Title: Antioxidants in Date Fruits and the Extent of the Variability of the Total Phenolic Content: Review and Analysis
The date fruit is economically important agricultural commodity and a staple food in many countries in the Arab world, North Africa, and the Middle East. Recent interest in its nutritional, health, and therapeutic attributes is manifested by the rise in scientific publications. Dates of various cultivars are widely publicized and highly ranked as rich sources of natural antioxidant constituents and antioxidant activity. Such publicity, whether justified or not, is sometimes accompanied by misconceptions and claims of cultivar- and/or country-wise superiority. This work examines these claims using a dataset generated from scientific studies published over the last three decades focusing on the total phenolic (TP) content of three stages of date maturity, with emphasis on the last stage, the Tamer. The dataset contains TP values (mg GAE/100 g dry matter) from 18 countries and 243 cultivars and included 583 entries with emphasis on the variability of TP values. Statistical analysis indicates a great variability of TP content, both within a particular cultivar and among different cultivars. Claims of cultivar- and country-wise superiority and very high ranking of date antioxidant activity are not substantiated. This work also discusses the probable causes of high variability and calls for a collaboration work to address the issue.
