Influence of duration and temperature of infusion on the heavy metal
contents of some groups of tea in Nigeria
- Abstract: Consumption of tea has been recommended not only for its taste and aroma but also for its medicinal importance, and these factors may contribute to public health concerns. The physicochemical characteristics of tea groups (green, black, and medicinal tea) were investigated using standard procedures. 2 g of each tea group and type were infused for 10 min at 60 and 80C, and the extract was dig...

Major anthocyanin quantification, free radical scavenging properties and
structural identification in Cymbopogon giganteus extracts
- Abstract: Anthocyanin-based colorants are highly appreciated by the food industry for their lower toxicity. However, in Burkina Faso, very little scientific information is available on potential sources of anthocyanins, despite significant progress in plant studies. This scientific report is the first to focus on anthocyanins of Cymbopogon giganteus from Burkina Faso and aims to valorize them for thei...

Filler characterization, mechanical properties, x-ray diffraction and
- Abstract: Starch fillers were extracted from three plant sources namely amora tuber, Tacca lentopeteloides; sweet potato, Ipomoea batatas; yam starch, Dioscorea rotundata and their particle size, pH, amylose, and amylopectin percentage decomposition determined accordingly. The starch was introduced into natural rubber in liquid phase (through gelatinization) by the latex compounding method and compoun...

Determination of caffeine content of Nensebo coffee beans Southern
Ethiopia, using ultra violet-visible (UV/V) is and high performance liquid
chromatography (HPLC) methods in Ethiopia
- Abstract: The main objective of the study was to determine caffeine content of coffee beans (Coffee arabica) collected from Nensebo district, West Arsi Zone, Oromia Region using ultra violet-visible and high performance liquid chromatography methods. The coffee beans were purchased from coffee supplying farmers cooperatives in Nensebo district (namely Tulu Gola, Habera, Refisa, Nensebo Chebi and Melka...

Physicochemical and nutritional properties of Syzygium cumini (L.) skeels
fruits grown in varied microclimates in Kenya
- Abstract: Wild fruits contribute significantly to food security, thus becoming an important global discussion. This study evaluated the physicochemical and nutritional properties of Syzygium cumini (L.) Skeels fruits from two microclimates in Kenya as essential contributors to the human diet. Analysis was done using standard methodologies including the use of inductively coupled plasma - optical emiss...

Nutritional, biochemical and phytochemical characterization of seeds and
seed oil of pumpkins (Cucurbita maxima) grown in Malawi
- Abstract: Pumpkin is a significant part of dish when in season in Malawi. In this study, the proximate composition, physicochemical and phytochemical properties were determined from pumpkin seed and oil. The Cucurbita maxima seed proximate compositions (%) were dry matter (97.580.26), crude protein (32.470.15), ash (7.380.05), crude fat (46.390.06), crude fiber (12.290.17) and carbohydrate (4.180.21),...

Assessment of proximate and physicochemical properties of crude palm oil
from south-west and South-south Nigeria
- Abstract: Crude palm oil is most worlds widely used oil, due to its nutritional and economic advantages. The proximate and physicochemical properties of fifty samples from local mills in Southern Nigeria were analyzed to determine their applicability as food and industrial usage applying standard procedures. The obtained results were: Moisture content (1.51 to 2.46%), ash content (0.30 to 0.50%), crud...

Dichlorodiphenyltrichloroethane (DDT) and its metabolites in house dust,
soil and selected food crops from indoor residual sprayed areas of Apac
and Oyam Districts, Uganda
- Abstract: Dichlorodiphenyltrichloroethane (DDT) levels and its metabolites are reported in 75 soil and 75 vegetable samples from the vicinity of homesteads sprayed with DDT during indoor residual spraying (IRS) pilot exercise, carried out in 2008 in Apac and Oyam districts, Uganda as a measure to control malaria. The samples were randomly and conveniently collected in 2020 from selected villages of th...

Excess refractive indices and validation of mixing rules using binary
mixture of methyl laurate + Pentan-2-ol at various temperatures (298.15,
303.15, 308.15, 313.15, and 318.15K)
- Abstract: Refractive index is a characteristic parameter of fluids with numerous industrial uses. The values of refractive indices of many pure liquids are known or can be found in the literature. However, when experimental values of the liquid mixtures are not available then refractive indices of binary mixtures and multi-component liquids are frequently assessed from the pure constituents using mixi...

Evaluating the potentials of complexing agents in multi-metal extractions
using
4,4´-(1e,1e´)-1,1´-(Ethane-1,2-Diylbis(Azan-1-Yl-1ylidene))Bis(5-Methyl-2-Phenyl-2,3-Dihydro-1h-Pyrazol-3-Ol)
(H2BuEtP)
- Abstract: Heavy metals toxicity has led to the continuous study of new and efficient methods for their removal from the environment. Solvent extraction method was used to study the potentials of the auxiliary complexing agents Ethylenediaminetetraacetic acid (EDTA), Oxalate (C2O42-), Thiocyanate (SCN-) and Tartrate (C4H4O62-) ions in the simultaneous extraction of Cadmium, Iron, Nickel and Lead from a...
