Thiobarbituric Acid Value

The effects of gamma irradiation and ozone treatment on microbiological and physicochemical properties of bee pollen were investigated. Gamma irradiation at 7.5 kGy reduced the total microbial loads below detection levels (>102 CFU g−1) but after ozone treatment of up to 18 ppm for 8 h the total aerobic bacteria were found in concentrations of more than 103 CFU g−1. Physicochemical properties such as amino acid and fatty acid composition, thiobarbituric acid value, mineral content, and pigment were not significantly changed by gamma irradiation, whereas ozone treatment caused significant changes in fatty acid composition, thiobarbituric acid value, and pigment by lipid oxidation and decoloration (P < 0.05).

Cold Pressed

Cold-pressed seed oil from twelve commercially produced cactus pear cultivars was assessed for oil yield, fatty acid composition, physicochemical properties, quality and stability. Large differences in oil content, fatty acid composition and physicochemical properties (IV, PV, RI, tocopherols, ORAC, % FFA, OSI and induction time) were observed. Oil content ranged between 2.51% and 5.96% (Meyers and American Giant). The important fatty acids detected were C16:0, C18:0, C18:1c9 and C18:2c9,12, with C18:2c9,12, the dominating fatty acid, ranging from 58.56-65.73%, followed by C18:1c9, ranging between 13.18-16.07%, C16:0, which ranged between 10.97 - 15.07% and C18:0, which ranged between 2.62-3.18%. Other fatty acids such as C14:0, C16:1c9, C17:0, C17:1c10, C20:0, C18:3c9,12,15 and C20:3c8,11,14 were detected in small amounts. The quality parameters of the oils were strongly influenced by oil content, fatty acid composition and physicochemical properties. Oil content, PV, % FFA, RI, IV, tocopherols, ORAC and ρ-anisidine value were negatively correlated with OSI. C18:0; C18:1c9; C18:2c9,12; MUFA; PUFA; n-6 and PUFA/SFA were also negatively correlated with OSI. Among all the cultivars, American Giant was identified as the paramount cultivar with good quality traits (oil content and oxidative stability).
