نبذة مختصرة : The objectives of the study were to determine the physical-chemical and organoleptic properties of Palu fried onions at the varying utilization frequency of cooking oil, i.e. F0 : fresh oil , F1 : 1 time of using , F2 : 2 times of using , F3 : 3 times of using , F4 : 4 times of using , F5 : 5 times of using and F6 : 6 times of using , the each level was replicated three times. The frequency of cooking oil utilization was significantly affected to decreasing color, texture, moisture content, oil content and panelist preference level on the crispness of Palu fried onions as well as increasing oxidation rate of unsaturated fatty acids at the cooking oil. Physical - chemical and organoleptic quality of Palu fried onions were obtained of the best fresh frying utilization cooking oil, 1, 2, and 3 times of using cooking oil , respectively. The use of cooking oil more than 3 times oxidized free fatty acids, so it is less feasible to use based on the life time and health aspects of fried onions.ABSTRAKTelah dilakukan penelitian untuk mengetahui sifat fisik-kimia dan organanoleptik bawang goreng Palu yang digoreng pada berbagai taraf frekuensi pemakaian minyak goreng yaitu F0: minyak segar, F1 : 1 kali pemakaian, F : 2 kali pemakaian, F 3 : 3 kali pemakaian, F4 : 4 kali pemakaian, F 5 : 5 kali pemakaian dan F : 6 kali pemakaian, setiap taraf diulang tiga kali. Frekuensi pemakaian minyak goreng pengaruhnya sangat nyata menurunkan warna, tekstur, kadar air, minyak dan tingkat kesukaan panelis terhadap kerenyahan bawang goreng Palu serta meningkatkan laju oksidasi asam lemak tidak jenuh pada minyak goreng. Mutu fisik-kimia dan organoleptik bawang goreng Palu secara berturut-turut terbaik diperoleh dari penggorengan menggunakan minyak goreng segar, 1, 2 dan 3 kali pemakaian. Pemakaian minyak goreng > 3 kali, asam lemak bebas telah teroksidasi sehingga kurang layak untuk digunakan jika ditinjau dari aspek daya tahan simpan bawang goreng dan kesehatan.
