るものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a method for extracting fats and oils from an oil- and fat-containing material, specifically, after crushing the oil- and fat-containing material in an ethanol aqueous solution,
The present invention relates to a method for extracting fats and oils that can be used as raw materials for edible fats and oils from crushed fat-containing substances separated using n-hexane.
油脂は、食品、化粧品素材、脂肪酸工業原料などの幅広
い用途がある。これらの中でも食用油脂としてはその純
度が特に高く、また色相の非常に良いものが望まれる。Oils and fats have a wide range of uses, including food, cosmetic materials, and fatty acid industrial raw materials. Among these, edible oils and fats that have particularly high purity and a very good hue are desired.
従来、油脂含有物からの油脂の抽出は、ｎ−へキサンの
みを用いて行っていたため、色素成分やリン脂質、部分
グリセリド、脂肪酸などの極性成分も同時に抽出されて
いた。したがって、抽出油脂はさらに脱リン、脱酸、ａ
色などの工程が必要であった。Conventionally, fats and oils have been extracted from fat- and oil-containing materials using only n-hexane, and thus polar components such as pigment components, phospholipids, partial glycerides, and fatty acids were also extracted at the same time. Therefore, extracted fats and oils are further dephosphorized, deoxidized, a
Processes such as color were necessary.
このような後工程を設けることは、高純度油脂を工業的
に製造する方法としては、工程上不利であるばかりでな
く、油脂のコスト面でも不利な結果を招くことになる。Providing such a post-process is not only disadvantageous in terms of the process for industrially producing high-purity fats and oils, but also causes disadvantages in terms of the cost of the fats and oils.
このため、溶剤抽出のみで食用油脂原料として使用可能
な高純度油脂が得られればその工業的価値は極めて大き
いものといえる。Therefore, if high-purity fats and oils that can be used as raw materials for edible fats and oils can be obtained by only solvent extraction, their industrial value would be extremely large.
しかるに、このような溶剤抽出によってのみ高純度油脂
を得ることは、油脂の回収率の面と関連して、未だを効
な方法は見い出されていない。たとえば前記極性成分を
抽出可能なエタノールによって油脂含有物を処理したの
ちに、この処理後の上記含有物をｎ−ヘキサンによって
処理して高純度油脂を抽出する方法が考えられているが
、この方法には下記の如き問題がある。However, no effective method has yet been found for obtaining high-purity fats and oils only by such solvent extraction in terms of the recovery rate of fats and oils. For example, a method has been considered in which oil-containing substances are treated with ethanol from which the polar components can be extracted, and then the above-mentioned substances after this treatment are treated with n-hexane to extract high-purity oils and fats. has the following problems.
すなわち、エタノール処理によって前記極性成分を抽出
できてもその際当然かなりの量の油脂が同時に抽出され
、この抽出油脂は酸価が高く、色相も極度に悪いため食
用油脂原料として使用できない部分であり、一方食用油
脂原料として使用可能なｎ−ヘキサンにて抽出される油
脂の量は、上記エタノールにて抽出される油脂の量が多
いために、それだけ少なくなり、高純度油脂の回収率が
大きく減少する点で満足すべきものではなかった。In other words, even if the polar components can be extracted by ethanol treatment, a considerable amount of fats and oils are naturally extracted at the same time, and this extracted fat has a high acid value and an extremely poor color, so it cannot be used as a raw material for edible fats and oils. On the other hand, the amount of fats and oils that can be extracted with n-hexane, which can be used as a raw material for edible fats and oils, decreases because the amount of fats and oils extracted with ethanol is large, and the recovery rate of high-purity fats and oils decreases significantly. It was not satisfactory in that respect.
本発明者らは、鋭意研究の結果、上述したエタノールと
ｎ−ヘキサンとを用いる方法において、親油性を低下さ

