Description

本発明は、熱や光によるクロロフィル含有食品の変色を抑制するための、クロロフィル含有食品用品質保持剤に関する。また、本発明は熱や光によるクロロフィル含有食品の変色を抑制する、クロロフィル含有食品の品質保持方法に関する。 TECHNICAL FIELD The present invention relates to a quality preserving agent for chlorophyll-containing foods for suppressing discoloration of chlorophyll-containing foods due to heat or light. The present invention also relates to a method for preserving the quality of a chlorophyll-containing food that suppresses discoloration of the chlorophyll-containing food due to heat or light.

抹茶やブロッコリー、インゲンマメ、枝豆、アスパラガス等の緑色野菜に含まれるクロロフィルは、一般にマグネシウムがテトラピロール環中心に配位した構造をしており、安全性の高い緑色色素として食品、化粧料等の着色に利用されている。 Chlorophyll contained in green vegetables such as green tea, broccoli, kidney beans, green soybeans, and asparagus generally has a structure in which magnesium is coordinated to the center of the tetrapyrrole ring, and is used as a highly safe green pigment in foods and cosmetics. Used for coloring.

しかしながら、クロロフィルは加熱や光(特に紫外線)照射により分解し、変色を引き起こしやすい。このような安定性の問題により、クロロフィルの用途や使用条件は制限されている。そのため、クロロフィルの安定化のための品質保持剤や品質保持方法が種々提案されている。 However, chlorophyll is easily decomposed by heating or irradiation with light (especially ultraviolet rays), causing discoloration. These stability issues limit the applications and conditions of use of chlorophyll. Therefore, various quality preserving agents and quality preserving methods for stabilizing chlorophyll have been proposed.

特許文献1には、炭酸マグネシウムを添加することにより、変色が抑制された茶そばの製造方法が記載されている。クロロフィルの分解はマグネシウムとテトラピロール環との配位構造が崩れることが原因の一つと考えられている。従って、特許文献1のように、炭酸マグネシウムのようなマグネシウム源を添加することで、クロロフィルの分解を抑制することが可能である。しかしながら、マグネシウム源の添加だけでは変色を十分に抑制することができず、さらにアスコルビン酸Naを加えてpHを7.0~8.0に調整した場合であっても、その変色抑制効果は未だ不十分であった。 Patent Literature 1 describes a method for producing tea buckwheat in which discoloration is suppressed by adding magnesium carbonate. One of the causes of chlorophyll decomposition is thought to be the collapse of the coordination structure between magnesium and the tetrapyrrole ring. Therefore, as in Patent Document 1, it is possible to suppress the decomposition of chlorophyll by adding a magnesium source such as magnesium carbonate. However, discoloration cannot be sufficiently suppressed by adding a magnesium source alone, and even when sodium ascorbate is added to adjust the pH to 7.0 to 8.0, the discoloration suppressing effect is still was inadequate.

特許文献2には、内側面に銅及び/又は亜鉛を含む合金地肌を露出した構造に形成してなる加熱容器中の温水または熱水中に溶出してくる銅イオンおよび亜鉛イオンの相互作用で植物由来緑色素を復元および/または定着するようにした湯煎による植物の緑色素復元・定着方法が記載されている。この方法では、クロロフィルの金属を銅イオンまたは亜鉛イオンに置換することでクロロフィルの色素をより鮮やかに保つことが可能である。しかしながら、このような方法では、溶出する金属イオン濃度の調整が困難であり、金属イオンが置換されるまで熱水に浸漬することで、他の栄養分の分解や溶出を招く等の問題があった。 In Patent Document 2, the interaction of copper ions and zinc ions eluted in warm water or hot water in a heating vessel formed into a structure in which an alloy surface containing copper and / or zinc is exposed on the inner surface A method for restoring/fixing a plant-derived green pigment by boiling in hot water for restoring and/or fixing a plant-derived green pigment is described. In this method, it is possible to keep the chlorophyll pigment brighter by replacing the chlorophyll metal with a copper ion or a zinc ion. However, with such a method, it is difficult to adjust the concentration of eluted metal ions, and immersion in hot water until the metal ions are replaced causes problems such as decomposition and elution of other nutrients. .

特許文献3には、特定のミネラルを増強した酵母を利用した植物の緑色の保持あるいは復元する方法が提案されている。しかしながら、ミネラル含有酵母は、酵母壁が硬く所定のミネラルの効果的な遊離が難しいことや、酵母体内のミネラル含有量が比較的少ない(亜鉛酵母の場合は亜鉛を5重量%含有)ことから、酵母を過剰に加える必要があった。また、特有の酵母臭が食品に付着し、臭いや味に影響が出るため、食品には使用し難いものであった。 Patent Document 3 proposes a method for maintaining or restoring the green color of plants using yeast enriched with specific minerals. However, mineral-containing yeast has a hard yeast wall, making it difficult to effectively release predetermined minerals. Had to add yeast in excess. In addition, the unique yeast odor adheres to food, affecting the odor and taste, making it difficult to use in food.

