Description
本発明は特定の食品に用いられる容器において、容器に印刷されたインキ層の着色又は変色を抑制する方法に関し、更にはそのような着色又は変色が抑制された容器及び該容器入り食品に関する。 The present invention relates to a method for suppressing coloring or discoloration of an ink layer printed on a container in a container used for a specific food, and further relates to a container in which such coloring or discoloration is suppressed and the food in the container.
食品にフレーバー（香料）を添加し食品の付加価値を高めることは通常行われている。また一般に、食品用容器における最内層は食品衛生上ポリエチレン層等のポリオレフィン層が汎用され、食品の内容が消費者に容易に理解・判断できるよう、通常、商品説明や商品名、製造元などを記したインキ層を有する。 Increasing the added value of food by adding flavor (fragrance) to food is usually performed. In general, the innermost layer in food containers is a polyolefin layer such as a polyethylene layer for food hygiene, and usually describes the product description, product name, manufacturer, etc. so that consumers can easily understand and judge the contents of food. Having an ink layer.
フレーバーは最内層であるポリオレフィン層を透過する性質のものが多いため、流通期間や温度等の保管環境によっては、その外側のインキ層に達することがある。しかしながら、フレーバーがインキ層に与える影響は小さく、これらの成分がインキ層に達した場合でもインキ層の着色又は変色が大きな問題となることはなかった。 Since many flavors have a property of permeating through the polyolefin layer which is the innermost layer, depending on the storage environment such as the distribution period and temperature, the outer ink layer may be reached. However, the influence of the flavor on the ink layer is small, and even when these components reach the ink layer, coloring or discoloration of the ink layer did not become a big problem.
しかしながら本発明者らの知見によれば、食品中にフレーバーと糖が含まれる場合に生じることがある呈色物質がポリオレフィン層を透過し、インキ層に着色又は変色を引き起こすことがあることが分かった。 However, according to the knowledge of the present inventors, it has been found that a color-forming substance that may be generated when flavor and sugar are contained in food may penetrate the polyolefin layer and cause the ink layer to be colored or discolored. It was.
本発明は少なくともフレーバー及び糖を含む食品に用いる容器において、流通期間や保管環境によって生じることがある呈色物質による該容器のインキ層の着色又は変色を抑制する方法を提供することにあり、更には、インキ層の着色又変色が抑制された容器及び該容器入り食品を提供することにある。 It is an object of the present invention to provide a method for suppressing coloring or discoloration of an ink layer of a container by a coloring substance that may occur depending on a distribution period or a storage environment in a container used for food containing at least flavor and sugar. An object of the present invention is to provide a container in which coloring or discoloration of the ink layer is suppressed and a food contained in the container.
本発明者らは前記課題を解決すべく鋭意研究した結果、容器におけるインキ層の内側にポリエチレンテレフタレート層を設けることにより、前記呈色物質によるインキ層の着色又は変色が著しく抑制されることを見いだし本発明を完成させた。 As a result of diligent research to solve the above problems, the present inventors have found that by providing a polyethylene terephthalate layer inside the ink layer in the container, coloring or discoloration of the ink layer due to the coloring substance is remarkably suppressed. The present invention has been completed.

本発明の容器を構成する積層体の最内層のポリオレフィン層としては通常低密度ポリエチレンが好ましく用いられる。またポリプロピレンを用いることもできるがポリエチレンに比べ結晶性があり、この性質によりポリエチレンを用いた場合に比べ容器の耐衝撃性に劣ることがある。ポリオレフィン層の厚さは３０乃至８０μｍが好ましい。 Usually, low density polyethylene is preferably used as the innermost polyolefin layer of the laminate constituting the container of the present invention. Polypropylene can also be used, but it is more crystalline than polyethylene, and this property may result in inferior impact resistance of the container as compared to the case of using polyethylene. The thickness of the polyolefin layer is preferably 30 to 80 μm.
