However, tamarind pulp like other fruit juices contains a high proportion of low molecular weight components such as fructose,glucose, and tartaric acid which can cause a stickiness problem during spray drying. The stickiness problem is mainly due the low glass transition temperature of these components which is about 5, 31 and 18 °C for fructose, glucose, and tartaric acid, respectively. Due to this,the spray drying of tamarind pulp is complex. During drying at temperatures normally prevailing in spray dryers, they tend to stick to the walls of the dryer and finally give a paste like structure instead of powder.
