Description
本発明は、酒粕発酵エキスを用いた風味改良剤およびその製造方法に関する。 The present invention relates to a flavor improver using a fermented sake lees extract and a method for producing the same.
酒粕中には、米、米麹、酵母に由来した成分である各種アミノ酸類、ビタミン類、有機酸類、タンパク質、各種糖類などの多くの栄養成分、旨味成分のごとき有効成分が含まれているにもかかわらず、現在、奈良漬などの漬物、甘酒、粕取焼酎などの食品素材として使用されている程度であり、これらの有効成分について、十分な利用がなされているとは言い難い。 Sake lees contain various nutritional components such as various amino acids, vitamins, organic acids, proteins, various sugars, and other active ingredients such as umami components derived from rice, rice bran and yeast. Nevertheless, it is currently only used as a food material such as pickles such as Nara-zuke, amazake, and shochu shochu, and it is difficult to say that these active ingredients are fully utilized.
酒粕から調味液あるいは調味料を調製する伝統的な方法として、例えば清酒粕に水を加えて高温長期間、例えば約60℃で15日間程度放置した後、圧搾ろ過を行い、ろ液をアルコール、糖類、食塩などで味を調整して調味液とする方法がある。しかしながら、得られるろ液は濃い褐色および焦げ臭を有するため、その除去に活性炭処理等が必要となる。また特許文献1には、清酒粕を用いて粕取焼酎を製造する際の副産物にプロテアーゼおよびアミラーゼを作用させ、さらに調味のためにアルコール、糖類、食塩などで味を調整した調味液が開示されている。しかしながら、この調味液はアミノ酸などの旨味が十分ではない。 As a traditional method for preparing a seasoning liquid or seasoning from sake lees, for example, water is added to sake lees lees and left at high temperature for a long period of time, for example, about 60 ° C. for about 15 days, followed by squeezing and filtering the filtrate with alcohol, There is a method of adjusting the taste with sugars, salt, etc. to make a seasoning liquid. However, since the obtained filtrate has a dark brown color and a burning odor, activated carbon treatment or the like is required for its removal. Further, Patent Document 1 discloses a seasoning liquid in which protease and amylase are allowed to act on by-products when producing kojiri shochu using sake lees and the taste is adjusted with alcohol, sugar, salt, etc. for seasoning. ing. However, this seasoning liquid does not have sufficient umami such as amino acids.
特許文献2には、酒粕にプロテアーゼ、溶菌酵素、ヌクレアーゼ及びデアミナーゼからなる群から選択される2種以上の酵素を使用して調製した調味液が開示されている。しかしながら、この文献は、実質的に麹自己消化液として麹を長期に熟成させたものを大量に添加することを必須としており、得られる調味液は甘味が強く、現実的には調味液としての利用には向かないものである。また、この文献にはアミラーゼでの処理は開示されていない。 Patent Document 2 discloses a seasoning liquid prepared using two or more kinds of enzymes selected from the group consisting of protease, lytic enzyme, nuclease and deaminase in sake lees. However, this document essentially requires that a large amount of cocoon ripened for a long time as a cocoon self-digestion solution is essential, and the resulting seasoning solution has a strong sweetness, and in reality, as a seasoning solution It is not suitable for use. In addition, this document does not disclose treatment with amylase.
特許文献3には、酒粕、ソース残渣、醤油粕、キノコ類の石突といった副産物を加熱殺菌後、pH調整を行い、酵母などの微生物と酵素を加え30〜50度で発酵させる調味料の製造方法が開示されている。また、特許文献4には、乾燥固形分当たり総窒素含量が8.5重量%以上、かつ全糖含量が5重量%以上45重量%以下である酒粕を、自己消化分解もしくは酵素反応分解する酒粕酵母エキスの製造方法が開示されている。しかしながら、これらを実際に調味料として食品等へ添加した際の効果は十分に報告されていない。また、どちらの文献も、アミラーゼ等の酵素を加える前に加熱により酵素を失活させる工程を含む。 Patent Document 3 discloses a method for producing a seasoning in which by-products such as sake lees, sauce residues, soy sauce lees, and mushrooms are heat-sterilized, pH is adjusted, and microorganisms such as yeast and enzymes are added and fermented at 30 to 50 degrees Is disclosed. Patent Document 4 discloses a sake lees that have a total nitrogen content of not less than 8.5% by weight and a total sugar content of not less than 5% by weight and not more than 45% by weight based on the dry solid content, and are subjected to self-digestion decomposition or enzymatic reaction decomposition. A method for producing a yeast extract is disclosed. However, the effect at the time of actually adding these as a seasoning to food etc. is not fully reported. In addition, both documents include a step of inactivating the enzyme by heating before adding an enzyme such as amylase.
