How important is the ice in preserving seafood products?

Cold preserves and maintains the quality of numerous products and protects them against premature spoilage. Ice is a reliable coolant that has been put to good use for centuries for cooling fish and seafood both on and off shore.

What does ice do to fish?

The layer of ice that forms on top of a lake, pond, river, or stream provides some insulation that helps the waterbody retain its heat. Because warm water sinks in very cold freshwater, fish in these water bodies often gather in groups near the bottom.

Why is chilling important in preserving fish?

Chilling is the process of cooling fish or fish products to a temperature approaching that of melting ice. The purpose of chilling is to prolong the shelf-life of fish, which it does by slowing the action of enzymes and bacteria, and the chemical and physical processes that can affect quality.

What is icing in fish processing?

In order to maintain optimum fish quality, fish, once caught should be chilled to 0ºC as quickly as possible. Ice chills fish by surface heat transfer either by direct contact between fish and ice or by cold melt water running over the fish surface.

What is the difference between chilling and freezing?

Freezing & Chilling at a glance In the food industry, freezing usually refers to deep freezing, or lowering the temperature of product below -18°C. In contrast, chilling refers to the rapid cooling of a food product from its manufacturing temperature down to refrigerated or cold temperatures, usually from 2 to 4°C.

What are the advantages of Cook freeze?

– Improved safety – as all bacterial growth is halted by freezing of food, our cook-freeze system is intrinsically safer than the cook-chill process. – Less temperature sensitive – because the meals are frozen, they are much less susceptible if exposed to minor short term changes in ambient temperature.

What is the ideal temperature for chilled fish?

The International Institute of Refrigeration recommends a storage temperature of -18°C for lean fish such as cod and haddock and -24°C for fatty species such as herring and mackerel. The code also recommends that for lean fish intended to be kept in cold storage for over a year, the storage temperature should be -30°C.

What are the three methods of storing iced fish?

Methods of using ice Two methods are used to store fish with ice. Bulking is the layering of fish and ice, usually in a fish hold, though it can be done in a large, permanently fixed, insulated ice box. Boxing is the layering of fish and ice in specially made boxes.

Why are fish and fishery products hazards and controls?

Processors of fish and fishery products will find information in this guidance that will help them identify hazards that are associated with their products, and help them formulate control strategies. The guidance will help consumers and the public generally to understand commercial seafood safety in terms of hazards and their controls.

What are the production costs of fishery products?

In Table 4.2 some production costs per 1 kg of finished products for various types of fishery products are listed. The data appearing in Table 4.2 are only indicative and refer to the place and year where they were collected. It should be taken into account that costs per unit depend on installed capacity and production level (see Chapter 3).

What does FDA guidance on fish and fishery products mean?

This guidance represents the agency’s current thinking on the hazards associated with fish and fishery products and appropriate controls for those hazards. It does not create or confer any rights for or on any person and does not operate to bind FDA or the public.

What should seafood processors do to comply with new regulations?

Seafood processors that are in the process of developing or revising HACCP systems to be in compliance with the new regulation, should first review the regulation to determine its requirements. Secondly, they should review the Guide for help to identify hazards and formulate control strategies.
