- the reaction solution is distilled by a known method so as to separate fatty acid esters and the like from fats and oils.
- raw fats and oils and raw fatty acid esters and the like are selectively retained in the steaming step before the final stage.
- the distillation conditions are as follows. Specifically, the distillation is set so that the fatty acids or the esters thereof released from the raw material triglycerides are kept as much as possible, and that only the raw material fats and oils and the raw material fatty acid esters remain substantially selectively and in large amounts. Is good.
- This temperature is lower than the temperature at which all fatty acid esters and the like are distilled, especially at 210, and preferably the following temperature. This allows the removal of undesirable by-products such as high melting point components due to migration of triglycerides and diglycerides. Generation is suppressed. In addition, since the heat history becomes small, deterioration of color tone and deterioration of oxidation deterioration stability can be suppressed. These effects become clearer as the length of fatty acids such as fatty acid esters to be introduced is longer, and is most remarkable when the length is 22 or more (22 to 24).
- Distillation is completed when most of the fatty acid ester and the like released from the triglyceride are distilled off.After the distillation, the liquid is left as it is, or if necessary, a raw material fatty acid ester or the like is added thereto and brought to a temperature suitable for the reaction.

- reaction substrate was prepared.
- the column was filled with 90 g of the above lipase agent, and the reaction substrate was passed through at 50 gZhr, 53, and the reaction solution was collected to obtain the first-stage reaction solution. Hold in a distillation flask under 2T0RR vacuum at 206 to selectively remove the forehead (51.4 parts) until substantially no ethyl oleate remains.
- Table 1 shows the fatty acid composition of the ester before distillation, the distillate, and the ester remaining in the flask.
- Example 1 50 parts of trilaurin (98% purity, manufactured by Sigma) and 50 parts of stearic acid were mixed, and the same procedure as in Example 1 was performed.
- the column temperature was set to 65 using Lipozyme (enzyme manufactured by Novo)
- the column was filled with 5 g of the lipase agent, and the substrate was passed at 3 gZhr.
- the mixture was held in a distillation flask at 150 under 2 TORR vacuum to remove lauric acid.
- Example 2 After distilling the first-stage reaction solution of Example 1 at 255 to completely remove the ethyl ester, 72 parts of behenic acid ethyl ester was added to 28 parts of the triglyceride remaining in the flask, and the mixture was treated with clay. The solution was passed to obtain a second-stage reaction solution, which was held at 255 under 2T0RR vacuum to completely remove the ester component.
- the BOB content in this reaction product was 62%, but the BBB content was as high as 5.1%, making it difficult to use as a tempering accelerator unless the high melting point component was separated and removed. . In addition, it was considerably colored and was not preferable (color tone-5.0 x 50).
- the first-stage distillation was carried out at 235, and the same method as in Example 2 was carried out except that 70 parts of oleic acid ethyl ester newly added to the S solution were used.
- the Example requires less amount of fatty acid esters and the like than the Comparative Example, suppresses the generation of by-products, and improves the commercial portability of the target triglyceride as compared with the ordinary multistage transesterification method. And was able to do it efficiently.

Abstract
A method of transesterifying fat or oil for the purpose of modifying the same and efficiently preparing target triglycerides in high concentrations. The method comprises the step of transesterifying a fat or oil with a fatty acid or a lower alcohol ester thereof in the presence of an enzyme catalyst and the step of distilling off the acid or the ester from the reaction mixture, these two steps being repeated in a number of stages, which method is characterized by leaving the fat or oil and the feedstock fatty acid or ester thereof selectively in the distillation steps preceding the one in the final stage to remain unremoved in the reaction mixture. This method serves to reduce the amount of the fatty acid or the ester to be used, to inhibit the formation of by-products, and to provide the target triglycerides in high concentrations more efficiently than the conventional multistage transesterification methods.

