The invention discloses prepackaged fresh-keeping wet rice noodles with a normal-temperature
shelf life of 12 months and a preparation method of the prepackaged fresh-keeping wet rice noodles. 30-90% of early indica rice and 70-10% of
corn starch or
wheat starch are used as ingredients, so that the total content of
amylose in the mixed raw materials is greater than or equal to 21.5%; adding
lactic acid bacteria, and performing constant-temperature and constant-
humidity solid-state
Steaming the extruded rice vermicelli for more than two times; soaking the acidified vermicelli with
lactic acid drinking water;
softening and acidifying the vermicelli with hot water at 59-70 DEG C; and weighing, bagging, packaging, sterilizing, cooling and warehousing. The rice noodles are safe in
microorganism and physicochemical indexes, are not naturally broken, and are quick and convenient to brew / cook; the preparation method enhances the
toughness of the vermicelli, and the vermicelli is not easy to break;
steaming for multiple times to inhibit
retrogradation; through three high-temperature processes of squeezing,
steaming and high-temperature sterilization, the prepared rice noodles can
resist high temperature; the sterilization is thorough, and the
shelf life is longer.
