Embodiment 1

[0017] (1) Raw material pretreatment: select 20 kg of red radish with dark color, no frostbite, no rot, no pests and diseases, wash to remove impurities such as sediment, wash with 5% ozone water, and cut into pieces;

[0018] (2) Solvent extraction: use 90% ethanol as the extraction solution, set the extraction temperature at 60°C according to the solid-liquid ratio of 1:8, and repeat the extraction three times, each time for 3 hours;

[0019] (3) Filtration and adsorption: filter the extract under reduced pressure, put the clarified radish red pigment solution on the AB-8 macroporous resin adsorption column with a height of 3m, a diameter of 0.8m, and 300kg of resin, with a feed flow rate of 2kg / min for adsorption;

[0020] (4) Centrifugal extraction: Centrifuge the above liquid at 2500r / min for 8min to extract;

[0021] (5) Concentration: Immerse the raw material in ethanol solvent with a volume concentration of 70% according to the solid-liquid ratio of 5g / ml, then contr...

Abstract

The invention relates to a method for extracting mustard oil from a red-core radish. The method comprises the following steps: (1) pre-treatment of raw materials; (2) solvent extraction; (3) filtering adsorption; (4) centrifugation extraction; and (5) concentration. According to the invention, a solvent-extraction method is adopted; the soaking time and pigment impurities are effectively controlled; the technology is simple compared with the prior art; and the pigment extraction rate is improved. The obtained pigment is high in purity and has a bright color. Isorhodanate is extracted from radish waste residue, so that a valuable product of isorhodanate can be obtained, and comprehensive utilization value of the red-core radish can be improved.

Description

technical field [0001] The invention belongs to the technical field of pigment extraction, and in particular relates to a method for extracting mustard oil from radish. Background technique [0002] Canola oil is a unique Canadian canola oil. Due to the use of traditional production and processing techniques to change the fatty acid composition of the oil, it is very different from ordinary rapeseed oil. Canola oil is widely used in the United States and Canada, but has not been promoted in Europe. Mustard oil can promote the metabolism of fatty substances in the human body, thereby preventing the accumulation of fat under the skin. [0003] White radish contains natural mustard oil, which has a spicy taste and is usually hidden in the skin and meat cells, so when eating raw radish, the cell wall is broken, and the mustard oil will make people feel spicy when it touches the taste nerve. The distribution of mustard oil in the radish is very uneven, and the cortex generally...
