ExGA: microencapsulated hop extract with Arabic gum; ExMD-GA: microencapsulated hop extract with mixture of maltodextrin and Arabic gum; ExMD: microencapsulated hop extract with maltodextrin. Data reported in parenthesis are loss percentages with respect to the initial content. Data in rows with different lowercase letters are statistically different at p level < 0.05. Data in columns with different capital letters are statistically different at p level < 0.05.
