The invention relates to the technical field of
food processing, and particularly discloses high-
nutrition pineapple noodles and a preparation method thereof.The high-
nutrition pineapple noodles comprise enzymolysis
wheat flour, high-
gluten wheat flour, modified pineapple residues, pineapple
soluble dietary fiber dry powder and blended
pineapple juice, the preparation method comprises the steps that S1, bromelain is used for conducting enzymolysis on the high-
gluten wheat flour to obtain the enzymolysis wheat flour, and the enzymolysis wheat flour is used for conducting enzymolysis on the pineapple
soluble dietary fiber dry powder; the method comprises the following steps: S1, squeezing fresh pineapples into juice, adding edible salt and dietary alkali, and blending, S3, synchronously extracting pineapple soluble dietary fibers from wet pineapple residues, and preparing modified pineapple residues, and S4, carrying out
dry mixing on all
solid raw materials, adding a pre-hydrated
dietary fiber glue solution and blended
pineapple juice, and carrying out dough kneading, dough standing, tabletting and slitting, and
drying so as to obtain a finished product. The activity of bromelain is inhibited through the edible salt and the dietary alkali, and
gluten protein is protected; the enzymolysis wheat flour provides
small molecule peptides, the
nutrition absorption efficiency is improved, the modified pineapple residues improve the
processing performance of the dough, and finally the nutrition enhancement and the
processing performance improvement of the product are achieved.
