Developing tree fruit quality indexes based on consumer acceptance and market life.
In recent years, we have been developing stone fruit quality indexes based on consumer acceptance and fruit market life with the main goal of increasing fruit consumption.To reach this goal we have taken the following steps: first, we evaluated market life potential based on internal breakdown susceptibility for the most important peach, nectarine and plum cultivars in the California industry.Second, we conducted soluble solids concentration (SSC) and titratable acidity (TA) surveys, which indicated the potential fruit quality range for these cultivars within the industry.Third, we investigated the potential role of pre-harvest factors on these quality attributes.Fourth, we studied the relationship between sensory attributes such as sweetness, sourness, aroma, texture, and overall fruit flavor intensity and the measurement of firmness, SSC, TA and sugar-to-acid ratio (SSC:TA) using a trained taste panel.And finally, we used the above data to design large “in store” consumer tests for the different stone fruit cultivars.After completion of these steps, our industry will have enough solid information to propose a high quality fruit standard if necessary.
