Conditions to Prolonged Release of Microencapsulated Carvacrol on Alginate Films as Affected by Emulsifier Type and PH

Figure 2

Characterization of each film at initial time at different pH: (a) variation of color (CIEDE2000), (b) opacity, (c) molecular mobility by FID, and (d) contact angle. Bars correspond to standard deviation of mean value. 0.25% T: 0.25% w/w trehalose; 0.75% T: 0.75% w/w trehalose; T 20: 1% w/w Tween 20.
