Embodiment 1
[0026] The present embodiment provides a kind of microcapsule of starch-based formula, and the composition and content of microcapsule are as follows:
[0033] The preparation method of the microcapsules provided in this example is the same as the preparation method of Example 1, the difference is that the microcapsules of the starch-based formula in this example, the components and contents of the microcapsules are as follows:
[0034] DHA oil 45.83%, sodium starch octenyl succinate - type A (SSOS-A, molecular weight (1-2) × 10 7g / mol) 9.63%, sodium starch octenyl succinate-model B (SSOS-B, molecular weight 4 g / mol g / mol) 19.25%, sodium ascorbate 6%, tricalcium phosphate 0.6%, sodium citrate 0.01%, and the rest is solid corn syrup.

Abstract
The invention provides a microcapsule with a starch-based formula and application of the microcapsule. In the starch-based microcapsule, a core material is polyunsaturated fatty acidgrease, and a wall material at least comprises first starchsodium octenylsuccinate and second starch sodium octenylsuccinate; the use amount of the polyunsaturated fatty acidgrease is not less than 35%; the molecular weight of the first starch sodium octenylsuccinate is (1-4) * 10 < 7 > g / mol, and the molecular weight of the second starch sodium octenylsuccinate is 5000-7 * 10 < 4 > g / mol. According to the starch-based formula microcapsule and the preparation method thereof, the starch sodium octenylsuccinate with two specific different molecular weights is used as one of the raw materials of the wall materials to be compounded with the core material of the high-content unsaturated fatty acidgrease, and the obtained starch-based formula microcapsule is good in stability and can be well applied to milk powder and infant formula milk powder with higher requirements on product performance.
Description
technical field [0001] The invention relates to the technical field of food additives, in particular to a polyunsaturated fatty acid oil microcapsule and its application. Background technique [0002] Docosahexaenoic acid (DHA) and arachidonic acid (ARA), as important structural components of nerve tissue and retina, are involved in the normal development of the brain and vision. Vascular disease, lower serum total cholesterol and low-density lipoproteincholesterol levels. Although they are optional ingredients, DHA and ARA are added to most of the infant formulas and formulas for special medical purposes on the market for nutritional supplementation. [0003] In order to expand the application of DHA and ARA oils, microencapsulation is often used to increase the stability. DHA and ARA are rich in unsaturated double bonds and are sensitive to oxygen, light and heat, which makes polyunsaturated fatty acid oils easily oxidized and deteriorated. In order to prevent oil oxid...
