[PROBLEMS] To clarify the amino acid sequence of a region having a high cholesterol-reducing activity in soybean protein, to provide a peptide comprising the amino acid sequence, a cholesterol-reducing agent containing the peptide as an active ingredient, and to impart cholesterol-reducing activity. Provided are foods and drinks, feeds, food and drink additives and feed additives. Kind Code: A1 Abstract: Various deletion mutant peptides are prepared mainly around the region of Ile114-Arg161 in the Ala subunit of soybean protein, and the cholesterol-reducing activity is examined by examining the binding ability and affinity for each bile acid. Amino acid sequence Val Ala Trp Trp Met Tyr was revealed. According to the present invention, it is possible to provide the peptide, a cholesterol-reducing agent containing the peptide as an active ingredient, a food or drink, a feed, a food or drink additive, and a feed additive having a cholesterol-reducing activity.
