【発明の属する技術分野】
本発明は、リノレン酸を多く含む風味良好で安定性の良い食用油に関する。
【０００２】
【従来の技術】
α−リノレン酸は、人間にとって必須脂肪酸であることが確かめられ（Holman R.T. et al., American Journal of Clinical Nutrition, ３５巻，６１７〜６２３頁（１９８２））、癌やアレルギーを抑制する働きがあるとの報告（奥山等「油脂の栄養と疾病」１６９〜１８５頁（１９９０））がる。また、γ−リノレン酸についても、アトピー性皮膚炎に対して治療効果を示すことから、イギリスでは治療薬として認められている（菅野等「食品と科学」５５〜５８頁（１９９３））。近年、リノレン酸を多く含む油脂が注目され、リノレン酸を多く含む油脂の開発が望まれている。
【０００３】
アマニ油、エゴマ油およびシソ油は、α−リノレン酸を総脂肪酸中に５０〜６５％と多く含んでいる。また、月見草油およびボラージ油は、γ−リノレン酸を総脂肪酸中に１０〜２５％含んでいる。これらの油脂は、従来食用に供されることもあるが、他の食用油脂に比べて不飽和脂肪酸が多く、保存安定性が著しく悪いため、現在ではわずかしか食用として利用されていない。即ち、これらのリノレン酸を多く含む油脂は、食用油として保存安定性が悪く、通常の搾油、精製処理して得られるアマニ油、エゴマ油、シソ油、月見草油およびボラージ油は、一般の食用油として使用することに支障がある。
【０００４】
【発明が解決しようとする課題】
したがって、本発明の目的は、風味が良好で風味安定性および酸化安定性に優れたリノレン酸を多く含む食用油を提供することにある。
【０００５】
【発明が解決するための手段】
前記目的を達成するために、本発明者らは鋭意検討を重ねた結果、アマニ種子、エゴマ種子、シソ種子、月見草種子またはボラージ種子から食用油を製造する工程において同時にゴマ種子を混合し搾油、精製処理することにより、処理過程で品質劣化が少なく風味が良好で風味安定性および酸化安定性に優れた食用油が得られることを見出した。本発明でいう精製処理とは、香味を特徴とする食用油にあっては、搾油して得られる原油に対し、ろ過処理を主体にした処理をいい、例としては、ゴマ油、ナッツ油、オリーブ油が挙げられる。香味の少ない食用油つまり食用サラダ油等にあっては、脱酸、脱色、脱臭の工程を経る処理をいい、必要に応じては脱ロウの工程を含むものである。さらに本発明者らは、アマニ種子、エゴマ種子、シソ種子、月見草種子またはボラージ種子から食用油を製造する工程において同時にゴマ種子を混合し焙煎・搾油・精製処理することにより、処理過程で品質劣化が少なく風味が良好で風味安定性および酸化安定性に優れた食用油が得られることを見出した。
【０００６】
【発明の実施の形態】
以下本発明を詳しく説明する。本発明は、きょう雑物を除去したアマニ種子、エゴマ種子、シソ種子、月見草種子、ボラージ種子の中から１種以上の種子に、きょう雑物を除去したゴマ種子を混合して搾油し、引き続き食用油の品質レベルまで精製処理する、またはきょう雑物を除去したアマニ種子、エゴマ種子、シソ種子、月見草種子、ボラージ種子の中から１種以上の種子に、きょう雑物を除去したゴマ種子を混合して焙煎・搾油し、引き続き食用油の品質レベルまで精製処理することを特徴とする食用油の製造法である。本発明でいう精製処理とは、香味を特徴とする食用油にあっては、搾油して得られる原油に対し、ろ過処理を主体にした処理をいい、香味の少ない食用油つまり食用サラダ油等にあっては、脱酸、脱色、脱臭等の工程を経る処理をいう。本発明におけるゴマ種子の混合比率は、望ましくは選択した種子に対して１０〜８０％の範囲において本発明の目的を達成するものである。ゴマ種子が１０％より少ない配合の場合は風味安定性、保存安定性が損なわれ、また、８０％より多い配合の場合は本発明の意図するリノレン酸含量が確保できない。
【０００７】
本発明でいう焙煎とは、搾油を行なう前に種子を直接もしくは間接に乾式または湿式で加熱処理することをいい、その加熱温度が１５０〜３５０℃で２〜６０分間処理することが望ましい。
【０００８】
かかる条件で焙煎したゴマ種子を含んだ種子を分別せず常法により蒸熱した後、圧搾または圧搾抽出することによって、香ばしいフレーバーを持つ茶褐色の原油が得られる。この原油をろ過工程のみで処理して最終製品とすることもでき、またこの原油を一般植物油脂と同様に脱酸−水洗−脱色−脱臭等の精製工程を経て最終製品とすることもできる。
【０００９】
一方、きょう雑物を除去したアマニ種子、エゴマ種子、シソ種子、月見草種子、ボラージ種子の中から１種以上をかかる条件下で焙煎して得られた焙煎当該種子を常法により蒸熱した後、圧搾または圧搾抽出して得られた原油に、同様に処理したゴマ原油を混合してろ過して得られる最終製品、もしくは、きょう雑物を除去したアマニ種子、エゴマ種子、シソ種子、月見草種子、ボラージ種子の中から１種以上をかかる条件下で焙煎して得られた焙煎当該種子を常法により蒸熱した後、圧搾または圧搾抽出して得られた原油を、一般植物油脂と同様に脱酸−水洗−脱色−脱臭等の精製工程を経て得られる精製油に同様に処理したゴマ精製油等を混合して得られる最終製品では、酸化安定性が悪く、保存時の風味安定性も悪く、経時的に特有の苦みを有するようになり、食用油として使用することには支障がある。
【００１０】