本発明の容器を構成する積層体のポリエチレンテレフタレート（以下、「ＰＥＴ」と称することがある）層に用いるＰＥＴは市販品を用いることができる。好ましいものとして東洋紡績（株）製Ｔ４１０２、ユニチカ（株）製エンプレットＰＴＭ、東洋紡績（株）エステルフィルムＥ５１０２及び東レ（株）ルミラーＰ６０ｃ等が挙げられる。ＰＥＴの厚さはインキの着色また変色に影響を与え、厚くすれば着色又は変色の抑制効果を上げることができ、容器の形態や内容物等の条件に応じてより適当な厚さを採用することができる。例えば、８〜２５μｍの範囲で好ましく用いることができ、更には９〜１５μｍの範囲で好ましく用いることができる。 Commercially available products can be used as the PET used for the polyethylene terephthalate (hereinafter sometimes referred to as “PET”) layer of the laminate constituting the container of the present invention. Preferable examples include T4102 manufactured by Toyobo Co., Ltd., an emblet PTM manufactured by Unitika Co., Ltd., an ester film E5102 manufactured by Toyobo Co., Ltd., and Lumirror P60c manufactured by Toray Industries, Inc. The thickness of the PET affects the coloration or discoloration of the ink, and if it is thickened, the effect of suppressing the coloration or discoloration can be increased, and a more appropriate thickness is adopted depending on the conditions of the container form and contents. be able to. For example, it can be preferably used in the range of 8 to 25 μm, and more preferably in the range of 9 to 15 μm.
本発明の容器を構成する積層体のインキ層はＰＥＴ層の外側に設けられ、通常用いられるフィルム用インキが用いることができる。特に呈色物質により影響を受けやすく、着色又変色の問題が大きいインキは白色である。この白色には通常チタンホワイトが使用されており、呈色物質により淡い黄色に変色することが多い。また白色以外のその他の色は、その色相を明瞭にするためチタンホワイトの上に印刷されていることが殆どである。したがって、呈色物質により本来の色相が明瞭に浮き出ず、全体として黄色味がかった色相になるという問題がある。 The ink layer of the laminate constituting the container of the present invention is provided outside the PET layer, and commonly used film inks can be used. In particular, an ink that is easily affected by a coloring substance and has a large problem of coloring or discoloration is white. Titanium white is usually used for this white color, and it often changes to a pale yellow color by the coloring substance. Further, other colors other than white are mostly printed on titanium white in order to clarify the hue. Therefore, there is a problem that the original hue does not clearly appear due to the colored substance, and the hue becomes yellowish as a whole.
本発明の容器を構成する積層体の保護層は、通常、延伸ポリプロピレン（ＯＰＰ）、Ｏ−ナイロン又はポリエチレンテレフタレートのいずれか１つのフィルムで形成すればよい。ＯＰＰフィルムとしては、東洋紡績（株）製パイレンフィルム―ＯＴ Ｐ２１６１の他サン・トックス（株）製サントックスＯＰ ＰＡ２０、東レ（株）トレファンＢＯ ２２４５タイプ、二村化学工業（株）製太閤ＦＯ ＦＯＲ、王子製紙（株）アルファンＳ ＳＹ−１０１等を用いることができる。フィルムの厚さは印刷面の保護を目的としているので通常は１０乃至３０μｍで充分である。 What is necessary is just to form the protective layer of the laminated body which comprises the container of this invention with the film of any one of an extending | stretching polypropylene (OPP), O-nylon, or a polyethylene terephthalate normally. As OPP films, Toyobo Co., Ltd. Pyrene Film-OT P2161, Sun Tox Co., Ltd. Santox OP PA20, Toray Industries, Inc. Trefan BO 2245 type, Nimura Chemical Industry Co., Ltd. Dazai FO FOR Oji Paper Co., Ltd. Alphan S SY-101 or the like can be used. Since the thickness of the film is intended to protect the printed surface, 10 to 30 μm is usually sufficient.
