Abstract

The invention relates to the technical field of spirulina protein peptide, in particular to a spirulina protein peptide refining and spray drying microencapsulation industrial method, which can obtainspirulina protein peptide powder with good absorption, good dissolution, no fishy smell, no bitter taste and no salty and astringent taste, expands the application range of spirulina in medicines andhealth-care foods, and is suitable for beverage and other beverages. The method comprises the following steps: s1, pretreating a ceramic filter element; s2, carrying out ultrafiltration; s3, carryingout nanofiltration; s4, preparing spirulina protein peptide spray drying feed liquid; s5, material liquid pretreatment; s6, spray drying and embedding; s7, carrying out secondary drying; s8, vacuumizing, filling nitrogen and packaging; micromolecular spirulina protein peptide is obtained through ultrafiltration, monovalent cations such as sodium are removed through filtration of a nanofiltrationmembrane, spirulina protein peptide microcapsule embedding powder is obtained through a spray drying method, fishy smell, bitter taste and salty and astringent taste are removed, and the obtained spirulina protein peptide microcapsule contains various active peptides and has the advantages of being good in absorption, good in dissolution, no fishy smell, no bitter taste and no salty and astringenttaste.

Description

technical field [0001] The invention relates to the technical field of spirulina protein peptides, in particular to an industrial method for refining and spray-drying microencapsulation of spirulina protein peptides. Background technique [0002] Spirulina (Spirulina) belongs to the Cyanophyta, Oscillatoriaceae, is a kind of spiral-shaped prokaryotic algae composed of single cells or multi-cells, and is an ancient organism that has existed on the earth for 3.5 billion years. The protein content of spirulina is as high as 60-70%, and it is also rich in VA, VB and minerals. Recommended by the Food and Agriculture Organization of the United Nations (FAO): "the most ideal food in the 21st century"; determined by the World Health Organization (WHO) as "the best health product for human beings in the 21st century"; in 1972, it was recognized at the second international microbial protein conference: "Super nutritious food in the future"; recognized by the United Nations World Food...