本発明は、アマニ種子、エゴマ種子、シソ種子、月見草種子、ボラージ種子の様に酸化安定性の悪い多価不飽和脂肪酸を多く含む種子の中から１種以上の種子と種子の形状が近似しているゴマ種子とを同時に搾油・精製処理する、あるいは、アマニ種子、エゴマ種子、シソ種子、月見草種子、ボラージ種子の中から１種以上の種子とゴマ種子とを同時に焙煎・搾油・精製処理することを特徴にしている。アマニ種子、エゴマ種子、シソ種子、月見草種子、ボラージ種子の中から１種以上の種子を焙煎し、別にゴマ種子を焙煎した後、両者を混合して搾油した場合も、両者を混合して焙煎・搾油した場合と同様の効果は得られる。しかし、別々に焙煎した場合、２基の焙煎設備が必要であり、経済的ではない。一方、１基の焙煎設備でそれぞれを焙煎した場合、アマニ種子、エゴマ種子、シソ種子、月見草種子、ボラージ種子またはそれらを混合した種子を後半に焙煎する必要があり、不合理である。効率性、経済性の面から見ればアマニ種子、エゴマ種子、シソ種子、月見草種子、ボラージ種子の中から１種以上の種子とゴマ種子とを最初に混合し、焙煎することが望ましい。
【００１１】
かくして得られる油脂は、リノレン酸を高濃度に含み、風味が良好で保存時の風味および酸化安定性に優れ、そのまま食用に供せられるものである。
【００１２】
本発明では、このようにして得られた油にトコフェロール、レシチン、緑茶抽出物、甘草抽出物、アスコルビン酸脂肪酸エステル等の抗酸化剤を添加することにより、さらに保存安定性を増すことができる。
【００１３】
また、本発明で得られる食用油と通常の食用油、即ちナタネ油、大豆油、とうもろこし油、小麦胚芽油、綿実油、オリーブ油、サフラワー油、ヒマワリ油等を原料とする食用油と任意の割合で配合し、食用として使用することもできる。

BACKGROUND OF THE INVENTION
The present invention relates to an edible oil that is rich in linolenic acid and has good flavor and stability.
[0002]
[Prior art]
α-linolenic acid has been confirmed to be an essential fatty acid for humans (Holman RT et al., American Journal of Clinical Nutrition, 35, 617-623 (1982)), and has a function of suppressing cancer and allergies. (Okuyama et al., “Nutrition and Disease of Oils and Fats”, pages 169-185 (1990)). Also, γ-linolenic acid is recognized as a therapeutic drug in the United Kingdom because of its therapeutic effect against atopic dermatitis (Ogino et al. “Food and Science”, pages 55-58 (1993)). In recent years, oils and fats rich in linolenic acid have attracted attention, and development of fats and oils rich in linolenic acid is desired.
[0003]
Linseed oil, sesame oil, and perilla oil contain a large amount of α-linolenic acid in the total fatty acid at 50 to 65%. Also, evening primrose oil and borage oil contain 10 to 25% of γ-linolenic acid in the total fatty acids. Although these fats and oils are conventionally used for food, they are used only for foods at present because they have more unsaturated fatty acids than other edible fats and oils and their storage stability is extremely poor. That is, these fats and oils containing a large amount of linolenic acid have poor storage stability as edible oils, and ordinary squeezed oil, linseed oil, egoma oil, perilla oil, evening primrose oil and borage oil obtained by refining treatment are generally There is a problem in using as oil.
[0004]
[Problems to be solved by the invention]
Accordingly, an object of the present invention is to provide an edible oil containing a large amount of linolenic acid having a good flavor and excellent flavor stability and oxidation stability.
