This work explores the preliminary feasibility of employing low-pressure cold plasma technology for the modification of the properties of chia flour. Chia flour was exposed to low-pressure plasma in the air for 5 min, 10 min, and 15 min, at two different power levels (40 W and 60 W). The oils extracted from untreated and treated chia flour were exh...
