Abstract Objectives The study was conducted to prolong the shelf life of freshly harvested pomegranate fruits and to find out its physiochemical properties during storage. Materials and Methods Pomegranate fruits of variety ‘Bhagawa’ were stored in 200, 300 gauge high-density polyethylene (HDPE) package, and silicone membrane modified atmospheric storage system at ambient conditions and 10°C. Gas composition inside the package, texture, color, and overall quality parameters were evaluated at these two storage temperatures. The physico-chemical properties such as total soluble solids, titratable acidity, ascorbic acid content, total, reducing, and non-reducing sugars, and physiological loss in weight (PLW) were also determined. Results In ambient storage, the shelf life of pomegranate fruit was 10 days, whereas in modified atmosphere packaging (200 gauge HDPE, 300 gauge HDPE, and silicone membrane system), the shelf life of pomegranate fruits was extended up to 60, 60, 25 days at ambient and 96, 96, 65 days at 10°C temperature, respectively. Conclusions Among the 200, 300 gauge HDPE package, and silicone membrane system treatments T1, T5, and T8, respectively, were found better with respect to all the sensory and quality parameters studied.

Abstract This study investigated groundwater quality collected from two industrial and residential locations in each of Lagos metropolis. Prescribed standard procedures of American Public Health Association were used to measure physico-chemical parameters of each of the groundwater samples which include pH, EC, DO, TDS, BOD, COD, anions (Cl−, NO3−, SO42−, PO43−) and heavy metals (Cu, Zn, Pb, Mn, Fe, Co, Cd and Cr). From laboratory analysis, measured physico-chemical parameters were within the permissible ranges specified by the WHO and NSDWQ except pH, TDS, EC, Pb, Mn and Fe for groundwater samples from industrial locations and pH, Pb, Mn and Fe for residential locations. Higher concentrations of TDS and EC reported for groundwater samples from industrial locations were attributed to heavy discharge of effluents from industrial treatment plants as well as dissolution of ionic heavy metals from industrial activities of heavy machines. Statistical Pearson’s correlation revealed physico-chemical parameters of water quality to be moderately and strongly correlated with one another at either p  < 0.05 or < 0.01.

Resistant starch is known to impart a number of health benefits to consumers. It is therefore desirable to increase the content of resistant starch in popular foods such as yoghurt. The current research investigated the effect of cassava resistant starch synthesized by heat-moisture treatment of starch from I92/0057 cassava variety on physico-chemical properties and sensory attributes of yoghurt. Cassava starch rich in resistant starch was incorporated into yoghurt in the proportions of 0, 0.1%, 0.5% and 1%. Corn starch (0.6%) was used as control. Yoghurt was stored at 4oC for 21 days and the effect of starch modification on resistant starch content, viscosity, syneresis, total solids, acidity, lactic acid bacteria count and sensory properties were determined on weekly basis. Applying cassava starch rich in resistant starch into yoghurt in the proportions of 0.5% and 1% had significantly higher (p≤0.05) resistant starch content of yoghurt reaching 3.40 g/100 g and 5.58 g/100 g on day one and 1.92 g/100 g and 4.47 g/100 g on day 21, respectively. There was a significant correlation (p≤0.05) between resistant starch concentration and the physico-chemical properties of yoghurt. Yoghurt treated with 1% resistant starch enriched cassava starch had the highest viscosity during cold storage which was determined as 2721.5 mPa s, mPa s, 2650.0 mPa s and 1034.5 mPa s at day 1, day 7, day 14 and day 21 respectively and it had the least syneresis (22.25%). Addition of cassava starch rich in resistant starch significantly increased (p≤0.05) the total solids content of yoghurt but did not significantly (P>0.05) change the sensory properties of yoghurt. The application of 1% of resistant starch enriched cassava starch as yoghurt thickener produces significant quantity of resistant starch in yoghurt with acceptable sensory and physico-chemical properties.

The accumulation of salts in the soil produces conditions that affect the growth of most crops. Currently, soil amendments have been used to improve the texture and chemical & biological reactions of the soil. The objective of this work was to simulate the transport of sodium, potassium, calcium and magnesium in columns of saline soil through the use of organic and chemical amendments. Saline soil samples of the municipality of Tlahuelilpan, Hidalgo state, Mexico were studied. Compost, vermicompost, phosphogypsum and malting barley husk were used as amendments. The results showed that the highest metal element removal was obtained with the combined treatment of vermicompost at 4 % and phosphogypsum at 2 % (V4FY2) (59 %). Improvements in soil physico-chemical properties were also observed. These findings indicated that the combination of organic and chemical amendments promotes the leaching of metals, (mainly sodium). Therefore, the amendments evaluated in this study can be a good alternative for the remediation and improvement of saline soils.

The study aims to study the effect of irrigation water characteristics from different sources (i.e., fresh water and agricultural drainage water) on some chemical properties of the soil (soil pH, soil electrical conductivity “ECe”, sodium adsorption ratio “SAR”, cations exchange capacity “CEC” and exchangeable sodium percentage “ESP”).Therefore, water samples were collected from 15 different sites of the Bahr Mouise canal and likewise from the Bahr El-Baqar drain, which are located in Sharkia Governorate, Egypt. In parallel with water sampling, soil samples were taken from the same areas that are irrigated with these waters (i.e., Bahr Mouise canal and Bahr ElBaqar drain). Soil and water samples were analyzed.The results indicated that the irrigation water sources (i.e., Bahr Mouise canal and Bahr El-Baqar drain) were affected on the different of the chemical characteristics of soil. The pH values of the soil that irrigated with Bahr Mouise canal water were ranged from 7.62 to 8.35 with an average 8.01±0.21, while pH values of the soil that irrigated with Bahr El-Baqar drain water were ranged from 7.99 to 8.56 with an average 8.27±0.16. The EC values of the soil that irrigated with Bahr Mouise canal water were ranged from 0.61 to 3.86 dS/m with an average 1.23±1.00 dS/m, while ECe values of the soil that irrigated with Bahr El-Baqar drain water were ranged from 1.82 to 2.67dS/m with an average 2.35±0.30 dS/m. Regarding sodium adsorption ratio (SAR), the SAR values average in soil that irrigated with Bahr Mouise canal (ranged from 0.84 to 7.65 mmolc/l with an average 2.12±1.91 mmolc/l) were less than the SAR values average in soil that irrigated with Bahr El-Baqar drain (ranged from 2.49 to 3.79 mmolc/l with an average 3.27±0.38 mmolc/l) with statistically significant differences between them (p-value < 0.05). In addition, the results showed that the CEC values in the soil that irrigated with Bahr El-Baqar drain (ranged from 49.66 to 71.37 cmolc/kg soil with an avera
