Description
本発明は、透明容器入り飲食品に関し、特に、茶類を含む飲食品を透明容器内に充填してなる透明容器入り飲食品に関する。 The present invention relates to a food / beverage product in a transparent container, and in particular, relates to a food / beverage product in a transparent container formed by filling a food / beverage product containing tea in a transparent container.
近年、茶類入り飲食品の多様化に伴い、茶系飲料、茶類入りアイスクリーム、茶類入りデザートなどの様々なタイプの飲食品類が開発されている。特に、消費者の自然志向の中で、天然素材である茶類を含む飲食品が人気を集めている In recent years, with the diversification of tea-containing foods and drinks, various types of foods and drinks such as tea-based drinks, tea-containing ice creams, and tea-containing desserts have been developed. In particular, food and beverages including tea, which is a natural material, are gaining popularity among consumers' natural orientation.
茶類を含む飲食品の中でも、アイスクリーム類を例に、以下、その問題点などを説明する。
店頭で陳列され販売されるアイスクリーム類は、一般的に、遮光性の紙容器あるいはプラスチック容器に包装されて提供されることが多い。また、茶類を含むアイスクリーム類も、一般的に、遮光性の紙容器あるいはプラスチック容器に包装されて提供されることが多い。
しかし、一般的に、遮光性の容器は、内容物の特長である色調の鮮やかな茶類が入っていたり、乳白色のアイスクリームと他の色の茶類の混ぜ方を工夫して、様々な模様を施している場合であっても、容器自体に透明性がないため、茶類を含むアイスクリームを外側からは目視できず、商品価値をアピールすることができない。Among the foods and drinks including teas, the problems will be described below by taking ice cream as an example.
In general, ice creams that are displayed and sold in stores are often provided in light-shielding paper containers or plastic containers. In general, ice creams including tea are often provided in light-shielding paper containers or plastic containers.
In general, however, light-shielding containers contain vibrant teas that are characteristic of their contents, and various methods have been devised to mix milky white ice cream with other colors of tea. Even in the case where a pattern is applied, since the container itself is not transparent, ice cream containing tea cannot be visually observed from the outside, and the commercial value cannot be appealed.
そのため、茶類を含むアイスクリーム類を透明容器に入れたものも販売されている。しかし、一般に、透明容器を用いた場合、茶類を含むアイスクリーム類は、店頭陳列時に太陽光や蛍光灯などの光に曝露され、乳脂肪、植物油脂等に起因すると推測されるオフフレーバーを発生させる。このオフフレーバーの主な成分は、ある種のアルデヒド類、ケトン類などである。オフフレーバーは、商品の風味や品質に影響を及ぼして、商品価値を著しく損なう可能性がある。 Therefore, ice cream containing teas in a transparent container is also sold. However, in general, when transparent containers are used, ice cream including tea is exposed to light such as sunlight and fluorescent light at the time of store display, and has an off-flavor presumed to be caused by milk fat, vegetable oil, etc. generate. The main components of this off flavor are certain aldehydes, ketones and the like. Off-flavor can affect the flavor and quality of a product and can significantly impair the value of the product.
従来、アイスクリーム類などの油脂含有食品の熱や光による酸化などに起因する劣化を防止するための技術として、特定の種類の酸化防止剤を添加する方法(特許文献1など)、紫外線の遮光に重点を置き、焼成ブラック及び/又はアニリンブラックを配合した容器を用いる方法(特許文献2など)、アイスクリームの平均脂肪粒子径及び遊離脂肪率を調整して、酸化を抑制する方法(特許文献3)、氷菓又はアイスクリーム類に、不活性ガスから成る気泡を含有させる方法(特許文献4)などが知られている。
Conventionally, as a technique for preventing deterioration due to heat or light oxidation of oil-and-fat-containing foods such as ice creams, a method of adding a specific type of antioxidant (such as Patent Document 1), ultraviolet light shielding Emphasis on the method of using a container containing baked black and / or aniline black (
しかし、特許文献1の技術のように酸化防止剤などの食品添加物を使用した場合には、本来の風味を損なう可能性がある。また、特許文献2に記載されている容器は、透明容器とは異なり、実質的に内容物を外側から目視することができず、茶類などを含有してもその商品価値を視覚的に高めることができない。また、特許文献3〜4に記載されているような、脂肪粒子径などを調整したり、不活性ガスを気泡として含有させるなどの技術は、特殊な製造工程を必要とし、製造コストを増大させる。
However, when food additives such as antioxidants are used as in the technique of
緑茶や抹茶などの茶類の浸出液中の脂肪の含量はほぼ0%であり、茶類由来の脂肪による光照射による劣化は起こらないと考えられる。一方、太陽光あるいは蛍光灯の光照射により、光照射後の茶類の浸出液の風味が変化することも、一般的に知られている。 The content of fat in the exudate of teas such as green tea and matcha is almost 0%, and it is considered that deterioration due to light irradiation by fats derived from teas does not occur. On the other hand, it is also generally known that the flavor of tea exudate after light irradiation changes due to the light irradiation of sunlight or a fluorescent lamp.
