Study Notes
Post-Harvest Handling of Aquatic Products
- Squids and cuttlefish require thorough cleaning and storage at low temperatures to maintain freshness.
- Chilling in crushed ice or ice slurry is an effective method to preserve the freshness of squids and cuttlefish.
Handling Seaweeds
- Freshly harvested seaweeds for local consumption should be washed in clean seawater and packed in baskets with banana leaves as covering.
Fish Processing and Chilling
- Fish is highly perishable and requires proper handling from harvesting to consumption.
- All stakeholders, including fishermen, middlemen, and consumers, play crucial roles in maintaining fish freshness.
- Lowering the temperature through chilling, refrigeration, and freezing is essential to preserve fish quality.
- Chilling reduces temperature to between -1.1°C and 0°C, slowing down spoilage but not stopping it.
Methods of Chilling Fish
- Icing (wet ice) is the most common and effective method of chilling fish in the fishing industry.
This quiz provides a summary of Chapter 3 from the book 'Chilling Fish Processing Technology in the Tropics' by J. Espejo-Hermes (2004), focusing on the proper cleaning and storage techniques for squids, cuttlefish, and seaweeds. Learn about the importance of chilling fish and maintaining freshness in aquatic products.
