Abstract

The invention provides a preparation device and a preparation method for DHA algal oil HIPE (high internal phase emulsion) gel and belongs to the field of food processing. HIPE is prepared from 90% byvolume of DHA algal oil as an oil phase as well as 10% by volume of a heat-denatured whey protein isolate solution and 0.5%(w / w) gluconolactone as an aqueous phase on the basis of a high-pressure microjet granulator, and DHA algal oil HIPE gel beads are prepared by adding sodium alginate and calcium chloride. The DHA algal oil is wrapped in the gel beads layer by layer, loading of the algal oil is increased, oxidation resistance and stability of the algal oil are improved, odor of the DHA algal oil can be well covered, the slow release effect of the DHA algal oil gel beads in a human body isrealized, and bioaccessibility of the DHA algal oil gel beads is improved.

Description

[0001] Technical field: The present invention designs a DHA algae oil high internal phase emulsion gel preparation device and its preparation method, belonging to the field of food processing. Background technique [0002] Docosahexaenoic acid (DHA), a polyunsaturated fatty acid that is very important to the human body, plays an important role in the growth and maintenance of nervous system cells. Studies have shown that DHA algae oil has good antioxidant properties and can promote the prevention of cardiovascular and cerebrovascular diseases. DHA algae oil is also particularly important for the development of children's intelligence and vision. However, the naturally extracted DHA algae oil has an unpleasant smell and is difficult to swallow; and the DHA algae oil has low stability and bioacceptance rate, and is easily oxidized and decomposed during processing. [0003] A high internal phase emulsion means that the volume fraction of the dispersed phase in the O / W emulsion is...