したがって、本発明は、太陽光や蛍光灯の影響を受けやすい店頭に陳列して販売されるアイスクリーム類、デザート類などの透明容器入り飲食品、特に、茶類を含む飲食品を内容物として含み、かつ、容器として透明容器を用いた場合であっても、光曝露による酸化に起因するオフフレーバーの発生を大きく抑制することのできる、透明容器入りの飲食品を提供することを課題とする。 Therefore, the present invention includes foods and drinks in transparent containers such as ice creams and desserts that are sold and sold in stores that are easily affected by sunlight and fluorescent lamps, especially foods and drinks including teas as contents. Even if it is a case where a transparent container is used as a container, it is an object to provide a food / beverage product in a transparent container that can greatly suppress the occurrence of off-flavor due to oxidation due to light exposure. .
本発明者らは上記従来の問題点に鑑み鋭意研究を進めたところ、特定の透明容器を、茶類を含む飲食品類の容器として使用すれば、オフフレーバーの発生を抑制することができることを発見し、本発明を完成した。 The present inventors have conducted intensive research in view of the above-mentioned conventional problems, and found that if a specific transparent container is used as a container for foods and drinks including teas, the occurrence of off-flavor can be suppressed. The present invention has been completed.

An off-flavor suppressing method characterized by filling an article is provided.
本発明の透明容器入り飲食品は、太陽光や蛍光灯の影響を受けやすい店頭に陳列販売された場合であっても、光曝露による酸化に起因するオフフレーバーの発生量が少ないという利点を有する。本発明によれば、例えば、飲食時に金属臭や生臭臭(生臭い臭い)や油臭などのオフフレーバーを呈さないアイスクリーム類やデザート類などの飲食品類を提供することができる。また、ショーケースなどにおける店頭陳列であっても、長期販売が可能となる。 The food and drink in a transparent container of the present invention has the advantage that the amount of off-flavor generated due to oxidation due to light exposure is small even when sold in stores that are easily affected by sunlight or fluorescent lights. . ADVANTAGE OF THE INVENTION According to this invention, food / beverage products, such as ice cream and desserts which do not exhibit off-flavors, such as a metal odor, a raw odor (raw smell), and an oily odor, can be provided, for example. In addition, long-term sales are possible even for store displays in showcases and the like.
また、本発明によれば、透明容器を用いているので、内容物を外側から目視することができ、商品価値を確実にアピールすることができる。例えば、内容物の特長である茶類が入っている状態や、円筒状のアイスクリームの周りに茶類入り氷菓を配置している状態や、乳白色のアイスクリームと、他の色の茶類入りアイスクリームもしくは茶類入りソースなどを層状に交互に配したり混ぜたりすることによって様々な模様を施した状態を、確実にアピールすることができる。特に、視覚をもって商品アピールのできる抹茶などの茶類入りデザート類や、抹茶などの茶類入りアイスクリーム類や、茶類入り飲料などにおいて、大きな効果を期待することができる。 Moreover, according to this invention, since the transparent container is used, the contents can be visually observed from the outside, and the commercial value can be surely appealed. For example, it contains tea that is a feature of the contents, a state in which ice confectionery is placed around a cylindrical ice cream, milky white ice cream, and other colors of tea By arranging or mixing ice cream or tea sauce in layers, the state with various patterns can be surely appealed. In particular, a great effect can be expected in desserts containing tea such as Matcha, which can visually appeal to products, ice cream containing teas such as Matcha, beverages containing tea, and the like.

