Abstract
The present study was designed to evaluate the effect of fortification of halawa spread, jam, coffee and molasses with different levels of date pits powder on sensory and chemical characteristics. Samples in the present study were divided into four groups of fortified halawa spread, jam, coffee and molasses with date pits at different levels described as follows : Date pits halawa spread with levels (10,20, 30%) were replace with Sesame. Date pits jam with levels (10,20, 30%) were replace with date. Date pits coffee with levels (10,20, 30%) were replace with Coffee. Date pits molasses with levels (10,20, 30%) were replace with water. Also investigate the effect of the best chosen fortified halawa spread, jam, coffee and molasses with different levels of date pits powder on hypercholesterolaemic rats. Fifty six male albino rats (weighting 140 ±5g), were divided into eight groups (each group 7 rats). The first group fed on basal diet, served as a normal control group (-ve). Fourty nine fed on 2% cholesterol orally daily and injected with cholic acid (0.05 ml/100 B.W/ rats) intramuscularly once every week for 28 days in an attempt to induce a case of hypercholesterollaemic and classified to seven groups, positive control group (+ve) fed on basal diet, treated group fed on basal diet with (10g/100g/diet) date pits powder, treated group fed on basal diet with (20g/100g /diet) date pits powder, treated group fed on basal diet with (10g/100g /diet) date pits jam, treated group fed on basal diet with (20g/100g /diet) date pits jam, treated group fed on basal diet with (10g/100g /diet) date pits halawa spread and treated group fed on basal diet with (20g/100g /diet) date pits halawa spread. After eight weeks, rats were anaesthetized by diethyl ether and sacrificed; blood samples were collected then separate serum to measure some biochemical parameters. Date pits products of 20% DP halawa spread, 10% DP jam, 20% DP coffee and 20% DP molasses found acceptable by the panelists. Results showed that the addition of date pits powder to the products of halawa spread, jam, coffee and molasses increased total content of fibers, protein, carbohydrates and ash, but decreased total fats. Also, results showed that 20% DP halawa spread, and 10%DP jam are chosen to be the best. The biological results showed significant decrease in body weight gain, food intake and feed efficiency ratio in treated groups comparing with positive control (+ve) group, as well as significant reduction in BMI, TC, TG, NEFA, LDL-c, VLDL-c, AI , Leptein hormone and Malondialdehyde (MDA). Also, there were an increase in HDL-c, FT4, FT3, adiponectin, total antioxidant capacity (TAC) and superoxide dismutase (SOD) levels in treated groups comparing with positive control group (+ve). According to the results of this study, It is concluded that the examined fortified halawa spread, jam, coffee and molasses with different levels of date pits powder had a therapeutic protective effect which may be attributed to some potent bioactive constituents of date pits.
