This discussion has been interesting…..
And now, after a bit of research into Sodium Phosphate, I am starting to understand more.
Looking at Dave’s recipe and doing some calcs, I don’t think it’s of any real threat to one’s health, if mixed as per instructed, or at the very least, mixed accordingly to his slow cooked Duck recipe.
I am sure the Mad Hunky suppliers would have researched this, before release but here is my take on it..
Take when I am wet curing Ham for instance, using cure #1 (6% Nitrite)...
The recipe I use, after pumping the Pork and soaking in the wet cure, it allows for a 10% uptake , per net weight of Pork( deduction of bone/skin content allowed for)!!!! So that said, mathematically, I can work out roughly how much Nitrite has been taken on board by weighing before and after the curing process.
Soooo,
To really work out the amount of Sodium Phosphate is in a product brined using Mad Hunky, one would need to weigh it before and after the brining process, then work it out from there.
Remember, the resulting value would be approx., but close enough.
And, until that happens, all that’s been said is guess work
.
So, I am going to make some assumptions………
After a little bit more research, one source I read suggested 6% uptake could be expected when brining Poultry.
Sooooo, making assumptions here that this is correct……………….
Say Dave’s Duck was 2.2 kgs gross weight(about average these days)
Then, you need to realise that not all of this will account as edible. There’s heaps of shit you won’t eat [Bone, Fat(that renders anyway), Neck, Kidneys and skin for some].
So say…. 50% is wasted, inedible,,,
His Duck is now reduced to 1.1kgs net.
That said, his Duck possibly would have taken on approx 66gr of Brine (1100gr x 6%).
Enough of that said….
I have sussed out that his dry packet mixture contains 25% Sodium Phosphate.
In his recipe for the Duck, he mixes 8 tablespoons of dry brine mix with 1000mls of water.
Given that 1 tablespoon equates to 20 grams (approx.), his total brine mixture now should weigh 1160 grams.
So, 160 grams of dry brine mix @ 25% Sodium Phosphate= 40 grams (3.44%)Sodium Phosphate is in his wet brine.
Now, 66gr wet brine uptake x 3.44% = 2.27 grams (2270mg) of Sodium Phosphate that has been absorbed by his Duck…
Were not finished……………
Now, we need to work out the Sodium Phosphate that actually in the meat itself
Now, given all that’s provided on the chart given here
http://www.aussiebbq.info/forum/viewtop ... 19&t=13354
there is no values given for Duck, sooo, I will make another assumption and use the value given for Beef Sirloin (about average) @ 203mg Sodium Phosphate per 84 grams of meat.
This equals .241% Sodium Phosphate
That value applied equates to 2.651grams (2651mg) Sodium Phosphate per 1100 grams of his Duck meat.
Add the sum of the two resulting values (2270mg + 2651mg) = 4921 mg Sodium Phosphate total
Now, no one’s gunna eat a whole Duck….. (I could I guess
)
A 2.2 kg Duck will feed 6, with sides so each would have consumed
820mg Sodium Phosphate.
If my calcs are correct, I would be more than happy to feed this to myself and family.
To Summarise, ya not going to be eating this every day, rather, have it for a weekly or fortnightly Sunday dinner……… and to be honest, I’d be more concerned about cholesterol uptake when eating a Duck…, or the Beers and Wine that go with it
.
Finally, pffft to the health warnings…………
