Does honey actually tenderize meat? I was recently reading a cooking manga named Shokugeki no Soma, in which the protagonist uses unconventional methods to cook specific dishes. In one chapter, he uses honey specifically to tenderize meat in a short amount of time.  Here's the chapter page specifically:



I tried it for myself but can't seem to replicate the same thing he's done, if anything the beef remained relatively hard, and not soft as the manga describes. While some scenes are somewhat outlandish there is a certain truth to most of the cooking terms thrown around in the manga, so I'm curious: does honey actually contain proteases that tenderize meat quickly? 

This article on LIVESTRONG.com seems to support the other fact in the same page which claims that pineapple can be used to tenderize meat, but it doesn't make any reference to honey at all.

If you're curious, this is the anime version of it:

Based on the description given in the manga (specifically "I rubbed it on the meat before boiling" [emphasis mine]) I would guess that this is not actually an effect of tenderization at all.  Instead, the effect is possibly closer to that of velveting.

The velveting technique is typically done with a thin coating of corn starch, and my working theory is that this seals in the natural juices of the meat while preventing the outer layers from drying out. Being thick and viscous, honey might have much the same effect. As a result, the final product seems more tender, but that's just because it's been more delicately cooked - not due to any special tenderizing power of the honey itself.
