Technique for preparing glucoraphanin-riched broccoli concentrated powder

Abstract

The invention provides a technique for preparing glucoraphanin-riched broccoli concentrated powder. The technique comprises: selecting and pruning raw material (1), cleaning (2), chopping (3), extracting (4), filtrating (5), beating (6), extracting (7), filtrating (8), concentrating and recovering alcohol (9), drying (10), cooling (11) and then obtaining the product (12); toxic solvents are not contained in the extracting process, making the health-care products safely and reliably; the extracting equipment is simple, do not need improvement on the prior technique, and has advantages of low investment and easy implement.

Description

Technical field:

[0001] The invention provides a preparation process of concentrated broccoli powder, in particular relates to a preparation process of concentrated broccoli powder rich in Glucoraphanin glucosinolate. Background technique:

[0002] Glucosinolates (GLS for short) is a sulfur-containing secondary metabolite, which widely exists in 15 dicotyledonous plants. Among them, the glucosinolate content of Cruciferous plants is very rich, and the anticancer activity is also particularly large, and has received extensive attention. So far, more than 120 glucosinolates have been discovered. Although glucosinolates are present in all tissues of the Brassica genus, and some plant species contain 15 different glucosinolates, the vast majority of plants contain only a few types of glucosinolates, and the content is not too high . Although broccoli is not the highest in total glucosinolates, it has a high content of active glucosinolates. The glucosinolates contained are m...
