| Abstract:
Several commercial characteristics of 5 Spanish olive oil cultivars were studied in the north-eastern Mediterranean area of Spain. The main observations were carried out during a five year period, 1992–1996. All fruit samples were taken with a maturity index ranging from 2.5 to 3.5. The results show that ‘Picual’ trees produced the largest fruits with a high pulp/stone ratio, while ‘Arbequina’ produced the smallest fruits with the lowest pulp/stone ratio. The oil content, was highest in ‘Blanqueta’, followed by ‘Empeltre’, ‘Arbequina’, ‘Morrut’ and ‘Picual’. Regarding oil characteristics, there were significant differences were found in polyphenol contents, bitterness (K225), oxidation resistance and fatty acids composition (mainly in palmitic, oleic and linoleic acid). On the whole, the parameters of fruit, oil content and oil characteristics indicated a wide range of variation between the 5 studied cultivars. | |
