ABSTRACT This study was carried out to evaluate fruit quality of five sweet cherry cultivars grown in Morocco, namely, Burlat, Van, Cerisette, Napoleon and Coeur de pigeon. Significant differences (p˂0.05) were observed across the five cultivars in fruit weight (5.24–8.72 g), geometric mean diameter (14.22–16.36 mm), pH (3.48–4.12), soluble solid content (17.70–24.50 °Brix), total phenolics (426.44–485.69 mg GAE/100 g fresh weight (fw)), total proanthocyanidins (51.17–131.20 mg CE/100 g fw) and total anthocyanins (194.53–267.67 mg cya-3-glu/100 g fw). The antioxidant activity was evaluated by three assays. The values were 11.96–21.04, 16.48–63.96 and 9.62–15.65 mmol TE/g for DPPH scavenging test, FRAP and ABTS, respectively. Volatile compounds were identified and semi-quantified in sweet cherry fruit using solid-phase microextraction in combination with gas chromatography/mass spectrometry (SPME-GC/MS). Nine volatile compounds (benzaldehyde, nonanal, ethyl hexanoate, ethyl octanoate, γ-terpinene, β-pinene, limonene, linalool and 2-ethyl-1-hexanol) were detected in all sweet cherry cultivars. Aldehydes compounds were the most abundant in sweet cherry aroma, followed by terpenes and esters. Correlation between all parameters showed varying trends.

使用形态、生化和挥发性化合物特征的多变量樱桃质量评估

摘要 本研究旨在评估摩洛哥种植的五种甜樱桃品种的果实品质，即 Burlat、Van、Cerisette、Napoleon 和 Coeur de Pig。在果实重量（5.24–8.72 g）、几何平均直径（14.22–16.36 mm）、pH（3.48–4.12）、可溶性固形物含量（17.70–24.50 °Brix）方面观察到五个栽培品种的显着差异（p˂0.05） , 总酚类物质 (426.44–485.69 mg GAE/100 g 鲜重 (fw))、总原花青素 (51.17–131.20 mg CE/100 g fw) 和总花青素 (194.53–267.67 mg cya-3-gfw) . 抗氧化活性通过三种测定进行评估。DPPH 清除试验、FRAP 和 ABTS 的值分别为 11.96-21.04、16.48-63.96 和 9.62-15.65 mmol TE/g。使用固相微萃取结合气相色谱/质谱 (SPME-GC/MS) 对甜樱桃果实中的挥发性化合物进行鉴定和半定量。在所有甜樱桃品种中均检测到 9 种挥发性化合物（苯甲醛、壬醛、己酸乙酯、辛酸乙酯、γ-萜品烯、β-蒎烯、柠檬烯、芳樟醇和 2-乙基-1-己醇）。醛类化合物在甜樱桃香气中含量最高，其次是萜烯和酯类。所有参数之间的相关性显示出不同的趋势。其次是萜烯和酯。所有参数之间的相关性显示出不同的趋势。其次是萜烯和酯。所有参数之间的相关性显示出不同的趋势。
