- soy sauce is prepared by inoculating and cultivating a mixture containing protein materials such as heat-denatured soybean and starchy materials such as wheat which has been gelatinized by heating and cultivating a seed meal containing koji mold.
- the obtained soy sauce koji is charged into a saline solution, and lactic acid fermentation and ripening are carried out to obtain soy sauce moromi mash, and then the obtained soy sauce moromi mash is yeast fermented and ripened to obtain ripening moromi mash, The resulting ripened moromi mash is subjected to a pressing treatment and a filtration treatment to obtain a raw soy sauce and then produced by burning the resulting raw soy sauce.
- soy sauce it is carried out continuously until the ripening taste is obtained from the soy sauce koji. That is, yeast fermentation etc. are performed by adding yeast etc. to soy sauce moromi mash obtained by lactic acid fermentation etc. from soy sauce koji.
- yeast fermentation is incorporated as part of the process in the above-described conventional soy sauce manufacturing method. Yeast fermentation is carried out by adding yeast to a fermentation stock solution for several weeks to several months.
- soy sauce tastes like soy sauce by containing 4-hydroxy-2 (or 5) -ethyl-5 (or 2) -methyl-3 (2H) -furanone (homofuraneol; HEMF) etc. It is lacking in the gorgeousness of the scent.
- soy sauce which has a fruity smell
- soy sauce is manufactured by mixing fruits, wine, etc., and its flavor is completely different from soy sauce.
- Patent Document 3 describes that by externally adding methyl fatty acid such as ethyl 2-methylbutanoate to soy sauce, a soy sauce-like seasoning having a fruity aroma can be obtained.
- amino acids in soy sauce include glutamic acid, glycine, lysine, alanine, aspartic acid and the like, among which a large amount of glutamic acid is contained.
- Glutamate and other amino acids are nitrogen compounds that bring umami to soy sauce. Therefore, the content of nitrogen compounds, that is, the total nitrogen content, is used as an indicator for the umami of soy sauce.
- amino acids in soy sauce are produced by the proteins contained in the raw material soybeans and wheat under the action of bacillus enzymes (proteases, peptidases, glutaminases, etc.).
- Re-charged soy sauce is produced by charging soy sauce koji into raw soy sauce and carrying out a koji making process using fermented soy sauce as feed water, and then fermenting and ripening with yeast.

本発明の一態様の調味料用原液は、還元糖の含有量及びエタノールの含有量を所定の量に調整したものであることにより、簡便な酵母発酵の用に供され得る。その結果として、本発明の一態様の調味料用原液を用いれば、安定した品質の酵母発酵物としての調味料が得られ得る。
なお、上記で得られた醤油諸味の液汁若しくは調味料用原液について、吸着樹脂を用いた脱色処理に供すると、遊離脂肪酸やアミノ酸などが吸着されることから、醤油諸味の液汁若しくは調味料用原液を吸着樹脂を用いた脱色処理に供することは好ましくない。
(1-1)還元糖の含有量:4.5~30wt%
(2-1)エタノールの含有量:0~1.5wt%

本発明の一態様の木片は、圧縮加工がされており、かつ、特定の体積を有することを特徴とする。本発明の技術的範囲はいかなる理論や推測によって拘泥されるものではないが、本発明の一態様の木片は、圧縮加工された木材からなるものであることにより、木質組織が壊れて、組織内部の気体が抜けやすく液体が入り込みやすくなり、さらに比重が高まることにより、木材でありながら液体中で沈降することができるものである可能性がある。また、液体中に沈降した本発明の一態様の木片に気体(泡)が触れると、木片の組織内部で気液交換が発生して、気体を取り込んで浮力が大きくなり、浮上するようになる。さらに、酵母発酵が進行することによって、アルコールが生成し、調味料用原液の密度が下がることも木片が浮上する要因の一つと考えられる。ただし、このとき、体積(質量)が大きいと、木片の浮上が妨げられることから、本発明の一態様の木片は、気体を取り込んだ際に浮上できる程度の体積を有する。これに対して、圧縮加工をしていない天然木材に由来する木片は、比重が低いために液体中に沈降しないものが多い。沈降するものであっても、木片に気体が付着しにくいこと、組織内部に空気が取り込まれにくいことなどの理由によって、気体を取り込まずに沈降したままの状態を保つため、いずれにしても発酵の指標としてふさわしいものとはいえない。
