 EFFECT OF SENSORY EVALUATION OF SYRUP PRODUCED FROM DATE FRUIT

 

1.1 Background to the Study

The date palm (Phoenix dactylifera) is one of the major fruit trees in Egypt (El- Assad et al.,2005). Its production and consumption is growing continuously due to its therapeutic properties beside its high nutritive value (Karagul et al.,2004). Date fruit consumption is an important source of supplying mineral and vitamin elements in a balanced nutrition regime (Al-shahib and Marshall,2003). Research proves that when dates are eaten alone or in mixed meals with plain yoghurt have low glycemic indexes (Yousuf et al.,1996; Miller et al.,2003). The good news is that consumption of dates may also benefit in glycemic and lipid control of diabetic patients (Miller et al., 2002,2005). Lately, several therapeutic virtues are assigned to the date palm and its derivatives. Date fruit has anti tumor activity (Ishurd and Kennedy,2005), antioxidant and anti-mutagenic properties (Vayalil,2002; Mansouri et al.,2005). The fruit has been recommended in folk remedies for the treatment of various infectious diseases and cancers (Duke,1992). Dry date fruits are used in Indian traditional medicine after childbirth as immunostimulant (Puri et al., 2000). Extracts of the dates provided to the women after childbirth stimulate their immune system (Puri et al.,2000). Aqueous date extract was also found to inhibit significantly the lipid per oxidation and protein oxidation in a dose-dependent manner (Al-Laith,2007). Further more, Al-Shahib and Marshall (2003) concluded that, in many ways, dates may be considered as an almost ideal food, providing a wide range of essential nutrients and potential health benefits. On the other hand, a polysaccharides isolated from dates presented an antitumor activity (Ishurd and Kennedy,2005). Extracts of the pits date decrease quickly and meaningfully the women wrinkles (Bauza et al., 2002).

1.2 Problem Statement

Increased  intake  of  added  sugar  might  increase the risks for  obesity, cardiovascular  diseases,  dental caries,  glucose  intolerance,  diabetes  mellitus, hypertension  and  behavioral  complications  such  as hyperactivity  in  children  (Anderson, 1997;  Johnson and  Yon,  2010). Date has shown to have low glycemic index (Yousuf et al.,1996) which can help solve this problem.It is hoped that processing of date fruit into syrup will improve its consumption.
