	Thermodynamic and kinetic aspects of the transport of small molecules in dispersed systems
		ethyl acetate, ethyl butanoate and ethyl hexanoate, were studied in simple and multiphase systems.
		The transfer of ethyl acetate through the interface was the rate-limiting step, while the transfer of ethyl butanoate and ethyl hexanoate through the oil was limited by the diffusion in the aqueous phase.
		The effect of sodium caseinate is different for the less hydrophobic compound (ethyl acetate) and the more hydrophobic compounds (ethyl butanoate and ethyl hexanoate); in the presence of sodium caseinate, the R"a"q value increases for ethyl acetate, while the R"I value increases for ethyl butanoate and ethyl hexanoate.

	Effect of Interface in Model Food Emulsions on the Volatility of Aroma Compounds (Site not responding. Last check: 2007-10-25)
		Volatility of two aroma compounds-ethyl butanoate and ethyl hexanoate-was investigated in monophasic and biphasic systems.
		In homogeneous systems, aroma retention was affected by the nature of the nonvolatile compounds: it was nearly 100% in triolein for both ethyl butanoate and ethyl hexanoate; in 5 g/L aqueous solution of sodium caseinate or sucrose stearate, retention values were 20% and 35% for ethyl butanoate and ethyl hexanoate, respectively.
		In biphasic systems, the vapor-liquid partition coefficient of ethyl hexanoate was not changed whether or not the system was emulsified and regardless of the nature of the surface active compound, i.e., sodium caseinate or sucrose stearate.

		Calculation of odor activity values (ratio of concentration to odor threshold), on the basis of odor thresholds in water, revealed especially the six compounds (Z)-3-hexenal (green), 4-hydroxy-2,5-dimethyl-3(2H)-furanone (caramel-like, sweet), methyl butanoate (fruity), ethyl butanoate (fruity), methyl 2-methylpropanoate (fruity), and 2,3-butanedione (buttery) as the key flavor compounds in the typical strawberry-like odor of the juice.
		These results were corroborated by the following sensory experiments: A mixture of the 12 most potent odorants added to a model juice matrix, consisting of pectin, sugars, and nonvolatile acids, in concentrations equal to those in the fresh juice, resulted in an overall odor profile very similar to that of the fresh juice.
		Furthermore, comparison of the overall odors of 11 model mixtures lacking in 1 of the 12 odorants under investigation, with the odor evoked by the complete set of odorants, showed a clear flavor difference, especially when 4-hydroxy-2,5-dimethyl-3(2H)-furanone, (Z)-3-hexenal, or methyl butanoate was lacking in the mixture.
