Description

本発明は、チーズ及びその製造方法に関する。詳しくは、ヤマブシタケ菌糸体を含有するナチュラルチーズ及びその製造方法に関する。   The present invention relates to cheese and a method for producing the cheese. Specifically, the present invention relates to natural cheese containing Yamabushitake mycelium and a method for producing the same.

乳製品の需要の高まりから、チーズの消費量は増加の傾向にある。昨今の乳の供給困難性の問題と同様に、乳からカードと称される固形物を形成させるために添加される凝乳酵素のレンネットの供給についても慢性的な供給不足から、代用凝乳酵素の研究、開発が進められてきた。その代表例として大腸菌を遺伝子操作して代用凝乳酵素を生産させる方法があるが、消費者の天然物由来や自然物由来志向の観点から遺伝子操作によらない方法が模索されてきた。   Due to increasing demand for dairy products, consumption of cheese is on the rise. Similar to the problem of milk supply difficulties in recent years, the supply of curdling enzyme rennet added to form solids called curd from milk is also a chronic shortage of supply, and substitute milk curd Enzyme research and development have been promoted. As a representative example, there is a method of genetically manipulating E. coli to produce a milk-clotting enzyme. However, methods that do not depend on genetic manipulation have been sought from the viewpoint of consumer natural product-derived or natural product-derived orientation.

そこで、レンネットに代わる凝乳酵素として、Paenibacillus sp.由来の凝乳酵素が提案されている(特許文献1)。   Therefore, a milk-clotting enzyme derived from Paenibacillus sp. Has been proposed as a milk-clotting enzyme that can replace rennet (Patent Document 1).

一般に食用とされている原材料から得られる凝乳酵素を用いてチーズを作製し、同時にチーズに良好な食感を与え、さらに添加物を添加せずに加工工程を増やすことなく、うま味成分であるアミノ酸の含有量を向上させる技術はこれまでになかった。   It is a umami ingredient that makes cheese using curdling enzymes obtained from raw materials that are generally considered edible, and at the same time gives a good texture to the cheese, and without adding processing steps without adding additives. There has never been a technique for improving the amino acid content.

Evaluation 1
Table 1 shows a comparison result of enzyme activity between strains of Yamabushitake mushroom-derived milk-clotting enzyme solution. For the Yamabushitake mycelium, NBRC100328, MAFF420247, MAFF430233, MAFF430234, and MAFF435060 were compared for activity measurement and protein quantification. For the protease activity, the reaction rate at which casein was hydrolyzed was evaluated by the amount of tyrosine produced. The curdling enzyme activity was evaluated by the Soxhlet method after measuring the time when card particles started to form from casein by enzymatic reaction. The ratio (coagulant enzyme activity / protease activity) is the curdase enzyme activity divided by the protease activity. The protein concentration is determined from a calibration curve using bovine serum albumin as a standard protein by a dye binding method. The specific activity of protease activity is protease activity per 1 mg of protein. The specific activity of the curdling enzyme activity means the curdling enzyme activity per 1 mg of protein.

Antibacterial activity is strong against Aspergillus niger, Penicillium caseicolum, Escherichia coli and Candida albicans, and weak against Bacillus subtilis, Aspergillus oryzae, Penicillium roqueforti and Saccharomyces cerevisiae. Antibacterial activity was not observed in the curdling enzyme itself.

ヤマブシタケMAFF435060株由来の凝乳酵素を用いて作製したチーズには熟成中雑菌繁殖が全く認められない一方、MAFF435060株以外のヤマブシタケの凝乳酵素及びレンネットを用いて作製されるチーズは熟成中雑菌繁殖が認められた。Penicillium caseicolum NBRC5849株及びPenicillium roqueforti NBRC5459株に対して、ヤマブシタケMAFF435060株由来の凝乳酵素を用いたチーズには抗菌性が認められた。しかし凝乳酵素自体には抗菌性は認められなかった。   Cheese prepared using the curdling enzyme derived from Yamabushitake MAFF435060 strain does not show any breeding of germs during ripening, while cheese made using the curdling enzyme of Yamabushitake and rennet other than MAFF435060 Breeding was observed. Antibacterial activity was observed in cheese using the curdling enzyme derived from Yamabushitake MAFF435060 strain against Penicillium caseicolum NBRC5849 strain and Penicillium roqueforti NBRC5459 strain. However, the curdling enzyme itself did not show antibacterial activity.

チーズ熟成開始から0、15、30、45、60日後にチーズサンプルを採取し抗菌活性を測定した。抗菌活性はチーズサンプルの周囲のハロの大きさを測定することで評価した。   Cheese samples were collected 0, 15, 30, 45, and 60 days after the start of cheese ripening to measure antibacterial activity. Antibacterial activity was evaluated by measuring the size of the halo around the cheese sample.

