Problems solved by technology

As a food, purple sweet potato can be peeled, dried and crushed, and then processed into whole powder. It can be used as the main ingredient and ingredient of various cakes, but purple sweet potato contains about 70% water. During the processing of the whole powder, not only water and vitamin B, A large loss of soluble components such as vitamin C also consumes a lot of energy
In addition, purple sweet potatoes can also be used as raw materials to make fried potato chips and frozen potato cakes. However, due to frying, the internal nutrients have been destroyed, thus far away from the theme function of purple sweet

Abstract

The invention discloses a preparation method of fresh purple sweet potato regenerated rice. The preparation method comprises the following steps of washing, pulping, tempering and granulating, wherein the tempering step comprises the following steps of: respectively grinding broken rice, chitosan and dry lotus seeds into powder, adding the powdered broken rice, chitosan, dry lotus seeds and Konjac powder into the pulp according to a ratio of pulp to broken rice to Konjac powder to chitosan to dry lotus seeds of 100 to (80 to 180) to (1 to 3) to (0.5 to 3) to (0.5 to 3), and performing the tempering, wherein the broken rice is broken long-shaped rice or polished round-grained rice, and the tempering temperature is 45 to 55 DEG C. The invention also discloses fresh purple sweet potato regenerated rice prepared by the method. The method and the prepared regenerated rice can effectively utilize water of fresh purple sweet potatoes and avoid the loss of nutrients, the gloss, water absorption performance, boiling resistance and viscosity of the regenerated rice are improved, and the prepared fresh purple sweet potato regenerated rice has good gloss, taste, flavor and chewiness, high nutritional value, good antibacterial performance and small adverse reaction.

Description

Technical field [0001] The invention belongs to the technical field of food processing, and specifically relates to a fresh purple potato regenerated rice and a preparation method thereof. Background technique [0002] Purple sweet potato (Ipomoea batatas (L.) Poir. Convolvulaceae Convolvulaceae) is also called black potato, purple sweet potato, purple sweet potato, etc. It is purple to deep purple. Purple potato is rich in nutrients and contains about 20% of protein, including 18 kinds of amino acids, which are easily digested and absorbed by the human body, including 8 vitamins such as vitamin C, vitamin B, and vitamin A, and more than 10 mineral elements such as phosphorus and iron. The most important thing is that they contain a large amount of peculiar effects and medicinal value. Higher anthocyanins. Anthocyanins are natural and powerful free radical scavengers, which can prevent and treat more than 100 diseases. They are known as the seventh most essential nutrient after ...
