Description

本発明は、バナナ本来の香味が優れ、バナナの明るい色調を有するバナナピューレに関し、また非常に滑らかな食感と適度な粘性を有し、咀嚼、嚥下困難者用に適し、またユニバーサルデザインフードで規定した、舌でつぶせるゾル又は噛まなくてもよいゾルに相当するバナナピューレに関する。   The present invention relates to a banana puree that has a banana's original flavor and has a bright color of banana, and has a very smooth texture and moderate viscosity, suitable for those who have difficulty chewing and swallowing, and is a universal design food. The present invention relates to a banana puree corresponding to a sol that can be crushed with a tongue or a sol that does not need to be chewed.

一般に、バナナは、剥皮すると果肉が褐変酵素(ポリフェノールオキシダーゼなど)の作用により急速に黒変し、商品価値を損なうことが知られている。
従来その解決法として、フェルラ酸を使用する方法(特許文献1参照)、麹酸とL−アスコルビン酸を併用する方法(特許文献2参照)、食塩水又はL−アスコルビン酸を使用する方法(特許文献3参照)並びに酸、明礬及びポリリン酸塩を使用する方法(特許文献4参照)等が知られている。
しかし、これらの方法はフェルラ酸、麹酸、明礬又はポリリン酸塩などの添加物使用を余儀なくされる問題を有する。また食塩又は酸の使用は、バナナ加工食品のバナナ本来の香味を劣化させる問題を有する。
In general, it is known that when a banana is peeled, the pulp turns rapidly black due to the action of a browning enzyme (such as polyphenol oxidase), thereby impairing the commercial value.
As a conventional solution, a method using ferulic acid (see Patent Document 1), a method using succinic acid and L-ascorbic acid in combination (see Patent Document 2), a method using saline or L-ascorbic acid (Patent) Document 3) and a method using acid, alum and polyphosphate (see Patent Document 4) are known.
However, these methods have the problem of necessitating the use of additives such as ferulic acid, oxalic acid, alum or polyphosphate. Further, the use of salt or acid has a problem of deteriorating the original banana flavor of the processed banana food.

一方、バナナを剥皮することなく、皮付きのままで加熱し、果肉温度を80〜100℃に上昇させて、バナナ果肉に含まれるポリフェノールオキシダーゼやペクチンエステラーゼ等を3〜60秒で失活させ、次いで冷却し、剥皮してバナナ果肉を得、フードミキサーにて破砕するバナナ加工食品の製造法(特許文献5参照)が知られている。
しかしこのバナナ加工法は、皮付きのまま加熱する方法であるため、該加熱によってバナナの果皮が異臭を放ち、この臭いがバナナの果肉にまで移行付着浸透するため、バナナ加工食品はバナナ本来の香味が損なわれる欠点を有する。
On the other hand, without peeling the banana, heat it with the skin, raise the pulp temperature to 80-100 ° C., inactivate polyphenol oxidase, pectinesterase, etc. contained in the banana pulp in 3-60 seconds, Next, a method for producing a banana processed food that is cooled and peeled to obtain banana pulp and crushed with a food mixer (see Patent Document 5) is known.
However, since this banana processing method is a method of heating with the skin peeled, the banana peel gives off a strange odor due to the heating, and this smell migrates and penetrates into the banana flesh. It has the disadvantage that flavor is impaired.

また、バナナ果肉1kgをステンレス製の攪拌機を具備した二重釜に仕込み、これにクエン酸1g、L−アスコルビン酸0.5g、ペクチン2g及び水4mlを混和し、無酸素雰囲気下(真空状態下)で、75〜81℃で8分間高速攪拌して微細化し、バナナピューレを得る方法(特許文献6参照)が知られている。
しかし、このバナナ加工法には、バナナを剥皮した後、果肉を輪切りすることについて記載がなく、また果肉の加熱処理温度が75〜81℃であって、85℃未満の温度を採用するため、黒変化防止効果が充分でなく、明るい色調のバナナ加工食品を得ることができない問題を有する。
In addition, 1 kg of banana pulp was placed in a double kettle equipped with a stainless steel stirrer, and 1 g of citric acid, 0.5 g of L-ascorbic acid, 2 g of pectin and 4 ml of water were mixed in an oxygen-free atmosphere (under vacuum conditions) ), A method of obtaining banana puree by high-speed stirring at 75 to 81 ° C. for 8 minutes (see Patent Document 6) is known.
However, in this banana processing method, after peeling the banana, there is no description about slicing the pulp, and the heat treatment temperature of the pulp is 75 to 81 ° C, and a temperature lower than 85 ° C is adopted. There is a problem that the effect of preventing black change is not sufficient, and a banana processed food with a bright color cannot be obtained.

