The optimum temperature and sample weight of popping for some Egyptian rice cultivars were determined by using new technique depending on invented electric local equipment. Results of both seasons revealed significant variance among cultivars for most studied characters. The superior values for weight of popped, popping %, expansion ratio, and least values for density were noticed with Giza 178 rice cultivar in 2021 and 2022 seasons. However, the superior values for weight of popped, popping % and expansion ratio. While, the lowest value for density was recognized with 190oC in 2021 and 2022 seasons. Superior values for weight after popping were recognized with 190 and 210 oC in both study seasons respectively. Furthermore, the superior values for popping%, expansion ratio, and lowest values for density were noticed by using 40 g sample weight in both study seasons. Furthermore, the superior values for weight after popping and weight of popped rice were noticed with Giza 178, 190 0C and 45g sample weight in both study seasons. However, superior values for popping % and expansion ratio while lowest values for density were indicated with Giza 178 and using 40 g sample weight at 190 0C in both study seasons. Moreover, data declared that the least values for popping %and expansion ratio. while, the highest values for density were indicated with Sakha 101 rice cultivar and 45 g sample weight at 170 0C in both seasons. Economic value of Giza 178 was enhanced as considerd lower price than other Japonica types in market.
