Description

本発明は、柑橘系果物の白皮(中果皮)を加工する方法に関する。より詳細には、白皮に果肉・果汁を添加して製菓材料等に利用できるように加工する方法に関する。   The present invention relates to a method for processing a citrus fruit white skin (mesocarp). More specifically, the present invention relates to a method of processing so that pulp and fruit juice can be added to the white skin and used for confectionery materials.

柑橘系果物は、一般的に果皮に柑橘系香気成分(リモネン)が含有されていて、果実・果汁にはその成分は殆ど存在しない。このため果実・果汁の加工品であるジュース(ピューレ)のスイーツへの応用は限定的であった。一方、果皮は苦味を伴うものが多く、利用方法には限界があり、なかでも中果皮は廃棄されることが多かった。こうしたことから柑橘系果物のスイーツへの材料形体は、果肉のシロップ漬け、果汁の濃縮還元、果皮のマーマレード、果汁・果肉のジャムやコンフィチュールとなっていた。   Citrus fruits generally contain a citrus aroma component (limonene) in the pericarp, and there are almost no components in fruits and fruit juices. For this reason, the application to the sweet of the juice (pure) which is a processed product of fruit and fruit juice was limited. On the other hand, many peels have a bitter taste, and there are limits to how they can be used. In particular, the mesocarp was often discarded. For this reason, the material forms of citrus fruit sweets were fruit syrup pickling, fruit juice concentration reduction, fruit marmalade, fruit juice / fruit pulp jam and conformity.

また、柑橘類果皮を加工する方法としては、特開2007−97592号公報(特許文献1)に記載の方法があるが、特許文献1に記載の方法は、外果皮の使用が必須であり、また、寒天状の物質を生成するため用途が限定されていた。   Moreover, as a method of processing citrus peel, there is a method described in Japanese Patent Application Laid-Open No. 2007-97592 (Patent Document 1), but the method described in Patent Document 1 requires the use of an outer skin, In order to produce an agar-like substance, the use was limited.

That is, the present invention is primarily a method for processing a white skin in citrus fruits, (1) a pretreatment step in which the white skin is hydrated and irradiated with microwaves, and (2) a white skin obtained in the pretreatment step. In addition, a processing method for a white skin, comprising a step of adding a pulp and / or juice and boiled to make Brix 50 or more.
Second, the method for processing a white skin according to the first aspect, characterized in that the hydration is performed by adding water of 10 to 30% of the weight of the white skin.
Third, the method for processing a white skin according to the first or second aspect, wherein the microwave irradiation is performed in a microwave oven at 600 W for 3 minutes.
Fourthly, in the preparation process, the flesh and / or juice is concentrated before being added to the white skin. This is a processing method.
Fifth, the concentration method is performed by adding saccharides and / or acids.

本発明における柑橘系果物とは、外果皮、白皮(中果皮)、果実・果汁を含むものであれば特に制限されないが、オレンジ、グレープフルーツ、カボス、シークヮーサー、スダチ、ダイダイ、ユズ、ライム、レモン、夏ミカン、ハッサク、日向夏、デコポン、伊予柑、ブンタン、温州ミカン、ポンカン、カラタチ、キンカン、へべすなどを例示することができる。   The citrus fruit in the present invention is not particularly limited as long as it includes outer skin, white skin (medium skin), fruit and juice, but orange, grapefruit, kabosu, shikwasa, sudachi, daidai, yuzu, lime, lemon Summer mandarin orange, Hassaku, Hyuga summer, Dekopon, Iyokan, Bungtan, Wenzhou mandarin orange, Ponkan, Karatachi, Kumquat, Hesperus and the like can be exemplified.

白皮(中果皮)とは、果皮の内側であって、白く柔らかい綿状または繊維質をしており、アルベドとも呼ばれるものである。   The white skin (mesocarp) is the inside of the skin and is white and soft cotton or fiber, and is also called albedo.

本発明において、柑橘系果物から採取した白皮は、まず、加水され、マイクロ波を照射される下処理工程が実施される。加水なしでマイクロ波を照射すると白皮がカサカサになるため好ましくない。一方、加水後、マイクロ波照射の代わりに加熱して煮ると、日向夏のようにふわふわした食感の白皮の場合には、原形が残らず好ましくない。なお、白皮は、果物から採取した状態のものでも、冷凍又は乾燥させたものでも使用可能である。   In the present invention, a white skin sampled from citrus fruits is first subjected to a pretreatment process in which it is hydrated and irradiated with microwaves. Irradiation with microwaves without hydration is not preferable because the rind becomes crisp. On the other hand, heating and simmering instead of microwave irradiation after hydration is not preferable in the case of a white skin with a fluffy texture like summer in the sun. In addition, the white skin can be used either in a state of being collected from fruits, or in a frozen or dried state.

