrow wood strips are pressed in the middle, after the two strips are rotated, the strips are stretched and put into a hot oil pan for frying, and the strips are expanded into the fried bread stick which is loose, crisp, yellow and fragrant.

Along with the acceleration of the pace of life of people, quick-frozen food is more and more popular with consumers because of the advantages of simple cooking and convenient eating. In order to meet the requirements of consumers, quick-frozen deep-fried dough sticks are slowly appearing on the market. Although the quick-frozen fried bread sticks in the existing market are semi-finished quick-frozen fried bread sticks, and can be eaten after being directly re-fried during eating, the operation is simpler, and the eating is more convenient, but the taste of the fried bread sticks is relatively poorer, and the oil content can be increased after the re-frying, so that the fried bread sticks are unhealthy. In addition, the existing quick-frozen fried bread sticks become hard after being fried again and cooled, and the taste of eating is influenced. In addition, the semi-finished quick-frozen deep-fried dough sticks are large in size and inconvenient to store and transport.

The technical current situation of the prior green deep-fried dough sticks is as follows: in the aspect of the formula, the gas is generated mainly by eating the leavening agent or baking powder to make the fried bread sticks expand and rise. The method has the following defects: 1. a large amount of chemical food additives are used, so that the burden is caused to the human body and the health of the human body is damaged; 2. the product lacks the fragrance of flour, and the bitter and astringent feeling caused by the leavening agent and the baking powder can be produced when the product is put back into the mouth; 3. the shell of the fried product is hard and not crisp. After cooling, the product is more obvious, difficult to chew and poor in quality experience. In the aspect of the process, some technologies adopt twice dough kneading, namely twice dough kneading is needed, the operation is complicated, the industrial production is not facilitated, and the labor is consumed.
