| مستخلص: | Red pitaya is a rich source of dietary fibers, vitamins, minerals and antioxidants. Consumption of fruit products have shown to induce beneficial changes in pathways related to cardiovascular health. Therefore, the present study was designed to determine the nutritional composition and antioxidant properties of spray pitaya powder (SPP) and its supplementation effects on biochemical parameters among normocholesterolemic subjects in Mempaga, Pahang. This study comprises of three phases. In phase one of the study, nutritional composition analysis revealed that SPP contains 10.9% moisture, 1.22 g ash, 1.59 g protein, 80.33 g carbohydrate, 0.007 g fat and 17.70 g total dietary fiber per 100 g SPP. SPP also contained potassium, sodium, magnesium, zinc and calcium. In SPP, the vitamin C content was 17 mg/100 g SPP. Meanwhile, other trace elements are very minute. The data demonstrated that antioxidant properties in SPP using FRAP assay, DPPH and total phenolic exhibited 0.396 mMFeSo4/g (FRAP value), 51.1% (radical scavenging effect) and 156.40 mgGAE/100g (total phenolic content) respectively. This finding showed that SPP contained beneficial nutrients such as dietary fibers, vitamin C, minerals and antioxidants. Phase two of the study (Chapter 4) involved in-vivo experiment to determine the effect of SPP on the liver and kidney function of normal Sprague Dawley rats. A total of 32 Sprague Dawley rats were divided into a control group and three treatment groups, which were given 0.83 g/kg Body weight (BW)/day, 1.67 g/kg BW/day and 2.5 g/kg BW/day of SPP respectively for 4 weeks. During the experiment, body weight and enzyme markers (liver and kidney enzymes level) were measured. Results showed that the body weight of rats significantly increased throughout the study period. There was no significant difference (p > 0.05) in changes of liver enzymes (AST, ALT and ALP) and kidney (BUN and Creatinine) products from both male and female rats in all treatment groups as compared |
