Description

本発明は、吸油低減剤、吸油低減方法および揚げ物用油脂組成物に関する。   The present invention relates to an oil absorption reducing agent, an oil absorption reducing method, and an oil and fat composition for deep-fried food.

揚げ物は、加熱した食用油脂を用いて調理される食品である。揚げ物には、天ぷら、コロッケ、唐揚げ等がある。食用油脂を用いて調理される際に、調理対象物中の水分と食用油脂との置換等により、該食用油脂が揚げ物へ移行する。   Fried food is a food that is cooked using heated edible fats and oils. Deep-fried food includes tempura, croquettes, and deep-fried food. When cooking using edible fats and oils, the edible fats and oils are transferred to fried foods by replacing the moisture in the cooking object with the edible fats and oils.

近年、消費者の健康志向に伴い、揚げ物に含まれる油脂量を低減させることが課題の一つとされている。例えば、特許文献1(特開2015−119665)には、油脂に特定の乳化剤を0.02〜0.08質量%配合した加熱調理用油脂組成物が加熱調理後の調理対象物に残存する油分を低減することができることが開示されている。特定の乳化剤として、コハク酸モノオレイン酸グリセリン、クエン酸モノオレイン酸グリセリン、ポリオキシエチレンソルビタンモノオレエート、ショ糖エルカ酸エステル、及び構成する脂肪酸の47質量%以上が多価不飽和脂肪酸である脂肪酸モノグリセリドについて、その効果が開示されている。   In recent years, it has been considered as one of the problems to reduce the amount of fats and oils contained in deep-fried foods with the consumer health orientation. For example, in Patent Document 1 (Japanese Patent Application Laid-Open No. 2015-119665), an oil component in which a fat and oil composition for cooking that contains 0.02 to 0.08% by mass of a specific emulsifier is mixed in the fat and oil remains in the cooking object after cooking. It is disclosed that can be reduced. As specific emulsifiers, glycerin succinate monooleate, glycerol citrate monooleate, polyoxyethylene sorbitan monooleate, sucrose erucic acid ester, and 47% by mass or more of the constituent fatty acids are polyunsaturated fatty acids The effects are disclosed for fatty acid monoglycerides.

一方、特許文献2(特開2009−55897)には、「精製された食用油脂に、原油および中間的油脂から選ばれる少なくとも一種のリン由来成分をリン分が0.1〜10.0ppmとなるように添加することを含む、180℃での加熱耐性に優れた揚げ物用油脂組成物の製造方法」が開示されている。この発明によれば、食用油脂の加熱時に起こる着色および加熱臭を抑制できるとされる。しかしながら、該原油および該中間的油脂に揚げ物の吸油低減の効果があることについては、示唆も開示もされていない。   On the other hand, Patent Document 2 (Japanese Patent Application Laid-Open No. 2009-55897) states that “the refined edible oil / fat contains at least one phosphorus-derived component selected from crude oil and intermediate oil / fat and the phosphorus content is 0.1 to 10.0 ppm. The manufacturing method of the oil-fat composition for deep-fried foods which was excellent in the heat tolerance in 180 degreeC including addition in this way is disclosed. According to this invention, it is said that the coloring and heating odor which occur at the time of heating of edible fats and oils can be suppressed. However, there is no suggestion or disclosure that the crude oil and the intermediate fats and oils have an effect of reducing oil absorption of fried foods.

本発明の吸油低減剤の有効成分である粗精製油は、油糧原料から得られる原油の精製工程において、脱酸工程を経ていないことを特徴とする。精製された食用油脂は、通常、油糧原料を圧搾抽出および/または溶剤抽出による搾油で得られる原油を、脱ガム工程→脱酸工程→脱色工程→脱臭工程の順に精製されて、不純物が除かれる。工程の操作である「脱ガム処理」、「脱酸処理」、「脱色処理」、及び「脱臭処理」は、公知であり、本発明はこれらの処理を特に制限なく使用可能である。前記粗精製油は、好ましくは脱臭工程を経たものであり、さらに好ましくは脱ガム工程および脱臭工程を経たものであり、さらにより好ましくは脱ガム工程、脱色工程および脱臭工程を経たものである。   The crude refined oil, which is an active ingredient of the oil absorption reducing agent of the present invention, is characterized in that it has not undergone a deoxidation process in a refinement process of crude oil obtained from an oil feedstock. Refined edible fats and oils are usually refined in the order of degumming step → deoxidation step → decolorization step → deodorization step from crude oil obtained by oil extraction by oil extraction and / or solvent extraction. It is burned. “Degumming treatment”, “deoxidation treatment”, “decoloration treatment”, and “deodorization treatment” which are process operations are known, and the present invention can use these treatments without any particular limitation. The crudely refined oil is preferably subjected to a deodorizing step, more preferably subjected to a degumming step and a deodorizing step, and still more preferably subjected to a degumming step, a decoloring step and a deodorizing step.

