The results, detailed in Table 1, were statistically compared after
exclusion of sample #19. Total fatwas statistically lower in the plain
and butter cookies in comparisonwith all the groups (p < 0.01). On
a fat basis, statistical differences were observed for all fatty acid
groups. SFA were higher (p < 0.01) in wafers, covered/filled and
butter cookies, while MUFA and PUFA were prevalent in the plain
group (p < 0.01). On a fresh mass basis, the SFA followed a similar
pattern in the samples with higher fat amount, in wafers, filled/
covered cookies and puff-based ones. The butter cookies and bis-
cuits and, particularly, the plain ones had significantly lower
amounts of SFA on a fresh mass basis. The differences among the
MUFA and PUFA observed in the fat were reduced on a mass basis,
particularly in the former, since the sampleswith higher proportion
of these fatty acids in the fat were simultaneously those with the
lower fat amounts, reducing the significance of this direct com-
parison on a fresh mass basis. As to the TFA, and with sample #19
excluded, the amounts were low in all classes except for the wafers
group, particularly when expressed on a freshmass basis, therefore
associated with a higher use of hydrogenated fats
