Embodiment 1
[0010] Rapeseed meal was used as raw material, water was added, the ratio of solid to liquid was adjusted to 1:8, the extraction temperature was 100°C, the extraction time was 30 minutes, and the extraction rate was 90%. The extract was adsorbed by macroporous adsorption resin SD600, the adsorption temperature was 35°C, the adsorption time was 3 hours, the adsorption capacity reached 114umol / g, the eluent was 50% ethanol, the elution time was 1 hour, and the elution rate was 60 %, the eluate was distilled at 2°C at a low temperature and vacuum-dried to obtain a glucosinolate product with a purity of 97%.
Embodiment 2
[0012] Rapeseed meal was used as raw material, water was added, the ratio of solid to liquid was adjusted to 1:10, the extraction temperature was 100°C, the extraction time was 30 minutes, and the extraction rate was 92%. The extract was adsorbed by macroporous adsorption resin SD600, the adsorption temperature was 35°C, the adsorption time was 3 hours, the adsorption capacity reached 110umol / g, the eluent was 60% ethanol, the elution time was 1 hour, and the elution rate was 66 %, the eluate was distilled at 4°C at a low temperature and vacuum-dried to obtain a glucosinolate product with a purity of 95%.
Embodiment 3
[0014] Rapeseed meal was used as raw material, water was added, the ratio of solid to liquid was adjusted to 1:9, the extraction temperature was 95°C, the extraction time was 45 minutes, and the extraction rate was 92%.

Abstract
The invention discloses an industrialized extracting and purifying method for glucosinolate. The method comprises the steps: adding water into rapeseed dregs which serve as a raw material, adjusting the material / liquid ratio to be (1: 8) to (1: 10), and extracting for 30-45 minutes at the temperature of 95-100 DEG C; adsorbing an extract by adopting macroporous adsorption resin SD600 for 3-4 hours at the temperature of 35-40 DEG C, eluting with 50-60% ethanol, which serves as an eluant, for 1-2 hours, and enabling an eluate to be subjected to low-temperature distillation and vacuum drying, thereby obtaining a glucosinolate product, wherein the purity of the product reaches over 95%.
Description
technical field [0001] The invention relates to a method for extracting and purifying glucosinolate, which belongs to the field of biochemical industry. Background technique [0002] At the end of the 17th century, when people were exploring the special spicy taste of shepherd's purse seeds, they discovered the existence of glucosinolates, referred to as glucosinolates. It was not until the 1830s that two glucosinolates, 2-propenyl glucosinolate and white mustard glucosinolate, were isolated from black mustard and white mustard, respectively. Glucosinolates are composed of β-glucosinolate group, sulfonate aldoxime group and a hydrocarbon group (R). The degradation products of glucosinolates have many functions, some are related to plant flavor, some are related to plant self-protection characteristics such as plant disease resistance, sterilization, and insect resistance, some are related to plant insect-attracting characteristics, and some may be harmful to animals or anim...
