Abstract:Avocados (Persea americana) are a source of monounsaturated fatty acids, dietary fiber, and beneficial phytochemicals. Despite the health benefits of avocados, there is limited nutritional research on Hawaii and Cameroon-grown avocados. The health benefits of the fruit are primarily based on research involving the Hass cultivar. In Hawaii and Cameroon, many other avocado cultivars besides Hass are consumed. The objective of this research is to illustrate the nutrient content variability among the common varieties of Hawaii and Cameroon avocados. In doing so, the data will help consumers make informative decisions when purchasing the fruit. The data will also help decrease the deficiency of nutritional information which may restrict the growth of the local avocado industry in Hawaii and Cameroon. If consumers know the nutrient profile of avocados, they might be more apt to buy locally grown fruits rather than imported fruits.
The nutritional quantities of six Hawaii-grown cultivars and four Cameroon-grown cultivars were analyzed. The Hawaii cultivars were Linda, Beshore, Serpa, Nishikawa, Ohata and Murashige. The Cameroon cultivars were Peteson, Pollock, Fuer Florida and Booth VIII. Fatty acids (FA) were extracted via Soxhlet, then hydrolyzed and quantified via LCMS. Total protein content was determined via Kjeldahl digestion, mineral profile via ICP, and carotenoid content via HPLC. Nutritional profiles varied among the cultivars. The genetic background appeared to have a stronger influence than the environmental and growing factors as cultivars form the same farms differed from each other.
This data will provide information on the most suitable cultivars in a nutritive and commercial perspective. Furthermore, the public in Hawaii and Cameroon will benefit from the nutritional information on avocados grown in their local region. This will also help improve understanding the health benefits of the fruit which are related to their chemical composition.