Six lacto ice (trade name: Essel Super Cup Mini Matcha; content: 90 ml; manufactured by Meiji Co., Ltd.) containing Matcha in a transparent container was prepared. The container was made of polystyrene and sealed with a transparent film.
Each of the six samples is divided into a light-shielding film (red, blue, yellow, green) having high absorption characteristics in a specific wavelength region, an aluminum foil (control as a substantially light-shielded state), and a transparent film (as a light-transmitting state). Covered with either). Each sample was subjected to an exposure test in which light of about 2,000 lux was irradiated for 2 days under the condition of being frozen at a temperature of −25 ° C.
Then, the aromatic component analysis was implemented by the method shown below.
In addition, the sample using the green and blue light-shielding film is an Example applicable to this invention, as shown in FIG. A sample using a red and yellow light-shielding film, a sample using an aluminum foil, and a sample using a transparent film are comparative examples not corresponding to the present invention. However, there is a possibility that the color that approximates each of the above-described colors, which is a comparative example, may include one that substantially blocks light in a specific wavelength region defined in the present invention. That is, the transparent container used in the present invention can have any color as long as it satisfies the conditions of the transparent container defined in the present invention.
[香気成分の測定方法]
光照射後の各試料の内容物2g及び飽和食塩水8gを、分析用容器(容量:20ml)中に収容した後、この分析用容器内のヘッドスペース中の香気成分を、固相マイクロ抽出(抽出条件:60℃、40分間、固相マイクロファイバー:SPME fiber 50/30μm DVB/Carboxen/PDMS、SUPELCO社製)により抽出した。その後、GC/MS分析(装置:6890N/5975、Agilent社製;GC用カラム:DB−WAX、J&W社製;測定条件:250℃、5分間;GCオーブン温度:40℃(5分間)→(15℃/分の昇温)→250℃(10分間);全イオン検出モード(質量範囲:m/z 35−300))によって、香気成分の量を測定した。
測定は、「2−Heptenal」(2−ヘプテナール)、「2−Octenal」(2−オクテナール)及び「1−Octen−3−one」(1−オクテン−3−オン)について行なった。これら3種の成分は、酸化の指標成分である。対照である透明のフィルムを施した試料での、これら3種の成分の生成量を100とした場合に、オフフレーバーの指標物質としている「2−Heptenal」、「2−Octenal」及び「1−Octen−3−one」の検出量の相対値を算出することで、各試料間のオフフレーバー抑制効果の優劣を比較した。[Measurement method of aroma components]
After storing 2 g of the contents of each sample after irradiation and 8 g of saturated saline in an analysis container (capacity: 20 ml), the aroma components in the head space in the analysis container are extracted by solid-phase microextraction ( Extraction conditions: 60 ° C., 40 minutes, solid phase microfiber: SPME fiber 50/30 μm DVB / Carboxen / PDMS, manufactured by SUPELCO). Then, GC / MS analysis (apparatus: 6890N / 5975, manufactured by Agilent; GC column: DB-WAX, manufactured by J &W; measurement conditions: 250 ° C., 5 minutes; GC oven temperature: 40 ° C. (5 minutes) → ( 15 ° C./min temperature increase) → 250 ° C. (10 min); total ion detection mode (mass range: m / z 35-300))).
The measurement was performed on “2-Heptenal” (2-heptenal), “2-Octenal” (2-octenal), and “1-Octen-3-one” (1-octen-3-one). These three components are oxidation indicator components. “2-Heptenal”, “2-Octualal”, and “1- By calculating the relative value of the detection amount of “Octen-3-one”, the superiority or inferiority of the off-flavor suppression effect between the samples was compared.
[吸収スペクトルの測定]
前記の各フィルムの波長300nm〜800nmにおける吸収スペクトルを、分光光度計(V−530;日本分光(株)製)を用いて測定した。その結果を図1に示す。[Measurement of absorption spectrum]
The absorption spectrum at a wavelength of 300 nm to 800 nm of each film was measured using a spectrophotometer (V-530; manufactured by JASCO Corporation). The result is shown in FIG.
