There are several works related to the good potential of soy protein
isolate to be applied as the encapsulating wall material. Microencapsulation
of oil or water soluble substances with SPI was particularly
investigated using spray-drying [14–16]. So far there has been no
work published on the spray drying of tamarind pulp using soya protein
isolate as a carrier agent. Therefore it is worthwhile to study the potential
of soya protein isolate in the production of tamarind pulp powder
and to optimize the process conditions to obtain the quality powder of
desirable characteristics.