(課題を解決するための手段) (Means for solving the problem)
本発明者は種々のエステル交換反応方法について鋭意研究した結果、 多段エステル交换 において脂肪酸エステル等の全てを留去してしま う従釆の蒸留方法を改め、 反応によってトリグリセリ ドから遊離してく る脂肪酸エステル等の沸点がトリグリセリ ドに導入すべき原料脂肪酸ェ ステル等の沸点より小さい場合は、 反応によってトリグリセリドから遊 維してくる脂肪酸エステル等は留去するが、 トリグリセリ ドに導入すベ き原料脂肪酸エステル等が留去されないような蒸留を行うことによって 、 分別を行わなくても目的とする トリグリセリ ドの髙濃度化を効率良く 達成できるという知見を得、 本発明を完成させるに至った。 As a result of intensive studies on various transesterification methods, the present inventors have revised the conventional distillation method in which all fatty acid esters and the like are distilled off in a multi-stage transesterification, and the fatty acids liberated from triglycerides by the reaction were revised. If the boiling point of the ester etc. is lower than the boiling point of the starting fatty acid ester etc. to be introduced into the triglyceride, the fatty acid ester etc. which is released from the triglyceride by the reaction is distilled off, but the starting fatty acid to be introduced into the triglyceride The present inventors have found that by performing distillation such that esters and the like are not distilled off, it is possible to efficiently achieve the desired triglyceride concentration reduction without fractionation, thereby completing the present invention.
すなわち、 本発明は、 油脂を脂肪酸又はその低級アルコールエステル

And a step of transesterifying as a catalyst with an enzyme, and a distillation step of removing fatty acids or lower alcohol esters thereof, in a multi-stage process.袖 This is a method of exchanging sleeve fat by using alcohol as a threat to selectively remain.
原料油脂及び原料脂肪酸エステル等の種類は一定の制約を受ける。 す なわち、 蒸留工程において原料脂肪酸エステル等は暂去せずに、 原料油 脂から遊離する脂肪酸エステル等をできるだけ選択的に留去できるよう な原料の組合せを選択しなければならない。 従って、 一般的には^に よってトリグリセリ ドから遊離してくる脂肪酸またはそのエステルの沸 点がトリグリセリ ドに導入すべき原料脂肪酸エステル等の沸点より小さ くなるように選択する必要がある。 The types of raw material fats and oils and raw material fatty acid esters are subject to certain restrictions. That is, a combination of raw materials must be selected so that fatty acid esters and the like liberated from the raw material oil can be selectively removed as much as possible without removing the raw material fatty acid ester and the like in the distillation step. Therefore, in general, it is necessary to select such that the boiling point of the fatty acid or its ester released from the triglyceride by ^ is lower than the boiling point of the raw material fatty acid ester to be introduced into the triglyceride.
以上の制約の他は特に限定されるものではなく、 種々のものを使用す ることができる。 具体的に油脂としては、 ひまわり油、 ハイォレイツク ひまわり油、 サフラワー油、 ハイォレイツクサフラワー油、 ^ :油、 ナ タネ油、 ォリーブ油、 パー厶油、 サル脂、 シァ脂、 ヤシ油、 パーム核油 等の植物油、 魚油、 牛脂、 豚脂等の動物油から選ばれる 1種または 2種 以上の混合油、 並びに M C Tやトリラウリン等の合成グリセリ ドが例示 でき、 脂肪酸エステル等としてはパルミチン酸、 ォレイン酸、 ベヘン酸 など炭素数 1 2〜 2 4の脂肪酸及びこれらのメチルまたはェチルエステ ル等のような低极アルコールのエステルが例示できる。 Other than the above restrictions, there is no particular limitation, and various types can be used.

