The application discloses a quick preparation method of instant slow-digesting yellow waxy rice, and belongs to the technical field of
food processing.The method comprises the following steps: preparing high-pressure homogenized multi-
fruit juice,
asparagus setaceus water extract freeze-dried
powder and
liquid extract of
liquidambar formosanum leaves; preparing a composite yellow
dyeing solution; placing waxy rice in a mesh packaging bag, sealing the mesh packaging bag, and then placing the mesh packaging bag in a
dyeing and sealing bag; injecting the composite yellow
dyeing solution into the dyeing and sealing bag, and vacuumizing the dyeing and sealing bag; placing the dyeing and sealing bag at
room temperature for a certain period of time, and then performing ultrahigh-pressure treatment on the dyeing and sealing bag, and then placing the dyeing and sealing bag at
room temperature for a certain period of time; opening the dyeing and sealing bag, taking out the mesh packaging bag, and then draining the excess dyeing solution in the mesh packaging bag; placing the waxy rice in the mesh packaging bag in a high-temperature
steaming box, and then placing the high-temperature
steaming box in an outer packaging and sealing bag to steam for 40-50 min; taking out the outer packaging and sealing bag after
steaming, and immediately vacuumizing and packaging the outer packaging and sealing bag, and then refrigerating. The application shortens the preparation time of the waxy rice and prolongs the storage time of the waxy rice.
