as carrier were further investigated at a fixed addition of MD (20 g/100 g). The results are shown in Fig. 1B. With the addition of b-CD increased from 2.0 g/100 g to 4.0 g/100 g in the feed the flour yield sharply increased by 11.62%e43.55%, compared to the flour yield with 20 g/100 g MD only. When 30 g/100 g MD and 24 g/100 g b-CD/MD (1/5, w/w) were used as carriers comparative flour yields (39.85 and 40.41 g/100 g) were achieved. This implied that the required level of combined carrier of b-CD/MD was lower than that of MD to achieve the same level of flour yield.
