摘要：
PURPOSE: A natural antibacterial composition is provided to contain glycomacropeptide hydrolysate including natural N-acetylneuraminic acid as an active ingredient by using microorganisms applicable for infant food. CONSTITUTION: A natural antibacterial composition includes glycomacropeptide hydrolysate； and carbon number 6-12 medium-chain fatty acid or its ester compound as an active ingredient. Glygopeptide hydrolysate is manufactured by reacting neuraminidase separated from Arthrobacter ureafaciens KCTC 3387； and glycomacropeptide or protein containing glycomacropeptide. The glycomacropeptide hydrolysate includes 4-99 weight% of N-acetylneuraminic acid. The glycomacropeptide hydrolysate is manufactured by adding neuraminidase of 0.09-0.02 U per 1 g of glycomacropeptide to the reacting solution containing 3-8 weight% of glycomacropeptide, and reacting at 35-55deg.C, pH 4-5 for 2-5 hours. The carbon number 6-10 medium-chain fatty acid or its ester compound is at least one selected from caproic acid, caprylic acid, capric acid and their ester compounds. The glycomacropeptide hydrolysate contains 0.01-10 weight% of N-acetylneuraminic acid and carbon number 6-10 medium-chain fatty acid or its ester compound 0.01-10 weight%. Infant food contains the natural antibacterial composition 0.08-1 weight% in the formula 100 weight% which is diluted or formed so that infants are able to intake.본 발명은 N-아세틸뉴라민산을 포함하는 글리코마크로펩티드 뉴라미니다아제 분해물을 유효성분으로 하는 천연 항균제 조성물에 관한 것으로, 본 발명의 천연 항균제 조성물은 영유아식에 적용하기 안전할 뿐만 아니라, 영유아식에 혼입될 경우 영유아의 건강에 위해를 가할 수 있는 엔테로박터 사카자키나 바실러스 세레우스에 대하여 우유가 포함된 경우에도 그 항균활성이 저하되지 않음으로서, 영양이 강화되고 보다 안전한 우유함유 영유아식의 제조가 가능하다.
