Title: Physico-Chemical Characteristics Of Some Sudanese Date Cultivars As Affected By Traditional Storage Methods
Author: Eltom, Rawah Babiker
Abstract: Three common Sudanese cultivars of dates (phoenix dactyliferal) for the seasons (2005 and 2006) were used in this study. The cultivars used were namely Barkawi (hard type), Gundila (semi soft) and Mishrigi Wad-lagai (soft). The samples were collected for the season 2005, were traditionally stored in the market for 12 months, while those of 2006 season were fresh. They were studied for their physical and chemical characteristics as well as minerals content. All measurements were made at the “Tamar” stage of development. The physical measurements include fruit weight, pulp and seed weight, pulp and seed percentage and pulp/seed ratio. Samples were proximately analyzed for moisture, crude protein, fat, total carbohydrate, crude fiber and ash content. Minerals assessed were Ca, Mg, Na and K as macro-elements Fe, Zn, Ni, Pb, Co and Cu as micro-elements. Fluctuation was observed in all physical characteristics between fresh and stored date, the cultivar Barakawi had the highest fruit weight and pulp seed ratio. Significant differences were observed in moisture, crude protein content and ash content, while non-significant difference was observed in fat, total carbohydrate and fiber %. All the tested macro and micro-elements were detected.
