Description
本発明は、天然のエステル化油脂からカロチン、ユビキノンおよびリン脂質などのカロチン濃縮物を回収する方法に関し、また特に、限定されるものではないが、粗パーム油およびパーム油製品を含む。
粗パーム油ならびに脱ガム・漂白したパーム油のエステル化/エステル交換は、遊離脂肪酸およびアシルグリセロールをアルキルエステルリッチ層へ変換するのに十分な条件下でアルカリ性触媒の存在下、アルキルアルコールを用いて行い、もう一度再エステル交換を行うか、清浄な水で洗浄して中和する。エステル化したパーム油には一段または多段の減圧蒸留を行う。
第一段の減圧蒸留から得られたカロチンリッチアルキルエステル層を濾過するかまたは炭化水素溶剤で処理してモノアシルグリセロールを除去する。この濾液に対して二次減圧蒸留を行ってカロチン濃縮物を製造する。
次の減圧蒸留の前には最小量のパーム油エチルエステルを、処理したカロチンリッチアルキルエステル(この場合メチルエステル)に加える。生成されたカロチン濃縮物はリン脂質を含むジアシルグリセロール中にユビキノンをリッチに含む。さらに精製するには、疎水性および親水性溶媒を用いてカロチン濃縮物の処理を行う。所望のカロチン画分濃縮物を得るために濃縮物を鹸化してもよい。油をアルキルエステルへ変換する前に粗パーム油を膜濾過することでリン脂質も回収される。
