The project was scaled back from the original proposed objectives due to a reduction in funding from the requested amount. In light of this the research emphasis for this year was made following consultation with G. Witney. The aim of this the project for the current funding year is to study the influence of fruit maturity and handling following fruit harvest on the concentration of various phytonutrients of ‘Hass’ avocado. We are analyzing the edible portion of the fruit for water-soluble components (the carbohydrates mannoheptulose and perseitol, water-soluble vitamins), non-soluble components and fatty acids. See Table 1 for the list of vitamins to be assayed.
