Embodiment 1

[0028] To prepare rosehip seed oil:

[0029] After the rosehip seeds are crushed, they are extracted with supercritical fluid; the extraction temperature is 50°C, the separation 1 temperature is 50°C, the separation 2 temperature is 35°C, the extraction pressure is 25Mpa, the separation 1 pressure is 8Mpa, and the separation 2 pressure is 4.5Mpa.

Embodiment 2

[0031] Prepare the wall material composition:

[0032] Mix starch octenyl succinate and maltodextrin uniformly according to the mass ratio of 1:1, 2:1, 3:1, and 4:1, respectively, to obtain wall material compositions 1, 2, 3, and 4;

[0033] Starch octenyl succinate, maltodextrin and sodium tripolyphosphate were uniformly mixed at a mass ratio of 4:0.5:0.05 to obtain wall material composition 5.

Embodiment 3

[0035] The rosehip seed oil prepared in Example 1 is used as the core material, and the wall material composition 1-5 prepared in Example 2 is used as the wall material respectively, and the rosehip seed oil microcapsules 1-5 are prepared by the following method;

[0036] (1) Preparation of wall material solution

[0037] Dissolve the wall material composition in distilled water at 40°C with a solid content of 15% by weight;

[0038] (2) Mixture preparation

[0039] After adding 25% rosehip seed oil (relative to the total mass of the wall material and the core material) to the wall material liquid, use a disperser at 10000r / min high-speed shear for 3min to obtain a mixed solution;

[0040] (3) homogeneous

[0041] Pour the mixed liquid into a homogenizer with a pressure of 40MPA and homogenize twice to obtain a stable emulsion;

[0042] (4) spray drying

[0043] The emulsion is spray-dried, the air inlet temperature is 180°C, the outlet temperature is 80°C, and finally the...

Abstract

The invention relates to a method for preparing rose hip seed oil microcapsules, and belongs to the technical field of microcapsule preparation. According to the preparation method, rose hip seed oil is used as a core material, and the following wall material composition is used as a wall material. The dosage of the core material is 20%-30% of the total mass of the core material and the wall material composition, and the wall material composition is composed of alkenyl succinic acid starch ester and maltodextrin according to the mass ratio of 1-4:1. According to the method, the maltodextrin and the alkenyl succinic acid starch ester are mixed according to the mass ratio of 1:1-4 and then are used as the wall material, the performance of the alkenyl succinic acid starch ester serving as the wall material can be improved, and thus the rose hip seed oil microcapsules without obvious sunken parts on the surfaces and with even particles are prepared.

Description

technical field [0001] The invention relates to a method for preparing rosehip seed oil microcapsules, which belongs to the technical field of microcapsule preparation. Background technique [0002] Rosehip is a fleshy berry developed from the receptacle after the rose has withered. It belongs to a false fruit. As a member of the Rosaceae family, it has been used as food or medicine. Studies have shown that rose hips are rich in terpenoids, V E , unsaturated fatty acids and other active ingredients. Rosehip seeds are particularly rich in unsaturated fatty acids, among which unsaturated fatty acids account for more than 90% of the total fat, mainly including oleic acid, linoleic acid, and linolenic acid. This shows that rosehip seed oil has high development value and can be applied to the development of nutritional health products. [0003] A large number of unsaturated fatty acids in rosehip seeds are easily oxidized and rancid, thereby reducing the nutritional value of r...