は減少し、食用油脂原料として使用可能なｎ−ヘキサン
抽出区分の量が増加することを見い出し、本発明を完成
した。As a result of intensive research, the present inventors found that in the method using ethanol and n-hexane described above, water was added to ethanol to reduce lipophilicity, and after dispersing an oil- and fat-containing substance in the ethanol aqueous solution, By crushing the oil-containing material, the polar components are extracted into an aqueous ethanol solution, and the amount of triglycerides extracted into this fraction is reduced, increasing the amount of the n-hexane extracted fraction that can be used as a raw material for edible fats and oils. The present invention was completed based on this discovery.
すなわち、本発明は、油脂含有物から油脂を抽出する方
法において、油脂含有物をエタノール水溶液に分散させ
た状態で破砕し、つぎに分離した破砕油脂含有物からｎ
−ヘキサンを使用して食用油脂原料として使用可能な油
脂を抽出することを特徴とする油脂の抽出方法に係るも
のである。That is, the present invention provides a method for extracting fats and oils from a fat-and-oil-containing material, in which the fat-and-oil-containing material is crushed in a state in which it is dispersed in an aqueous ethanol solution, and then n.
- This invention relates to a method for extracting fats and oils, which is characterized by using hexane to extract fats and oils that can be used as raw materials for edible fats and oils.

積％、特に好ましくは７０〜８０体積％の範囲にあるこ
とが望ましい。In the present invention, the oil- and fat-containing material is first dispersed in an ethanol aqueous solution and then crushed. It is desirable that it be within the range.
これは、６０体積％より少ないエタノール水溶液では、
破砕した油脂含有物のエタノール水溶液からの分離が困

体積％よりも高いエタノール水溶液では、エタノール水
溶液抽出区分の油脂の量が増加し、ｎ−ヘキサン抽出区
分の油脂の量、つまり食用油脂原料として使用可能な油
脂の量が少なくなるからである。This means that in an ethanol aqueous solution of less than 60% by volume,
This is because it becomes difficult to separate the crushed fat-and-oil-containing material from the ethanol aqueous solution, and the amount of polar lipids such as fatty acids and phospholipids extracted decreases, resulting in a decrease in the quality of the fat and oil in the n-hexane extraction section. In addition, an ethanol aqueous solution of 90
This is because if the ethanol aqueous solution is higher than the volume percent, the amount of fats and oils in the ethanol aqueous solution extraction section will increase, and the amount of fats and oils in the n-hexane extraction section, that is, the amount of fats and oils that can be used as an edible fat and oil raw material, will decrease.
本発明において使用するエタノール水溶液の量は、油脂
含有物１ ｋｇに対し１．０１以上、好ましくは２２以

とエタノール水溶液に抽出される油脂の量が増加して、
ｎ−ヘキサンで抽出される高純度油脂の量が減少するた
め、いずれも好ましくない。The amount of the ethanol aqueous solution used in the present invention is 1.01 or more, preferably 22 or more and 57! The following should be used. If this amount becomes too small, it will be difficult to disperse the oil-containing substances into the ethanol aqueous solution, and conversely, if it is used too much, the amount of fats and oils extracted into the ethanol aqueous solution will increase.
Both are unfavorable because the amount of high-purity fats and oils extracted with n-hexane decreases.
本発明においては、上記の如きエタノール水溶液中で油
脂含有物を破砕したのちろ過し、ケーキとして得られた
破砕油脂含有物をｎ−ヘキサンで処理して、上記含有物
中の高純度油脂を抽出する。In the present invention, the oil-containing substance is crushed in an aqueous ethanol solution as described above, and then filtered, and the crushed oil- and fat-containing substance obtained as a cake is treated with n-hexane to extract high-purity oil- and fat-containing substance. do.
この目的で使用するｎ−ヘキサンの量は、油脂含有物１

ても抽出量は変化せず、回収すべき溶媒の量が増加する
だけ不利となる。The amount of n-hexane used for this purpose is
It is good to set it to 1.0 J or more, preferably 21 or more and 51 or less per kg. If the amount of n-hexane used is too small, it will be difficult to disperse the pulverized fat-containing material in n-hexane, and even if it is used beyond a certain amount, the extraction amount will not change, so it should be recovered. This is disadvantageous as the amount of solvent increases.

とが判る。Above 1. As is clear from the results in Table 2, by adopting the method of the present invention, especially by setting the ethanol content of the ethanol aqueous solution in the range of 60 to 90% by volume, similar results to those of Example 1 can be obtained. It can be seen that high-purity, low-color fats and oils that can be used as raw materials for edible fats and oils can be recovered from the n-hexane extraction section at a higher yield than conventional methods.
