ここで、異味・異臭とは、焙煎コーヒー豆由来の焦げ臭や苦味、ならびに生コーヒー豆由来のエグ味や青臭み等をいう。焙煎コーヒーは特有の焦げ臭や苦味を有しており、その嗜好性は高いものの、焙煎コーヒー豆そのものやその抽出物を他の食品等へ配合する際にはその味と香りが違和感を与えるため、食品の種類によっては好ましくない場合がある。また生コーヒー豆は特有のエグ味や青臭みを有するため、生コーヒー豆そのものやその抽出物をそのまま食品等へ配合したのでは、その独特の味と香りが障害となる。   Here, the off-flavor and off-flavor refers to a burnt odor and bitterness derived from roasted coffee beans, an egg flavor and a blue odor derived from raw coffee beans, and the like. Roasted coffee has a unique burning odor and bitterness, and its taste is high, but when blending roasted coffee beans themselves or their extracts into other foods, the taste and aroma are uncomfortable. This is not preferable depending on the type of food. Moreover, since green coffee beans have a peculiar taste and blue odor, when the green coffee beans themselves or their extracts are blended into foods and the like as they are, their unique taste and aroma are an obstacle.

If necessary, the recovered solid part is preferably washed with a liquid. The liquid to be washed is preferably a water-miscible organic solvent (B) or a mixture of the water-miscible organic solvent (B) and water (C) used for the contact treatment from the viewpoint of improving the recovery rate of chlorogenic acid.

回収された固形部はそれ自体異味・異臭が低減されており、その固形部から抽出して得られるクロロゲン酸類含有物は、クロロゲン酸類を高濃度で含有し、かつ異味・異臭が低減されている。クロロゲン酸類含有物の製造方法は、水または水と水混和性有機溶媒との混合物等により、カラム抽出、撹拌抽出等の方法により前記固形部から抽出することができる。水混和性有機溶媒と水との混合物を用いる場合には、水混和性有機溶媒/水の質量比が70/30未満であることが好ましい。抽出の際、水または水と水混和性有機溶媒との混合物等にあらかじめアスコルビン酸ナトリウム等の有機酸または有機酸塩類を添加しても良い。抽出方法としては、水または水と水混和性有機溶媒との混合物等に前記回収された固形部を入れ、加熱・撹拌し、抽出液を回収する方法や(バッチ法)、前記回収された固形部を充填したカラムに高温・加圧条件下で水または水と水混和性有機溶媒との混合物等を通液させて抽出する方法(カラム法)等が挙げられる。また、煮沸脱気や窒素ガス等の不活性ガスを通気して溶存酸素を除去しつつ、いわゆる非酸化的雰囲気下で抽出する方法を併用してもよい。その抽出物は、クロロゲン酸濃度を高めるために蒸発濃縮等してペースト状としたり、噴霧乾燥、凍結乾燥等して粉末状としてもよい。   The recovered solid part itself has a reduced taste and odor, and the chlorogenic acid-containing product obtained by extraction from the solid part contains a high concentration of chlorogenic acids and has a reduced taste and odor. . The method for producing a chlorogenic acid-containing material can be extracted from the solid part by a method such as column extraction or stirring extraction with water or a mixture of water and a water-miscible organic solvent. When a mixture of a water-miscible organic solvent and water is used, the mass ratio of the water-miscible organic solvent / water is preferably less than 70/30. At the time of extraction, an organic acid or an organic acid salt such as sodium ascorbate may be added in advance to water or a mixture of water and a water-miscible organic solvent. As an extraction method, the recovered solid part is put in water or a mixture of water and a water-miscible organic solvent, and the recovered solid is heated and stirred, and the extract is recovered (batch method). For example, a method (column method) in which water or a mixture of water and a water-miscible organic solvent is passed through a column packed with a part under high temperature and pressure conditions, and the like. Moreover, you may use together the method of extracting in so-called non-oxidative atmosphere, ventilating inert gas, such as boiling deaeration and nitrogen gas, and removing dissolved oxygen. The extract may be made into a paste by evaporating and concentrating to increase the chlorogenic acid concentration, or powdered by spray drying or freeze drying.
