Preparation method of orychophragmus violaceus seed oil microcapsules

Abstract

The invention relates to a preparation method of orychophragmus violaceus seed oil microcapsules. The preparation method comprises the following steps of (1) preparing a microcapsule emulsion: using whey protein (WP) and maltodextrin (MD as wall materials, weighing WP and MD in proportion by mass as a composite wall material, placing the weighed WP and MD in a magnetic stirring machine, enabling the WP and the MD to dissolve in distilled water successively, and after the WP and the MD thoroughly dissolve, performing stirring in a high speed disperser so as to prepare the orychophragmus violaceus seed oil emulsion for standby application; and (2) preparing the orychophragmus violaceus seed oil microcapsules: placing the emulsion in a spray drying machine, performing spray drying under the set condition, after drying is completed, collecting microcapsule powder with a self-sealed plastic bag, and placing the collected microcapsule powder in a refrigerator for storage, so that the orychophragmus violaceus seed oil microcapsules are obtained. According to the method disclosed by the invention, the problem that orychophragmus violaceus seed oil is easy to oxidize and sour in the storageprocess, is solved, and the condition is provided for maintaining the quality of the orychophragmus violaceus seed oil. The preparation method is suitable for regions where orychophragmus violaceus is enriched, so that the utilization rate of orychophragmus violaceus resources is increased, and the orychophragmus violaceus seed oil microcapsules can provide health for people.

Description

technical field [0001] The invention relates to rapeseed oil, and also to microcapsules, in particular to the preparation of Zhuge rapeseed oil microcapsules. Background technique [0002] Zhuge vegetable (Orychophragmus violaceus) is a plant of Brassicaceae, genus Zhuge, and Brassica, also known as February blue. Zhuge vegetable contains protein, sugar, crude fiber, vitamins (B, C), carotene, vitamin P and other vitamins, and its fat content is very low. It is the best health food for weight loss. The stems and leaves contain flavonoids, which can inhibit tumors, protect the liver, and prevent cardiovascular diseases. It contains eight kinds of amino acids needed by the human body. Moreover, Zhuge vegetable is widely distributed in our country and is rich in resources. It is a new vegetable provenance with great development potential. Zhuge Cai is a common wild vegetable in northern China. Its young leaves and stems are edible, and its seeds can be collected for oil extr...
