Effect of Processing Method of Kidney Beans (Phaseolus Vulgaris) on Carcass Quality, Organ Weight and Organoleptic Properties of Broiler

Abstract Effect of processing method of kidney beans (phaseolus vulgaris) on carcass quality, organ weight and organoleptic properties of broiler was studied using one hundred and twenty day-old chicks (Arbo acre strain). Raw, dehulled and boiled KB were used for treatment 2, 3 and 4, respectively. Prior to grinding of KB, 50kg was boiled at 100 0C for 1 hour, 10kg was dehulled by immersing in cool water for 20 hours, and seed coat removed. The work was carried out using completely randomized design, with four treatments and three replicates of 10 birds per replicate. Data collected were analyzed using SPSS version 22. The relative weight of liver, spleen and heart had no significant effect (p>0.05) within the dietary treatment. The weight of the liver was smaller in birds fed raw kidney beans meal and the liver was characterized by marked coagulative necrosis. The weight of the gizzard was significantly (p<0.05) higher in birds fed control diet. Furthermore there were no significant differences (p>0.05) in birds fed boiled, dehulled and control diets on the breast weight but significantly smaller in those fed raw diet meal. There were also no significant differences on the drumstick, thigh, neck and head size. Tenderness was not significantly affected by the dietary treatments. Juiciness, taste, and flavour intensity showed significant differences within the dietary treatment while overall acceptability showed a significant increase with the boiled kidney bean meal. Consequently, birds fed with BKD performed better in the organoleptic properties, while those on dehulled kidney beans meal gave better result for organ weight and carcass yield. In conclusion, sensory characteristics, organ weight, and carcass yield is an indication that kidney beans especially the boiled and dehulled one can serve as a feed ingredient in broiler ration would have no adverse effect.

Keywords— dehulled kidney beans, organoleptic properties, sensory characteristics.

UHPLC-DAD-ESI-MS/MS of Ethanolic Extract of the Flowers from Spathodea Campanulata Beauv. in Cuba

Abstract A sample of ethanolic extract of the flowers from Spathodea campanulata Beauv. was scrutinized using a UHPLC-DAD-MS/MS Thermo scientific Dionex Ultimate 3000 RS coupled to a Thermo scientific LTQ XL mass spectrometer. In addition, about nine different chemical compounds were tentatively identified in this species based on chromatography retention time (Rt), UV and MS/MS spectra and compared with those of isolated authentic compound and literature data in our country for the first time. Information obtained from these studies can be used as biomarkers in the identification and standardization of this flower as an herbal remedy and also towards monograph development on the plant.

Keywords— UHPLC, Flowers, Chemical compounds, Ethanolic extract, Spathodea campanulata.

Comparison of different Poly vinyl chloride (PVC) /Calcium Carbonate (CaCO3) blends and their properties

Abstract The effects of micro and nanoscale calcium carbonate (CaCO3) particles on the mechanical properties of polyvinyl chloride (PVC) were investigated. Type of (PVC S5070) were used as the matrix in this study, hydrocarb 95T CaCO3 as a micro size particles, and SOCAL 312 CaCO3 as a nano size particles with different phr (0 wt%, 10 wt% and 20 wt%). The nano-CaCO3 particles were observed by FT-IR spectras. Nano- CaCO3 increased the tensile strength and affected the tensile strength of PVC more than micro-CaCO3 particles. The raise in hardness shore (A) is more considerable in nano-CaCO3 filled PVC compared to that of micro-CaCO3. TSDC test investigated that nano-CaCO3 in PVC samples have greater electrical resistance, and the maximum volume resistivity in micro-CaCO3 in PVC samples which mixed by ultrasonic. Thermal characterization of PVC samples were tested by DMA. Storage modulus and loss factor (tan δ) examined and showed that the storage modulus of PVC decreased as a function of temperature. The storage modulus can be increased concurrently by the presence of CaCO3. The glass transition of nano-CaCO3 sample mixed by ultrasonic has higher glass transition than other samples which mixed by normal mixing.

Keywords Calcium carbonate, Polymer composites, PVC, Micro-CaCO3, Nano-CaCo3.
