Tests run by Cook's Magazine have shown that without cutting or
injection, there is no marinating method which results in liquid
penetrating more than 1/8 inch or so into meat.

I agree, no appreciable vacuum in a flexible bag, just an absence of
air. Tillia / Foodsaver sells a rigid plastic container specifically for
marinating, which supports this theory. Other vacuum marinating devices
from consumer (Revo) to commercial also make use of a rigid vacuum
chamber and usually a tumbling action as well. I have used quart mason
jars with the Foodsaver jar sealer attachment with decent results,
though it's only good for things like chicken tenders that will fit in a
mason jar.

This is a fact. You need commercial quality equipment to vac bags with
liquid in them.

Some home units can handle a small amount of liquid.

I have used a VacMaster to brine and marinate meats. But that machine is a
best. We used to haul it to barbecue contests but it's a 70 lb boat anchor.

The tray machines create a vacuum in a chamber. The lid is some impressively
thick plexiglass-type stuff, like I imagine you could use for a windshield
in a supersonic jet.

The difference in power between a tray vac and a countertop bag sucker is
considerable. I use both, but if there is very much liquid in what I want to
bag with the bag sucker, I freeze it in a container first, then transfer to
a bag and seal.

Freeze your marinade, chop it up real fast and throw it in the bag with the
food and vac/seal. That's about the best you can do with a countertop
consumer type vacuum machine.

Note that most of these light duty machines use channel bags. The bags used
in commercial machines won't work. The air channels in the bags will take a
certain amount of liquid before it reaches the seal strip, and most of them
have a channel where a small amount of liquid can get past the seal. But too
much liquid, and no seal. Freezing the marinade first fixes that problem.

I can't speak to the penetration factor. (I'll stop there.)

Which is why I like taking a portion of my freshly ground ground beef
and mixing it with yummy stuff and making myself a beef patty with
yummy stuff in it when I buy some new ground beef from Straub's. I'll
bet no bit of beef in ground beef is bigger than about 1/16 inch.

Standard yummy stuff: worchestershire, red wine, chopped mushroom(s if
they are small), dried onions, garlic, paprika, basil...I think that's
all. Oh and a small shot of cheap BBQ sauce, smoky flavor.

Use a dry rub on the meat. That way when you can vacuum seal it. The meats
own juices will mix with the rub and then be sucked back into the meat when
opened.

Why vacuum pack to marinate? I just marinate in a ziplock bag and
if necessary remove any excess air by sucking on a straw. A little
air doesn't matter. I use the bag so that I can get by with less
marinade.

Because it doesn't penetrate that much when you just let it soak. Consumer
vacs don't have much power, but you can help it along by using a jacquard on
the meat before marinating.

Sucking out air with a straw doesn't really do anything. As long as the food
is covered by the marinade, you're good. And really if the marinade is a
little thick it doesn't even have to fully cover if you just turn the food
every so often.

I've got a cannister for my countertop machines (I have two, a full size
Foodsaver, and a compact one about 8" wide) but I've actually never used it.
The machine can only create so much negative pressure no matter what it's
sucking on. But at least it can be sealed with wet stuff inside.

These small machines work great for storing frozen foods, but I do a lot of
prefreezing. Broccoli, for example. When it goes on deep sale I prep and
freeze a bunch of meal sized portions. If you parboil, cool, bag, and then
freeze, it gets mushy. If you parboil, cool, freeze, and then vacbag, the
texture is much better preserved.

Why should using a bag enhance the marination as long as the marinade is in

I agree. I have one of the FoodSaver machines and it does great on meats and vegetables but in the instructions it says not to seal foods that have liquid in the bag. It will just draw that liquid into the channel and you'll not get a seal at all. FoodSaver does make dishes to be used for marinating; I don't have one but a friend said hers did great for meats.

