More so, my beloved wife Lillian Awuor for accepting a lonesome life while I pursuit academic accomplishment. ii Abstract The main aim was to establish optimal storage conditions for fresh tilapia fillets, by determining its shelf life from the sensory and microbiological evaluation, as well as monitoring its physical-chemical properties. With this intent, Nile tilapia (Oreochromis niloticus) farmed in recirculation aquaculture system was filleted and packaged in 100% air and 50% CO2: 50% N2 MA prior to storage at different temperature; 1˚C and -1˚C. Initial samples from filleting (control d0) were also evaluated for comparison.
  • Cold Chain in Seafood Industry

    Cold Chain in Seafood Industry

    COLD CHAIN IN SEAFOOD INDUSTRY Alex Augusto Gonçalves1, Ph.D and Francisco Blaha2, MSc. Abstract: When seafood is freshly caught eating quality is high, but over time quality will deteriorate and eventually will become unsuitable for consumption. Maintenance of the cold chain and careful handling are a fundamental part in minimizing seafood spoilage. The cold chain in seafood industry is a temperature chain and begins once the seafood is caught. From the quality and regulatory perspective fresh seafood means that has been stored at 0°C and for frozen seafood it means –18°C or colder (from the sea to the consumer). The cold chain is broken every time the temperature of the seafood rises above 1°C. Fluctuations in the cold chain increases quality loss, these losses cannot be reversed by any means after the event. There are many avoidable and unavoidable occurrences that cause fluctuation in the cold chain. Good chilling and/or freezing practices on board harvest vessels are a condition sine qua non for maximizing the best possible quality of all seafoods. Best practices on seafood handling and the minimization of temperature fluctuations are paramount for seafood distributed under refrigeration (i.e., chilled and/or frozen) to maintain its quality and maximize its shelf–life. The present chapter addresses some of the developments in seafood cold chain under four mainly headings: i) cold chain in seafood industry; ii) selected aspects of refrigeration (chilling and freezing) process (including equipment and storage conditions); iii) safety and shelf–life issues in seafood cold chain; iv) regulation and legislation. 1.

  • Design and Fabrication of Slurry Ice Generator

    Design and Fabrication of Slurry Ice Generator

    International Journal for Research in Engineering Application & Management (IJREAM) ISSN : 2454-9150 Vol-03, Issue-07, Oct 2017 Design and Fabrication of Slurry Ice Generator Vikas K Tawde Department of Mechanical Engineering, Vidyavardhini’s College of Engineering and Technology, Vasai, Mumbai, India. Abstract: This paper proposes the Design and Fabrication of a slurry ice generator which produces slurry ice, a mixture of water and ice wherein the ice is in the form of spherical crystals of about 0.1 to 1mm in diameter. It provides 3 to 4 times better cooling compared to flaked ice owing to larger heat transfer area. Slurry ice finds application in food preservation especially in the fishing industry. In India, flaked ice is used for seafood preservation. Introduction of slurry ice in the fishing industry will result in better quality of produce. This paper is focused on the design calculations and the selection of proper components wherein the conventional ice scraper is replaced by an Archimedes’ screw to eliminate the use of circulation pump. The refrigeration system works on a simple vapor compression cycle. Ice crystals are formed on the inner surface of shell and coil type evaporator, and, scraped by the Archimedes’ screw. Keywords — Ice Slurry, Archimedes’ screw, Newtonian, pumpability, R134a, isentropic, coefficient of performance. and heat exchangers. Ice slurries can also be pumped through NTRODUCTION I. I veins and lungs to lower temperature much faster. Because of The fishing industry in India makes use of flaked ice for Pumpability slurry ice with nozzles can be used in fire preservation.

  • A Revolution in Food Preservation Why Flake Ice Doesn’T Work Anymore…

    A Revolution in Food Preservation Why Flake Ice Doesn’T Work Anymore…

    A REVOLUTION IN FOOD PRESERVATION WHY FLAKE ICE DOESN’T WORK ANYMORE… Modern consumers have become extremely aware of how important food quality is to their nutrition and way of living. Therefore, they continue to demand food that is fresh, of higher quality, and delivered quickly to the market. This puts seafood harvesters, aquaculture producers and processors in a position where they need to adapt, but don’t have the right means to preserve harvest for long periods of time. Although it is the cheapest option, flake ice cannot do the job anymore as it: • damages the product surface and causes breakage • leads to shrinkage and weight loss The increasing demand • and creates an environment for bacteria to cause for better and fresher food quicker product spoilage. puts an even stronger pressure on aquaculture All that decreases the product value and minimizes the producers and food profit margins aquaculture manufacturers and food processors. processors need to scale in the long run. …AND SLURRY ICE DOESN’T SOLVE THE PROBLEM EITHER Liquid ice solutions, like slurry ice, use small ice crystals to absorb heat from fresh products. Usually, they have good flow properties and are easily distributed. As slurry ice creates a uniform contact with the product surface, it’s often considered an improvement over flake ice. However, this is only partial. Slurry ice still lacks the deepest level of cooling transfer to products, which may lead to spoilage. Sometimes, this results in seafood harvesters, aquaculture producers and processors to use additives in the preservation process, which is the opposite of the consumer demand for more organic, preservatives-free products.

Sea water is fish processing units still uses conventional methods, so there also not disturbed by the dry season as in fresh water, when the are still many shortcomings and weaknesses that have an dry season is very difficult to find and the price is also much impact on the quality of the fish that is stored. The purpose of more expensive. this study is to produce a slurry ice machine design with an evaporator temperature reaching -5°C, a production capacity of In slurry ice as a fish cooler there is no air between the fish and 1.3 tons according to the standard and put forward an ice, so that the cooling of the fish becomes faster because of ergonomic, safety factor as well. The results showed that the direct contact with the surface and cavities in the fish is larger target temperature of the slurry ice machine evaporator reached and slower bacterial growth makes an extension of the -5°C was reached, with a temperature achievement of -5.8°C freshness of the fish.
