specific Embodiment approach 1

[0023]Specific embodiment one: this specific embodiment adopts the following technical scheme: it is to be trimmed by raw material selection 1, cleaning 2, chopping 3, extracting 4, filtering 5, beating 6, extracting 7, filtering 8, concentrating, reclaiming alcohol 9, Drying 10, cooling 11 and product 12 are composed of several processes; raw material selection and pruning 1 is 1000 kg of broccoli, and the cauliflower with rotten fruit and serious pest damage is removed, and the rotten and silt parts are removed with a knife. When selecting and pruning, handle with care and place them separately. Each basket (or basket) should not be filled too full to prevent crushing or crushing; cleaning 2 is that the cleaning speed varies depending on the variety, fruit size, and cauliflower size. Sediment is the degree. Cleaning water needs to be kept clean, use running water to wash raw materials, and thoroughly wash at the end to ensure cleanliness; chopping 3 shredders cut into a thic...

specific Embodiment approach 2

[0025] Specific embodiment two: it can also be composed of seed removal 1, grinding 2, extraction 3, filtration 4, slag re-extraction 5, concentration, recovery of alcohol 6, drying 7 and product 8; the seed removal 1 is 120 kg of seeds, sieved, to remove impurities; milling 2 is crushed to more than 80 mesh with a mill; extraction 3 is to enter 5 kg each time into a 20L extraction tank, add 95% ethanol according to the raw material ratio of 1:2, seal, and water bath Heat up to 70°C and keep warm for 20 minutes; filter 4 is filter with 4 layers of gauze. The liquid was collected; the slag was re-extracted 5 by adding 95% ethanol at a ratio of 1:1 of the raw material, sealing, and raising the temperature of the water bath to 70° C. for 20 minutes. The liquid was collected by filtration. Slag extraction was repeated 4 times; Concentration and recovery of alcohol 6 is to combine multiple extractions, concentrate and recover alcohol in a 20L rotary evaporator; Drying 7 is to take...

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...