It's a tenderizing tool. I spelled it wrong. It's Jaccard for this item.
http://www.jaccard.com/Meat-Maximizer-Meat-Tenderizer--15-Knife_p_9.html

There are other brands of this type of tool but the name Jaccard has caught
on to describe all of them in the circles where I run.

Using a bag... it's a bag. For a nonpressurized marinade, that is correct,
just have the food in contact with the marinade. Under negative air
pressure, you get some replacing of air in the meat with marinade.

I should have mentioned that I can crush a soda can flat in a VacMaster. Pic

I'm surprised the vacuum makes any significant difference.

Personally, I prefer the marinade to penetrate just a short
distance into the meat. That way one retains both the
additional flavor of the marinade as well as the original
flavor of the meat. It also avoids the marinade changing
the meat texture if it penetrates too far. (One exception
for me is teryaki flank steak which I like marinated
overnight.)

An analogy is cooking a steak on a grill. The browned
(well done) portion on the outside enhances both the flavor
and texture. The rare portion inside retains the original
meat flavor. No-one (at least not those that care for good meat) would want the steak well cooked all the way
through.)

If that's your objective then I agree there's no need for vacuum anything.

Large cuts do benefit more. Look at pork butt... the fatty exterior gets a
great bark and flavor in the smoker. But the interior meat is extremely mild
flavored, bordering on bland without some help. So driving some flavor into
the butt is helpful. However what I do is as much brining as it is
marinating, probably more. Too much acid will just make the meat mushy.
However I've injected, and I've vaccummed, and injection is still the gold
standard for getting briney seasoning mixtures into large cuts.

I suppose if you pounded out paillards of chicken breast and put them in the
vac marinator for a little while it would accelerate getting them fully
seasoned. But otherwise your countertop unit just can't generate enough
negative pressure.

I have no applicable experience in attempting to marinate in a vacuum
bag. However, it seems to me that there are some relevant issues.

[1] If you have a flexible membrane such as a bag, you can get up to
14 or so pounds/square inch of pressure uniformly distributed over the
contents. I use something very much like this to adhere veneers to
substrates and it works better than any clamp system there is.

[2] If you have common liquids, (water solutions, alcohol) and reduce
the pressure sufficiently, the liquid will, effectively, boil and fill
the membrane with water or alcohol vapor thus reducing the pressure
differential.

[3] If you have strong (ridgid) container that can withstand the
pressure differential and no free liquid, I would expect that drawning
a vacuum would, over time, tend to extract liquid from something like
meat or vegetables. The liquid would then boil and reduce the vacuum.

[4] If the vacuum in [3] actually withdrew a significant portion of
the liquid from the meat/veg, and if the vacuum was maintined until
the marinade liquid was present, it might be possible that the
meat/veg would act like a dry sponge and take up the mariade as the
vacuum was released. Seems like a long shot to me, give the equipment
one is likely to have on hand.

*This* is true. Agrees with the research out there. There have not been many research studies of how much effect the pressure has. Some has shown that running the tumbler with vacuum, atmospheric pressure, or excess pressure all produce the same results. It's been shown that the vacuum helps with manufactured meats (where a bunch of small pieces are glued together); it's thought that the vacuum helps remove air that gets into the manufactured meat during the gluing/pressing. But the difference the vacuum makes isn't large.

Tumbler vs no tumbler makes a difference, so the people who buy a tumbler do benefit, but the vacuum is of small benefit, if any.

Injection, OTOH, works, and works well.

But make no mistake, the commercial units are immensely more powerful. The
VacMaster combined with a tenderized (Jaccard) large cut will indeed give
impressive results.

I've never used a tumbler so I can't comment.

Might be good for sucking out air that gets in while jaccarding.

You could do some quantitative tests. Tenderise two similar cuts, weigh, then marinate, one with vacuum and one without. Weigh again. Compare take-up of marinade. Repeat until you have adequate statistics.

Have you tried vacuum cycling? Apply vacuum, back to atmospheric, back to vacuum, back to atmospheric, etc.
