Problems solved by technology

At present, there are many extraction methods of sweet potato protein. The authorized patent application number is 201210052356.0, the sweet potato protein thermal precipitation extraction process, and the master's thesis "Extraction of protein from sweet potato starch production waste liquid and research on antioxidant activity" all disclose a variety of sweet potato proteins. However, the extraction method has many steps, and alkali, acid, and organic solvents are added to the centrifugate in the centrifuge liquid alkali extraction, acid extraction, and organic solvent extraction, resulting in rapid protein flocculation and high impurity content, and the sweet potato protein extracted by these methods cannot be obtained. Direct consumption limits the use of sweet potato protein into food

Abstract

The present invention discloses a sweet potato protein paste and preparation method thereof, which belongs to the technical field of grain processing and mainly aims to solve the existing problems of low purity of sweet potato protein extract and low health-care ability of sweet potato protein paste. The sweet potato protein paste comprises the following raw materials in parts by mass: sweet potato leaves 40-60 parts, sweet potatoes 70-85 parts, glutinous rice powder 35-50 parts, astragalus membranaceus 4-12 parts, codonopsis pilosula 4-10 parts, ventriculi galli mucosa 3-9 parts, tangerine pith 3-9 parts, black beans 5-10 parts, peanuts 5-11 parts, Chinese yams 4-9 parts, Chinese wolfberry fruits 3-9 parts, red dates 3-8 parts, carrots 3-8 parts, and white sugar 4-11 parts. The sweet potato protein paste has rich nutritional ingredients, is suitable for consumptions of all ages, and has health-care effect in a long-term consumption.

Description

technical field [0001] The invention relates to the technical field of miscellaneous grain processing, in particular to a sweet potato protein paste and a preparation method thereof. Background technique [0002] Sweet potato protein has strong antioxidant activity, deoxyascorbate reductase activity and monodeoxyascorbate reductase activity, and can be used as an anti-aging substance. In addition, in addition to enhancing immunity, lowering blood fat, lowering blood sugar, reducing the incidence of hypertension and anti-cancer effects, sweet potato protein can also prevent diabetes, leukemia and other diseases. There are also a large number of mucus proteins contained in sweet potato protein It has a special protective effect on the human body. It can maintain the elasticity of the human cardiovascular wall, prevent atherosclerosis, reduce subcutaneous fat, prevent connective tissue atrophy in the liver and kidney, and lubricate the digestive tract, respiratory tract, joint ...
