Problems solved by technology

However, the above two methods use materials that are not in the list allowed in the appendix of GB / T 19630.2
Therefore, since such traditional microcapsules all use emulsifiers or wall materials that are not allowed to be used in the GB / T 19630.2 appendix, it is difficult for the prepared microcapsules to be used in the manufacture of organic food, otherwise it will cause damage to organic integrity. influences

Abstract

The invention relates to a method for preparing organic food processing standard meeting fish oil microcapsules. The method comprises the following steps: taking a sodium alginate solution, adding sesame meal and fish oil, mixing above materials until the materials are uniform, and carrying out high pressure homogenization to form a stable emulsion; carrying out pressure spraying on the emulsion, and allowing atomized small droplets to fall into a calcium chloride solution in order to form fish oil microcapsules; and fully solidifying the fish oil microcapsules, separating wet microcapsules, washing the wet microcapsules with distilled water to remove residual calcium chloride, carrying out gradient dehydration drying with ethanol, and carrying out sealed packaging. Raw materials adopted in the invention accord with requirements in a list in GB / T 19630.2 Appendix, and are processed at a low temperature in the presence of N2 to prepare the fish oil or DHA or EPA microcapsules; the above prepared products accord with organic food processing standards; the microcapsules have the advantages of good structure form, compact surface, uniform particles, high embedding rate, no residual oil and super strong stability; and the method is of great significance to widen the application of the fish oil capsules and solve the processing problems of organic foods.

Description

technical field [0001] The invention relates to a method for preparing fish oil microcapsules meeting organic food processing standards. Background technique [0002] Fish oil is rich in essential omega-3 polyunsaturated fatty acids docosahexaenoic acid (DoeoseHexaenoieacid, DHA) and eicosapentaenoic acid (EieosaPntemacioeaeid, EPA). Among them, EPA is called "vascular scavenger", which has the functions of dredging and cleaning the cardiovascular system, reducing serum cholesterol and low-density lipoprotein levels in the human body, improving high blood pressure, and preventing arteriosclerosis and other diseases; DHA, commonly known as "brain gold", has the function of improving Memory, help infants and young children intellectual development, prevent senile dementia, improve vision and other physiological functions. [0003] EPA and DHA contain multiple double bonds, which are extremely sensitive to light, heat and oxygen, and usually require low temperature, airtight a...