MAFF435060株由来の凝乳酵素を用いて作製したチーズにおける熟成時間が抗菌性に及ぼす影響を検討すると、0日目のチーズには抗菌性がなかったため、カード自体には抗菌性はなかった。一方、熟成15日後からチーズに抗菌性が見いだされ、それ以後も抗菌性が維持された。ハロの大きさには30日以後は変化がなかった。   Examination of the effect of ripening time on antibacterial properties in cheese made using the milk-clotting enzyme derived from MAFF435060 strain showed that the curd itself was not antibacterial because the cheese on day 0 had no antibacterial properties. On the other hand, the antibacterial property was found in cheese after 15 days of ripening, and the antibacterial property was maintained thereafter. The size of the halo did not change after 30 days.

G 'storage elastic modulus (elastic term) and G''loss elastic modulus (viscous term) were measured using MCR 302 made by Rheometer Anton paar. The sample was sliced thinly and sandwiched between two flat disks (radius 25 mm) with a gap of 2 mm, and the sample surface was coated with silicone oil to prevent moisture evaporation. Set the sample in the rheometer, gradually decrease the temperature from 50 ℃ to 5 ℃ (2 ℃ / min), and measure G 'storage elastic modulus (elastic term) and G''loss elastic modulus (viscous term) during that time did. The angular frequency of the sample was once per second, and the strain amount was 0.1%.

市販レンネットでのチーズカード(コントロール)とヤマブシタケ酵素でのチーズカードの物性比較は以下のサンプルにより行った。酵素と溶媒との組合わせが弾性率に影響しないよう、ヤマブシタケから凝乳酵素を抽出した際と同じバッファー0.05M McIlvaine buffer (pH 6.0) を用意し、以下の4種類の比較サンプルにより評価した。

Comparison of physical properties of cheese curd with commercially available rennet (control) and cheese curd with Yamabushitake enzyme was performed by the following samples. In order to prevent the combination of the enzyme and the solvent from affecting the elastic modulus, 0.05M McIlvaine buffer (pH 6.0) was prepared in the same manner as when milk-clotting enzyme was extracted from Yamabushitake, and the following four types of comparative samples were evaluated.

図4、図5に示されているように、市販レンネットとヤマブシタケ酵素ではヤマブシタケカードの粘弾性が低く(G’、 G’’が低い)柔らかいカードとなった。なお、抽出溶媒の差は無かった。損失弾性率/貯蔵弾性率比(G’’/G’)はヤマブシタケカードが市販レンネットカードに比べて高く、損失弾性率の寄与が高い結果となった。カードは、市販レンネットカードと比べ、柔らかく、よりなめらかな食感を呈した。これは抽出溶媒の影響を受けたものではなく、酵素液によるものであると考えられる。   As shown in FIGS. 4 and 5, the commercial rennet and the Yamabushitake enzyme were soft cards with low viscoelasticity (G ′ and G ″ were low). There was no difference in the extraction solvent. The loss elastic modulus / storage elastic modulus ratio (G ″ / G ′) was higher for Yamabushitake cards than commercial rennet cards, and the loss elastic modulus contributed greatly. The card was softer and smoother than the commercial rennet card. This is not influenced by the extraction solvent, but is considered to be due to the enzyme solution.

Comparison of physical properties of cheese curd with commercially available rennet, cheese curd with Yamabushitake enzyme, and card with mycelia was performed by the following four types of comparative samples.
(4 types of comparison samples)
Cheese curd with Yamabushitake enzyme with curd Yamabushitake enzyme with curd mycelia with commercial rennet with curd mycelium with commercial rennet

図6、図7に示されているとおり、市販レンネットのみで作製したものが最も固く、G’、 G’’ともに最も高くなった。ヤマブシタケ酵素で作製したカードは市販レンネットを用いたカードよりもG’、 G’’粘弾性が低いため、より柔らかいカードであることが明らかになった。損失弾性率/貯蔵弾性率比(G’’/G’)はヤマブシタケカードが市販レンネットカードと比べて高く、損失弾性率の寄与が高いことが明らかとなった。ヤマブシタケカードは、市販レンネットカードと比べ、柔らかく、よりなめらかな食感を呈した。   As shown in FIG. 6 and FIG. 7, the one made only with the commercial rennet was the hardest, and both G ′ and G ″ were the highest. The card made with Yamabushitake enzyme was found to be a softer card because it has lower G 'and G "viscoelasticity than a card using a commercial rennet. The loss elastic modulus / storage elastic modulus ratio (G ″ / G ′) was higher for Yamabushitake cards than commercial rennet cards, and it was revealed that the contribution of loss elastic modulus was high. The Yamabushitake card was softer and smoother than the commercial rennet card.

