3.1. Fat content and fatty acids
The fat content for each sample and the percentages of total SFA, MUFA, PUFA and individual TFA are presented in Table 1; all data are expressed as % of total FA. Data are only shown, if the FA was present at >0.5% of total FA in at least one product; if the FA are present in one product >0.5%, lower values may be present for this FA in other products. For TFA, all values are included. The mean TFA level in bakery products analysed in 2001 was 5.9% of total fatty acids, compared with 0.7% in products analysed in 2007. Values for individual products ranged from non-detectable to about 14% in both periods. In 2001, 27 of 34 products (79%) had TFA levels higher than 2% while, in 2007, only 3 of 41 products (7%) exceeded this level. The three gluten-free biscuits analysed in 2006 had TFA levels above 2%, but after reformulation TFA levels were 0.5–0.7% (Table 1).
