Phoenix canariensis Hort. Ex Chabaud, also known as the Canary Island palm or ornamental palm, is an endemic species of the Canary Islands and has been widely propagated globally. It has become one of the most important and appreciated ornamental plants, especially in the Mediterranean climate. The fruits are edible but used only for feed as they are bitter. Despite its diffusion, not much data on the composition of these fruits and their application as food are available. The aim of this study was to define the chemical characteristics, especially those of the polyphenolic constituents, of red and yellow varieties of Canary palm dates, and to evaluate their use alone or in different mixes in biscuit production. The yellow variety had higher quantities of fiber (36.88% DW (Dry Weight)) and polyphenolic compounds, while the red variety had a high content of sugars, mainly glucose (22.8% DW). Epicatechin is the most important polyphenol of dates (562 mg/g DW). The use of date palm powder on biscuit production resulted in an increase in hardness, polyphenol and fiber content, and antioxidant activity. Sensory analysis showed that the biscuits obtained with a 25/75 mix of red/yellow date powder had the most overall liking.

突尼斯金丝雀（Phoenix canariensis Hort。Ex Chabaud）枣的理化特性及其在饼干中添加的评估。

加拿大凤凰霍特 Ex Chabaud，也称为加那利岛棕榈或观赏棕榈，是加那利群岛的特有物种，已在全球广泛传播。它已成为最重要和最受赞赏的观赏植物之一，尤其是在地中海气候中。水果是可食用的，但由于苦所以只能用作饲料。尽管其传播广泛，但关于这些水果的成分及其在食品中的应用的数据却很少。这项研究的目的是确定金丝雀枣的红色和黄色变种的化学特性，尤其是多酚成分的化学特性，并评估它们在饼干生产中的单独使用或不同混合物使用。黄色品种的纤维含量较高（干重为36.88％DW），而多酚类化合物含量较高，红色品种的糖含量较高，主要是葡萄糖（22.8％DW）。表儿茶素是迄今为止最重要的多酚（562 mg / g DW）。在饼干生产中使用枣椰子粉可提高硬度，多酚和纤维含量以及抗氧化活性。感官分析表明，使用25/75的红色/黄色枣粉末混合物获得的饼干总体上最喜欢。
