Abstract

The invention discloses a preparation technique of a high-oil-load DHA (docosahexaenoic acid) algae oil microcapsule powder. The whole microcapsule powder is composed of 48-65 wt% of outer layer wall material, 33-50 wt% of core material, 1.2-1.5 wt% of emulsifier and 0.5 wt% of antioxidant. The preparation technique comprises the following steps: dissolving the outer layer wall material and emulsifier in water, uniformly mixing at 50-60 DEG C, carrying emulsification shearing to obtain a pre-emulsified solution, adding the core material and antioxidant, continuing the emulsification shearing, homogenizing twice with a high-pressure homogenizer under the pressure of 40-60 MPa to obtain an end emulsion, and carrying out spray drying on the end emulsion to obtain the high-oil-load DHA algae oil microcapsule powder, wherein the air inlet temperature for the spray drying is 180-210 DEG C, and the air outlet temperature is 80-100 DEG C. The microcapsule powder can protect the primary characteristics of the DHA, enhance the stability of the DHA and prolong the shelf life, and thus, has an important action on enhancing the utilization ratio of the DHA and widening the application range of the DHA.

Description

technical field [0001] The invention relates to a DHA algae oil microcapsule powder with high oil loading and a preparation process thereof. Background technique [0002] DHA, also known as "brain gold", its full name is Docosahexaenic Acid (Docosahexaenic Acid), and its molecular formula is C 22 h 32 o 2 , with a molecular weight of 328.49, is an Omega-3 (ω-3) polyunsaturated fatty acid, which is difficult for the human body to synthesize and must be ingested from the outside. The main producer of fatty acids in the marine food chain is marine algae. High levels of DHA have been found in many plant plankton and seaweed. In addition to marine algae, some marine microorganisms have also been found to have the ability to synthesize DHA, especially in The fat of certain lower fungi and bacteria is rich in DHA (such as Mucrales, Thaustochytrium, Schizochytrium, Entomophthora obscyura, etc.), and some marine fungi are particularly rich in DHA, such as DHA in Thraustochytrium a...
