Abstract

The present invention discloses a complex extraction method for rice protein. The method includes a total of 7 production processes: pulverizing rice, grinding the rice, extracting the rice with a dilute alkali solution, centrifuging the extract, sterilizing the centrifuged extract, precipitating the sterilized extract and drying the precipitated extract. The production processes are simple in technology and easy to operate; extracted rice protein products are pure and natural, and are high in quality, rich in nutrition and powerful in health care function. The method is reasonable in technology, small in labor intensity, high in production efficiency, and reliable in quality.

Description

technical field [0001] The invention relates to an extraction method, in particular to a composite extraction method of rice protein. Background technique [0002] Protein is the main source of nitrogen for the human body. It can not only provide part of the energy consumed, but also be used to synthesize new tissues. Protein accounts for about 17% of body weight in adults, and 3% of protein participates in metabolic renewal every day. When there is insufficient protein in the body, people's basic life activities will be affected, which can lead to growth retardation, underweight, and mental retardation in children and adolescents; fatigue, weight loss, anemia, decreased plasma albumin, and even edema in adults. However, the traditional protein extraction method is complicated in process, low in efficiency, labor-intensive, and difficult to guarantee the quality. In view of the above-mentioned defects, it is necessary to design a compound extraction method of rice protein....
