A considerable variation was observed among the fatty acid
profiles of organic and conventional farming systems (Table 4). A
total of 13 different fatty acids were identified in the Maltaise
demi-sanguine juice. The fatty acids detected had an even number
of carbon atoms ranging from C14 to C22 in both farming systems
except nonadecanoic acid (C19:0) which contained an odd number
of carbon atoms. The farming system had a significant influence on
the major fatty acids content of the Maltaise demi-sanguine juice.
In this regard, significant differences between the two farming systems
were observed for palmitic (C16:0), palmitoleic (C16:1), stearic
(C18:0), oleic (C18:1), linoleic (C18:2), linolenic (C18:3),
steradonic (C18:4) and behenic (C22:0) acid concentrations.
Moreover, total fatty acid content was higher in the organicallygrown
(136.05 lg/ml) than in the conventionally-grown juice
(58.07 lg/ml). In addition, polyunsaturated fatty acids represented
the highest concentrations in both farming systems compared to
saturated and monounsaturated fatty acids with linoleic acid being
the most dominant compound (15.53 lg/ml in conventional and
49.64 lg/ml in organic juice) followed by oleic and linolenic acids.
This result was in accordance with that of
