Belonging to the field of food
deep processing, the invention relates to a preparation method and process of five-
colored steamed rice. The basic process of the five-
colored instant steamed rice consists of: subjecting rice to dip
dyeing,
steaming, rice blending, hot filling, and vacuum packaging, thus obtaining a finished product. The method is characterized in that: polished round-grained rice, glutinous rice or germinated
brown rice is adopted as the
raw material, natural pigments derived from different plants are employed to dye the rice into different colors, the juice of caulis spatholobi is used to dye the rice red, the juice of
Peristrophe roxburghiana is used to dye the rice purple, the juice of
Vaccinium bracteatum Thunb leaves is used to dye the rice black, the juice of
curcuma longa is used to dye the rice yellow, and a part of undyed rice (white) is retained to constitute five colors. In the invention, a vacuuming penetration technology is employed, the rice
dyeing rate is accelerated, and the
process time is shortened. With a high degree of industrialization, the method produces the five-
colored steamed rice with the characteristics of aromatic
flavor, rich
nutrition, and strong health care. As the plants for
dyeing all contain abundant functional components, the
nutrition and health care components of the steamed rice are increased. The five-colored steamed rice can serve as both a
staple food and a leisure
health food.
