Lobster Broth

Seafood processors cook lobsters for meat and produce cooking water containing dissolved protein, minerals and flavor compounds. Straining that liquid makes broth; concentrating its solids also gives processors a usable flavor ingredient.^1,6

1. 01 // Source Lobster and water Cooking lobster for meat leaves liquid that has taken up compounds from the animal.
2. 02 // Process Cooked Heat moves soluble protein, minerals and flavor compounds into the surrounding water.
3. 03 // Process Solids removed The cooked lobster is separated from the liquid; processors may concentrate the remaining broth.
4. 04 // Output Lobster broth The liquid supplies moisture and seafood flavor when added to a wet food recipe.

1. 01

   Adds seafood flavor

   Cooking transfers lobster flavor compounds into water. Broth lets a manufacturer give a recipe a seafood note without making lobster meat a main ingredient.^1,2

2. 02

   Supplies recipe moisture

   Wet food needs liquid for mixing and processing. Broth fills that role while adding flavor, though the label does not state how much lobster material it supplies.^3,5

3. 03

   Uses a processing stream

   Lobster cooking water is a seafood processing leftover. Concentrating its dissolved solids gives processors a usable flavor ingredient from liquid they would otherwise discard.¹

How much A food science study made broths with 0.5% and 1% lobster concentrate; it did not report an addition rate for dog food.¹

1. Brands say

   Adds moisture to wet food

   Evidence

   1. Strong
   2. Some
   3. Thin
   4. None

   A food science study prepared liquid broths with 0.5% and 1% lobster concentrate. Adding liquid broth adds water to a recipe. That benefit does not make it more hydrating than the same amount of water.¹

2. Brands say

   Makes picky dogs eat more

   Outruns the evidence

   Evidence

   1. Strong
   2. Some
   3. Thin
   4. None

   A panel of 43 people evaluated lobster-flavored broth for seafood applications. That measures human responses to flavor, not whether dogs prefer the food or eat more of it. The cited research did not test dogs.²

3. Brands say

   Provides meaningful lobster protein

   Outruns the evidence

   Evidence

   1. Strong
   2. Some
   3. Thin
   4. None

   One concentrated cooking-water extract was 30% protein on a dry basis. The study did not measure how much protein a dog receives from a food containing liquid broth, so a broth listing proves no meaningful protein contribution.^1,3

4. Brands say

   Supports joint and gut health

   Outruns the evidence

   Evidence

   1. Strong
   2. Some
   3. Thin
   4. None

   An industry article raises these possible broth benefits and says they need study. The lobster cooking-water study measured composition and prepared 2 broth strengths; neither source reports joint or gut outcomes in dogs.^1,6

5. Critics say

   Lobster broth is just filler

   Outruns the evidence

   Evidence

   1. Strong
   2. Some
   3. Thin
   4. None

   Broth supplies liquid and flavor, both jobs in wet food. A concentrated lobster cooking-water extract contained flavor compounds, protein and minerals, but those findings do not make liquid broth a major nutrient source.^1,5
