Date Palm Byproducts: History of Utilization

 5 he becomes an adult, the date palm will has grown into many palms that will be the basis of his new life after marriage. As a result, date palm has played a major role in the formation of the culture and heritage in Egypt until the present day (Bekheet 2013). Economically, date palms are a major part of the life-supporting plantations in every village in Upper Egypt (El-Mously 2001; Bekheet and Elsharabasy 2015). Moreover, the annual products of date palm are being utilized in many traditional crafts by the cultivators and craftsmen in Egypt (Darwish et al novelty body puff. 2019b); thus playing a huge role in sustaining the rural societies against the immigration to urban cities, as date palm related crafts and cultivations support over one million families in Egypt (Bekheet and Elsharabasy 2015). Thus, the significance of date palm does not only depend on the multiple uses of the fruit in food baby shower net dress, spirits, pharmaceutical, cosmetic and medicinal products, but also on the large number of the secondary products that have been widely used in construction and handicrafts(Bekheet and Elsharabasy 2015). Palm midribs and trunks have been used for roofing in a fashion that still survives in the western oases and the poor rural areas in Egypt (Ahmed 2014; Darwish et al. 2019b).

 Hence, the technical heritage associated with the products of date palm pruning is still thriving as their cheapness and abundance qualified them to be the favorable raw materials for several traditional industries with a know-how that goes back to ancient Egypt (Darwish et al. 2019b). This technical heritage thrives only because of the high adaptability of date palm in the Arab region environment. The date palm can survive in a wide range of temper- ature from −15 to 60 C (Barreveld 1993). Direct sunlight helps palm leaves become stronger, taller, and thicker and helps them grow faster (Zaid and de Wet 2002; El-Mously 2018). Moreover, a date palm provides shade and protection for crops and tolerates high levels of heat and salinity as date palm cultivation is found along the seashore in Egypt (El-Mously 2001). In addition, date palms need less water and maintenance and are less prone to diseases than other trees (El-Mously 2001). Thus, the date palm has represented an eloquent example of the sustainable use of renewable material resources as illustrated in Fig. 1. 3 Distribution of Date Palms in the World The historical roots of date palms cultivation still have a huge impact on the present situation of date palm distribution in the world. Historically, date palm cultivation originated in Iraq (Munier 1973). Now, the Sahara, North Africa, the Arab Peninsula and Iran acquire the most dense date palm plantations in the world as shown in FAO world map of the annual date production (Barreveld 1993). Latest FAO statistics of the number of date palms showed that Saudi Arabia, Algeria, Iran, Iraq and Egypt.
