The strawberry tree ( L.), grown throughout the Mediterranean, produces edible fruit; as it is easily bruised, the sweet, reddish fruit is used mostly to prepare jams, marmalades and alcoholic beverages. As the genus is paraphyletic, phytochemical analysis can assist in defining the fruit composition with the species L. (). Here we report on the carbohydrate, total sugar, protein, fat, fiber, ash, and mineral content of wild fruit, harvested from 45 specimens from five locations. The dominant nutrients were carbohydrates (78.2-84.8 g/100 g), total sugars (52.1-67.2 g/100 g) and dietary fiber (11.0-20.1 g/100 g). Other important nutrients supplied by fruit include P, K, and Fe. The fruit was observed to contain health-promoting components providing 42 and 36%, of recommended daily allowance (RDA) for fiber and zinc, respectively, as well as iron and manganese, at levels exceeding minimum RDA. The free-sugar profile revealed high glucose followed by fructose content with minor amounts of sucrose (14, 11, and 6 g/100 g, respectively). Significant differences both between regions and within individuals were observed for several traits. The richness of fruit nutrients in confers nutritional value and as such, a promising alternative fruit source.
草莓树(Arbutus unedo L.)生长于地中海地区,其果实可食用;由于果实易碰伤,这种香甜的红色果实主要用于制作果酱、橘子酱和酒精饮料。由于该属植物是并系群,植物化学分析有助于确定草莓树(Arbutus unedo L.)果实的成分。在此,我们报告了从五个地点的45个样本中采集的野生果实的碳水化合物、总糖、蛋白质、脂肪、纤维、灰分和矿物质含量。主要营养成分是碳水化合物(78.2 - 84.8克/100克)、总糖(52.1 - 67.2克/100克)和膳食纤维(11.0 - 20.1克/100克)。草莓树果实提供的其他重要营养成分包括磷、钾和铁。观察发现,该果实含有促进健康的成分,分别提供了膳食纤维和锌推荐每日摄入量(RDA)的42%和36%,以及铁和锰,其含量超过了RDA的最低水平。游离糖谱显示葡萄糖含量高,其次是果糖,蔗糖含量较少(分别为14、11和6克/100克)。在几个性状上,观察到地区之间和个体内部都存在显著差异。草莓树果实营养丰富,具有营养价值,因此是一种很有前景的替代水果来源。
