Abstract:

Coconut water is popular worldwide, mainly because of its pleasant sensory characteristics, nutritional value and low calorie density. However, coconut water is a highly perishable product due to the presence of enzymes such as peroxidase and polyphenoloxidase, which cause undesirable changes in colour, and also because of its susceptibility to microbial spoilage. The use of chemical additives has been adopted by the industry with the intent of increasing product shelf life. In this study, the efficiency of the preservatives potassium sorbate and sodium metabisulphite was assessed using a Cent

Abstract:

Ultrafiltration (UF) has been presented as an alternative to chemical disinfection to obtain safe drinking water, for its ability to remove microbiological contamination. Hollow-fiber UF membranes are designed as an effective barrier to microorganisms, for their high manufacturing integrity and for the ‘potting’ method adopted to seal fibers to the feeding/extraction manifold. While the main advantage over chemical disinfection is the drastic reduction of disinfection-by-product (DBP) formation, some chemicals are still required to control fouling and related sanitary risks.

Abstract:

Abstract Quality assurance (QA) and quality control (QC) data are required in order to have confidence in the results from analytical tests and the equipment used to produce those results. Some AOAC water methods include specific QA/QC procedures, frequencies, and acceptance criteria, but these are considered to be the minimum controls needed to perform a microbiological method successfully. Some regulatory programs, such as those at Code of Federal Regulations (CFR), Title 40, Part 136.7 for chemistry methods, require additional QA/QC measures beyond those listed in the method, which can also

Abstract:

The World Health Organization (WHO) recently produced draft guidelines for safe recreational water environments. The microbiological standards proposed in the guidelines are expected to over-estimate the degree of water quality required to provide given levels of public health protection. The WHO standards were obtained by means of a risk assessment which featured a dose-response model derived from a series of randomised controlled trials. The trials have many strengths but biases and problems with statistical analysis are likely to have led to over-estimation of the risks from bathing in the

The present study aims at the microbiological analysis of export oriented frozen fishes, namely, Jew fish, Tongue Sole fish, Cuttle fish, Ribbon fish, Queen fish, and fish processing water and ice from a view of public health safety and international trade. Microbiological analysis includes the determination of total viable aerobic count by standard plate count method and enumeration of total coliforms and fecal coliforms by most probable number method. The presence of specific fish pathogens such asSalmonellaspp. andVibrio choleraewere also investigated. The TVAC of all the samples was estima

The efficiency of membrane filtration (MF) techniques and most probable number (MPN) tube dilution assays for the bacteriological analysis of homogenized oyster and mussel meat was compared. Tests were done on naturally contaminated shellfish and on homogenates seeded with sewage. Digested homogenates (5% trypsin for 20 min at 37°C) were prefiltered (pore size 5 um) and then filtered (pore size 0.45 µm) for MF counts. Undigested homogenates and dilutions were inoculated into tubes with growth medium for MPN tests. Homogenates (with or without trypsin) were used directly in a toplayer method fo

Background: Global statistics show that over 1.2 billion people do not have access to potable water and 70% of Nigerians lack access to potable water. Non-availability and/or lack of access to potable water predispose people to preventable life-threatening conditions. This study assessed the physical, chemical, and microbiological quality of sachet and bottled water to generate evidence for planning, policy, and intervention.Methods: The study was a cross-sectional analytic study of the quality of packaged (sachet and bottled) drinking water obtained from consumer households.

Abstract:

Agba Dam, which is an important source of raw water used in treatment of water for supply of potable water in Ilorin Metropolis, was evaluated for presence of bacteria, pollution level and potability. Samples were collected from four points along the course of the dam. Bacteria isolated included Enterobacter aerogenes, Salmonella enteritidis, Shigella dysenteriae, Proteus vulgaris, Enterobacter cloacae and Escherichia coli using selective media and Microbact identification system. The pH of the water samples ranged between 7.51-7.90, temperature ranged between 22-29 °C, total hardness ranged b

Abstract:

Recent Hungarian water quality monitoring system uses 300 sampling points to classify surface waters into three quality categories that are mainly reflecting the viewpoints of different water uses. The suggested new system halved the number of the sampling points, while sampling frequency increased. The new system also includes metals, microbiological indices and organic micropollutants. The almost 70 constituents of the system are grouped into five water quality categories. The assessment is based on the value of 90 % relative frequency. The suggested new system is going to be introduced in p

Abstract:

The Alaknanda River is one of the main rivers of Alaknanda sub- system which bubbles out from Alkapuri Glacier. Water quality of the sacred river Alaknanda was evaluated by microbiological and physico- chemical methods. The sampling was undertaken from various sites of lower stretches, including Rudraprayag (530 m a.s.l.), Srinagar (560 m a.s.l.) and Deoprayag upstream (457 m a.s.l.) on the river Alaknanda. A perusal of the data revealed that total viable count (CFU.ml-1) was recorded minimum (25,850 CFU.ml-1) in winter season and then it increased during summer (45,730 CFU.ml-1) and attained
