‘Aliza’ is a new pomelo × mandarin hybrid (Citrus maxima, cv. Red Chandler × Citrus reticulata, cv. Ora) developed by the Israeli citrus breeding program at the Volcani Institute. Here, we aimed to characterize the quality and flavor of ‘Aliza’ fruit as compared to other commercial citrus fruit, specifically pomelo (C. maxima), grapefruit (Citrus paradisi), orange (Citrus sinensis) and mandarin (C. reticulata). ‘Aliza’ fruits have a similar size as grapefruits, but have a thinner peel and a unique yellowish/golden color. ‘Aliza’ fruits are completely seedless and have especially high juice contents. They also have a unique, highly preferred flavor, characterized by high sweetness and moderate bitterness and acidity, with strong citrusy and tropical fruity aromas. Sensory analyses conducted with the aid of a trained panel and an electronic tongue revealed that the flavor of ‘Aliza’ fruits is different from the flavors of other citrus species. Consumer acceptance and preference tests revealed that ‘Aliza’ fruit are highly appreciated and favored. The aroma volatile profile of ‘Aliza’ fruit was somewhat similar to those of pomelo and grapefruit, but very different from those of orange and mandarin. Overall, ‘Aliza’ fruits can be distinguished from other citrus fruits by their unique color, high juice content and exceptional, unique flavor.
