Description

すなわち、本発明は、以下の［１］〜［６］を提供するものである。
［１］発酵乳の原料に乳酸桿菌及び乳酸球菌を添加し発酵させて、発酵乳を得る発酵工程と、該発酵乳に酸素を供給して、溶存酸素量が増大した発酵乳を得る酸素供給工程とを含むことを特徴とする発酵乳の製造方法。
［２］上記乳酸桿菌が、ラクトバチルス・ブルガリカスであり、かつ、上記乳酸球菌がストレプトコッカス・サーモフィルスである上記［１］に記載の発酵乳の製造方法。
［３］上記酸素供給工程における酸素の供給の終了時から２５日間経過後の時点までの１０℃の温度下での酸度の増大の幅が、０．２０％以下である上記［１］又は［２］に記載の発酵乳の製造方法。
［４］上記酸素供給工程における酸素の供給の終了時において、上記発酵乳中の溶存酸素濃度が１２ｐｐｍ以上である上記［１］〜［３］のいずれかに記載の発酵乳の製造方法。
［５］上記発酵乳が前発酵型の発酵乳である上記［１］〜［４］のいずれかに記載の発酵乳の製造方法。
［６］上記前発酵型の発酵乳がソフトヨーグルトまたはドリンクヨーグルトである上記［５］に記載の発酵乳の製造方法。 That is, the present invention provides the following [1] to [ 6 ].
[1] A fermentation process in which lactobacilli and lactobacilli are added to the raw material of fermented milk and fermented to obtain fermented milk, and oxygen supply to obtain fermented milk with an increased amount of dissolved oxygen by supplying oxygen to the fermented milk A process for producing fermented milk, comprising a step.
[2] The method for producing fermented milk according to [1], wherein the Lactobacillus is Lactobacillus bulgaricus, and the Lactococcus is Streptococcus thermophilus.
[3] The [1] or [ [2] The method for producing fermented milk according to [2].
[4] The method for producing fermented milk according to any one of [1] to [3], wherein the dissolved oxygen concentration in the fermented milk is 12 ppm or more at the end of the supply of oxygen in the oxygen supplying step.
[5] The method for producing fermented milk according to any one of [1] to [4], wherein the fermented milk is pre-fermented fermented milk.
[6] The method for producing fermented milk according to [5] above, wherein the pre-fermented fermented milk is soft yogurt or drink yogurt.
