Is Your Scallop Treated? How to Spot a "Wet" Scallop and Why It Matters

Intershell is committed to providing the highest quality, naturally processed seafood products. Unlike many other seafood processors, Intershell does not use any chemical additives, including STPP, in their scallop processing.

There isn't a single, definitive statistic on the percentage of scallops treated with STPP (Sodium Tripolyphosphate). However, several studies and reports indicate that a significant portion of the scallop market, particularly in the United States, involves scallops treated with this additive.

Here are some key points to consider:

• STPP Treatment is Common: Many commercial scallop processors use STPP to enhance the scallops' moisture content, texture, and shelf life.
• Consumer Awareness Varies: While many consumers are aware of food additives, the specific use of STPP in scallops may not be widely recognized.
• Regulatory Oversight: The use of food additives, including STPP, is regulated by government agencies like the FDA. These agencies establish guidelines to ensure safety and proper labeling.  
• Consumer Preference: Some consumers may prefer untreated scallops, while others may not mind the use of STPP if it results in a better product.

To get a more accurate picture of the prevalence of STPP-treated scallops, you may want to:

• Consult with Seafood Retailers: Ask your local fishmonger or grocery store about their sourcing practices and whether they offer untreated scallops.
• Check Product Labels: Look for information on the product label, especially if you're purchasing pre-packaged scallops.
• Research Seafood Industry Reports: Industry reports and studies may provide insights into the use of additives like STPP in the seafood industry.

How to identify a treated scallop

Have you ever fallen victim to buying a questionable scallops from your local grocery store or even fish market? When you choose to buy from Intershell, you are guaranteed to be buying an all natural, dry and untreated scallop - that is our promise.

HOWEVER, if you do end up buying local near you, here are ways to identify whether or not the scallop you have purchase has been processed.

Visual Inspection:

If you have a sharp eye or are a regular scallop consumer, you may be able to identify a processed scallop before even cooking it. However, scallop processors can be really skilled and incognito about processing scallops: They only treat the scallop with a little bit of STPP and only let it sit overnight (we call them “overnighters”). In this case, it may be harder to tell just by looking at it in its raw state.

• Color: Treated scallops often appear ivory white. Natural scallops have a more natural, slightly off-white, beige or even pinkish hue (plus the occasional pumpkin/orange scallops you may get in your batch).
• Texture: Treated scallops can feel more spongy, slippery, or rubbery due to the added moisture. They also appear very smooth, with no detail or separation with the mussel. With natural scallops, you can clearly see the fine lines & details of the scallop mussel. have a firmer, more delicate texture.  
• Packaging: Be warned the packaging is not always accurate. The FDA regulations claim that as long as the scallops isn’t treated with more than 80% solution, by law, scallop processors do not have to disclose that the scallop is processed. You can check the label for any indication of additives or treatments, such as "sodium tripolyphosphate" or "STPP” but it is not a guarantee that it doesn’t contain even the smallest amount of STPP.

Cooking Behavior

Cooking the scallop is where you can really tell. the difference.

• Texture Change: It is very difficult to get a nice pan sear on a processed scallop due to the extra water and liquid they hold. They will also shrink in size a significant amount.

• Water Release: Treated scallops tend to release more water and the liquid of the solution during cooking, which can lead to a less flavorful and less crispy result.  

Sensory Evaluation:

• Taste: Natural scallops have a sweeter, more delicate flavor and you can eat as sashimi. Treated scallops may have a slightly bland or even chemical taste (yuck).
• Smell: Fresh, natural scallops should have a mild, ocean-fresh scent. Treated scallops may have a less distinct or even slightly off-putting odor.

Additional Tips:

• Buy from reputable sources: Intershell Seafood  Choose reputable seafood suppliers or fishmongers who prioritize quality and transparency.
• Ask questions: Don't hesitate to ask your fishmonger about the source and processing of the scallops.
• Consider purchasing shell-on scallops: This can be a good way to ensure that you're getting a natural product, as it's more difficult to treat scallops with STPP when they're still in the shell.

By paying attention to these factors, you can make informed choices and enjoy the superior taste and texture of natural scallops. It's important to note that while STPP is generally considered safe for consumption, some individuals may have sensitivities or dietary restrictions that would make them prefer untreated scallops.
