Thinking out loud, it depends on where it’s grown, not eaten.
There may be minhag hamakom in Eretz Yisroel not to rely on the lenient opinions relied upon in America and Europe, but that’s a different matter.
As far as powdered milk, many poskim discussed it. Famously, Rav Tzvi Pesach Frank was mattir, and interestingly, he was actually referring to milk powder which came from the US.
The Chazon Ish argues on the powdered milk Kula (although was mattir based on the sevara of the Pri Chodosh). I’ve seen a couple of sources that the Chazon Ish was only mattir under very difficult circumstances.
