PROBLEM TO BE SOLVED: To enable the simple obtaining of the subject flavor, having a light taste and an aftertaste good in cutoff, capable of imparting natural flavor and taste and excellent in impartment of especially a raw milky feeling by bringing a cow's milk into contact with an adsorbent and then eluting the adsorbed component from the adsorbent with an ethyl alcohol solution. SOLUTION: A cow's milk is brought into contact with an adsorbent (preferably a packing for reversed phase chromatography such as a chemically bound type silica gel or a porous polymer) and the adsorbed component is then eluted from the adsorbent with an ethyl alcohol solution (preferably 99.5% ethyl alcohol or 95% ethyl alcohol). The cow's milk is preferably a homogenized and high- temperature sterilized milk having 3.5-4.2% milk fat component is preferred or the cow's milk retaining a raw milk feeling is preferably used. The contact of the cow's milk with the adsorbent is preferably conducted at 10-30 deg.C temperature and 1-200 liquid passage speed SV of the cow's milk by a method for packing the adsorbent and passing the cow's milk therethrough. The contact time may usually be 0.5-3 hr. |