また、クロロフィルの分解は、酸化も原因の一つと考えられており、様々な抗酸化物質の添加によってクロロフィルの変色を抑制する方法が提案されている。抗酸化物質としては、例えば、β-カロテン(特許文献4)、α-リポ酸及びアスコルビン酸(特許文献5、特許文献6)等が挙げられるが、クロロフィルの分解には複数の要因が考えられ、そのメカニズムが複雑であることから、これらの化合物のみではクロロフィルの分解、変色を十分に抑制することが困難であった。 Oxidation is also considered to be one of the causes of the decomposition of chlorophyll, and methods for suppressing discoloration of chlorophyll by adding various antioxidant substances have been proposed. Antioxidants include, for example, β-carotene (Patent Document 4), α-lipoic acid and ascorbic acid (Patent Documents 5 and 6). Since the mechanism is complicated, it has been difficult to sufficiently suppress the decomposition and discoloration of chlorophyll using only these compounds.

そのため、食品の味質に対する影響が少なく、十分な変色抑制効果を有する品質保持剤が所望されていた。 Therefore, there has been a demand for a quality preserving agent that has little effect on the taste of food and has a sufficient effect of suppressing discoloration.

抹茶蒸しパンの色差測定
製造した抹茶蒸しパンをガスバリア性の高い包装袋(旭化成パックス株式会社製:KON15μm/60μm)に密閉した後、室温、蛍光灯による約1000ルクスの光照射下で1日間保管し、保管後の抹茶蒸しパンの色差を下記方法により測定した。結果を表1-1~1-3に示す。
<色差の測定方法>
色差の測定には測色色差計(日本電色工業株式会社製:ZE‐2000)を用いて、明度L値、色相a値(赤色⇔緑色)、色相b値(黄色⇔青色)を測定した。
製造直後の値をp、所定時間経過後の値をqの添え字で示すとき、下式により総合的な色の差であるΔEを算出した。
(式)ΔE=[(Lq-Lp)+(aq-ap)+(bq-bp)1/2
尚、ΔEは製造直後と所定時間経過後のL、a、bの数値の差を表す。よって、ΔEの数値が小さい程、製造直後からの変化が少なく、変色抑制効果が高いことを示す。(ΔE/対照のΔE)×100の値が65未満であるのが好ましく、55未満であるのがより好ましく、45未満であるのがさらに好ましく、40未満であるのが特に好ましい。
Color difference measurement of matcha steamed bread After sealing the manufactured matcha steamed bread in a packaging bag with high gas barrier property (manufactured by Asahi Kasei Pax Co., Ltd.: KON 15 μm/60 μm), it was stored at room temperature under illumination of about 1000 lux by a fluorescent lamp for 1 day. Then, the color difference of the green tea steamed bread after storage was measured by the following method. The results are shown in Tables 1-1 to 1-3.
<Method for measuring color difference>
A colorimetric color difference meter ( manufactured by Nippon Denshoku Industries Co., Ltd.: ZE-2000) was used to measure the color difference. was measured.
ΔE * , which is the overall color difference, was calculated by the following formula, where p indicates the value immediately after production and q indicates the value after the elapse of a predetermined time.
(Formula) ΔE * = [(L * q−L * p) 2 +(a * q−a * p) 2 +(b * q−b * p) 2 ] 1/2
ΔE * represents the difference in the numerical values of L * , a * , and b * immediately after production and after a predetermined time has passed. Therefore, the smaller the value of ΔE * , the smaller the change from immediately after production, and the higher the effect of suppressing discoloration. Preferably, the value of (ΔE * /ΔE * of control)×100 is less than 65, more preferably less than 55, even more preferably less than 45, and most preferably less than 40.

本発明の製剤A~Oのいずれかが配合された抹茶蒸しパン(実施例1~15)は、光照射下での保管試験における色差((ΔE/対照のΔE)×100)の値が、対照より明確に小さく、十分に変色が抑制されていることが確認された。また味質に関しても対照と遜色なく同等であった。一方、本発明以外の製剤P~Uのいずれかが配合された抹茶蒸しパン(比較例1~6)は、いずれも実施例1~15と比較して色差((ΔE/対照のΔE)×100)の値が大きく、変色抑制効果が十分ではなかった。 Matcha steamed bread (Examples 1 to 15) containing any of the formulations A to O of the present invention has a color difference ((ΔE * / ΔE * of control) × 100) in a storage test under light irradiation. was clearly smaller than the control, and it was confirmed that the discoloration was sufficiently suppressed. In addition, the taste was comparable to that of the control. On the other hand, the green tea steamed bread (Comparative Examples 1 to 6) containing any of the formulations P to U other than the present invention showed a color difference ((ΔE * /ΔE * of the control) compared to Examples 1 to 15. )×100) was large, and the effect of suppressing discoloration was not sufficient.
