Changes in Quality Traits and Phytochemical Components of Blueberry (Vaccinium Corymbosum Cv. Bluecrop) Fruit in Response to Postharvest Aloe Vera Treatment

Figures & data

Figure 1. Effect of Aloe vera treatments on weight loss of blueberry fruit (Vaccinium corymbosum cv. Bluecrop) during storage at 0°C and 90% RH.

A.vera: Aloe vera.n = 9 for the weight loss (three replications x three different measurements for each replication).Means in columns with the same letter do not differ according to Tukey’s test at P < .05.Vertical bars indicate the standart errors.

Figure 2. Effect of Aloe vera treatments on respiration rate and firmness of blueberry fruit (Vaccinium corymbosum cv. Bluecrop) during storage at 0°C and 90% RH.

nd: not determined.* The scale ranges from 0 to 100 for very soft to very firm surfaces.n = 9 for the respiration rate (three replications x three different measurements for each replication).n = 120 for the firmness (three replications x twenty fruit x two different measurements for each fruit).Means in columns with the same letter do not differ according to Tukey’s test at P < .05.Vertical bars indicate the standart errors.

Figure 3. Effect of Aloe vera treatments on L*, chroma and hue angle of blueberry fruit (Vaccinium corymbosum cv. Bluecrop) during storage at 0°C and 90% RH.

L*: lightness. n = 120 for the L*, chroma and hue angle (three replications x twenty fruit x two different measurements for each fruit).Means in columns with the same letter do not differ according to Tukey’s test at P < .05.Vertical bars indicate the standart errors.

Figure 4. Effect of Aloe vera treatments on soluble solids content (SSC), titratable acidity and vitamin C of blueberry fruit (Vaccinium corymbosum cv. Bluecrop) during storage at 0°C and 90% RH.

n = 9 for the SSC, acidity and vitamin C (three replications x three different measurements for each replication). Means in columns with the same letter do not differ according to Tukey’s test at P < .05.Vertical bars indicate the standart errors

Figure 5. Effect of Aloe vera treatments on total phenolics, total flavonoids and antioxidant activities (DPPH and FRAP assay) of blueberry fruit (Vaccinium corymbosum cv. Bluecrop) during storage at 0°C and 90% RH.

FRAP: Ferric Reducing Antioxidant PowerDPPH: 2,2’-Diphenyl-1-picrylhydrazyln = 9 for the total phenolics, total flavonoids and antioxidant activity (three replications x three different measurements for each replication).Means in columns with the same letter do not differ according to Tukey’s test at P < .05.Vertical bars indicate the standart errors.