また、バナナを剥皮し、得られたバナナ果肉をクラッシャーで破砕する際にL−アスコルビン酸溶液を加えて空気による酸化褐変を防ぎ、続くスクリューコンベア内で約85℃に加熱して酵素を失活させ、裏ごし波形0.5mmのパルパーを用い、種子、繊維質を除き、遠心分離してパルプ量を調節し、脱気によりピューレ中の空気を除き褐変を防ぐ、バナナピューレの製造法(非特許文献1参照)が知られている。
しかし、このバナナ加工法もバナナを剥皮した後、果肉を輪切りすることについて記載がない。このようにバナナ果肉を輪切りすることなくそのまま破砕するときは、果肉が速やかに褐変して明るい色調のバナナ加工食品を得ることができない問題を有する。また、バナナ加工食品は、バナナ本来の香味が乏しい欠点を有する。

In addition, when banana is peeled and the resulting banana pulp is crushed with a crusher, an L-ascorbic acid solution is added to prevent oxidative browning by air, and the enzyme is deactivated by heating to about 85 ° C. in the subsequent screw conveyor. A banana puree manufacturing method that uses a pulper with a corrugation of 0.5 mm on the back, removes seeds and fibers, adjusts the amount of pulp by centrifugation, and removes air in the puree by deaeration to prevent browning (non-patented) Document 1) is known.
However, this banana processing method also does not describe that the pulp is cut after peeling the banana. In this way, when the banana pulp is crushed as it is without being cut, there is a problem that the pulp is quickly browned and a banana processed food with a bright color cannot be obtained. In addition, banana processed foods have the disadvantage that the original flavor of bananas is poor.

本発明によれば、バナナ本来の香味が優れ、バナナの明るい色調を有するバナナピューレ及びバナナ加工食品を容易に得ることができる。   ADVANTAGE OF THE INVENTION According to this invention, the banana puree and banana processed food which are excellent in the original flavor of a banana and have the bright color of a banana can be obtained easily.

本発明で原料となるバナナは、その品種や産地に制限はなく、生食用のバナナ及び料理用バナナが挙げられる。生食用バナナとしてはキャベンディッシュ、セニョリータ、ラトンダン、ラカンタン及びモラード等が、また料理用バナナとしては、カルダバ、ツンドク、サバ及びリングキット等が挙げられる。   The banana used as a raw material in the present invention is not limited in its variety and production area, and examples include bananas for raw consumption and bananas for cooking. Examples of raw bananas include cavendish, senorita, latondan, lakantang, and molard, and examples of bananas for cooking include cardava, tundra, mackerel, and a ring kit.

また、本発明における原料バナナは、中央部が黄色で両端が青いもの、全体が黄色で黒斑(シュガースポットとも言う)がないもの、黒斑が出始めたもの(バナナ果皮中黒斑の占有面積が1〜60%のもの)及び全体に黒斑があるもの(同黒斑の占有面積が61%以上のもの)など任意のものが採用可能である。
これらのうち、バナナ追熟加工室内でエチレンガスを導入して追熟したもの、単に保存することによって追熟したもの、又はこれらの追熟によりバナナの果皮に黒い斑点(シュガースポット)が発生したものがより好ましい。そして、特にシュガースポットが出始めたバナナ、すなわちバナナ果皮中黒斑の占有面積が1〜60%のものが最も好ましい。
In addition, the raw material bananas in the present invention are yellow at the center and blue at both ends, are entirely yellow and have no black spots (also called sugar spots), or have started to appear black spots (occupation of black spots in banana peels) Arbitrary ones such as those having an area of 1 to 60% and those having black spots on the entire surface (having an area occupied by the black spots of 61% or more) can be employed.
Of these, those that were ripened by introducing ethylene gas in the banana ripening processing chamber, those that were ripened simply by storage, or black spots (sugar spots) occurred on the banana peels due to these ripening Those are more preferred. In particular, the banana where the sugar spot has started to appear, that is, the occupying area of black spots in the banana peel is most preferably 1 to 60%.