菌糸体を加えたカードは市販レンネットカード、ヤマブシタケカードともに、菌糸体を加えないカードと比べてG’、 G’’ともに低く、菌糸体により、柔らかくなった。ヤマブシタケカード、市販レンネットカードの両方で、菌糸体を加える事によりG’’/G’が低くなり、貯蔵弾性率の寄与は高まった。菌糸体は細かい繊維であるため、カード中で抵抗となりコンクリートに鉄筋を入れる様な剛性上昇効果の働きをしていると考えられる。ヤマブシタケ酵素と菌糸体は、それぞれカードに対して、カードを柔らかくする方向に働くことが明らかになった。さらに、菌糸体は弾性の寄与を高める働きがあることが明らかになった。これらの使用量を調節することにより、自由に食感を調製でき、多様な食感を持つチーズの生産が可能である。   Both the commercially available Rennet card and Yamabushitake card were low in both G ′ and G ″, and softened with the mycelium. In both Yamabushitake cards and commercial rennet cards, the addition of mycelia lowered G ″ / G ′, and the contribution of storage modulus increased. Since the mycelium is a fine fiber, it is considered that it works as an effect of increasing rigidity, such as resistance in the card and insertion of rebar into the concrete. It became clear that Yamabushitake enzyme and mycelium act to soften the card, respectively. Furthermore, it was revealed that the mycelium has a function to increase the contribution of elasticity. By adjusting the amount used, the texture can be freely adjusted, and cheeses with various textures can be produced.

このことから、ヤマブシタケ酵素カードは市販レンネットカードと比べ、柔らかくなり(G’、 G’’が低くなる)、損失弾性率G’’の寄与が大きい(柔らかく滑らかな食感)。さらに、菌糸体を入れることで、柔らかくなる(G’、 G’’が低くなる)が貯蔵弾性率の寄与は高まる(柔らかくしっかりとした食感)ことがわかる。   Therefore, the Yamabushitake enzyme card becomes softer (G ′ and G ″ are lower) and the contribution of loss elastic modulus G ″ is larger (soft and smooth texture) than commercial rennet cards. Furthermore, it can be seen that the mycelium is softened (G ′ and G ″ are lowered), but the contribution of the storage elastic modulus is increased (soft and firm texture).

ヤマブシタケ酵素は、低温殺菌牛乳のみならず、高温殺菌牛乳でも凝乳することや、チーズの食味の違いなどから凝乳機構が市販レンネットとは違う独特のものである可能性が考えられた。それを明らかにするため、ホエイのHPLC分析を行った。牛乳中にはカゼインはミセルとして存在している。レンネットの凝乳機構はそのミセルの表面に存在するカッパーカゼインの一部を切断することにより親水部を遊離させ、ミセル表面を疎水性にさせることによる疎水結合で凝乳させるとされている。その際に遊離するグリコマクロペプチド(GMP)がホエイに存在するか否かでヤマブシタケ酵素と市販レンネットで差があるかを確認する。
Evaluation 5
Yamabushitake enzyme may be unique not only in pasteurized milk but also in pasteurized milk, and the curdling mechanism is different from commercial rennets due to differences in cheese taste. In order to clarify it, HPLC analysis of whey was conducted. Casein exists as micelles in milk. Rennet's curding mechanism is said to cleave part of the kappa casein present on the surface of the micelle to release the hydrophilic part and to curd up with a hydrophobic bond by making the micelle surface hydrophobic. Whether there is a difference between the Yamabushitake enzyme and the commercial rennet based on whether or not the glycomacropeptide (GMP) released at that time is present in the whey.

市販レンネットのホエイにはGMPが存在していたが、ヤマブシタケ酵素のホエイにはGMPが存在していないことが明らかになった。このことからヤマブシタケ酵素は市販レンネットと違う凝乳機構を持っている、もしくはヤマブシタケ酵素によって遊離したGMPがヤマブシタケの別の酵素によって分解されてしまっているかのどちらかであると推測される。   GMP was present in commercial wrennet whey, but GMP was not present in Yamabushitake enzyme whey. From this, it is speculated that the Yamabushitake enzyme has a different curdling mechanism from the commercial rennet, or that GMP released by the Yamabushitake enzyme has been degraded by another enzyme of Yamabushitake.

