2.2. Preparation of emulsions
The emulsions were prepared by the dispersion of 2 or 5 wt% of the emulsifier (soy lecithin or Tween 80) in the oil phase and then addition of the aqueous phase. The ingredients were then mechan- ically stirred (4000 or 9000 rpm) in glass vessel with a volume of 250 mL, using a Silverson L4RT homogenizer (Silverson Machines Ltd, UK), during 3 min at 20 °C. The emulsions were prepared rang- ing from 70 to 90 vol.% of oil phase.
The initial emulsions were O/W and the inverted ones were W/O.

2.2. Emultsioak prestatzea
emultsioak 2 edo 5 wt du emultsionatzailea (soja-lezitina edo bitarteko 80) olio-fasean dauden guztien% sakabanaketa eta, ondoren, ur-fasea gain formulatu zituzten. Osagaiak orduan mekanismo ically zirikatu zituzten (4000 edo 9000 rpm) kristalezko ontzi batean 250 ml bolumena, 20 º C-tan bat Silverson L4RT homogeneizatzaile (Silverson Makinak SL, Erresuma Batua), erabiliko 3 min zehar. Emultsioak prestatu ziren rang- 70 90 vol. Olio-fasea% to ing.
Hasierako emultsioak O / W ziren eta alderantzizko zitezkeenak W / O.