以下に、脱ガム処理、脱酸処理、脱色処理、及び脱臭処理を概説する。
脱ガム工程(脱ガム処理)とは、油分中に含まれるリン脂質を主成分とするガム質を水和除去する工程である。脱ガム工程の処理条件は、特に制限されず、汎用の条件を使用可能である。例えば、水の使用量は、原料油脂に対して、通常、1〜5質量%、好ましくは1.5〜3質量%である。適宜、シュウ酸、クエン酸、リン酸等の有機酸の水溶液からなる脱ガム剤を添加してもよい。脱ガム温度は、通常、40〜95℃でよく、好ましくは60〜95℃である。原油に水蒸気又は水を加えて攪拌することにより、ガム質が水和して水溶性となり、水層へ移る。撹拌時間は、通常、1〜60分である。この水層は遠心分離機等で分離される。
Below, a degumming process, a deoxidation process, a decoloring process, and a deodorizing process are outlined.
The degumming step (degumming treatment) is a step of hydrating and removing a gum having phospholipids contained in the oil as the main component. The treatment conditions for the degumming step are not particularly limited, and general-purpose conditions can be used. For example, the usage-amount of water is 1-5 mass% normally with respect to raw material fats and oils, Preferably it is 1.5-3 mass%. If appropriate, a degumming agent comprising an aqueous solution of an organic acid such as oxalic acid, citric acid, phosphoric acid or the like may be added. The degumming temperature may usually be 40 to 95 ° C, preferably 60 to 95 ° C. By adding water vapor or water to the crude oil and stirring, the gum is hydrated and becomes water-soluble and moves to the water layer. The stirring time is usually 1 to 60 minutes. This aqueous layer is separated by a centrifuge or the like.

脱酸工程(脱酸処理)とは、炭酸ナトリウムや苛性ソーダといったアルカリの水溶液で処理することにより油分中に含まれる遊離脂肪酸をセッケン分として除去する工程である。脱酸工程の処理条件は、特に制限されず、汎用の条件を使用可能である。例えば、濃度が3〜40質量%のアルカリ水溶液を、原料油脂に対して、通常、0.1〜5質量%、好ましくは0.5〜3質量%となるように添加する。脱酸温度は、通常、20〜120℃でよく、好ましくは35〜95℃である。油脂に不溶の上記セッケンは、遠心分離機等で分離される。脱酸工程(脱酸処理)は、アルカリを用いない物理的精製法でもよい。物理的精製法には、水蒸気蒸留法や分子蒸留法がある。分子蒸留法では、一部の脱臭処理も同時に行われる。   The deoxidation step (deoxidation treatment) is a step of removing free fatty acids contained in the oil as soap by treating with an alkaline aqueous solution such as sodium carbonate or caustic soda. The treatment conditions for the deoxidation step are not particularly limited, and general-purpose conditions can be used. For example, an alkaline aqueous solution having a concentration of 3 to 40% by mass is usually added so as to be 0.1 to 5% by mass, preferably 0.5 to 3% by mass with respect to the raw material fat. The deoxidation temperature may usually be 20 to 120 ° C, preferably 35 to 95 ° C. The soap insoluble in fats and oils is separated by a centrifuge or the like. The deoxidation step (deoxidation treatment) may be a physical purification method that does not use an alkali. Physical purification methods include steam distillation and molecular distillation. In the molecular distillation method, part of the deodorizing treatment is also performed.

脱色工程(脱色処理)とは、油分中に含まれる色素を活性白土、活性炭等へ吸着させて除去する工程である。脱色工程の処理条件は、特に制限されず、汎用の条件を使用可能である。例えば、活性白土の使用量は、原料油脂に対して、通常、0.05〜5質量%でよく、好ましくは0.1〜3質量%である。脱色温度は、通常、70〜120℃でよく、好ましくは80〜120℃である。脱色工程は、通常、無水下で行われるが、水の存在下で行ってもよい。脱色時間は、通常、5〜120分間、好ましくは10〜80分間である。色素の付着した活性白土等は、減圧濾過等により除去される。   The decoloring step (decoloring treatment) is a step of removing the pigment contained in the oil by adsorbing it on activated clay, activated carbon or the like. The treatment conditions for the decolorization step are not particularly limited, and general-purpose conditions can be used. For example, the amount of the activated clay used may normally be 0.05 to 5% by mass, preferably 0.1 to 3% by mass, based on the raw material fat. The decolorization temperature may usually be 70 to 120 ° C, preferably 80 to 120 ° C. The decolorization step is usually performed under anhydrous conditions, but may be performed in the presence of water. The decoloring time is usually 5 to 120 minutes, preferably 10 to 80 minutes. The activated clay with the pigment attached is removed by vacuum filtration or the like.

脱臭工程(脱臭処理)とは、減圧下で水蒸気蒸留等することによって油分中に含まれる有臭成分を除去する工程である。脱臭工程の処理条件は、特に制限されず、汎用の条件を使用可能である。例えば、水蒸気の使用量は、原料油脂に対して、通常、0.1〜10質量%、好ましくは0.3〜8質量%である。水蒸気蒸留の温度は、通常、200〜260℃、好ましくは220〜250℃である。減圧度は、温度に依存するが、通常、150〜1000Pa、好ましくは200〜800Paである。また、蒸留時間は、温度及び減圧度に依存するが、通常、10〜180分間、好ましくは20〜120分間である。   The deodorizing step (deodorizing treatment) is a step of removing odorous components contained in the oil by steam distillation or the like under reduced pressure. The treatment conditions for the deodorization step are not particularly limited, and general-purpose conditions can be used. For example, the usage-amount of water vapor | steam is 0.1-10 mass% normally with respect to raw material fats and oils, Preferably it is 0.3-8 mass%. The temperature of the steam distillation is usually 200 to 260 ° C, preferably 220 to 250 ° C. The degree of vacuum depends on the temperature, but is usually 150 to 1000 Pa, preferably 200 to 800 Pa. Moreover, although distillation time is dependent on temperature and a pressure reduction degree, it is 10 to 180 minutes normally, Preferably it is 20 to 120 minutes.