本発明を実施するには、先ず、バナナの果皮を剥皮する。
本発明において、この果皮を剥皮することは極めて重要であって、バナナを剥皮することなく、皮つきのままで加熱するときは、加熱と共にバナナの果皮が一種独特な異臭を放ち、これがバナナの果肉にまで移行して、付着浸透するため、バナナピューレはバナナ本来の香味が損なわれる欠点を有する。
In order to carry out the present invention, first, peel the banana peel.
In the present invention, it is extremely important to peel off the peel, and when the banana peel is heated without being peeled, the banana peel emits a unique odor with heating, which is the fruit of the banana. The banana puree has a drawback that the original flavor of the banana is impaired.

次に、本発明では剥皮して得られるバナナ果肉を輪切りにする。
本発明において、この輪切りすることも重要であって、輪切りすることなく加熱するときは、その後に続いて行われる加熱工程において加熱ムラが起こり、バナナピューレの褐変化を完全に防止することができなくなる。また、バナナ本来の香味が劣化する問題を有する。
Next, in this invention, the banana pulp obtained by peeling is cut into round pieces.
In the present invention, this rounding is also important, and when heating without rounding, uneven heating occurs in the subsequent heating step, and the browning of banana puree can be completely prevented. Disappear. Moreover, there is a problem that the original flavor of the banana deteriorates.

また、この輪切りの方法は、制限はなく、例えば、電動フードカッターや、ナイフ及び包丁等の刃物の使用が挙げられる。
輪切りは、5〜15mmが好ましく、7〜13mmがより好ましく、8〜12mmが最も好ましい。
5mm未満の輪切り(スライス)、粗砕、微塵切りなどでは速やかにバナナ果肉が褐変化するため好ましくない。反対に15mmを越えると加熱ムラが生じるので好ましくない。
Moreover, there is no restriction | limiting in the method of this ring cutting, For example, use of blades, such as an electric food cutter, a knife, and a kitchen knife, is mentioned.
The round cut is preferably 5 to 15 mm, more preferably 7 to 13 mm, and most preferably 8 to 12 mm.
If it is less than 5 mm, it is not preferable because the banana flesh turns brown quickly. On the other hand, if it exceeds 15 mm, heating unevenness occurs, which is not preferable.

また、本発明では輪切りしたバナナを、0.22℃/秒以上の昇温速度で、その中心部を85〜100℃まで、水蒸気、飽和蒸気、過熱水蒸気又は加熱空気等の加熱気体により加熱する。
本発明において、0.22℃/秒以上の昇温速度を採用することも重要であって、この値より少ないとバナナピューレの褐変化を効果的に防止することができない。
また、加熱温度が85℃未満では褐変を完全に防止することができない。反対に100℃を越えるとバナナ本来の香味が損なわれるので好ましくない。
Further, in the present invention, a banana cut into slices is heated at a temperature rising rate of 0.22 ° C./second or more at a central portion up to 85 to 100 ° C. with a heating gas such as water vapor, saturated steam, superheated steam or heated air. .
In the present invention, it is also important to employ a temperature rising rate of 0.22 ° C./second or more. If it is less than this value, the browning of banana puree cannot be effectively prevented.
Moreover, when heating temperature is less than 85 degreeC, browning cannot be prevented completely. On the other hand, if the temperature exceeds 100 ° C., the original flavor of the banana is impaired.

この加熱手段としては加熱気体との接触手段が挙げられ、例えばスチームクッカーや蒸し器等のスチームブランチングなどが挙げられる。二重釜やスコルダー(湯煮機)等による熱水ブランチングによる加熱の場合は、バナナの成分が一部熱水中に溶解流出し、また熱水の一部がバナナ組織に浸透して成分が希釈され、バナナピューレが水っぽい味になるので好ましくない。また、電子レンジ等のマイクロ波による誘電加熱も加熱した際に、バナナ表面が部分加熱されて沸騰してしまうため、好ましくない。
上記加熱気体は、バナナの果肉が水と接触することなく、バナナの果肉を加熱することができるので、水との接触に伴う成分の流出と希釈を防止でき、バナナ本来の香味を損なうことがないので好ましい。
Examples of the heating means include a contact means with a heated gas, and examples thereof include steam blanching such as a steam cooker and a steamer. In the case of heating by hot water blanching using a double kettle or a scorder (boiler), some of the banana components dissolve and flow out into the hot water, and some of the hot water penetrates into the banana tissue. Is diluted, and banana puree has a watery taste. Further, when dielectric heating by microwaves such as a microwave oven is also heated, the banana surface is partially heated and boiled, which is not preferable.
The above heated gas can heat the banana pulp without the banana pulp coming into contact with water, so it can prevent the outflow and dilution of components accompanying the contact with water, and can impair the original flavor of the banana. It is preferable because it is not present.

