| method_description | Total phenolics was measured on all fruit pulp samples by combining fruit and any juice lost during thawing in a zip top bag. Fruit was homogenized by rolling a weighted glass bottle over the bag, crushing the fruit and achenes. Homogenate was tested for titratable acid and then 1.5 mL was saved in three 2 mL tubes and stored at −80 °C. Thirty minutes prior to testing, one vial of each of the stored samples was thawed, vortexed and centrifuged. The determination of total phenolics was performed using the Folin-Ciocalteu method as described by Waterhouse (2002) modified for use in 90-well, flat-bottomed microplates (Greiner Bio-One, Monroe, NC, USA). |
