The numbers with the superscripts of the same letter in the same row of each property represent similar values at confidence level. The numbers of each column are similar at the 0.05 confidence level. B1: RTS beverage with encapsulated folic acid; B2: RTS beverage with free folic acid; B3: RTS beverage with empty alginate particles; B4: regular RTS beverage; RTS: ready to serve.
