From Head-On to Headless: Understanding Shrimp Grading and Preferences
The seafood industry is quite competitive. The ability to distinguish and select the right grade of shrimp is not just a matter of culinary preference; it’s a strategic business decision. The demand for quality shrimp continues to rise, so shrimp businesspersons need to understand the nuances of shrimp grading to keep an edge in the market.
From head-on to headless, shell-on to peeled, each type and grade of shrimp carries specific attributes that impact not only the end product but also pricing and customer satisfaction. (And ultimately, profitability.)
Want to brush up on your skills at identifying shrimp grades? Here’s a guide.
The Basics of Shrimp Grading
Grading is so crucial in the seafood industry. In shrimp, grades are categorized according to size, appearance, and quality. Grading systems are important because they help buyers and sellers communicate better about the product, ensuring that everyone in the supply chain has a clear understanding of what is being traded.
Size Grading
Size is the most used grading system. Sizes are typically expressed in numbers, like 16/20 or 21/25. These indicate the shrimp count per pound, so a 16/20 grade means there are 16 to 20 shrimp in a pound. This ultimately means that the smaller the number, the bigger the shrimp. Bigger shrimp typically mean a higher price point.
To keep the grading system friendly to buyers, the counts are also translated into layman terms such as jumbo, large, medium and small. Those names deserve some caution: unlike the counts, the names are not regulated, so two retailers can put different labels on exactly the same size. Only the count is reliable.
Jumbo shrimp are graded 16/20. Anything larger carries a “U/” grade, where the U stands for “under”: U/15 means fewer than 15 shrimp to a pound, with U/12 and U/10 larger still and usually sold as colossal and extra colossal. These big boys are the largest shrimp available and are often prized for their impressive size and meaty texture. Jumbo shrimp are ideal for dishes where the shrimp are the star, such as shrimp cocktails or kabobs. Delish!
Extra large shrimp are 21/25 and large shrimp are 26/30. Large shrimp are versatile and commonly used in various dishes, from pasta to stir-fries. Restaurants typically order this size because of the balance between size and price point.
Medium shrimp are graded 41/50, with 31/40 sitting just above as medium large. These are smaller but substantial enough to hold their own in dishes like salads, curries, and shrimp tacos. They are more economical and are the typical choice for household dishes where the shrimp is part of a multi-ingredient dish.
Small shrimp are 51/60, and 61/70 is sold as extra small. These are often used in soups, stews, and dishes where the shrimp’s role is more about adding flavor than being the star. Small shrimp are the most affordable and are frequently used in bulk for large-scale food preparation.
Understanding these size categories and their corresponding counts is essential for making informed purchasing decisions that align with market demands and consumer preferences.
Quality Indicators
Beyond size, other quality indicators play a significant role in shrimp grading. Factors such as color, texture, and shell condition are carefully assessed. High-quality shrimp will have a consistent color, firm texture, and intact shells without any black spots or discoloration. These attributes are vital for ensuring that the shrimp meets the expectations of discerning customers, whether for retail or food service purposes.
Head-On vs. Headless Shrimp (HOSO vs. HLSO)
Head-on shrimp (aka HOSO) and headless shrimp (aka HLSO), on the other hand, influence appearance and flavor. Product form also matters when reading the counts above. By US convention, count grades are quoted headless shell-on, so a 16/20 means 16 to 20 headless shrimp to a pound. Head-on product in Mexico and Ecuador is commonly counted per kilogram instead, which is why the same shrimp can carry two different-looking grades on two different invoices.
Head-on shrimp are celebrated for their rich, intense flavor. The flavor comes from the head itself, where the natural “head juice” enhances the flavors of shrimp meat. HOSO shrimp is particularly popular in Asian and Mediterranean dishes, where both the visual impact and the robust taste are equally important.
Headless shrimp are favored for their convenience and versatility. The absence of the head makes HLSO shrimp easier to handle and quicker to prepare, which is a significant advantage in busy restaurant kitchens. On the flip side, these shrimp do not offer the same depth of flavor as their head-on counterparts. Still, headless shrimp have a clean, sweet taste that complements a wide range of dishes, such as pasta or stir-fries.
Sort-Rite’s Machines Do Both HOSO and HLSO
At Sort-Rite, our shrimp grading machines are designed to enhance your manufacturing processes by efficiently sorting head-on shrimp for HOSO production. Our de-heading machines seamlessly transform them into HLSO after processing. These machines ensure that each shrimp is handled precisely, maintaining the highest standards of quality and consistency throughout the sorting and deheading process.
Peeled, Undeveined (PUD) vs. Peeled, Deveined (PND) Shrimp
Aside from the heads, shelled grades also exist in the form of Peeled, Undeveined (PUD) and Peeled, Deveined (PND). These categories cater to different culinary needs and offer various benefits depending on the intended use.
Peeled, Undeveined (PUD) shrimp offer convenience and cost-effectiveness. The shell has already been removed, so these shrimp can be incorporated more seamlessly into various dishes, like salads or stews. However, leaving the vein intact can affect appearance and texture, which might be considered in high-end culinary applications. PUD shrimp are often used in dishes where the shrimp will be cooked further or where presentation is less of a priority.
Peeled, Deveined (PND) shrimp take convenience a step further by removing the vein (aka, digestive tract). This significantly improves the visual appeal of the shrimp, as well as the texture and overall eating experience. PND shrimp are particularly in demand in high-end restaurants, where dish presentation and quality are paramount. These are more expensive than PUD shrimp because of the extra effort and investment in adding convenience and improved aesthetics.
Choosing between PUD and PND shrimp depends on the specific needs of your clients’ kitchens and your production expectations. Both options offer unique advantages, and understanding these can help you provide the best possible product for your customers.
