Abstract: (4752 Views)
Some physico-chemical characteristics of Iranian linseed oil (Linum usitatissimum) such as oil content (44.25%), refractive index (1.47), peroxide (7.21meqO2/Kg Oil), iodine (170.67gI2/100g Oil), acid (3.10mgNaOH/g Oil) and saponification (191.73mgKOH/g Oil) values and fatty acid profile (C16:0, C18:0, C18:1, C18:2, C18:3) were studied. For preservation of ω-3 ingredients, the linseed oil that containing 43.18% of ω-3 fatty acid, were kept in frozen condition (nitrogen atmosphere and -30 º C temperatures) and its peroxide value was determined after 0, 7, 30, 60 and 90 days. Statistical analysis showed significant difference (p<5%) average amount of peroxide value only in first 7 days of storage time and its increase (8.30%) conformed to international standard.