また、本発明では加熱処理後のバナナにL−アスコルビン酸を添加するが、添加量は0.1〜0.2(w/w)%が好ましく、0.12〜0.18(w/w)%がより好ましく、0.14〜0.16(w/w)%が最も好ましい。
アスコルビン酸が0.1(w/w)%より少ないと、褐変防止効果が充分でなく、製造したバナナピューレの色調が褐色になり、反対に0.2(w/w)%より多いと、バナナピューレの酸味が増して、その香味が悪くなるので好ましくない。
Moreover, in this invention, although L-ascorbic acid is added to the banana after heat processing, 0.1-0.2 (w / w)% is preferable and the addition amount is 0.12-0.18 (w / w). )% Is more preferable, and 0.14 to 0.16 (w / w)% is most preferable.
When ascorbic acid is less than 0.1 (w / w)%, the browning prevention effect is not sufficient, and the color of the produced banana puree becomes brown, and conversely, when it is more than 0.2 (w / w)%, Since the sourness of banana puree increases and the flavor deteriorates, it is not preferable.

加熱処理後のバナナにL−アスコルビン酸を添加した後は、常法により破砕し、バナナピューレを得る。
本発明において得られるバナナピューレは、硬さが、1×10N/m以下が好ましく、500〜2000N/mがより好ましく、800〜1200N/mが最も好ましい。
また粘度は、1.5Pa・s以上が好ましく、5〜30Pa・sがより好ましく、7〜15Pa・sが最も好ましい。
硬さが10000N/mを超えるときは、バナナピューレの固形物が舌で潰せなくなり、また粘度が1.5Pa・s以下であるときは、バナナピューレとして充分な食感を味わえなくなり、咀嚼、嚥下困難者用のバナナ加工食品としては充分に満足することができなくなるので好ましくない。
After adding L-ascorbic acid to the banana after heat processing, it crushes by a conventional method and a banana puree is obtained.
Banana puree obtained in the present invention, hardness of preferably 1 × 10 4 N / m 2 or less, more preferably 500~2000N / m 2, 800~1200N / m 2 is most preferred.
The viscosity is preferably 1.5 Pa · s or more, more preferably 5 to 30 Pa · s, and most preferably 7 to 15 Pa · s.
When the hardness exceeds 10,000 N / m 2 , the solid material of the banana puree can not be crushed by the tongue, and when the viscosity is 1.5 Pa · s or less, the banana puree can not taste a sufficient texture, chewing, Since it becomes impossible to fully satisfy as a banana processed food for persons with difficulty swallowing, it is not preferable.

本発明のバナナピューレは、(1)バナナ果肉を輪切りする手段、(2)加熱気体による急速加熱手段及び(3)アスコルビン酸を添加した後破砕する手段をこの順序で行う(組合せる)ことを最も特徴としており、この特徴を採用することにより、固形物は舌でつぶせる程度に軟らかく、また非常に滑らかな食感と適度な粘性を有し、しかもバナナ本来の香味が優れており、また色調の明るいバナナピューレを容易に得ることができる。本発明のバナナピューレは、硬さが1×10N/m以下であり、粘度が1.5Pa・s以上、色調L値が62.0以上であり、咀嚼、嚥下困難者用のバナナ加工食品として好適であり、またユニバーサルデザインフードで規定した、舌でつぶせるゾル又は噛まなくてもよいゾルに相当するバナナピューレとして好適に利用可能である。 The banana puree of the present invention performs (combines) (1) means for cutting banana flesh, (2) rapid heating means with heated gas, and (3) means for crushing after adding ascorbic acid in this order. By adopting this feature, the solid material is soft enough to be crushed by the tongue, has a very smooth texture and moderate viscosity, and has an excellent banana flavor and color tone. The bright banana puree can be easily obtained. The banana puree of the present invention has a hardness of 1 × 10 4 N / m 2 or less, a viscosity of 1.5 Pa · s or more, a color tone L value of 62.0 or more, and a banana for those who have difficulty chewing or swallowing It is suitable as a processed food, and can be suitably used as a banana puree corresponding to a sol that can be crushed with a tongue or a sol that does not need to be chewed, as defined by a universal design food.