本発明の容器を構成する積層体のＰＥＴ層の外側及び内側には通常接着剤層が設けられる。この接着剤にはポリエステル系又ポリエーテル系のドライラミネート用接着剤が好ましく用いられる。これらを例示するならばポリエステル系では東洋モートン（株）製ＡＤ−９００、ポリエーテル系では武田薬品工業（株）製Ａ９６９Ｖ又東洋モートン（株）製ＴＭ３２９等が挙げられる。 Usually, an adhesive layer is provided on the outside and inside of the PET layer of the laminate constituting the container of the present invention. A polyester or polyether dry laminate adhesive is preferably used as the adhesive. Examples of these include polyester-based AD-900 manufactured by Toyo Morton Co., Ltd., and polyether-based products such as A969V manufactured by Takeda Pharmaceutical Co., Ltd. and TM329 manufactured by Toyo Morton Co., Ltd.
なお本発明の容器の形態は特に限定されず、可撓性を有する袋状の容器、スタンディングパウチ容器、ボトル状の容器等、各種の形態を採用することができる。 In addition, the form of the container of this invention is not specifically limited, Various forms, such as a flexible bag-shaped container, a standing pouch container, a bottle-shaped container, are employable.
本発明におけるフレーバーとしては、本発明の効果が発揮されるものであれば特に限定されないが、例えばシトラール、シンナムアルデヒド、フルフラール及びバニリン等のアルデヒド基を有するフレーバー、オイゲノール、アネトール及びクルクミン等の二重結合を有するフレーバー、マルトール及びフラノン誘導体等の環状エーテル化合物であるフレーバーを挙げることができる。またこれらの化合物の誘導体でフレーバーとして用いることができる化合物も本発明におけるフレーバーとして挙げることができる。例えば、エチルマルトール等のマルトール誘導体、フラネオール、ソトロン等のフラノン誘導体、エチルバニリン等のバニリン誘導体等の誘導体を挙げることができる。 The flavor in the present invention is not particularly limited as long as the effects of the present invention are exhibited. For example, flavors having aldehyde groups such as citral, cinnamaldehyde, furfural and vanillin, eugenol, anethole and curcumin Examples thereof include flavors having bonds, and flavors that are cyclic ether compounds such as maltol and furanone derivatives. Moreover, the compound which can be used as a flavor with the derivative | guide_body of these compounds can also be mentioned as a flavor in this invention. Examples thereof include derivatives such as maltol derivatives such as ethyl maltol, furanone derivatives such as furaneol and sotron, and vanillin derivatives such as ethyl vanillin.
本発明における糖としては、ぶどう糖、果糖、蔗糖、麦芽糖、乳糖、ソルビトール、マンニトール等の単糖類、重合度が低いオリゴ糖類、還元麦芽糖水飴などの糖アルコール類等を挙げることができる。 Examples of the sugar in the present invention include monosaccharides such as glucose, fructose, sucrose, maltose, lactose, sorbitol and mannitol, oligosaccharides having a low polymerization degree, and sugar alcohols such as reduced maltose starch syrup.
フレーバーの多くは液体であり、例えば商品が甘味料等の固体、粉末及び顆粒状の場合には、適当な担体に担持して用いられることがある。担体としては糖を用いることができる。 Many of the flavors are liquids. For example, when a product is a solid such as a sweetener, a powder, or a granule, it may be used by being supported on a suitable carrier. Sugar can be used as the carrier.
フレーバーと糖が共存した状態、あるいはフレーバーが糖に担持された状態で長期間経過した場合、フレーバーと糖の間で何らかの反応又は化学変化を起こし、呈色物質が生成することがある。またこのような呈色物質の多くは食品容器の最内層として汎用されているポリオレフィン層を通過するため、インキ層に到達した場合、インキ層が着色又は変色することがある。しかしながら、本発明のように容器のインキ層の内側にＰＥＴ層を設けることで、インキ層の着色又は変色を著しく抑制することができる。
When the flavor and sugar coexist, or when the flavor is supported on the sugar for a long time, some reaction or chemical change may occur between the flavor and the sugar, and a colored substance may be generated. In addition, since many of such colored substances pass through a polyolefin layer that is widely used as the innermost layer of food containers, the ink layer may be colored or discolored when it reaches the ink layer. However, by providing the PET layer inside the ink layer of the container as in the present invention, coloring or discoloration of the ink layer can be remarkably suppressed.
