Abstract
The present invention discloses a highly unsaturated fatty acid rice bran oil microcapsule which includes the raw materials of material A, material B, microcapsule wall materials and emulsifiers. The present invention also discloses a highly unsaturated fatty acid rice bran oil microcapsule preparation method which comprises the following steps: processing the material A to obtain mixed materials, spraying and wetting the mixed materials with water, and allowing the wet mixed materials to stand still to obtain a first material; processing the first material by enzyme deactivation steaming to obtain a second material; processing the second material once again to obtain a free oil 1, a second material and residues; putting the second material into a second processing equipment, increasing the temperature of the second processing equipment and the contents, and centrifuging and separating after incubation to obtain a free oil 2; putting the free oil 1 and free oil 2 into a third processing equipment, dewaxing, degumming, deacidifying, and discoloring to obtain the highly unsaturated fatty acid rice bran oil; and then conducting mixing and shearing of the highly unsaturated fatty acid rice bran oil, the material B and the microcapsule wall materials, and drying to obtain the highly unsaturated fatty acid rice bran oil .
Description
Technical field
The present invention relates to vegetable oil technical field, particularly relate to a kind of high unsaturated fatty acid rice bran oil micro-capsule and preparation method thereof.
Background technology
Rice bran oil is owing to more and more receiving the concern of people containing the unrighted acid up to more than 70%, many enterprises are by adding fat-soluble nutrients material to strengthen the edibility of rice bran oil, but unrighted acid to light, thermoae be responsive, easily by dioxygen oxidation in air.Therefore, how while raising rice bran oil nutritive value, ensure rice bran oil Middle nutrition material not change by external environment the emphasis direction becoming research at present.
Summary of the invention
Based on the technical problem that background technology exists, the present invention proposes a kind of high unsaturated fatty acid rice bran oil micro-capsule and preparation method thereof, the present invention is comprehensively nutritious, the high and balanced proportion of unsaturated fatty acid content, has the effect reducing blood fat, eliminate cholesterol; Have effect of warm zang-fu differentiation, tonifying Qi kidney-nourishing concurrently.
It should be noted that, in the present invention, TBHQ is ditert-butylhydro quinone, belongs to national regulation and allows a small amount of edible antioxidant added.
A kind of high unsaturated fatty acid rice bran oil micro-capsule that the present invention proposes, its raw material comprises 100 parts of material A, 5-8 serving material B, 20-30 part micro-capsule wall material and 1-3 part emulsifying agent by weight;
Material A comprises by weight: rice bran 200-230 part, linseed 70-80 part, maize germ 55-60 part, walnut kernel 35-40 part, grape pip 25-30 part, carrot 20-23 part, tealeaves 16-19 part, rosemary 7-10 part, rhizoma atractylodis 5-8 part, Chinese prickly ash 3-6 part, eupatorium 2-5 part, Amomum cardamomum 2-4 part, tsaoko 2-3 part, Chinese cassia tree 1.5-2 part, cortex acanthopanacis 1-2 part, Chinese cassia tree 1-1.5 part;
Material B comprises by weight: lycopene 0.01-0.05 part, Ascorbyl Palmitate 0.02-0.04 part, TBHQ 0.3-0.5 part.
Preferably, in material A, the weight ratio of rice bran, linseed, maize germ, walnut kernel, grape pip is 210-220:75-78:56-58:36-38:26-27.
Preferably, in material A, the weight ratio of carrot, tealeaves, rosemary, rhizoma atractylodis, Chinese prickly ash, eupatorium, Amomum cardamomum, tsaoko, Chinese cassia tree, cortex acanthopanacis, Chinese cassia tree is 21-22:17-18:8-9:6-7:4-5:3-4:2.5-3:2.3-2.6:1.6-1.8:1.2-1. 5:1.1-1.3.
Preferably, emulsifying agent comprises 1-3 part molecule distillating monoglyceride and 3-6 part sucrose fatty ester by weight.
Preferably, the preparation method of micro-capsule wall material is: 55-60 part Arabic gum, 110-120 part maltodextrin and 200-220 part distilled water are mixed by weight, be warming up to 60-65 DEG C, and insulation 10-15min obtains micro-capsule wall material.
