Evaluation of the Effect of Ethephon in Postharvest Tomato (Lycopersicon esculentum)
No full textAims: The aim of this study is to determine the effect of applying ethephon on postharvest tomato.
Study Design: Completely Randomized Design (CRD).
Place and Duration of Study: The study was conducted in the laboratory of the Department of Applied Food Science and Nutrition, Department of Food Processing and Engineering, Department of Applied Chemistry and Chemical Technology of Chittagong Veterinary and Animal Sciences University, Chittagong, Bangladesh. It was conducted for a period of six months from 1st January, 2018 to 30th June, 2018.
Methodology: TSS (Total Soluble Solid) was determined by using hand refractometer, proximate composition by standard AOAC method, vitamin C and β-carotene by UV-spectrophotometric method, sodium and potassium by flame photometric method, titratable acidity, calcium and magnesium by titremetric method. To compare differences in control and treated group, significant difference was considered at the level of P<0.05.
Results: Ethephon treated tomatoes ripen quickly with attractive surface color and had shorter shelf life than non-treated tomatoes (control). Physico-chemical properties including total soluble solid and titratable acidity increased significantly (P<0.05) in treated group (4.66±0.57°B; 0.32±0.01% respectively) than control (3.33±0.57°B; 0.28±0.01% respectively). Moisture content also significantly (P<0.05) increased in ethephon treated tomato (94.15±0.27g/100g) than non-treated (85.54±0.23g/100g). But significantly lower amount of carbohydrate, ash, crude fiber were observed in artificially ripened tomato by ethephon (2.5±0.45g/100g; 0.51±0.02g/100g; 0.82±0.03g/100g respectively) than naturally ripened (3.7±0.26g/100g; 0.59±0.01g/100g; 0.90±0.01g/100g respectively). Apparently protein and fat content were found insignificantly less amount in artificially ripened tomato by ethephon. The significant lowest concentration of vitamin C and β-carotene were observed in ethephon ripened tomato (16.65±0.01mg/100g; 413.33±1.15μg/100g respectively). Mineral contents of ethephon treated tomato (Na 3.65±0.47mg/100g; K 199±1.00mg/100g; Ca 4.75±0.07mg/100g; Mg 8.57±0.19mg/100g) found significantly (P<0.05) fewer amounts than control tomato (Na 3.96±0.01mg/100g; K 213.67±0.57 mg/100g; Ca 5.57±0.15mg/100g; Mg 9.96±0.04mg/100g).
Conclusion: Application of ethephon on postharvest tomato hastens ripening time and physico-chemical properties but reduces shelf life and nutritive value of tomato
Physiochemical and Microbiological Analysis of Drinking Water in Chattogram City, Bangladesh
No full textChattogram is the second most populated city in Bangladesh. This port city faces a serious threat mainly due to the lack of safe drinking water. This study was conducted for determining drinking water quality of groundwater sources in Chattogram city. The study was performed in the BCSIR laboratory, Chattogram. It was carried out for a period of six months from 1st July, 2018 to 31th December, 2018. Total six water samples were collected from three different locations (Baluchora, C&B colony and Khulshi area). Each sampling location consists of two separate sampling points. Physicochemical parameters of the collected samples like Temperature, pH, Electrical Conductivity (EC), Total dissolved solid (TDS), Hardness, Turbidity and concentration of Cl, As, Mn, Fe, Pb, Cr and Cd were examined. Microbial parameters like Total Coliform (TC) were also measured. All the analyzed parameters compared with BSTI and WHO drinking water quality standards to understand the overall ground water quality status of the study area. The results reveal that water samples in almost all locations were contaminated with microbial contamination and that the range of physico-chemical parameters was not adequate for consumption. Preliminary treatments like boiling, filtering etc are required before using groundwater for drinking and the necessary measures must be taken for a safe alternative source of drinking water
