The bright Ti Gong mono- Seed of this Hair even if the high Warm Kill bacterium Office Li Huo System of Yu System Zao Time make the Hou Long phases save in Bu Hui Productivity raw sediment or Zhi Fang Fen From etc., taste Pure, and and Prepare have the coffee Drink material of Jun Li With emulsifications stability processed.This Hair bright coffee Drink material Department whats with added in the coffee extract of sugar decomposition ferment Office reasons the polyglyceryl fatty acid ester institute of degree of polymerization As 2 ~ 5 at coffee Drink material or As Come from the coffee Drink material of at least Ge in the Strip parts that the polysaccharide Class Full foot of the coffee extract in coffee Drink material states (A) ~ (C).(A) 50% or more, the Department that the wave crest face Plot of the fixed polysaccharide Class phase When whats molecular weight 5000 ~ 100000 of Measuring is analysed with the solidifying saturating Layer of Rubber Seepage is managed by the degraded Office of polysaccharide Class and Minus is few.(B there are the molecular weight wave crest Top Dot of polysaccharide Class in the saturating Layer Xi Measuring of) Yi Ning Rubber Seepage fixed molecular weight 1000 ~ 4000.(C) to coagulate the weight average molecular weight As 1000 ~ 6000 that the saturating Layer of Rubber Seepage analyse the fixed polysaccharide Class of Measuring.本發明提供一種即使於製造時之高溫殺菌處理或製造後之長期保存中也不會產生沈澱物或脂肪分離等,口味純,且兼備有制菌力與乳化安定性的咖啡飲料。本發明之咖啡飲料係於以糖分解酵素處理之咖啡萃取液中添加聚合度為2~5之聚甘油脂肪酸酯所成之咖啡飲料,或為來自咖啡飲料中之咖啡萃取物之多醣類滿足下述(A)~(C)的條件中之至少一個的咖啡飲料。(A)以凝膠滲透層析測定之多醣類相當於分子量5000~100000之波峰面積的50%以上,係藉由多醣類低分子化處理而減少。(B)以凝膠滲透層析測定之分子量1000~4000中有多醣類之分子量波峰頂點。(C)以凝膠滲透層析測定之多醣類之重量平均分子量為1000~6000。
