Embodiment

[0018] Embodiment: after horseradish is through cleaning, impurity removal, in 35-45 o C is dried at low temperature, crushed into a coarse powder, which can pass through the No. 1 sieve, but cannot pass through the No. 3 sieve. The No. 1 sieve is 10 mesh, and the No. 3 sieve is 50 mesh.

[0019] Preparation of extraction solvent: the ratio of ethyl acetate to water is 1:10-1:20, and the weight of sodium chloride added is 1-2% of the volume of the solution.

[0020] Transfer the horseradish and extraction solvent to a distillation bottle, distill and extract, and control the temperature at 85-95 o C. Under atmospheric pressure, distill for 1-2 hours, collect the distillate, and obtain the ethyl acetate part of the upper layer, that is, the purity of horseradish can reach more than 95% (area normalization method).

[0021] Preparation of the above-mentioned extraction solvent: normal hexane, methylene chloride, ethyl acetate, and ethanol were screened, and it was found that et...

Abstract

The invention discloses a method for extracting allyl isothiocyanate from horseradish. The method comprises 1, horseradish pretreatment: drying horseradish in a low temperature environment at a temperature of 35-45 DEG C, and crushing the dried horseradish by a crusher to obtain crude powder, 2, extraction solvent preparation: preparing a solution from ethyl acetate and water according to a ratio of 1: 10-1: 20, and adding sodium chloride into the solution according to a volume ratio of sodium chloride to the solution of 1-2%, and 3, distillation extraction: adding the horseradish crude powder obtained by the step 1 and the solvent obtained by the step 2 into a distillation flask according to a material-liquid ratio of 1: 10-1: 30 and carrying out distillation for 1-2h. The method utilizes ethyl acetate-water-sodium chloride as extraction solvents to realize distillation extraction. The method can be operated simply, has simple processes and a low cost and is suitable for large-scale industrial production.

Description

technical field [0001] The invention relates to a method for extracting horseradish, in particular to a method for extracting horseradish in horseradish. Background technique [0002] Horseradish is a perennial herb horseradish ( Armoracial apathifolia Gilib.), a class of secondary metabolites extracted from Gilib. It is a volatile, oily liquid at room temperature. Horseradish, which contains -N=C=S group in its chemical structure, is an isothiocyanate compound. It has anti-tumor, bactericidal and insecticidal effects. At present, the methods for extracting and separating horseradish mainly include steam distillation, ultrasonic extraction, supercritical fluid extraction, and macroporous resin column chromatography. [0003] The steam distillation method refers to the co-distillation of plant materials containing volatile components with water, so that the volatile components are evaporated together with the water vapor, and the volatile components are extracted by conden...
