Lipid and Fatty Acid Composition of Mesocarp and Seed of Avocado Fruits Harvested at Northern Range in Japan

Abstract

The lipid and fatty acid composition of the mesocarp and seed of avocado fruit grown and harvested in Japan, which is located at the northern range of the avacado, was investigated and compared to an imported avocado purchased commercially. The potential of the avocado mesocarp as an agricultural product in Japan was also explored. Total lipids (TL) accounted for approximately 20% of the mesocarp. Further analysis showed that the neutral lipid (NL) fraction accounted for at least 95% of the TL, and almost 90% of NL was triacylglycerol. Monoenoic acids accounted for at least 65% of the total fatty acids, and oleic acid, which is regarded as an especially important functional component of avacado accounted for approximately 50% of the monounsaturated fatty acids. A comparison of the Japanese avocado cultivars and an imported avocado cultivar in the present study revealed no significant differences in the lipid and fatty acid compositions. Therefore, production of avocado fruit, which is rich in various nutritional components, is expected to be increased on a larger number of farms in Japan in the future. It is believed to be necessary to carry out further verification, such as the establishment of a cultivation technique adoptable to Japan, examination of optimal soil and land features, and cultivar selection.

Protective Effect of Pulp Oil Extracted fromCanarium odontophyllumMiq. Fruit on Blood Lipids, Lipid Peroxidation, and Antioxidant Status in Healthy Rabbits

“…Sample of this study also had lower palmitic acid compared to C. schweinfurthii pulp oil (40.31% versus 60.88%) [13]. Total MUFAs of the CO pulp oil reported in this study also were much lower compared to high-fat fruits such as olive (56–86%) and avocado (65–68%) [14, 15]. Meanwhile, PUFA of the CO pulp oil (14%) was comparable to avocado oil (12–14%) but lower than olive oil (3.5–21.5%) [14, 15].…”

Associations of whole-blood fatty acids and dietary intakes with prostate cancer in Jamaica

“…Oleic acid accounts for approximately 50% of the monounsaturated fatty acid content of avocado [24]. However, avocado also contains phytochemicals that act as antioxidants exhibiting chemopreventive properties [25].…”

Avocado consumption is associated with better diet quality and nutrient intake, and lower metabolic syndrome risk in US adults: results from the National Health and Nutrition Examination Survey (NHANES) 2001–2008

“…Epidemiological evidence and intervention studies generally support the association between the consumption of energy-dense/high-fat diets with being overweight [36,37]. Insulin resistance, a key pathogenic link underlying the cluster of metabolic abnormalities seen in metabolic syndrome, is adversely effected by saturated fat and improved with MUFA [39-41]. Tree nuts, which are similar to avocado in dry weight composition including dietary fiber and MUFA content, have not been shown to increase body weight or metabolic syndrome risk in numerous clinical and epidemiological studies [42-46].…”
