Embodiment 1～4

[0033] The preparation method of embodiment 1~4 comprises the following steps:

[0034] 1. Preparation of oil phase:

[0035] Quantitatively weigh algae oil DHA, vitamin E oil, VC palmitate, carnosic acid, citric acid, and lecithin;

[0036] Use a small amount of algae oil DHA to completely dissolve the Vc palmitate at a temperature of 90-95°C (stir while adding until the algae oil DHA is completely transparent and clear). When the algal oil DHA is completely transparent and clear, add carnosic acid to continue dissolving until the algal oil DHA is completely transparent and clear. Add most of the remaining algal oil DHA, vitamin E oil, lecithin and citric acid into the oil phase tank to control the temperature at 50±3°C, and then add the above-mentioned algal oil DHA (dissolved DHA oil, Vc palm Ester, carnosic acid), and at the same time turn on the shearing machine and stir at 50±3°C for 15-20 minutes to fully mix the materials.

[0037] 2. Preparation of emulsifier:

Abstract

The invention relates to an algal oil DHA (Docosahexaenoic Acid) microcapsule, which consists of algal oil DHA, an antioxidant and a shell material. The antioxidant is prepared from VC (Vitamin C) palmitate, lecithin, carnosic acid, VE (Vitamin E) grease and citric acid based on the mass ratio of (40-60):(25-35):(5-10):(3-7):1 sequentially, and the dose of the antioxidant is 0.6-1.2% of the mass of the algal oil DHA; the shell material is prepared from modified starch, Arabic gum, cane sugar, maltose and vitamin C-sodium based on the mass ratio of (10-30):(5-10):(1-5):(1-3):1 sequentially, and the dose of the shell material is 60-70% of the mass of the algal oil DHA. The invention further discloses a preparation method of the algal oil DHA. According to the invention, the oxidation of the algal oil DHA is effectively slowed down, odor smell is covered, the stability of products is increased and the effect duration is prolonged.

Description

technical field [0001] The invention relates to a preparation and a preparation method thereof, in particular to an algal oil DHA microcapsule and a preparation method thereof. Background technique [0002] DHA (docosahexaenoic acid) is a polyunsaturated fatty acid that is very important to the human body. It is a major element for the growth and maintenance of nervous system cells. It is an important component of the brain and retina. It enhances memory and thinking. It plays a significant role in improving ability and improving intelligence, especially for the development of intelligence and vision of fetuses. There are two types of DHA currently on the market: one is extracted from deep-sea fish oil, and the other is extracted from algae. The former is derived from fish fat, and the content of EPA (eicosapentaenoic acid) is too high, which can make the proportion of DHA too low, which is quite different from breast milk and does not meet the physiological needs of childr...