[0005]
[Means for Solving the Invention]
In order to achieve the above-mentioned object, the present inventors have intensively studied, and as a result, sesame seeds are mixed and extracted at the same time in the step of producing edible oil from linseed seeds, egoma seeds, perilla seeds, evening primrose seeds or borage seeds, It has been found that an edible oil can be obtained by refining treatment with little deterioration in quality during the treatment process and good flavor and excellent flavor stability and oxidation stability. In the edible oil characterized by flavor, the refining treatment as used in the present invention refers to a treatment mainly comprising a filtration treatment for crude oil obtained by squeezing oil. Examples include sesame oil, nut oil, olive oil. Is mentioned. In the case of edible oils with a low flavor, that is, edible salad oils, etc., it means a treatment through deoxidation, decolorization, and deodorization processes, and if necessary, a dewaxing process is included. Furthermore, the present inventors mixed sesame seeds at the same time in the process of producing edible oil from flaxseed seeds, sesame seeds, perilla seeds, evening primrose seeds or borage seeds, and roasted, squeezed and refined them. It was found that an edible oil with little deterioration and good flavor and excellent flavor stability and oxidation stability can be obtained.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
The present invention will be described in detail below. In the present invention, one or more seeds out of flaxseed, sesame seeds, perilla seeds, evening primrose seeds, and borage seeds from which impurities have been removed are mixed and squeezed with sesame seeds from which impurities have been removed. One or more seeds of linseed seeds, egoma seeds, perilla seeds, perilla seeds, evening primrose seeds, and borage seeds that have been refined to the quality level of edible oils or removed from foreign substances are treated with sesame seeds from which foreign substances have been removed. It is a method for producing edible oil, characterized in that it is mixed, roasted and oiled, and subsequently refined to the quality level of edible oil. In the case of edible oils characterized by flavor, the refining treatment as used in the present invention refers to a treatment mainly based on filtration processing for crude oil obtained by squeezing, and is used for edible oils with low flavor, that is, edible salad oils, etc. In this case, it means a treatment through processes such as deoxidation, decolorization, and deodorization. The mixing ratio of the sesame seeds in the present invention desirably achieves the object of the present invention in the range of 10 to 80% with respect to the selected seeds. When the sesame seed is less than 10%, the flavor stability and storage stability are impaired, and when it is more than 80%, the linolenic acid content intended by the present invention cannot be ensured.
[0007]
The roasting referred to in the present invention means that the seeds are directly or indirectly heat-treated before or after oil extraction, and it is desirable that the heating temperature is 150 to 350 ° C. for 2 to 60 minutes.
[0008]
The seeds containing sesame seeds roasted under such conditions are steamed by a conventional method without being fractionated, and then pressed or squeezed to obtain brown crude oil having a fragrant flavor. This crude oil can be processed only by a filtration step to obtain a final product, and this crude oil can be made a final product through purification steps such as deoxidation, water washing, decolorization and deodorization in the same manner as general vegetable oils and fats.
[0009]
On the other hand, roasted seeds obtained by roasting one or more of flaxseed seeds, egoma seeds, perilla seeds, evening primrose seeds and borage seeds from which impurities have been removed under such conditions were steamed by a conventional method. Then, the final product obtained by mixing and filtering crude oil obtained by squeezing or squeezing the same processed sesame crude oil, or linseed seeds, egoma seeds, perilla seeds, evening primrose from which impurities have been removed After roasting the seeds obtained by roasting one or more seeds or borage seeds under such conditions, the crude oil obtained by subjecting the seeds to steaming or squeezing and extraction is converted into general vegetable oils and fats. Similarly, final products obtained by mixing sesame refined oils, etc., treated in the same way with refined oils obtained through purification steps such as deoxidation, water washing, decolorization, and deodorization, have poor oxidation stability and stable flavor during storage. Poor nature, characteristic over time Takes on the body, there is a hindrance to be used as a cooking oil.
[0010]
The present invention approximates one or more seeds and the shape of the seed among seeds containing many polyunsaturated fatty acids having poor oxidation stability, such as flaxseed seed, egoma seed, perilla seed, evening primrose seed, and borage seed. Simultaneously roasting, oiling and refining one or more seeds and sesame seeds among flaxseed, sesame seeds, perilla seeds, evening primrose seeds and borage seeds It is characterized by doing. Even if one or more seeds are roasted from linseed seeds, sesame seeds, perilla seeds, evening primrose seeds, and borage seeds, and then sesame seeds are roasted separately, both are mixed and oiled. The same effect as when roasting and oiling is obtained. However, when roasting separately, two roasting facilities are required, which is not economical. On the other hand, when each of them is roasted with one roasting facility, it is necessary to roast flaxseed seeds, egoma seeds, perilla seeds, evening primrose seeds, borage seeds or mixed seeds in the latter half, which is unreasonable. . From the viewpoint of efficiency and economy, it is desirable to first mix and roast one or more seeds and sesame seeds among linseed seeds, egoma seeds, perilla seeds, evening primrose seeds, and borage seeds.
[0011]
The fats and oils thus obtained contain linolenic acid in a high concentration, have a good flavor, have excellent flavor and oxidative stability during storage, and can be directly used for food.
[0012]
In the present invention, the storage stability can be further increased by adding an antioxidant such as tocopherol, lecithin, green tea extract, licorice extract and ascorbic acid fatty acid ester to the oil thus obtained.
[0013]
In addition, the edible oil obtained in the present invention and a normal edible oil, that is, edible oil and raw oil such as rapeseed oil, soybean oil, corn oil, wheat germ oil, cottonseed oil, olive oil, safflower oil, sunflower oil, etc. And can be used as food.