以上の原料を使用して酵素を触媒としてエステル交換反応を行う。 ェ ステル交換方法は公知の方法を採用することができる。 すなわち、 リバ ーゼ等のエステル交換活性を有する酵素又は菌体を公知の方法によって
固定化した酵素製剤を触媒として使用することができる。 A transesterification reaction is carried out using the above-mentioned raw materials and using an enzyme as a catalyst. As the ester exchange method, a known method can be adopted. That is, an enzyme or a cell having transesterification activity such as ribose is converted by a known method. The immobilized enzyme preparation can be used as a catalyst.
反応液は脂肪酸エステル等を油脂から分雜するように公知の方法で蒸 留するが、 この発明では最終段よりも前の蒸 ¾工程において原料油脂及 ぴ原料脂肪酸エステル等は ¾択的に残留するような蒸留条件で行う。 具 体的には、 原料トリグリセリ ドから遊離してくる脂肪酸またはそのエス テルをできるだけ留まし、 実質的に原料油脂及び原料脂肪酸エステル等 のみが選択的かつ多量に残留するように蒸留 を設定するのがよい。 The reaction solution is distilled by a known method so as to separate fatty acid esters and the like from fats and oils. In the present invention, raw fats and oils and raw fatty acid esters and the like are selectively retained in the steaming step before the final stage. The distillation conditions are as follows. Specifically, the distillation is set so that the fatty acids or the esters thereof released from the raw material triglycerides are kept as much as possible, and that only the raw material fats and oils and the raw material fatty acid esters remain substantially selectively and in large amounts. Is good.
この温度は全脂肪酸エステル等を蒸留する温度よりも低い温度、 特に 2 1 0で以下の温度がよく、 このことによってトリグリセリ ド及びジグ リセリ ドのマイグレーションによる高融点成分などの好ましくない副生 物の生成が抑えられる。 また、 熱履歴が小さくなるため色調の劣化、 酸 化劣化安定性の低下も抑えられる。 これらの効果は導入しょうとする原 科脂肪酸エステル等の脂肪酸の錤長が長い程、 明瞭にあらわれ、 特に該 錤長が 2 2以上 (2 2〜 2 4 ) のとき最も顕著である。 This temperature is lower than the temperature at which all fatty acid esters and the like are distilled, especially at 210, and preferably the following temperature. This allows the removal of undesirable by-products such as high melting point components due to migration of triglycerides and diglycerides. Generation is suppressed. In addition, since the heat history becomes small, deterioration of color tone and deterioration of oxidation deterioration stability can be suppressed. These effects become clearer as the length of fatty acids such as fatty acid esters to be introduced is longer, and is most remarkable when the length is 22 or more (22 to 24).
トリグリセリ ドから遊離してくる脂肪酸ェステル等の大部分を留去し たところで蒸留を終え、 蒸留後の 、液をそのまま、 又はこれに必要に 応じ原料脂肪酸エステル等を加え、 反応に適した温度にして次段のエス テル交換反応と蒸留を行う。 より高港度のトリグリセリ ドを得たい場合 は、 必要に応じ段数を増やす (さらにエステル交換反応〜蒸留を操り返 す) こともできる。 Distillation is completed when most of the fatty acid ester and the like released from the triglyceride are distilled off.After the distillation, the liquid is left as it is, or if necessary, a raw material fatty acid ester or the like is added thereto and brought to a temperature suitable for the reaction. To conduct the next step of ester exchange reaction and distillation. If a higher port triglyceride is desired, the number of stages can be increased as needed (further transesterification to distillation is repeated).
最終段の反応後は通常の蒸留によつて実質的に全部の脂肪酸エステル 等を除去し、 目的とするトリグリセリ ドを得る。 After the reaction in the final stage, substantially all fatty acid esters and the like are removed by ordinary distillation to obtain the desired triglyceride.
以上の一連の方法により、 原料脂肪酸エステル等の反応効率を増大さ せ、 目的とするトリグリセリ ドの高漉度化を効率良く行うことができる
。 しかも、 本発明は、 溶剤分別等の油脂の分別工程を付加する必要がな いので、 安全性の観点からも便れた方法といえる。 実施例及び比校例 By the above series of methods, the reaction efficiency of the raw material fatty acid ester and the like can be increased, and the target triglyceride can be efficiently filtered. .