加水される水の量は、白皮の厚さや硬さによるが、採取直後の白皮の重量の10〜30%、好ましくは15〜25%である。   The amount of water to be added depends on the thickness and hardness of the white skin, but is 10 to 30%, preferably 15 to 25% of the weight of the white skin immediately after collection.

本発明におけるマイクロ波の照射は、白皮の食感を改善すると共に殺菌も兼ねる。マイクロ波の照射は、電子レンジで600W、3分間を基準として、白皮の厚さや硬さ、電子レンジのワット数に応じて、より長時間または短時間にするなど調整することができる。   The microwave irradiation in the present invention improves the texture of the white skin and also serves as sterilization. The microwave irradiation can be adjusted to a longer time or a shorter time depending on the thickness and hardness of the white skin and the wattage of the microwave oven based on 600 W for 3 minutes in the microwave oven.

下処理工程が実施された白皮は、次に、柑橘系果物の果肉及び/又は果汁を添加され、煮詰めてBrix50以上とする仕込み加工工程が実施される。ここで、白皮と、果肉及び果汁とは、同じ柑橘系果物由来のものでも、異なる柑橘系果物由来のものでもよく、さらには、異なる柑橘系果物由来の白皮を組み合わせることも、異なる柑橘系果物由来の果肉及び果汁を組み合わせることもできる。   Next, the white skin that has been subjected to the pretreatment process is added with pulp and / or fruit juice of citrus fruits, and a preparation process is performed to boil and make Brix 50 or more. Here, the white bark, the flesh and the fruit juice may be derived from the same citrus fruit or different citrus fruits, and further, the white bark derived from different citrus fruits may be combined. It is also possible to combine pulps and juices derived from fruits.

白皮に添加する果肉及び/又は果汁は、好適には濃縮したものである。煮詰めて糖度を上げる段階が短時間で行えるからである。また、果肉及び/又は果汁の濃縮は、糖類や酸を添加して行うことができる。濃縮時に酸を添加すると果肉及び/又は果汁の褐変を防止することができる。ここで、本発明において使用できる糖類としては、蔗糖、でん粉糖(ブドウ糖、水飴を含む)を例示することができる。また、本発明において使用できる酸としては、クエン酸、リンゴ酸、コハク酸、乳酸、酢酸、アスコルビン酸を例示することができる。   The pulp and / or fruit juice added to the white skin is preferably concentrated. This is because the step of increasing the sugar content by boiling can be performed in a short time. Moreover, concentration of a pulp and / or fruit juice can be performed by adding saccharides and an acid. When an acid is added at the time of concentration, browning of the pulp and / or fruit juice can be prevented. Here, examples of the saccharide that can be used in the present invention include sucrose and starch sugar (including glucose and starch syrup). Examples of acids that can be used in the present invention include citric acid, malic acid, succinic acid, lactic acid, acetic acid, and ascorbic acid.

果肉及び/又は果汁を添加した白皮は、100℃以上での加熱を十分に行い、Brix50以上にする。ここで、Brix値は、水分の蒸発に依存するため、100℃以上での加熱時間により調整される。また、この時に糖類を添加しても構わない。なお、Brix50未満では、白皮が腐敗し易くなるなどの弊害が生じる場合がある。   The white skin to which the pulp and / or fruit juice has been added is sufficiently heated at 100 ° C. or higher to make Brix 50 or higher. Here, since the Brix value depends on the evaporation of moisture, it is adjusted by the heating time at 100 ° C. or higher. At this time, saccharides may be added. In addition, if it is less than Brix50, bad effects, such as a white skin becoming easy to rot, may arise.

本発明によると、従来廃棄されていた白皮を活用し、柑橘系の味、香りを吸着させ、色彩や食感に優れた製菓材料等の新しい利用価値を生み出すことができる。具体的には、製菓に彩りを与えつつ白皮の風味やリンゴのようなサクサクした食感を楽しむ等、様々な用途に利用可能である。   According to the present invention, it is possible to create a new utility value such as a confectionery material excellent in color and texture by adsorbing a citrus taste and fragrance by utilizing a white skin that has been discarded. Specifically, it can be used for various purposes such as enjoying the flavor of white skin and the crispy texture like apple while coloring confectionery.
