(1)W/O型エマルションの製造
表1のW/Oに示した成分を使用した(表中の量は重量部を示す)。内水相成分を油相成分に混合し、高圧ホモジナイザー(1000kg/cm2)で乳化してW/O型エマルションを製造した。
(2)W/O/W型エマルションの製造
(1)で製造したW/O型エマルションを外水相成分に混合し、プロペラ攪拌機を用いて250rpmで10分間撹拌し、W/O/W型エマルションを製造した。
(3)外観安定性試験及び漏洩試験
(2)で得られたサンプルについて以下の方法で外観安定性試験及び漏洩試験を行った。試験は各サンプルの製造直後(初期)及び40℃3ヶ月放置後に行った。結果を表1に示す。
外観安定性試験
外観安定性試験は、目視による外観観察(オイル浮き)及び顕微鏡観察(エマルション粒子の観察)を行い、以下の基準により評価した。
◎:オイル浮きが全くなく、W/O/W型エマルションの合一や崩壊が認められない
○:オイル浮きはないが、W/O/W型エマルションの一部について合一又は崩壊が認められる
△:オイル浮きがややあり、W/O/W型エマルションの一部について合一について又は崩壊が認められる
×:オイル浮きがかなりあり、W/O/W型エマルションのほとんどについて合一又は崩壊が認められる
漏洩試験
各サンプルにリン酸を加えてpH2に調整した後、遠心分離(1000rpm、5分間)を行って外水相とW/Oエマルション相を分離させて外水相を分取し、分取した外水相の色差(A値)を色差計(Color Meter ZE2000(日本電色工業(株)製)により測定した。一方、外相中に食用黄色5号が全量漏洩した場合のモデルとして、表1中の外水相成分(全70重量部)に、エマルションと同量の食用黄色5号(0.001重量部)を溶解した溶液の色差(B値)を測定した。A値とB値を使用し、下記数式により漏洩率を測定し、漏洩率を使用して下記評価基準により評価した。
評価基準
◎:漏洩率が10%未満
○:漏洩率が50%未満
×:漏洩率が50%以上
(4)総合評価
(3)の外観安定性試験及び漏洩試験結果を用いて下記評価基準により総合評価を行った。
◎:評価結果に×が無く、◎が3個以上
○:評価結果に×が無く、◎が1または2個
×:評価結果に×がある
表2〜4に示した成分を使用して、実施例1と同様の方法でW/O/W型エマルションを製造した。得られた各サンプルについて、実施例1と同様の方法で、外観安定性試験及び漏洩試験を行い、その結果に基づき総合評価を行った。結果を表2〜4に示す。なお、サンプル2−1〜2−15ではオイルとして25℃で液体の分岐または不飽和脂肪酸エステルを使用し、2−16〜2−21ではオイルとして直鎖脂肪酸エステル、炭化水素、25℃で固体の脂肪酸エステルなどを使用している。