[香気成分の測定結果]
香気成分の測定の結果、酸化の指標成分である「2−Heptenal」、「2−Octenal」及び「1−Octen−3−one」の生成量(相対値)は、透明フィルムを施した試料での生成量を100(基準値)とした場合に、以下のとおりであった。
アルミ箔を施した試料の相対値は、18(2−ヘプテナール)、22(2−オクテナール)、23(1−オクテン−3−オン)であった。
青色の遮光性フィルムを施した試料の相対値は、43(2−ヘプテナール)、53(2−オクテナール)、51(1−オクテン−3−オン)であった。
緑色の遮光性フィルムを施した試料の相対値は、52(2−ヘプテナール)、62(2−オクテナール)、60(1−オクテン−3−オン)であった。
赤色の遮光性フィルムを施した試料の相対値は、65(2−ヘプテナール)、71(2−オクテナール)、77(1−オクテン−3−オン)であった。
黄色の遮光性フィルムを施した試料の相対値は、98(2−ヘプテナール)、96(2−オクテナール)、103(1−オクテン−3−オン)であった。
これらの試験結果を図2に示す。[Measurement results of aroma components]
As a result of the measurement of the aroma component, the production amount (relative value) of “2-Heptenal”, “2-Octenal” and “1-Octen-3-one”, which are the index components of oxidation, is a sample subjected to a transparent film. When the production amount of 100 was 100 (reference value), it was as follows.
The relative value of the sample which gave aluminum foil was 18 (2-heptenal), 22 (2-octenal), and 23 (1-octen-3-one).
The relative value of the sample which gave the blue light-shielding film was 43 (2-heptenal), 53 (2-octenal), 51 (1-octen-3-one).
The relative value of the sample which gave the green light-shielding film was 52 (2-heptenal), 62 (2-octenal), 60 (1-octen-3-one).
The relative value of the sample which gave the red light-shielding film was 65 (2-heptenal), 71 (2-octenal), 77 (1-octen-3-one).
The relative value of the sample which gave the yellow light-shielding film was 98 (2-heptenal), 96 (2-octenal), 103 (1-octen-3-one).
The test results are shown in FIG.
前記のとおり、緑色と青色のいずれかの遮光性フィルムを施した試料の相対値は、2−ヘプテナール、2−オクテナール及び1−オクテン−3−オンのいずれについても、透明フィルムを施した試料の基準値に比べて、非常に小さかった(図2参照)。すなわち、緑色と青色のいずれかの遮光性フィルムを施した場合、550nm〜720nmの波長領域において実質的に遮光されることが、図1のスペクトルデータより明らかであり、この波長領域を遮光する透明容器であれば、光照射によるオフフレーバーの生成を抑制できることがわかった。
一方、黄色の遮光性フィルムを施した試料の相対値は、透明フィルムを施した試料の基準値と同等レベルであった。赤色の遮光性フィルムを施した試料の相対値は、透明フィルムを施した試料の基準値に比べて小さかったものの、緑色と青色のいずれかの遮光性フィルムを施した場合に比べて、大きかった。As described above, the relative value of the sample subjected to the light-shielding film of either green or blue is that of the sample subjected to the transparent film for any of 2-heptenal, 2-octenal and 1-octen-3-one. It was very small compared to the reference value (see FIG. 2). That is, when any one of the green and blue light-shielding films is applied, it is clear from the spectral data of FIG. 1 that the light is substantially shielded in the wavelength region of 550 nm to 720 nm. It turned out that the production | generation of the off-flavor by light irradiation can be suppressed if it is a container.
On the other hand, the relative value of the sample to which the yellow light-shielding film was applied was at the same level as the reference value of the sample to which the transparent film was applied. The relative value of the sample subjected to the red light-shielding film was smaller than the reference value of the sample subjected to the transparent film, but was larger than the case where either the green or blue light-shielding film was applied. .
[実験例2]
抹茶とキサンタンガムと水の合計量中で、抹茶の割合が1.6重量%、キサンタンガムの割合が0.2重量%になるように水と混合して、分散液を調製した。
次いで、この分散液160gを透明容器に入れて、4個の試料(透明容器入り飲食品を模したもの)を作製した。
4個の試料の各々を、特定の波長領域に高い吸光特性を有する遮光性フィルター(青色、緑色)、アルミ箔(略遮光状態としての対照)、及び透明フィルム(透光状態としての対照)のいずれかで覆った。それぞれの試料について、−25℃の温度で冷却させた状態下で、約2,000ルクスの光を2日間照射する曝露試験を行った。その後、以下に示す方法によって、香気成分分析を実施した。。[Experiment 2]
A dispersion was prepared by mixing with water such that the proportion of matcha tea was 1.6% by weight and the proportion of xanthan gum was 0.2% by weight in the total amount of matcha, xanthan gum and water.
