The invention provides high-
protein and low-breakage soybean fine dried noodles and a preparation method thereof, and belongs to the field of
food processing. The fine dried noodles comprise the following raw materials in parts by
mass: 48-50 parts of
soybean meal, 42-44 parts of high
gluten flour, 5-8 parts of
egg white powder, 1-2 parts of edible salt, 0.01-0.02 part of tea
polyphenol, 0.01-0.02 part of a
rosemary extract and 30-36 parts of water (based on the total formula
mass). Aiming at the problems of low
soybean meal addition,
low protein, high breaking rate, heavy beany
flavor and easy
grease oxidation of the traditional soybean fine dried noodles, industrial production of the high-
protein fine dried noodles with the
soybean meal content of 48-50% is realized through innovative
raw material proportioning and
process optimization, and meanwhile, excellent texture and eating quality of the product are ensured; the high-
protein staple food has the advantages of remarkably improving the
protein content and
nutrition balance, effectively reducing the breaking rate, inhibiting the beany
flavor, endowing natural bean fragrance, delaying
grease oxidation, prolonging the
shelf life and the like, the industrial production way of the high-protein
staple food is widened, and the requirements of consumers for healthy, convenient and delicious
staple food are met.
