In the context of pet food, how does the functionality of gellan gum blends compare to the standard carrageenan-based system, and what is a specific formulation example?

In gelled pet foods (canned loaves or cold-formed "brawn"), gellan gum blends offer a potent and adaptable alternative to the standard system of k-carrageenan, locust bean gum, and potassium chloride. The key functional comparison is one of efficiency and texture control. As a general rule, low-acyl gellan gum blends can replace k-carrageenan blends at approximately half the total usage level while achieving similar or superior binding and texture. A specific laboratory formulation example demonstrates this: a blend of 0.45% Kelcogel (gellan gum), xanthan gum, and locust bean gum, in combination with potato starch, produced a product similar to one made with a 1.0% blend of carrageenan and locust bean gum. In a prototype canned pet food, 0.75% of a Kelcogel and guar gum blend successfully replaced a system containing 1.3% carrageenan, locust bean gum, and potassium chloride.
