The invention discloses an extruded puffed
fiber food and a preparation method thereof and belongs to the technical field of
food processing. The extruded puffed
fiber food comprises the following components in parts by weight: 10-50 parts of
wheat flour, 15-50 parts of
fiber flour, 0.2-5 parts of salt, 0.2-10 parts of
calcium carbonates, 0.1-30 parts of
conjugated linoleic acid, 0.1-5 parts of konjac fine flour, 0-80 parts of buckwheat
powder, 0-80 parts of oat
meal, 0-80 parts of tartary buckwheat flour, 0-80 parts of dehydrated potato
powder, 0-80 parts of
corn starch, 0-80 parts of rice
meal, and 0-10 parts of seasonings. The food disclosed by the invention is prepared from fiber flour through the following steps: mixing the fiber flour with other components, humidifying the obtained mixture, then carrying out
extrusion puffing on the humidified mixture,
seasoning the obtained product, and baking the seasoned product. The food disclosed by the invention can be used for solving theproblem that a food with a high fiber content is rough in taste and difficult to digest after being eaten; and simultaneously because an appropriate amount of the
conjugated linoleic acid is added, the
conjugated linoleic acid and the fiber in the invention can enable the food to achieve an effect of
weight loss and
fat removal and an effect of improving the
extrusion puffing characteristics and taste of the fiber food.