特許文献5および6には、酒粕にデンプン分解酵素およびタンパク質分解酵素を加え、固液分離して、固体成分(引用文献5)および液体成分(引用文献6)を使用する、多様な生理機能を有する素材が開示されている。しかしながら、これら文献には生理機能を期待して食品に添加することの開示はあるものの、食品の風味を改良することについての開示はない。 Patent Documents 5 and 6 include various physiological functions in which starch-degrading enzyme and proteolytic enzyme are added to sake lees, solid-liquid separation is performed, and solid components (Cited document 5) and liquid components (Cited document 6) are used. The material which has is disclosed. However, although these documents disclose the addition to foods with the expectation of physiological functions, there is no disclosure about improving the flavor of foods.
醸造副産物である酒粕は、依然としてさらなる利用法の開発が必要であり、またこれを利用した風味の良い調味料素材が求められている。 Sake lees, a by-product of brewing, still require further development of usage, and there is a need for a flavoring seasoning material using this.

To this, 6.0 g (1.0 × 10 10 pieces / g) of solid yeast, 0.3 g of amylase agent (Gluc 100: manufactured by Amano Enzyme) (1/2000 amount of sake lees), and protease agent (Orientase 20A: HB eye) 0.75 g (1/800 amount of sake lees) was added and fermented at a constant temperature of 25 ° C. for 3 days. After completion of the fermentation, the mixture was sterilized at a temperature of 70 ° C., and 1,094 mL of sake lees fermented extract was obtained by centrifugation.
続いて、この発酵エキスをスプレードライヤー(SB39型、プリス製)により粉末化した。酒粕発酵エキスの固形分と賦形剤の比率が7:3になるように腑形剤を添加し粉末化することで、酒粕発酵エキス800gから55gの酒粕発酵エキス粉末を得ることができた。よって、酒粕発酵エキス1,094mLを全て粉末化した場合、76gの粉末を得ることができる。 Subsequently, the fermented extract was pulverized with a spray dryer (SB39 type, manufactured by Pris). By adding a koji mold so that the ratio of the solid content of the sake lees fermented extract to the excipient was 7: 3, and pulverizing it, 800 g to 55 g of sake lees fermented extract powder could be obtained. Therefore, 76 g of powder can be obtained when all 1,094 mL of sake lees fermented extract is powdered.
また、特許文献3において、酒粕を50〜90℃で加熱し、残存する酵素活性等を失活させてから、微生物および酵素を添加することを特徴とした調味料が報告されている。そこで、再発酵する前に90℃達温で加熱した液化酒粕を用いて、同様の粉末を調製した。 Patent Document 3 reports a seasoning characterized by heating a sake cake at 50 to 90 ° C. to deactivate the remaining enzyme activity and the like, and then adding microorganisms and enzymes. Then, the same powder was prepared using the liquefied sake lees heated at 90 degreeC temperature before re-fermenting.

アミノ酸組成分析の結果、液化酒粕を加熱殺菌せずに再発酵することにより、加熱殺菌した場合と比較して、遊離アミノ酸含量が約2倍多い粉末が得られることが示された。特に旨味への寄与が大きいと思われるグルタミン酸、アスパラギン酸に関しては、加熱殺菌した場合と比較してそれぞれ2.4倍、3.1倍多かった。有機酸含量に関しては、大きな差はなかった。 As a result of amino acid composition analysis, it was shown that by re-fermenting the liquefied sake lees without heat sterilization, a powder having about twice as much free amino acid content as that obtained by heat sterilization was obtained. In particular, glutamic acid and aspartic acid, which are thought to have a large contribution to umami, were 2.4 times and 3.1 times as many as those in the case of heat sterilization, respectively. There was no significant difference in terms of organic acid content.
