タイトルまたは説明

With soy protein isolate containing as much as 90 percent crude protein, one might be excused to think that, given that the economics are right, a more concentrate source can be used as effectively as soy protein concentrate. This arises from the misconception that the two protein sources are derived from the same process, one being more concentrated than the other — the difference being undesirable compounds. However, this is far from the truth.

In fact, the two soy protein sources are manufactured using quite distinct processes. The differences also extend to the main use these products are intended for: soy protein isolate is a prime protein source for human nutrition products, whereas soy protein concentrate is manufactured for use in animal feeds. The abundance of soy protein isolate, mostly of Asian origin, has prompted many manufacturers to consider this ingredient (often sold at a discount due to quality problems, which do not affect animals) for use in specialty feeds such as milk replacers, piglet feeds and broiler super pre-starters.
