Best way to preserve site authority / juice when moving a property to Facebook?

Hi, so, I have a website. Let's call it a cooking website with about 300 pieces of content cross-listed among 20 categories.

I want to move my entire site, hook line and sinker, to Facebook. My first thought was to do this with a domain-wide 301, as that would preserve most of the authority and juice my site has built over the years... but would this have a corollary effect of unfocusing my keyword strategy? E.g. is there a risk in doing a sitewide 301 to a single landing page, in that some of the juice I'd be passing to my new home page would be from, say, "recipes for jelly donuts?"

Has anyone had an experience making a large product transition like this, and are there any current best practices?

Thanks!

I haven't done a move like this, but my first thought is some may question why you want to move a site that you have control over now to someone else's platform and give them control over it.

Totally valid question.

In this case, it's a matter of the content chasing the users and accepting that for the type of content I'm offering, the average user would likely prefer to stay inside of FB. But, as you point out, it's absolutely a non-zero risk, and domain juice is where I'm starting the risk-assessment process :).