本発明における食品は本発明の効果が達成されるものであれば特に限定されないが、例えば糖を主成分とする甘味料等を好ましいものとして挙げることができる。 The food in the present invention is not particularly limited as long as the effects of the present invention can be achieved. For example, a sweetener mainly composed of sugar can be mentioned as a preferable one.
本発明を実施例により更に詳しく説明する。 The present invention will be described in more detail with reference to examples.

Comparative Example 1
From the outside of the laminate, OPP (Toyobo Co., Ltd., P2161 thickness 20 μm), printing layer ink (Toyo Ink Manufacturing Co., Ltd., New Fine), polyethylene (L - LDPE) (tama-1 UB-1 thickness 60 μm) ) Was laminated by a dry laminating method. A standing pouch is produced with this laminated film, and (1 ) 200 g of powdered reduced maltose starch syrup (97.2%), aspartame (2.1%) and fragrance (“Pal Sweet” (registered trademark) manufactured by Ajinomoto Co., Inc.) are sealed in this. (2) Sample in which 50 g of flavor D in which 2.5 g of maltol and 2.5 g of vanillin are supported on 95 g of dextrin was sealed, and (3) 2.5 g of maltol and 2.5 g of vanillin in 95 g of maltose Sample sealed with 50 g of flavor E, (4) Sample sealed with 50 g of aspartame, (5) Sample sealed with 194.4 g of maltose and 4.2 g of aspartame, (6) Sample sealed with 200 g of maltose, and (7) Dextrin A sample sealed with 200 g was prepared and subjected to an exposure test. Thereafter, the discoloration of the standing pouch container was measured, and then a 20 mm × 40 mm laminate of the white ink layer portion was cut out, and the absorbance of this film was measured. The results are shown in Table 2.
実施例と比較例では積層体構成が異なるので、吸光度と呈色の度合いを直接比較できない。そこで比較し易くするために、比較例の積層体構成の最内層がポリエチレン層と同じ実施例２及び３の空体の吸光度0.2323と0.2401の平均値0.2362を対照基準とした。次に実施例２及び３は比較例に対し積層体構成でＰＥＴ層１２μｍを設けているので、吸光度に対する影響を考慮し、比例計算でＰＥＴ層存在を仮定して比較例１の補正吸光度値を求めた。その結果を表２に合わせて示した。 Since the laminate structure is different between the example and the comparative example, the absorbance and the degree of coloration cannot be directly compared. Therefore, in order to facilitate comparison, the average value 0.2362 of the absorbances 0.2323 and 0.2401 of the empty bodies of Examples 2 and 3 in which the innermost layer of the laminate structure of the comparative example is the same as the polyethylene layer was used as a reference standard. Next, since Examples 2 and 3 are provided with a PET layer of 12 μm in a laminate structure with respect to the comparative example, the corrected absorbance value of Comparative Example 1 is calculated by assuming the presence of the PET layer by proportional calculation in consideration of the influence on the absorbance. Asked. The results are shown in Table 2.
実施例及び比較例の結果からインキ層を着色又は変色させる呈色物質はいずれもフレーバーと糖の存在する中で生成していることがわかる。一方パルスイートの原料であるアスパルテームはアミノ基を有しているものの糖と共存させてもこの暴露試験ではインキ層に変化が見られなかった。 From the results of Examples and Comparative Examples, it can be seen that any color-forming substance that colors or changes the color of the ink layer is produced in the presence of flavor and sugar. On the other hand, aspartame, the raw material of Palsweet, has an amino group, but the ink layer did not change in this exposure test even when it was coexisted with sugar.
以上の結果より、インキ層の内側にＰＥＴ層を設けた積層体を容器に採用することにより、フレーバー及び糖が長時間共存することにより発生した呈色物質による容器のインキ層の着色又は変色が著しく抑制されることが分かる。 From the above results, by adopting a laminate in which a PET layer is provided inside the ink layer for the container, coloring or discoloration of the ink layer of the container due to the colored substance generated when flavor and sugar coexist for a long time. It turns out that it is suppressed remarkably.
