Embodiment 1

[0013] Example 1 Preparation of Zhuge rapeseed oil microcapsules

[0014] The method comprises two steps of preparation of emulsion and preparation of microcapsules, and the specific method is as follows: the crude oil of Zhuge rapeseed obtained by an ultrasonic-assisted extraction method is used as a raw material.

[0015] (1) Prepare the emulsion of microcapsules

[0016] Whey protein (WP) and maltodextrin (Maltodetrin, MD) produced by Henan Qianzhi Trading Co., Ltd. were used as wall materials, and WP and MD were weighed as composite wall materials according to the mass ratio of 2:1. Put it in the DF-101S magnetic stirrer produced by Yuhua Instrument Co., Ltd., Gongyi City, and dissolve it in distilled water at a temperature of 55 ° C to 60 ° C. The amount of distilled water is 5 times the quality of WP, MD and core material; After it is completely dissolved, add Zhuge rapeseed oil according to the amount of Zhuge rapeseed oil and the mass ratio of WP to MD, that is, the c...

[0020] (1) Prepare the emulsion of microcapsules

[0021] Whey protein (WP) and maltodextrin (Maltodetrin, MD) produced by Henan Qianzhi Trading Co., Ltd. were used as wall materials, and WP and MD were weighed as composite wall materials according to the mass ratio of 2:1. Put it in the DF-101S magnetic stirrer produced by Yuhua Instrument Co., Ltd., Gongyi City, and dissolve it in distilled water at a temperature of 55 ° C to 60 ° C. The amount of distilled water is 5 times the quality of WP, MD and core material; After it is completely dissolved, add Zhuge rapeseed oil according to the amount of Zhuge rapeseed oil and the mass ratio of WP to MD, that is, the core-wall ratio is 1:2, and the XHF-D type produced by Ningbo Xinzhi Biotechnology Co., Ltd. Stir in a high-speed disperser and emulsify for 5-10 minutes. The rotation speed of the high-speed disperser is 8r / min. The Zhuge rapeseed oil emulsion prepared has Zhuge rapeseed oil wrapped in the composite wall material and i...

[0025] (1) Prepare the emulsion of microcapsules

[0026] Whey protein (WP) and maltodextrin (Maltodetrin, MD) produced by Henan Qianzhi Trading Co., Ltd. were used as wall materials, and WP and MD were weighed as composite wall materials according to the mass ratio of 1:1. Put it in the DF-101S magnetic stirrer produced by Yuhua Instrument Co., Ltd., Gongyi City, and dissolve it in distilled water at a temperature of 55 ° C to 60 ° C. The amount of distilled water is 4 times the quality of WP, MD and core material; After it is completely dissolved, add Zhuge rapeseed oil according to the amount of Zhuge rapeseed oil and the mass ratio of WP to MD, that is, the core-wall ratio is 1:3, and the XHF-D high-speed tube produced by Ningbo Xinzhi Biotechnology Co., Ltd. Stir in the disperser, emulsify for 5-10 minutes, and the rotation speed of the high-speed disperser is 8r / min. The Zhuge rapeseed oil emulsion prepared has the Zhuge rapeseed oil wrapped in the composite wall materia...

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...
