A milk-derived basic protein fraction and a basic peptide fraction are provided for use as an effective component for agents for improving lipid metabolism and reducing high blood pressure which can be administered orally, are effective with a relatively small dosage, have good taste and are stable during storage.

Agents for improving lipid metabolism and reducing high blood pressure

A milk basic protein fraction is heated if necessary, the resulting precipitate is removed to recover the resulting supernatant, alcohol is added to this supernatant, a fraction containing a high concentration of milk basic cystatin is recovered by removing the resulting precipitate and brought into contact with a carrier containing a sulfuric acid group, such as heparin, to recover a fraction which is not adsorbed onto the carrier, and this fraction is then treated with an ultrafiltration membrane having an cut-off molecular weight of 10-50 kDa to recover the permeate to produce a fraction containing a high concentration of milk basic cystatin. Alternatively, a milk-derived basic protein composition is brought into contact with an anion exchange resin to recover a fraction which is not adsorbed onto the resin, after which this fraction is brought into contact with a cation exchange resin to recover the target fraction by eluting a fraction which is adsorbed onto the resin with an eluent to produce a fraction containing a high concentration of milk basic cystatin. Further, a decomposition product of the fraction containing a high concentration of milk basic cystatin is produced by decomposing this fraction containing a high concentration of milk basic cystatin with protease.

Method of producing fractions containing a high concentration of milk basic cystatin and decomposition products thereof

The present invention is to provide a novel medicine, drink, food or feed having an action of strengthening bone. More specifically, the present invention is to provide a medicine, drink, food or feed combined with collagen, fraction containing collagen or degradation product thereof. Fraction containing collagen was prepared by mincing skin corium layer into pieces, defatting it and lyophylization or by pulverizing bone, decalcifying it and lyophylization. Oral administration of these can stimulate proliferation of osteoblast, inhibit bone resorption and strengthen bone. They can be useful for improvement of osteoporosis, bone fracture, bone pain, etc.
