Abstract
The invention relates to high-dietary fiber five-cereal puffing powder and a preparation method, and belongs to the field of food processing. The five-cereal puffing powder comprises the following raw materials: coarse rice powder, wheat meal, oatmeal, millet meal, glutinous corn meal, soybean meal, wheat bran meal, calcium lactate, ferrous gluconate, zinc gluconate, vitamin B1, vitamin B2 and vitamin B6. A method for processing the five-cereal puffing powder comprises the following steps of: screening coarse cereals, grinding, milling, sieving with an 80-mesh sieve, mixing uniformly in a ratio, adjusting the moisture of materials, balancing the moisture, extruding and puffing by using double screws, drying, crushing, and sieving with a 100-mesh sieve, enhancing mineral elements and the vitamins. The high-dietary fiber five-cereal puffing powder has the characteristics that the puffing powder is prepared from natural grain coarse cereals, emulsifying agents and sweeteners are not added, the mineral elements and the vitamins are enhanced, the content of dietary fibers reaches the specified standard of national high-dietary fiber foods, and the puffing powder can be eaten only by being infused by boiling water, so that the high-dietary fiber five-cereal puffing powder is an ideal nutritional and convenient food which is suitable to be eaten by middle and old-aged people.
Description
technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a five-grain puffed powder with high dietary fiber and a preparation process thereof, in particular to a method for producing five-grain puffed miscellaneous grain powder by twin-screw extrusion. Background technique [0002] The nutritional value of miscellaneous grains is rich, and the proportion of nutrients is more in line with the intake needs of the human body. The unique oleic acid, linoleic acid, β-glucan, glutathione, riboflavin, lutein and other physiologically active ingredients form a Special therapeutic effect. my country has a large reserve of miscellaneous grain resources, has a relatively low cost advantage, and has the outstanding characteristics of integrating nutrition, safety, and health care. It is a natural, pollution-free, high-quality food base material. In recent years, with the continuous improvement of people's health awareness and ...
