@JiK Well, I would, but I'm still thinking about it. The intrinsic power output is that given by the Stefan-Boltzmann law. The environment simply affects in what way this energy was supplied to the Lion (either absorbed through its skin or eaten). To me it makes no sense (even for a crazy question) to subtract the power input from an external source (absorbed heat/radiation) in the same way that I do not subtract the power due to the rate at which the Lion is eating antelope. They both supply energy to the Lion, which it then radiates away at the approximate rate I've calculated. I'll edit.

No, I was just rounding up 18% from Table 3. I suppose if I was writing the paper I would argue this demonstrates that it is not especially heat sensitive. I also see from the graph that there is very little difference (none at 22C) between the Heat and PEF curves until you get beyond 40 days storage. So whilst the storage temperature seems important, the processing bit seems much less so.

Thanks for this. The comment at the end is a bit puzzling. Table 3 appears to show that even pasteurisation at temperatures higher than normal (95 vs 72) does not decrease the vitamin C content by more than 20%. I am going to follow this up on Chemistry SE and see if I can find out what is going on.

@David I am well aware of that. I placed the lions and the Sun in a similar environment.
