Table 1. Physical properties of different citrus cultivars.

Table 2. Chemical properties of pulp of different citrus cultivars.

Table 3. Effect of ultrasound on the total phenolic contents (gallic acid equivalent µg/mL) and total flavonoid contents (µg/mL catechin equivalent) of citrus pulp.

Figure 1. Effect of ultrasound on DPPH values in primary x-axis (blue bars showing ultrasonic-treated juice and red bars showing untreated juice) and radical scavenging activity (RSA %) in secondary x-axis (green lines showing untreated juice and purple lines showing ultrasonic-treated juice) of citrus fruits.

Effect of ultrasound on DPPH values in primary x-axis (blue bars showing ultrasonic-treated juice and red bars showing untreated juice) and radical scavenging activity (RSA %) in secondary x-axis (green lines showing untreated juice and purple lines showing ultrasonic-treated juice) of citrus fruits.

Figure 2. Effect of ultrasound on the antioxidant activity (red bars showing untreated juice and blue bars showing ultrasonic-treated juice) and reducing power (green lines showing untreated juice and purple lines showing ultrasonic-treated juice) of citrus fruit. Values are mean ± SD (n = 6); statistical difference is noted as p ≤ .05.
