Abstract

The invention provides a method for preparing leisure foods on basis of a twin-screw extruder. The method for preparing leisure foods on basis of the twin-screw extruder comprises a crushing stage, afeeding stage, a mixing stage, a vacuum loading stage, an extruding-curing stage, a pre-drying stage and a second baking stage. On basis of the means of extruding-expanding, compression-roller-crushing and the like of the twin-screw extruder, brewing characteristics, taste and edible quality of whole grains are improved. By adopting the preparation method disclosed by the invention, in cooperationwith corresponding process and formula adjustments, the brewing characteristics, palatability, digestion rate and absorption rate of whole grains are improved. The production technology disclosed bythe invention is suitable for continuous industrial production of nutritious whole-grain leisure foods; moreover, the production technology is high in automation degree, energy-saving and environmentally friendly. In addition, according to material process, drying is performed when moisture content is relatively low, so that energy consumption is reduced with high energy utilization rate achieved;and thus, the sustainable development strategy of human being is met (namely, the energy consumption is only 25-40% compared with traditional methods in terms of preparing leisure foods of the same types).

Description

technical field [0001] The invention relates to the field of food technology, in particular to a method for preparing snack food based on a twin-screw extruder. Background technique [0002] Whole grains are recognized as pollution-free green food, which contain natural protein fat, carbohydrates, vitamins, minerals and dietary fiber and other nutrients, which meet the reasonable ratio of human intake and have high utilization value. It contains a variety of unsaturated fatty acids, such as oleic acid, linoleic acid, linolenic acid, phospholipids, oligosaccharides, polysaccharides and flavonoids, etc., which have the functions of preventing and resisting diseases, enhancing immunity and delaying aging. effect. Although miscellaneous grains have many advantages in terms of nutrition, due to the different tastes of people in various places, it has caused certain obstacles for people to eat miscellaneous grains for a long time. How to really eat coarse grains without changi...
