The invention provides lipid rich in
sphingomyelin, a preparation method and a
phospholipid ingredient for
infant formula milk
powder, and relates to the technical field of dairy
product processing.The lipid rich in
sphingomyelin and the preparation method thereof have the advantages that primary separation is carried out by the aid of
supercritical carbon dioxide extraction technologies, secondary extraction is carried out by the aid of follow-up ethyl
alcohol serving as entrainer, non-polar lipid can be effectively removed, and the lipid rich in
sphingomyelin can be obtained; and phospholipids with high polarity, especially sphingomyelin, are retained. The
ethanol concentration is controlled to be 20% (v / v), so that the
solubility and the selective extraction efficiency of lipid rich in sphingomyelin are improved, and a higher sphingomyelin enrichment degree is realized in a final product. Meanwhile,
ethanol extraction can be directly combined with a freezing
crystallization method, other organic solvents are not introduced into the method, the method is green and safe, complex equipment support is not needed, the technological process is short, operation is easy and convenient, cost is low, and the method is suitable for rapid preparation.
