Antibacterial property of commonly used spices in Abuja, Nigeria Paper ID: AJFSN-08-08-2021-190
Abstract : Spices are additives to improve the flavor, taste, and colour of food. Spices are also known to extend shelf life by inhibiting growth or decreasing food borne pathogens. The study is aimed to evaluate seven spices for antibacterial properties on some bacteria. The local and botanic names of the seven spices are Ehuru (Monodora myristica), Uziza (Piper guineese), Turmeric (Curcuma longa), Garlic (Allium sativum), Ginger (Zingiber officinale), Cayenne pepper (Capsicum annum), cinnamon (Cinnamonum cassie) were purchased in the market in Abuja, Nigeria and identified in Herbarium Unit of National Institute for Pharmaceutical Research and Development, these spices were dried and pulverized into powder. These powders were extracted with 70% methanol into crude extracts. The crude extracts were screened for antibacterial property against Salmonella typhi, Escherichia coli, Staph. aureus and Bacillus subtilis at varied concentration of 80,40, 20 and 10 mg/mL using the agar. Curcuma longa and Piper guineese inhibited the growth of test bacteria at the concentration of 10 mg/mL while Cinnamonum cassie and Capsicum annuum inhibited the growth of three of the test bacteria. Zingiber officnale crude extract was found to be resistance against to E. coli and Salmonella typhi, while Allium sativum extract was also exhibit resistance to Sal. typhiand E. coli growth. Monodora myristica crude extract was found to have not inhibitory potential on the test bacteria. The concentration of 10 mg/mL

Effect of substitution of glucose syrup with date syrup on the nutritional quality of Granola bar Paper ID: AJFSN-08-08-2021-189
Abstract : Granola bar is a ready- to- eat snack food that is highly nutritious due to the presence of different ingredients such as oat, cashew nut and puffed rice. They are rich in protein, dietary fiber, vitamins and minerals. They consumed in place of breakfast or in between meal to temper hunger for people on the go. In order to make granola bar even more nutritious and healthy, the sugar content can be substituted with natural sweeteners. Therefore, the overall objective of this study was to produce 5 high energy nutritious granola bars by combining oat, puffed rice, corn flakes, cashew nut, chickpea, raisins and substituting the glucose with date syrups namely: (GBA 100% glucose syrup:0 % date syrup (Control); (GBB 75% glucose syrup: 25% date syrup); (GBC 50% glucose syrup: 50% date syrup); (GBD 25% glucose syrup: 75% date syrup); and (GBE 100% date syrup: 0 % glucose syrup). Microbial load, nutrient composition, sensory evaluations were performed. Flaxseed had the highest total viable count, fungal count and chickpea has the highest Salmonella Shigella count. On dry weight basis, moisture content ranged from (1.05±0.0 to 1.07±0.0); protein (8.5±0.02 to 12.6±0.05); fiber (0.53±0.04 to 1.1±0.02). GBC has the highest moisture content (1.07±0.0). GBE was scored higher in taste (4.05), chewiness (3.65), aftertaste (3.75) and overall acceptability (4.05). GBC scored (4.05) in color and crunchiness (4.25). In conclusion, date syrup can be substituted for glucose syrup in the production
