Reviving Traditional Know-How: A Comprehensive Analysis of Date Juice Processing in Moroccan Oases

Abstract

Moroccan oases host a rich array of date palm varieties, renowned for the traditional expertise in crafting local products from dates. Date juice, a quintessential local product with significant heritage value, is facing a decline in appreciation. This study delves into indigenous knowledge surrounding date juice processing. Surveys involving one hundred women from the Alnif and Tata oases in Morocco’s pre-Saharan regions were conducted. Results reveal the use of 56 medicinal and aromatic plants from 33 families and 53 genera in date juice preparation, with Lamiaceae and Asteraceae families most prevalent. Noteworthy species include Corrigiola telephiifolia Pourr. (85 citations), Cynara humilis L. (66), Cyperus longus L. (65), and Alpinia officinarum Hance (64). Date juice holds significance in traditional medicine, prized for its sensory qualities and therapeutic benefits resulting from blending date fruit with aromatic and medicinal plants. The study sheds light on traditional manufacturing processes, including palm variety selection and plant choices. It also offers insights into therapeutic applications aligning with medicinal practices. These findings enrich understanding of cultural traditions and provide essential information for their preservation and propagation.
