Abstract
The invention discloses a sweet potato nutrition silk noodle and a preparation method thereof. The preparation method comprises the following steps of (1) material selection; (2) cleaning; (3) peeling; (4) pulping: peeled sweet potatoes are subjected to extrusion crushing; the extrusion crushing speed of the peeled sweet potatoes is 10 to 100kg/min; color protection liquid is added at a speed of 20 to 200kg/min in the extrusion crushing process; the mixture passes through a 60-100 mesh sieve to obtain sweet potato raw pulp; (5) primary separation; (6) refined filtration; (7) secondary separation; (8) sweet potato nutrition silk noodle preparation. According to the sweet potato nutrition silk noodle and the preparation method of the sweet potato nutrition silk noodle disclosed by the invention, the sweet potato nutrition silk noodle is prepared by using non-transgenic sweet potatoes as raw materials through material selection, cleaning, peeling, pulping, primary separation, refined filtration and secondary separation. Compared with the prior art, the pulping process has the advantages that the color protection liquid is used for enzymolysis and color protection fresh keeping; the fast, efficient and foreign-matter-free addition is realized; the biological active ingredients can be effectively protected. The sweet potato nutrition silk noodle is favorably absorbed by the human body; the nutrition and health care values are high.
