...und viele Hundefutterhersteller, gerade im kostengünstigen Segment, nutzen es.
Was verbirgt sich dahinter?
"A protein generally obtained from plant sources (soybeans, corn or wheat), then broken down into amino acids by a chemical process called acid hydrolysis. Hydrolyzed animal protein is sourced from animals. Used as a flavor enhancer in numerous processed foods because of its "umami" (savory meat flavor) taste. It has a high level of sodium and MSG, and is a low-quality protein source. Also see Monosodium Glutamate (MSG)."

...wird übrigens auch in der menschlichen Ernährung verwendet
Hier nch mehr (engische) Info:
Low grade, controversial or vague ingredient we usually recommend avoiding
Vegetable protein extract (or isolate) is another term that doesn't shed any real light on what is in the food. It gives no indication of which vegetables are used, nor does it say how the protein is extracted, although the most common methods involve chemical reactions that are far from what most people would regard as 'natural'.
For dogs, vegetable proteins are nutritionally inferior to those found in meat. Common sources of vegetable protein include soya, maize and wheat which have all been linked to dietary intolerance and, in our opinion, should be avoided with sensitive dogs.
Some nutritionists have also speculated that vegetable protein extracts might also be a pseudonym for MSG (monosodium glutamate), the controversial food additive that some believe to be mildly addictive.
