The peroxide value, acid value and rancidity were determined based on national standard procedure number 4179, on thirty samples. results: The average of peroxide and acid value was 5.2 and 0.5, respectively. Around 7.4 percent of tested oil has a non permissible rancidity value. Also, 87 percent of samples were healthy.
