Physicochemical characteristics of oil from Piritu (Bactris piritu (H. Karst) H. Wendl) seed
Keywords:Bactris piritu, Physicochemical characteristics, Oleaginous, Piritu
In this research several physicochemical properties of Píritu (Bactris piritu (H. Karst) H. Wendl) seed and its crude oil were evaluated. Seeds were transformed into flour by crushing and drying ( 60 ºC for 12 h) and its approximate composition was: moisture content 5.20 %; fat 39.40 %; protein 9.60 %; crude fiber 44.35 %; ash 1.45 %. The flour lipidic fraction was extracted with n-hexane. The following physicochemical characteristics of crude oil were determined: free acidity (0.13 % as oleic acid), iodine index (11.09 cg of I/g), peroxide value (0.30 meq O 2 /kg), refraction index (1.4445 at 60 ºC ), Wiley melting point ( 33.5 ºC ), saponification value (227.47 mg KOH/g), insaponifiable matter (1.00 %), AOM stability (37.88 h), solid fat content (81 % at 10 ºC or 68 % at 20 ºC ). Lauric acid is the main the fatty acid (56.84 %). Píritu seed is an alternative raw material to obtain oil with characteristics similar to coconut oil.