Next, 160 g of this dispersion was placed in a transparent container to prepare four samples (simulating food and drink in a transparent container).
Each of the four samples is made up of a light-shielding filter (blue, green) having high light absorption characteristics in a specific wavelength region, an aluminum foil (control as a substantially light-shielding state), and a transparent film (control as a light-transmitting state). Covered with one. About each sample, the exposure test which irradiates about 2,000 lux light for 2 days was performed in the state cooled at the temperature of -25 degreeC. Then, the aromatic component analysis was implemented by the method shown below. .
各試料の内容物(分散液)2g及び飽和食塩水8gを、分析用容器(容量:20ml)中に収容した後、この分析用容器内のヘッドスペース中の香気成分を、固相マイクロ抽出(抽出条件:60℃、40分間、固相マイクロファイバー:SPME fiber 50/30μm DVB/Carboxen/PDMS、SUPELCO社製)により抽出した。その後、GC/MS分析(装置:6890N/5975、Agilent社製;GC用カラム:DB−WAX、J&W社製;測定条件:250℃、5分間;GCオーブン温度:40℃(5分間)→(15℃/分の昇温)→250℃(10分間);全イオン検出モード(質量範囲:m/z 35−300))によって、香気成分の量を測定した。
測定は、「2−Heptenal」(2−ヘプテナール)及び「1−Octen−3−one」(1−オクテン−3−オン)について行なった。これら2種の成分は、酸化の指標成分である。対照である透明のフィルムを施した試料での、これら2種の成分の生成量を100とした場合に、オフフレーバーの指標物質としている「2−Heptenal」及び「1−Octen−3−one」の検出量の相対値を算出することで、各試料間のオフフレーバー抑制効果の優劣を比較した。After 2 g of the contents of each sample (dispersion) and 8 g of saturated saline were placed in an analysis container (capacity: 20 ml), the aroma components in the head space in the analysis container were subjected to solid-phase microextraction ( Extraction conditions: 60 ° C., 40 minutes, solid phase microfiber: SPME fiber 50/30 μm DVB / Carboxen / PDMS, manufactured by SUPELCO). Then, GC / MS analysis (apparatus: 6890N / 5975, manufactured by Agilent; GC column: DB-WAX, manufactured by J &W; measurement conditions: 250 ° C., 5 minutes; GC oven temperature: 40 ° C. (5 minutes) → ( 15 ° C./min temperature increase) → 250 ° C. (10 min); total ion detection mode (mass range: m / z 35-300))).
The measurement was performed on “2-Heptenal” (2-heptenal) and “1-Octen-3-one” (1-octen-3-one). These two kinds of components are index components for oxidation. “2-Heptenal” and “1-Octen-3-one”, which are off-flavor indicator substances, when the amount of these two components produced in a sample with a transparent film as a control is defined as 100 By calculating the relative value of the detection amount, the superiority or inferiority of the off-flavor suppression effect between the samples was compared.
アルミ箔を施した試料の相対値は、19(2−ヘプテナール)、14(1−オクテン−3−オン)であった。
青色の遮光性フィルムを施した試料の相対値は、29(2−ヘプテナール)、52(1−オクテン−3−オン)であった。
緑色の遮光性フィルムを施した試料の相対値は、62(2−ヘプテナール)、65(1−オクテン−3−オン)であった。
これらの試験結果を図3に示す。
前記のとおり、緑色と青色のいずれかの遮光性フィルムを施した試料の相対値は、2−ヘプテナール及び1−オクテン−3−オンのいずれについても、透明フィルムを施した試料の基準値に比べて、非常に小さかった(図3参照)。The relative value of the sample which gave aluminum foil was 19 (2-heptenal) and 14 (1-octen-3-one).
The relative value of the sample which gave the blue light-shielding film was 29 (2-heptenal) and 52 (1-octen-3-one).
The relative value of the sample which gave the green light-shielding film was 62 (2-heptenal) and 65 (1-octen-3-one).
The test results are shown in FIG.
As described above, the relative value of the sample subjected to either the green or blue light-shielding film is higher than the reference value of the sample subjected to the transparent film for both 2-heptenal and 1-octen-3-one. It was very small (see FIG. 3).
