*1a and 1b show the effects of different maltodextrin concentration and drying temperaratures on the colour characteristics of spray-dried poeders.In general,the colour characteristics of spray-dried poeders were significantly impacted by maltodextrin concentration and drying temperature.For the lightness,the colour of products was significantly affected by maltodextrin concentration(p<0.01).An increase in the lightness of porducts was significantly obtained by increasing maltodextrin concentration form 10%to20%.However,there was no significant difference in lightness of samples when the concentration increased from 20% to 30%.A consistent result was also observed in terms of the colour characteristics of the a*/b* value and the hue angle were obtained in the sample with an added 10% concentration of maltodextrin,both indicating more redness.Moreover,the maltodextrin concentration also impacted on the chroma value of samples(p<0.001)Decreasing
