Effect of gamma irradiation at dose 1 to 6 kGy on quality improvement of sweet tamarind were studied. It was found that the dosage of 1 kGy was sufficient for eliminating all insects which infested in sweet tamarind. Market trials of irradiated sweet tamarind were carried out in 1995-1996. Irradiated sweet tamarind with labelling were sold together with a questionnaire in Bangkok and some provinces in the northeastern. About 1,400 kg of irradiated sweet tamarind were sold out. A total of 47 completed questionnaires were evaluated. The results showed that 97.9 percent of the surveyed consumers satified the quality of irradiated sweet tamarind in terms of insect free and 74.5 percent indicated that they will buy irradiated sweet tamarind again.
