Description
(実施例1)
非イオン性乳化剤としてML−750を用いエマルションを調製した。得られたエマルション中の油滴のメディアン径(体積基準;dp)と乳化剤濃度との関係、及び油分濃度と乳化剤濃度との関係を図2(a)、(b)に示す。尚、(a)は温度220℃、圧力15MPa、(b)は温度230℃、圧力15MPaの条件で行った。ここで、エマルション中の油滴径分布はレーザ回折式粒度分布測定装置を用い、油分濃度はガスクロマトグラフィーを用いて測定した。
(実施例2)
非イオン性乳化剤としてTween20を用いエマルションを調製した。得られたエマルション中の油滴のメディアン径(体積基準;dp)と乳化剤濃度との関係、及び油分濃度と乳化剤濃度との関係を図4に示す。この図4から前記実施例1と同様に、低乳化剤濃度でメディアン径dpが90nm程度の極めて均質なエマルションが得られることが分る。前記実施例と異なるのはTween20の濃度が濃くなると、dpが大きくなる点であるが、原因は不明である。
(実施例3)
イオン性乳化剤としてSDS(ドデシル硫酸ナトリウム)を用いエマルションを調製した。得られたエマルション中の油滴のメディアン径(体積基準;dp)と乳化剤濃度との関係、及び油分濃度と乳化剤濃度との関係を図5に示す。この図5から明らかなように、イオン性乳化剤を用いた場合には何れの濃度においても非イオン性乳化剤を用いた場合と比較してdpは数〜20μmと大きくなってしまうことが分る。
Claims (3)
- 脂肪酸、高級アルコールまたは油脂と水とを温度を170℃以上、圧力を1MPa以上とした雰囲気で接触せしめることで水に脂肪酸または油脂を溶解せしめ、この脂肪酸または油脂を溶解した水溶液に非イオン性乳化剤を共存させるとともに当該水溶液を冷却することで、分散相を脂肪酸または油脂とし連続相を水としたエマルションとすることを特徴とするエマルションの作製方法。
- 請求項1に記載のエマルションの作製方法において、前記乳化剤の添加時期は水に脂肪酸または油脂を溶解せしめた後に行うことを特徴とするエマルションの作製方法。
- 請求項1または請求項2のいずれかに記載の方法にて得られたエマルションであって、分散相粒子の平均メディアン径が100nm以下であることを特徴とするエマルション。