この推論を明らかにするため、ヤマブシタケ酵素と標準試薬のGMPとを反応させ、サンプルを経時変化で回収しHPLCを行った。反応液は0、1、2、5、10、20、30、60分で回収しHPLC分析した。図8にはその結果を示す。これによると、反応0分、60分後の分析結果のいずれにおいてもGMPを示すピークは現れた。GMP濃度を0〜60分のピーク面積から求める。GMPのリテンションタイム(RT)はRT4.553〜6.045に検出されるピークと考えられるが、ヤマブシタケ酵素はRT6.0付近に分解物と思われるピークが一部重なることから、RT4.55でのピークをGMPとして濃度を求めた。GMPの濃度は減少しておらず、HPLCで分かる範囲ではGMPを分解していないことがわかった。   To clarify this reasoning, Yamabushitake enzyme was reacted with GMP, which is a standard reagent, and samples were collected over time and subjected to HPLC. The reaction solutions were collected at 0, 1, 2, 5, 10, 20, 30, 60 minutes and analyzed by HPLC. FIG. 8 shows the result. According to this, a peak indicating GMP appeared in both the analysis results after 0 minutes and 60 minutes after the reaction. The GMP concentration is determined from the peak area of 0-60 minutes. The retention time (RT) of GMP is considered to be a peak detected at RT4.553 to 6.045, but the Yamabushitake enzyme has a peak at RT4.55 because a peak that seems to be a degradation product overlaps around RT6.0. The concentration was determined as GMP. The concentration of GMP did not decrease, and it was found that GMP was not degraded within the range known by HPLC.

ヤマブシタケ酵素はカッパーカゼインからGMPを遊離しない凝乳機構であり、レンネットとは異なった凝乳機構であると考えられた。今までに発見されている凝乳酵素である微生物レンネットはウシ由来のレンネットと同様の機構で凝乳させているため、ヤマブシタケ酵素は凝乳酵素として新規の凝乳機構を持つ酵素であることが明らかである。凝乳機構はカゼインミセル表面におけるカッパーカゼインのGMPの糖鎖部分だけを切断し、GMPのペプチド部分は切断せずにカゼインミセルのほとんどを疎水性にする機構ではないかと推察される。この凝乳機構の場合、ペプチド部分がホエイに流れ出ないため、よりタンパク量が多いチーズ等の作製が期待できる。   Yamabushitake enzyme is a curdling mechanism that does not release GMP from kappa casein and is considered to be a curdling mechanism different from rennet. The microbial rennet, a curdling enzyme that has been discovered so far, is coagulated by a mechanism similar to that of bovine rennet, so the Yamabushitake enzyme is an enzyme with a novel curdling mechanism as a curdling enzyme. It is clear. It is inferred that the curdling mechanism is a mechanism that cleaves only the GMP sugar chain part of kappa casein on the surface of casein micelles and makes most of the casein micelles hydrophobic without cleaving the peptide part of GMP. In the case of this curdling mechanism, since the peptide portion does not flow out into the whey, production of cheese or the like having a higher protein content can be expected.

Measurement of free amino acid content in cheese is as follows. Distilled water at 60 ° C. was added to 1 g of cheese and homogenized. The homogenate was placed in a 10 ml volumetric flask and the volume was adjusted. Take 0.5 ml in a microtube, add 5% TCA solution and mix. After centrifuging the mixture, n-hexane was added to the supernatant and mixed. The aqueous layer was collected and filtered through a 0.2 μm filter to obtain a measurement sample. The sample solution was diluted 2-fold with 0.02M HCl solution and measured with an amino acid analyzer.

ヤマブシタケMAFF435060株由来の酵素と菌糸体を用いたチーズに含まれるアミノ酸含有量を分析した結果を表4に示す。測定試料はレンネットのみ、レンネットとヤマブシタケMAFF435060株菌糸体、ヤマブシタケMAFF435060株由来の酵素のみ、及びヤマブシタケMAFF435060株由来酵素とヤマブシタケMAFF435060株菌糸体を用いて製造したカードを加塩後、13℃で一か月間熟成したナチュラルチーズの4種類について検討した。   Table 4 shows the results of analyzing the amino acid content contained in cheese using the enzyme and mycelium derived from Yamabushitake MAFF435060 strain. The sample to be measured was Rennet only, Rennet and Yamabushitake MAFF435060 strain mycelium, Yamabushitake MAFF435060 strain-only enzyme, and Yamabushitake MAFF435060 strain-derived enzyme and Yamabushitake MAFF435060 strain mycelium were salted and mixed at 13 ° C. Four types of natural cheese ripened for months were examined.

レンネットのみ及びヤマブシタケ菌糸体由来酵素のみで作製したチーズはアミノ酸量が少なく、レンネットのみのものが最も低かった。酵素のみのチーズに比べて、菌糸体を含むチーズはアミノ酸量が増加し、ヤマブシタケ菌糸体由来酵素と菌糸体を用いたチーズが最も高かった。菌糸体を含むチーズはGlu、 Thr、 Val、 Met、 Ile、 Leu、 Phe、 Lysが多かった。   Cheese prepared with only rennet and Yamabushitake mycelium-derived enzymes had low amino acid content, and rennet-only cheese was the lowest. Compared with enzyme-only cheese, cheese containing mycelium had an increased amino acid content, and cheese using Yamabushitake mycelium-derived enzyme and mycelium was the highest. Many cheeses containing mycelium were Glu, Thr, Val, Met, Ile, Leu, Phe, and Lys.