(バナナの熟度の検討)
表1の各熟度にある剥皮したバナナ500gを、厚さ10mmに輪切りにし、スチームブランチャーを用いて、初発の中心温度が約20℃の該バナナ果肉を、その中心温度が300秒間で85℃に達するまで水蒸気加熱した(昇温速度0.22℃/秒)。そして、当該加熱処理したバナナの重量に対して、0.15(w/w)%のL−アスコルビン酸を添加してミキサーで破砕しバナナピューレを作製して、当該バナナピューレの物性(硬さ、粘度)と色調(L値)の測定と官能評価を行った。
その結果を表2に示す。
なお、バナナピューレの物性(硬さ、粘度)と色調(L値)の測定は、以下の方法で行った。
(Investigation of ripeness of banana)
500 g of peeled bananas at each maturity in Table 1 are cut into 10 mm thicknesses, and using a steam blanker, the banana pulp with an initial center temperature of about 20 ° C. is 85% in 300 seconds. Steam heating was performed until the temperature reached 0 ° C. (temperature increase rate 0.22 ° C./second). Then, 0.15 (w / w)% L-ascorbic acid is added to the weight of the heat-treated banana and crushed with a mixer to prepare a banana puree. The physical properties (hardness of the banana puree , Viscosity) and color tone (L value) and sensory evaluation.
The results are shown in Table 2.
The physical properties (hardness, viscosity) and color tone (L value) of banana puree were measured by the following methods.

(1)硬さ
テクスチャーアナライザー(英弘精機社製)を用いて、品温20℃に調整したバナナピューレを直径40mmで高さ15mmの容器に充填し、直径20mmのプランジャーで、圧縮速度10mm/秒、クリアランス5mmの条件で5回測定した。そして当該測定値の最大値と最小値を除いた3回の値の平均をバナナピューレの硬さの測定値とした。尚、熟度3のバナナ果肉の断面の色調L値は69.80であり、他の熟度1、2、4のバナナ果肉断面のL値もほぼ同程度であった。
(1) Hardness Using a texture analyzer (manufactured by Eiko Seiki Co., Ltd.), a banana puree adjusted to a product temperature of 20 ° C. was filled into a container with a diameter of 40 mm and a height of 15 mm, and a plunger with a diameter of 20 mm was used to compress a compression speed of 10 mm / Second, the measurement was performed 5 times under the condition of a clearance of 5 mm. Then, the average of the three values excluding the maximum value and the minimum value of the measurement value was used as the measurement value of the hardness of the banana puree. In addition, the color tone L value of the cross section of the banana pulp of maturity 3 was 69.80, and the L value of the banana pulp cross sections of the other maturities 1, 2, and 4 was almost the same.

(2)粘度
B型回転粘度計(東機産業社製)を用いて、品温20℃に調整したバナナピューレを12rpmでローターを回転させて、2分後の示度を測定した。測定は2回行い、その平均をバナナピューレの粘度の測定値とした。
(2) Viscosity Using a B-type rotational viscometer (manufactured by Toki Sangyo Co., Ltd.), the banana puree adjusted to a product temperature of 20 ° C. was rotated at 12 rpm, and the reading after 2 minutes was measured. The measurement was performed twice, and the average was taken as the measured value of the viscosity of the banana puree.

(3)L値
測色色差計(日本電色工業社製)を用いて、バナナピューレの色調L値を測定した。




(3) L value The color tone L value of the banana puree was measured using a colorimetric color difference meter (manufactured by Nippon Denshoku Industries Co., Ltd.).

表2の結果から、果皮の状態が全体に黒くなった熟度4のバナナは、その果肉が非常に柔らかいため、切断処理やその他の取扱いで、果肉にダメージを受けやすく、製造したババナピューレの色調が若干劣るが、熟度3の果皮にシュガースポットが出始めたバナナを原料にパナナピューレを製造すると、硬さが1×10N/m以下であり、粘度が1.5Pa・s以上の物性を有し、非常に明るい色調を有し、バナナ本来の香味が優れたバナナピューレが得られることが分かる。 From the results in Table 2, the ripening level 4 banana with a blackened skin is very soft, so it is easily damaged by cutting and other handling. Although the color tone is slightly inferior, when Panana puree is produced from bananas with sugar spots that have begun to appear on the ripeness of 3 peels, the hardness is 1 × 10 4 N / m 2 or less and the viscosity is 1.5 Pa · s or more. It can be seen that a banana puree having the above physical properties, a very bright color tone, and an excellent banana original flavor can be obtained.
