“Soft shell” refers to the soft or pliable texture of the shrimp’s exoskeleton, which can be caused by stress or the natural process of the shrimp’s size change.
During this period, the shrimp is in a vulnerable state due to the fragility of its developing exoskeleton. After completing this process, which can last from 3 to 4 days, the shrimp acquires a new, harder exoskeleton and returns to its normal texture.
It is crucial to handle soft shell shrimp carefully to avoid damage and ensure they have adequate conditions to successfully complete the molting process.
This includes providing a stable and stress-free environment during this critical period of growth and development.
“Damaged pieces” refer to chunks or bits of shrimp that appear in the final product, especially during thawing.
This defect occurs when boxes of frozen shrimp, stored at -18°C, are damaged during handling or palletizing.
When boxes are thrown or handled roughly, shrimp on the surface can break or get damaged, resulting in broken pieces when the product is thawed.
The presence of damaged pieces not only affects the appearance and quality of the shrimp but can also compromise the integrity of the batch and customer satisfaction. To mitigate this issue, it is crucial to implement proper handling and management practices for boxes of frozen shrimp during storage and transportation.
Refers to shrimp that have been mishandled or improperly processed, resulting in physical damage or breakage of parts of the shrimp’s body.
This can occur during harvesting, transportation, or processing stages. Common signs include fragmented shells, broken appendages, or torn body segments.

See Our productsThe term “mixed species” refers to the situation in which shrimp of different species are inadvertently mixed during collection, transport, or processing. This mixing can occur due to improper practices in sorting, segregating, or handling during fishing, farming, or processing operations.
Mixed species shrimp can vary in size, color, texture, and flavor, which can result in inconsistencies in the quality of the final product and consumer expectations. This is especially relevant in markets where specific characteristics of certain shrimp species are valued.
To avoid the issue of mixed species, it is essential to implement proper management practices that include clear and effective separation of different species throughout all stages of the supply chain.
The “Neck Meat” refers to the part of the shrimp’s body where the head joins the thorax or abdomen. This area is characterized by a transition in texture and color compared to other parts of the shrimp. It is an important area both in terms of visual appearance and the quality of the shrimp’s meat.
Improper processing or handling can result in damage or discoloration of the meat in the tie, which affects the appearance and overall quality of the shrimp.
Therefore, it is crucial to handle this part of the shrimp carefully during all stages of handling, from harvest to final processing.
The expression “sand in the vein” refers to the presence of sand or gravel lodged within the digestive vein of the shrimp, which runs along its body.
This condition can occur when shrimp ingest sand or sediment particles from the environment in which they live. The presence of sand in the shrimp’s vein can affect the texture and taste of its meat, as these materials can interfere with the quality of the final product.
To prevent this problem, it is important to maintain farming and handling practices that minimize the shrimp’s exposure to sediments in their natural environment and ensure careful handling during all stages of processing to avoid contamination with sand or other unwanted materials.
The condition of “separated head” refers to the deterioration of the firmness of the shrimp’s head, which results in it detaching from the main body muscle.
This defect can occur due to various factors, such as improper processing, rough handling during harvesting, or prolonged storage.
When the shrimp’s head detaches from the muscle, it negatively affects the visual presentation of the product and may indicate inferior quality.
To prevent separated head, it is crucial to implement proper handling and storage practices that maintain the physical integrity of the shrimp from harvest to final marketing.
This includes maintaining appropriate temperatures, avoiding physical impacts, and ensuring careful processing to maintain the quality and freshness of the product.
“Separated shell” refers to the presence of the exoskeleton being lifted and separated from the flesh in some parts of the shrimp segment. This defect occurs when the shrimp has been mishandled during harvesting or the handling process. The lifted and separated exoskeleton from the flesh can indicate significant physical damage caused by rough handling, which compromises the visual quality and structural integrity of the shrimp.
To prevent separated shell, it is crucial to handle shrimp carefully from capture to final processing. This includes using appropriate handling and transportation techniques that minimize stress and physical damage to the shrimp.
Melanosis consists of a blackish coloration on the shrimp’s cuticle, caused by the enzymatic reaction of oxidized polyphenol.
This defect is also known as “black spots” or “black spot.”
Melanosis occurs in all shrimp species and activates approximately 3 hours after the shrimp’s death.
Although it does not affect food safety, it reduces the visual quality of the product and can negatively impact its marketability.
To prevent melanosis, treatments with antioxidants such as ascorbic acid and sulfites are used during the processing and storage of shrimp.
The appearance of red color on the shrimp’s head, known as “red head” or “cabeza roja,” is due to temperature loss in various processes, such as during harvesting, the transfer from the place of origin to the destination, and the time it takes to process the product.
This color change is indicative of the first stage of deterioration of the shrimp’s head and may be associated with the onset of decomposition.
The red coloring is the result of the oxidation of pigments and bacterial proliferation due to inadequate temperature conditions.
To avoid this defect, it is crucial to maintain the cold chain during all stages of handling and processing the shrimp, ensuring rapid and consistent cooling from harvest to final processing.
