An oyster peptide with an effect of improving sexual function and a preparation method thereof are provided, the oyster peptide at least includes peptide segments RI, IR and VR in its composition. Based on a mass of the oyster peptide, a content of the RI is ≥3.60 mg/100 g, a content of the IR is ≥7.60 mg/100 g, and a content of the VR is ≥6.50 mg/100 g.

Oyster peptide with effect of improving sexual function and preparation method thereof

A selenium-chelating pea oligopeptide, a preparation method thereof and use thereof. After the selenium-chelating pea oligopeptide is subjected to digestion treatment in at least one of following three ways, a change rate of selenium content not more than 3% with respect to the selenium content before the digestion treatment: hydrolyzing for 4 hours by a pepsin at a pH value of 2 and a temperature of 37° C.; hydrolyzing for 6 hours by a trypsin at a pH value of 7.5 and a temperature of 37° C.; maintaining the temperature constant at 37° C., firstly hydrolyzing for 4 hours by the pepsin at a pH value of 2, and then continuing to hydrolyze for 6 hours by a trypsin at a pH value of 6.8. The preparation method thereof includes mixing and reacting an aqueous solution of pea oligopeptide and sodium selenite, and then being subjected to alcohol precipitation and drying.
