The formation of oxytetracycline in a date-coat medium

Production of lactic acid from date juice extract with free cells of single and mixed cultures of Lactobacillus casei and Lactococcus lactis

“…To meet this problem, utilizations of poor-quality dates and date by-products have been previously investigated in food product manufacture for example for bakery products, ice-cream, caramel products, ethanol, vinegar (Mehaia 1991), oxytetracycline (Abou-Zeid et al 1993), single-cell protein (Jalaluddin et al 1995;Nancib et al 1997) and lactic acid (Nancib et al 2001). In fact dates contain large amounts of reducing sugars, especially glucose, and fructose at levels of 73-83% (dry basis), and they also contain protein, lipid, fibre, mineral elements and some vitamins (Abou-Zeid et al 1991), thus making date extracts quite suitable as fermentation substrates.…”

Date syrup: Effect of hydrolytic enzymes (pectinase/cellulase) on physico-chemical characteristics, sensory and functional properties

“…This category of dates is generally discarded or partially integrated in animal feed . Some studies have been carried out to use these low quality dates to develop new products such as metabolites or biomass production (Abou Zeid, Abderrahman, & Baghlef, 1991;Besbes et al, 2006) or use a date of good quality to product some products such as bakery, beverage, jam and the confections (Achour, Hamdi, & Benzarti, 1996;Al-Hooti, Sidhu, Al-Otaibi, Al-Ameeri, & Qabazard, 1997;Benamara, Chibane, & Boukhlifa, 2004;Khatchadourian, Sawaya, Khalil, & Mashadi, 1983;Youssif, Abou Ali, & Bou Idreese, 1990). The low quality dates are a rich source of carbohydrates (73.3e89.55 g/100 g dry matter) composed mainly of sugars and dietary fibres and are safe for human consumption (Besbes, Drira, Blecker, Deroanne, & Attia, 2009).…”

Heating effects on some quality characteristics of date seed oil

“…Little research has been undertaken on date palm seeds; this has focused particularly on their chemical composition (Al-Showiman, 1990;Al-Hooti, Sidhu, & Qabazard, 1998;Devshony, Eteshola, & Shani, 1992;El-Shurafa, Ahmed, & Abou-Naji, 1982;Hamada, Ha-shim, & Sharif, 2002). Date palm seeds are a waste product of many industries based on the technological transformation of date fruits (Al-Hooti, Sidhu, Al-Ota-ibi, Al-Ameeri, & Qabazard, 1997;Hobani, 1998;Khat-chadourian, Sawaya, Khalil, & Mashadi, 1983;Youssif, Abou Ali, & Bou Idreese, 1990;Youssif, Alghamdi, Hamad, & Mustafa, 1996;Youssif & Al-Ghamdi, 1999) or on their biological transformation (Abou Zied & Baghlef, 1983;Abou Zied, Abderrahman, & Baghlef, 1991;Abou Zied & Khoja, 1993;Al-Obaidi & Berry, 1976;Nacib, Nacib, & Bourdant, 1997;Nacib et al, 1999). Then, a large quantity of date seeds could be easily collected from the date processing industries or from the waste products (represent nearly 30% of the production in Tunisia) coming either directly from the palm grove or from the gap-conditioning stations.…”
