Mathematical models were developed and evaluated for growth of psychrotolerant pseudomonads in chilled milk and in cottage cheese with cultured cream dressing. The mathematical models include the effect of temperature, pH, NaCl, lactic acid and sorbic acid. A simplified cardinal parameter growth rate model was developed based on growth in broth. Subsequently, the reference growth rate parameter...

The purpose of this study was to design and develop a low cost mobile fish vending unit in urban/municipality areas with proper waste disposal. The prototype model was designed and fabricated using locally available materials at a cost of Rs.52780/-. The main feature of this prototype is that its100 and 70 L insulated chilled crates; utility box; Cutting and processing area; storage of water an...

In this work the effects of common household practices such as chilling, freezing, and cooking on vitamin C retention in broccoli (Marathon cv.), as well as their influence on the release of sulforaphane upon enzymatic hydrolysis of glucoraphanin by the endogenous enzyme myrosinase, were investigated. When chilled at 6 degrees C and 95% R.H. for 35 d, broccoli showed a vitamin C and sulforaphan...

With the development of energy efficient building systems it has become very important to characterise various components as well as materials used for construction of buildings. The characterisation process involves evaluating the optical as well as thermal properties of materials for determining the energy efficiency, along with the conventional structural properties from structural strength ...

This paper describes methods for modeling the performance of transfer pumping interfaces used to connect open chilled water thermal energy storage tanks to closed chilled water systems. Indirect (heat exchanger) interfaces and direct interfaces are considered. Treatment of direct interfaces includes the use of energy recovery with centrifugal pumps serving as hydraulic turbines. Of the seven in...

As part of ASHRAE Research Project 1185, field data from the constant flow rate charging of a stratified chilled water storage tank with double-ring octagonal slotted-pipe diffusers serving a university chilled water system were compared with results of a transient axisymmetric computational fluid dynamics (CFD) model. Charge processes at flows near design flow rate and 50% of design were model...

The ability of phages to survive processing is an important aspect of their potential use in the biocontrol of Campylobacter in poultry production. To this end, we have developed a procedure to recover Campylobacter bacteriophages from chilled and frozen retail poultry and have validated the sensitivity of the method by using a characterized Campylobacter phage (i.e., NCTC 12674). By using this...

Changes in bacterial community composition and counts of chilled pork during storage at 4 °C were unraveled by culture-dependent method culture-independent method. Physical chemical analyses including drip loss, total volatile basic nitrogen (TVB-N), pH, surface color also performed to estimate its quality shelf life. A 37 phyla, 575 genera 843 species identified all samples high-throughput seq...
