20 samples of biscuits of industrial origin were analyzed in order to deter
mine their fat content (5-25.1%). The composition of the fat content was fu
rther analyzed by gaschromatography: the results showed a clear prevalence
of saturated fatty acids (from 45-50% to a maximum of 85%). Only in one pro
duct containing hydrogenated fats, a fairly high percentage of trans oleic
acid was found (6.5%).
