The invention provides polynary mixed instant rice and a
processing method of the polynary mixed instant rice, and belongs to the field of
food processing. According to the method,
rice flour is used as major ingredients,
wheat flour and coarse cereal flour are used as auxiliary ingredients, the major ingredients and the auxiliary ingredients are proportionally mixed, the water with the proportion quantity is added for uniform
tempering according to the
mass ratio of total quantity of major and auxiliary ingredients to water being 100: (10-30), then, the
extrusion granulation forming and the subsequent vacuum free
drying treatment are carried out, and the polynary mixed instant rice is obtained. The
rice flour is used as the major ingredients, the
wheat flour and the coarse cereal flour are used as the auxiliary ingredients, and a
recipe comprises the following ingredients in percentage by weight: 50 to 75 percent of
rice flour, 20 to 30 percent of
wheat flour and 5 to 20 percent of coarse cereal flour. The rice flour is adopted as the major ingredients, the wheat flour and the coarse cereal flour are adopted as the auxiliary ingredients, the polynary grain
carbohydrate and
dietary fiber nutrients can be obtained, in addition, the vacuum
freeze drying technology is adopted, the
nutrition ingredient loss of the instant rice is avoided, the rehydration performance of the product is obviously improved, and the rice with the corresponding
flavor and with rich elastic mouth feeling can be obtained according to the major and auxiliary ingredient mixing and the auxiliary ingredient combination.
