The amount of resin used is determined by the amount of anion in the liquid to be treated, that is, the total molar equivalent of contaminants (amino acids, organic acids, chloride ions, etc.) contained in the solution in addition to shikimic acid. It suffices to keep it within the exchange capacity.
本発明における、 アルカリ処理を行ったシキミ酸を含む発酵液、 除菌液、 脱色 液、 その他シキミ酸含有液を樹脂処理する場合の好ましい態様は以下の通りであ る。  In the present invention, preferred embodiments in the case where a fermentation solution, a disinfecting solution, a decolorizing solution, or another solution containing shikimic acid containing shikimic acid which has been subjected to an alkali treatment are treated with a resin are as follows.

The pH of the liquid to be treated during the passage is from neutral to alkaline, at a temperature of 90 ° C. or less, and SV (space velocity) = 1 to 5, preferably 3 = 1 to 3, to absorb shikimic acid. After adsorption, pure water is passed through 1 to 5 RV (resin capacity) to remove sugars and other impurities that do not adsorb to the resin.
次に、 樹脂に吸着したシキミ酸を溶離する。 シキミ酸の溶離には、 酸性水溶液 あるいは強アル力リ性水溶液を溶離剤として用いることが可能である。 好ましい 溶離剤としては、 0.4~ 1.0Nの塩酸、 0. 1〜2 Nの酢酸水溶液、 0.2〜 1.

For elution of shikimic acid, it is possible to use an acidic aqueous solution or a strong aqueous solution as an eluent. Preferred eluents include 0.4 to 1.0 N hydrochloric acid, 0.1 to 2 N aqueous acetic acid, and 0.2 to 1. ON aqueous NaOH. It is preferable to pass these eluents at SV = 1 to 5, preferably SV = 1 to 3, to elute shikimic acid. However, when separating from decomposed and / or related compounds other than dehydroshikimic acid, use acetic acid (preferably 1 to 2N) and a strongly alkaline aqueous solution as the eluent. In particular, an NaOH aqueous solution (preferably from 0.4 to 1. ON) and a water-oxidizing realm (KOH) aqueous solution (preferably from 0.4 to 1. ON) are preferable. FIG. 2 shows an HPLC analysis chart of the shikimic acid fraction in each eluent (the analysis method will be described later in Example 1).
NaOH水溶液や KOH水溶液などの強アルカリ性水溶液で溶離した場合、 陽 イオンを除去するために、 塩酸などで H型に調整した強酸性カチオン交換樹脂な どに通液し脱塩を行う方が良い。 シキミ酸含有貫流液を減圧濃縮後、 冷却晶析を 行うことによりシキミ酸結晶を得ることができる。 その他通常の濃縮方法及び晶 析方法が適用可能である。  When eluting with a strong alkaline aqueous solution such as NaOH aqueous solution or KOH aqueous solution, desalting is preferably performed by passing the solution through a strong acidic cation exchange resin adjusted to H-type with hydrochloric acid or the like to remove cations. The shikimic acid crystal can be obtained by concentrating the shikimic acid-containing flow-through liquid under reduced pressure and performing cooling crystallization. Other usual concentration methods and crystallization methods can be applied.
—方、 酢酸水溶液で溶離した場合、 そのまま溶離液を減圧濃縮し、 冷却晶析を 行うことにより、 シキミ酸結晶を得ることができる。 もちろん、 その他通常の濃 縮方法及び晶析方法も適用可能である。  On the other hand, when eluting with an acetic acid aqueous solution, the eluate is directly concentrated under reduced pressure, and then cooled and crystallized, whereby shikimic acid crystals can be obtained. Of course, other ordinary concentration methods and crystallization methods are also applicable.
また、 上記のアルカリ処理と陰イオン交換樹脂吸着は、 NaOHなどで OH型 に再生した樹脂へ吸着することにより同時に行うことができる。 即ち、 NaOH 水溶液などの強アル力リ性水溶液を用いて OH型に調整した陰イオン交換樹脂に、 シキミ酸濃度 1〜 10 g/Lに調整したシキミ酸含有液を通液する。 この通液に より、 アルカリ処理と樹脂吸着を同時に行うことが可能である。 通液後、 純水を 1〜3RV通液した後、 前述と同じく、 酸性水溶液あるいは強アルカリ性水溶液 を溶離剤として用いて、 シキミ酸を溶離する。 溶離後の処理は、 前述の通りであ る。  Further, the alkali treatment and the adsorption of the anion exchange resin can be performed simultaneously by adsorbing the resin regenerated to the OH type with NaOH or the like. That is, a shikimic acid-containing liquid adjusted to a shikimic acid concentration of 1 to 10 g / L is passed through an anion exchange resin adjusted to OH type using a strong aqueous solution such as an aqueous NaOH solution. By this passage, alkali treatment and resin adsorption can be performed simultaneously. After passing the solution, pure water is passed through 1-3 RV, and shikimic acid is eluted using an acidic aqueous solution or a strongly alkaline aqueous solution as an eluent as described above. The treatment after elution is as described above.
