Problems solved by technology

The glutinous rice made by this method not only takes a long time, but also greatly dilutes the original fragrance of maple leaves. The color of black glutinous rice is easy to appear gray, which is far from the effect of jet black, and it is not resistant to storage, and it is easy to change after a period of time. hard, darkened
[0005] Chinese patent (application number 201510357468.0) boils maple leaves in water, soaks them for 2-3 hours according to the weight ratio of glutinous rice and water 1:2, filters and drains the surface water of glutinous rice, and steams for 30-50 minutes. The black color made by this method Glutinous rice is easy to turn gray or brown, and it cannot achieve the effect of jet black, and the taste is hard, so it is not resistant to storage
The black glutinous rice produced by this method is not black enough in color and tends to be taupe, and it is not resistant to storage. It is prone to discoloration and texture changes during storage, resulting in poor taste
[0008] Although maple leaf is rich in mineral elements, the minerals in it cannot be effectively dissolved through simple water extraction or ultrasonic water extraction, and the elements that can finally penetrate into glutinous rice are even less

Abstract

The invention discloses a method for preparing refrigerated instant black glutinous rice, and belongs to the technical field of food processing. The method comprises the following steps: soaking glutinous rice with black dye prepared from maple leaves, adding a calcium preparation and a iron preparation at the same time, then performing filtering, performing draining, sequentially adding amylase,apple polyphenol, polylysine, xanthan gum and sesame oil, and performing stirring, steaming and packaging. As the calcium preparation, the iron preparation, the amylase, the apple polyphenol, the polylysine, the xanthan gum and the sesame oil are added in a preparation process, the glutinous rice has a blacker and more uniform color and softer and elastic texture, and is storable. The glutinous rice can be stored for 6 months under a refrigeration condition, is safe and sanitary and is convenient to eat.

Description
