Abstract

The invention discloses an extraction of high activity milk thistle oil and a preparation method of a microcapsule of high activity milk thistle oil, and belongs to the technical field of biological processing. The preparation method comprises following steps: taking milk thistle seeds as the raw material, grinding milk thistle seeds, extracting milk thistle seeds by a mixed solvent composed of petroleum ether and anhydrous ethanol under the assistance of ultrasonic waves, carrying out centrifugal separation, vacuum concentration, and drying to prepare the high activity milk thistle oil; taking the milk thistle oil as the core material, carrying out emulsification by using an emulsifier glycerol stearate, taking soy isolate protein and Arabic gum as the wall material, and performing dissolving, homogenizing, re-agglomerating, centrifuging, and freeze-drying to obtain the milk thistle oil microcapsule. Under the assistance of ultrasonic waves, a mixed solvent is used to extract milk thistle seeds, the extraction time is short, the activity of the oil is obviously enhanced; the air in the microcapsule is expelled, unsaturated fatty acids in the oil are protected, the stability is improved, and the shelf life is prolonged. Moreover, the microcapsule has the advantages of good flowing property and good brewing property and is convenient to use, the product forms are enriched, andapplication range of the milk thistle oil is enlarged.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a method for extracting highly active milk thistle oil and preparing microcapsules thereof. Background technique [0002] Milk thistle is a herbaceous plant of the genus Milk thistle in the family Asteraceae, and is an excellent medicinal plant and oil plant. Milk thistle seeds contain about 3.0% to 5.0% silymarin and 20% to 30% milk thistle oil. The medicinal active ingredient of milk thistle is silymarin, which has the functions of protecting the liver, anti-oxidation, lowering blood fat, and anti-cancer. Since milk thistle oil was approved as a new resource food by the Ministry of Health in 2014, it has gradually attracted the attention of researchers. In milk thistle oil, oleic acid accounts for 20% to 40%, linoleic acid accounts for 30% to 70%, and the total unsaturated fatty acid is as high as more than 80%. In addition, it also contains β-sitosterol, stigmasterol and other s...
