The present disclosure provides ACE inhibitory peptide composition derived from ginkgo protein and preparation method and application thereof, belonging to the technical field of food and medicine. The ACE inhibitory peptide composition derived from ginkgo protein mainly consists of six small molecular peptides with amino acid sequences of GFDGR (SEQ ID NO. 1), NDPGR (SEQ ID NO. 2), LDQTYRP (SEQ ID NO. 3), REHETIIL (SEQ ID NO. 4), LRMPGPPSDDY (SEQ ID NO. 5) and LRMPGPPSDDYER (SEQ ID NO. 6). The specific preparation process includes preparation of ginkgo protein, hydrolysis of ginkgo protein, enzymolysis and hydrolysis of ginkgo protein to obtain crude ACE inhibitory peptide, and separation and purification of ACE inhibitory peptide composition derived from ginkgo protein.

A probiotic-encapsulating gum Arabic (GA) composite fiber/capsule, including: lactic acid bacteria and an electrospun fiber or electrosprayed capsule, where the lactic acid bacteria are encapsulated in the electrospun fiber or electrosprayed capsule by electro-hydro dynamics (EHD) technology. The electrospun fiber or electrosprayed capsule is prepared by compounding a polymer matrix with GA, and the polymer matrix is polyvinyl alcohol (PVOH), polyvinylpyrrolidone (PVP), whey protein concentrate (WPC) or maltodextrin (MD). A preparation method and an application of the composite fiber/capsule are also provided.

Disclosed is a method of preparing a fermented milk. The method comprises: step 1, extruding whey protein at low temperature, mixing the extruded whey protein with inulin to prepare extruded whey protein isolate (WPI)-inulin composition; step 2, adding sucrose and the extruded WPI-inulin composition into the raw milk, and uniformly mixing and stirring the sucrose, the extruded WPI-inulin composition, and the raw milk to obtain a material A; step 3, preheating, homogenizing, sterilizing and cooling the material A to obtain a fermentation substrate; step 4, adding a fermentation agent into the fermentation substrate, filling the fermentation substrate in a container, and then performing heat-preserved fermentation, and ending the fermentation to obtain a material B; step 5, cooling the material B, and then refrigerating the material B to obtain fermented milk.
