Embodiment 1

[0031] Wash 20kg of whole broccoli, dry it, crush it with a pulverizer, squeeze it and filter it with gauze (300 mesh) to get 9.8L of squeezed juice and filter residue, put the squeezed juice into a pot and heat to 70°C, protein flocculation Float on the upper layer until the lower layer has no green color, and filter to obtain a filter cake (flocculation protein) and filtrate (9.0L). After the temperature of 9.0 L of filtrate was lowered to room temperature, it was concentrated using nanofiltration membrane (DK1812C, GE, USA) to obtain 2.8 L of concentrated solution. The flocculated protein and the concentrate were mixed and homogenized, and then spray-dried (BUCHI, small spray dryer B-290) to obtain 720g broccoli protein powder A, with a protein content of 41%.

Embodiment 2

[0033] Wash 20kg of whole broccoli, dry it, crush it with a grinder, squeeze it and filter it with gauze (300 mesh) to get 10.2L of squeezed juice, put the squeezed juice into a pot and heat it to 120°C, the protein flocculates and floats on the Filter the upper layer until the lower layer has no green color to obtain a filter cake (flocculin) and filtrate (9.2L). After the temperature of 9.2L filtrate was lowered to room temperature, it was concentrated using reverse osmosis membrane (SG1812C, GE, USA) to obtain 2.9L concentrate. The floc protein and the concentrate were mixed and homogenized, and then spray-dried (BUCHI, small spray dryer B-290) to obtain 718g broccoli protein powder B, with a protein content of 38%.

Embodiment 3

[0035] Wash 20kg of whole broccoli, dry it, crush it with a grinder, squeeze it and filter it with gauze (300 mesh) to get 9.5L of squeezed juice, put the squeezed juice into a pot and heat it to 70°C, the protein flocculates and floats on the The upper layer is filtered until the lower layer has no green color to obtain a filter cake (flocculation protein) and a filtrate. The floc protein was mixed with 2.8 L of purified water and homogenized, and then spray-dried (BUCHI, small spray dryer B-290) to obtain 682 g of broccoli protein powder C with a protein content of 52%.

Abstract

The invention relates to a brassica oleracea protein powder preparation method, which comprises: preparing a juice by adopting at least one organ selected from the stem, the leaf and the flower of brassica oleracea as raw material, carrying out heating flocculation on the juice, filtering to obtain solid protein and a filtrate, concentrating the filtrate through a membrane, mixing the concentrated filtrate and the solid protein, homogenizing, and carrying out spray drying to obtain the brassica oleracea protein powder. According to the present invention, the method has characteristics of simple process and strong operability; and the experiment results prove that the obtained brassica oleracea protein powder has effects of lowering of cholesterol in blood fat, and can be used in the fields of food, health products, medicine, and the like.

Description

technical field [0001] The invention relates to a preparation method of broccoli protein powder and the use of the prepared broccoli protein powder in reducing blood cholesterol. Background technique [0002] Broccoli (Brassica oleracea var. italia) is a variety of Brassica oleracea in the family Brassicaceae. It is native to Italy and is rich in bioactive substances and nutrients. It is known as the "crown of vegetables". The nutrients in broccoli are not only high in content, but also very comprehensive, mainly including protein, carbohydrates, fat, minerals, vitamin C and carotene, etc. Among them, the content of vitamin C is about 20% higher than that of cabbage flower, which is 2 times that of cabbage. -3 times, 5-6 times that of tomato; the content of carotene is more than 30 times that of cabbage flower; the content of folic acid is 2 times that of cabbage flower; the content of protein is 3 times that of cabbage flower and 4 times that of tomato. In addition, the mi...
