摘要：15 tehina halvah samples which is made from sugar, flour, sesame oil and other ingredients were examined in this research. Water and oil content along with some chemical and physical properties of the oils were investigated. The mean value of the investigate parameters were follows; water 3.33%, oil 32.55%, peroxide number 3.43 meq g O2/kg oil, free fatty acids (as oleic acid) 0.42%, iodine number 105 g iodine/100 g oil, saponification number 191 mg KOH/g oil and refractive index 1.468 (at 20 oC). Some of the oils extracted from some samples was hardened immediately after extraction process. For this reason, melting points of these samples were measured, and it was concluded that these samples may have been adulterated by using different oils other than sesame oil which is specified in food regulations laws.
