焙煎コーヒー豆の微粉砕物が、コーヒーの呈味を付加する素材として、例えば、コーヒー抽出物、インスタントコーヒー、缶コーヒー、アイスクリーム、菓子、パン等に添加されて利用されている。また、茶葉の微粉砕物が、過度な渋味を有しながらも、旨味やコク味をより一層強く感じさせることができる素材として、緑茶飲料、紅茶飲料、アイスクリーム、菓子、パン等に添加されて利用されている。 The finely ground roasted coffee beans are used as a material for adding the taste of coffee by being added to, for example, coffee extract, instant coffee, canned coffee, ice cream, confectionery, bread and the like. In addition, finely ground tea leaves are added to green tea beverages, black tea beverages, ice cream, confectionery, bread, etc. as a material that can make the taste and richness even stronger while having an excessive astringency. It has been used.

焙煎コーヒー豆の微粉砕物に関して、特許文献1には、レシチン及びポリグリセリン脂肪酸エステルの乳化剤と平均粒子径が2μm以下のコーヒー豆微粉砕品とを含有するコーヒー風味強化剤が記載されている。しかし、レシチン及びポリグリセリン脂肪酸エステルは、酸性下で安定ではないため、コーヒーの通常のpH4.5〜5.5で、あるいはアスコルビン酸等の酸性の酸化防止剤を添加した場合に、コーヒー豆微粉砕品を乳化できなくなるという問題がある。 Regarding the finely ground coffee beans, Patent Document 1 describes a coffee flavor enhancer containing an emulsifier of lecithin and polyglycerin fatty acid ester and a finely ground coffee beans having an average particle size of 2 μm or less. .. However, since lecithin and polyglycerin fatty acid esters are not stable under acidic conditions, coffee beans are fine at the usual pH of 4.5 to 5.5 of coffee or when an acidic antioxidant such as ascorbic acid is added. There is a problem that the crushed product cannot be emulsified.

特許文献2には、焙煎コーヒー豆と水とを粉砕機に入れて粉砕してペースト状分散液とする粉砕工程、及び前記ペースト状分散液を乾燥して粉末レギュラーコーヒーとする乾燥工程とを備えた粉末レギュラーコーヒーの製造方法が記載されている。しかし、特許文献2には、微粉砕コーヒー豆を分散させるための乳化剤の使用については一切、記載されていない。 Patent Document 2 describes a crushing step of putting roasted coffee beans and water in a crusher and crushing them into a paste-like dispersion, and a drying step of drying the paste-like dispersion to make powder regular coffee. The method for producing the prepared powdered regular coffee is described. However, Patent Document 2 does not describe the use of an emulsifier for dispersing finely ground coffee beans.
