METHOD FOR PRODUCING FERMENTATION CITRUS FRUIT JUICE PRODUCT

To provide a method for producing a fermentation citrus fruit juice product which treats and ferments a fruit juice obtained by squeezing a citrus fruit such as aroma acid citrus such as citron, miscellaneous fruits such as new summer orange, and Buntan such as Buntan with a fruit skin, can impart a rich fermentation flavor, and can sufficiently feel flavor and aroma of the aroma acid citrus, the miscellaneous fruits and the Buntan.SOLUTION: A method for producing a fermentation citrus fruit juice product includes: a squeezing step (i) of squeezing a fruit of any one citrus of aroma acid citrus, miscellaneous fruits and Buntan with a fruit skin, and taking a fruit juice; a fiber decomposition step (ii) of adding a clarified enzyme to the fruit juice, and releasing an essential oil component while decomposing a fiber; a separation step (iii) of distilling the fiber decomposed fruit juice by microwaves, and extracting and separating a microwave distilled essential oil component-containing extract; a fermentation step (iv) of fermenting a residual fruit juice after separation in the presence of sugar by fermentation yeast, and obtaining residual fruit juice fermentation unrefined liquor; and a mixing step (v) of obtaining a fermentation citrus fruit juice obtained by mixing the microwave distilled essential oil component-containing extract with the unrefined liquor.SELECTED DRAWING: Figure 1 【課題】ゆず等香酸柑橘類や日向夏等の雑柑類やブンタン等の文旦類のような柑橘果実を果皮ごと搾った果汁を処理して発酵させて豊かな発酵風味を付与することができ、発酵させても、これら香酸柑橘類や雑柑類や文旦類の風味・香りが十分に感じられる発酵柑橘果汁製品の製造方法を提供する。【解決手段】発酵柑橘果汁製品の製造方法は、香酸柑橘類と雑柑類と文旦類との何れかの柑橘類の果実を果皮ごと搾って果汁を取る搾汁工程(i)と、前記果汁に清澄化酵素を添加し繊維質分解しつつ精油成分を遊離させる繊維質分解工程(ii)と、その繊維質分解果汁をマイクロ波蒸留してマイクロ波蒸留精油成分含有抽出物を抽出して分離する分離工程(iii)と、その分離後の残果汁を糖分存在下で発酵酵母により発酵させて残果汁発酵もろみを得る発酵工程(iv)と、それに前記マイクロ波蒸留精油成分含有抽出物を配合して混合した発酵柑橘果汁を得る混合工程(v)とを、有する。【選択図】図１
