Problems solved by technology

[0004] Antarctic krill oil is sensitive to light, oxygen and heat, prone to oxidation, and its hydrophobic properties limit its application in food
At present, most Antarctic krill oil exists in the form of capsules, and there is still a lack of effective means to apply it to water-soluble foods

Abstract

The invention discloses a euphausia superba oil nanostructure lipid carrier. The euphausia superba oil nanostructure lipid carrier is prepared from, by mass, 3.5-6.5% of euphausia superba oil, 3.5-6.5% of solid lipid, 0.9-1.1% of emulgator and the balance water. The invention further provides a preparing method of the euphausia superba oil nanostructure lipid carrier. The preparing method includes the following steps that 1, the solid lipid and the euphausia superba oil are fused and mixed; 2, the emulgator is added into water and stirred until the emulgator is dissolved; 3, under the magnetic stirring condition, the fused mixed lipid is dripped into a water solution obtained in the step 2 while the lipid is hot; 4, primary emulsion obtained in the step 3 is homogenized; 5, the micro emulsion obtained after homogenizing in the step 4 is naturally cooled to the room temperature to obtain an aqueous dispersion of the euphausia superba oil nanostructure lipid carrier. Storage stability and bioavailability of the euphausia superba oil can be improved, and application of the euphausia superba oil to water-soluble food is broadened.

Description

technical field [0001] The invention relates to a preparation method of an Antarctic krill oil nanostructure lipid carrier. Background technique [0002] Antarctic krill oil is obtained from wild Antarctic krill in pure sea areas, which contains a large amount of phospholipids, omega-3 polyunsaturated fatty acids, astaxanthin, vitamins A, D, E, animal flavonoids, chitin and trace elements And other active substances, safe and non-toxic side effects. And a large number of studies have shown that Antarctic krill oil is the only natural omega-3 combined with phospholipids in nature, and then bonded with super natural antioxidants, which has both high bioavailability and super antioxidant power. Active multi-functional complex molecules, and its phospholipids are very close to those of human cells, so phospholipids rich in omega-3 polyunsaturated fatty acids are very easy for the body to absorb and utilize. At present, research on Antarctic krill oil at home and abroad is main...
