This study aimed to characterize the honeys of Babors Kabylia through sensory, melissopalynological and physico-chemical parameters. Thirty samples of honey produced in this region were collected over a period of two years and analyzed. All the samples presented physico-chemical parameters in conformity with legislation on honey quality, with few exceptions, linked mainly to beekeeping management. The pollen spectrum revealed a great diversity with 96 pollen types. The main pollen types were spontaneous species as Fabaceae (Hedysarum, Trifolium, Genisteae plants), Asteraceae plants, Ericaceae (Erica arborea L.) or Myrtus and Pistacia. The sensory properties of samples showed a high tendency to crystallization, the colors were from white to brown, but most of them had gold color. Smell and odor corresponded mainly to vegetal and fruity families and in taste perceptions besides sweetness highlighted sourness and saltiness notes. Seventeen samples were polyfloral, one was from honeydew and twelve were monofloral from heather, genista plants, sulla, blackberry or Asteraceae. Heather and the honeydew samples showed the darkest color, the highest electrical conductivity and phenol and flavonoid content. A statistical analysis based on the most representative pollen types, sensory properties and some physico-chemical components allowed the differentiation of honey samples in terms of botanical origin.

Aims: The objective of this study was to evaluate the effect of dilution ratio and pasteurization on physico-chemical parameters of Saba senegalensis pulp in the context of its recovery. Study Design: The experimental set-up was of a completely randomized design. Place and Duration of Study: This study was carried out in the Department of Food Science and Technology, at the Laboratory of Food Biochemistry and Tropical Product Technology (BATPTL) of Nangui Abrogoua University, Abidjan, Côte d'Ivoire, between June and August 2019. Methodology: The pulp collected from the fruit was diluted according to the following pulp/water ratio (RPW; v/v): 1:0.5; 1:1 and 1:1.5 and pasteurized at 75°C at different times (5 min, 10 min and 15 min). The pH, titratable acidity (TA), Total soluble solid (TSS), vitamin C, β-carotene and the colour were determined on the different samples. Results: The results obtained during this study showed that all the physico-chemical parameters evaluated, except pH, are affected during dilution while during pasteurization only vitamin C and β-carotene are affected. During the respective dilutions, 50%, 62% and 66% of the vitamin C concentration decreased as well as 53%, 74% and 76% of β-carotene. It also led to a decrease in total soluble solid (TSS) of 32%, 50% and 59%. Following the pasteurization of each diluted pulp12%, 45% and 50% on average of the vitamin C are lost at the respective pasteurization time  (5 min, 10 min and 15 min respectively). For β-carotene the content decreases (50%) within the first 5 minutes and remains constant during the last 10 minutes of pasteurization. Conclusion: During Saba senegalensis fruit processing into nectar, dilution and pasteurization factors must be considered in order to ensure the physico-chemical quality of the beverage. The physico-chemical characteristics were more affected during dilution than in pasteurization.

The water samples collected from four localities of the middle course of the Zapadna Morava River during 2020 were analyzed via the selected physico-chemical parameters with the aim to estimate the quality of surface water. According to the results of selected physico-chemical parameters (pH, conductivity, dissolved oxygen, chemical oxygen demand, biochemical oxygen demand), analyzed surface water show a good chemical status, while the values of nutrient content (nitrate, nitrite, ammonium ion, total phosphorus) indicated the poor chemical status especially at the locality 4 probably due to the outflow of wastewater from the city of Čačak as well as from the influence of the polluted water of the Čemernica River.

Abstract Cyanobacterial blooms occur frequently in artificial lakes, especially in water reservoirs with small retention exposition to anthropopressure. The abundant occurrence of cyanobacteria is accompanied by danger of oxygen imbalance in the aquatic environment and the secretion of toxins that are possible threat to human health and life. Cyanobacterial cell growth depends on a number of physical (temperature, light exposure), chemical (pH, concentration of compounds containing nitrogen and phosphorus) and biological (the presence of other organisms) factors. This paper presents the results of the analysis of water from reservoirs located in southern Wielkopolska region (Pokrzywnica-Szałe, Gołuchów and Piaski-Szczygliczka). Some important physico-chemical parameters of water samples taken from investigated reservoirs as well as cyanotoxins concentration were determined. Furthermore, the cyanobacterial species were identified. There was also an attempt made to correlate the water parameters with the cyanobacteria development and cyanotoxins production. On the basis of the results obtained in the analyzed season, it can be concluded that water from Pokrzywnica and Gołuchów reservoirs was rich in nutrients, hence the intense cyanobacterial blooms and cyanotoxins in water were observed

Through the practice of irrigation, surface water reservoirs (SWRs) contribute to the socio-economic development and food production activities of populations in Sub-Saharan Africa (SSA). However, they tend to dry up prematurely. One solution to circumvent these irrigation water shortages is to ensure their conjunctive use with groundwater. The objective of this study is to better understand the contribution of SWRs to groundwater recharge and to determine if groundwater may be considered as a complementary local resource for irrigation. The study was carried out on two watersheds in Burkina Faso, Kierma and Mogtedo. The spatiotemporal analysis of piezometric and SWRs level records coupled with physico-chemical analyses of water was used to characterize exchanges between SWRs and groundwater. The regional groundwater recharge at the scale of the watersheds was assessed. At the SWRs scale, a water balance methodology was developed and used to estimate focused recharge. The results show that SWRs interact almost continuously with groundwater and contribute focused recharge. The magnitude of this recharge is a function of the geological context and the sediment texture of the SWRs. It is estimated at 5 mm/day in Kierma and 4 mm/day in Mogtédo. These values are higher than the natural recharge estimated at 0.2 mm/day in Kierma and 0.1 mm/day in Mogtédo. Additionally, the values of hydraulic conductivity are between 0.01 and 2 m/day in Kierma and between 1 × 10−4 and 0.2 m/day in Mogtédo. These conductivities could allow pumping in large-diameter hand-dug wells with a significant yield between 0.5 and 120 m3/day in Kierma and between 0 and 10 m3/day in Mogtédo to palliate the early drying up of the SWRs.

Physico-chemical parameters that influence dough attributes and baking quality were investigated in single and composite flours. Considerable variation in the starch and protein components was observed in the different formulations of wheat and substituent flours. Incorporation of kurakkan, sorghum, or manioc flour increased gelatinization temperature, viscosity, and amylose content irrespective of the extent of substitution. Although increases in amylose content were within tolerable limits, changes in gelatinization temperature and viscosity characteristics necessitate use of chemical agents and modified technology for preparation of acceptable products. A marked reduction in protein content was revealed in manioc-wheat composites, wherein nutritive fortification should comprise an additional requisite.
