0.17 grams of anhydrous citric acid crystals when added to 1 gallon would be ~50 ppm, or the maximum amount of citric acid that will dissolve in cooking oil. Anything above 0.17 grams added to a gallon of oil will cause citric acid to precipitate out of solution and drop out of the oil.

Someone should check my work. Trust but verify, as they say!!!

On a mg/L basis (milligrams per Liter), which is close to ppm only when the liquid media has the density of water, whereby water is 1 gram per CC, and cooking oil is 0.915 grams per CC, so we will be off by a small amount, it becomes:
29.2 mg/L = 29.2/1000 grams/L = 0.0292 grams of citric acid in 1 liter of cooking oil.
There are 3.7854 Liters in 1 US Gallon.
Therefore 29.2 mg/L = 0.0292 x 3.7854 = 0.11053 grams of citric acid per gallon.
When we apply our density correction factor we then get:
0.11053 grams x 0.915 grams/mL = 0.101 grams of citric acid per gallon = 29.2 ppm
The earlier computation method indicated that 0.104 grams per gallon was required for 30 ppm, so:
29.2/30 x 0.104 = 0.101 grams of citric acid per gallon = 29.2 ppm
Conclusion: Thus by going at this problem via a completely different path (method) we come to the very same answer that for every 1 US Gallon of cooking oil we should add 0.10 grams of anhydrous citric acid whereby to achieve the ideal benefit from the citric acid in purifying the oil.

There are ~4.8 grams of finely granulated anhydrous citric acid in 1 teaspoon.
0.10/4.8 = 0.02083 teaspoons.
1/16/3 = 0.02083
Therefore 1/16 of a Teaspoon of granulated citric acid powder, when added to 3 gallons of cooking oil, would result in ~29.2 ppm, or the ideal amount.
1/16 of a teaspoon is commonly called a "pinch".
So a 'pinch' of citric acid crystals should be added to every 3 gallons (US) of cooking oil.

I have to question 1/16 as a pinch I had to open my fingers much more then 1/16 to pinch the waitress.
Then again the size of things has got much larger since 1930's
if my assessment that waitresses assets have got bigger please meet at Hooters for wings to discuss this matter Happy Hour Starts after 4:00PM

I will experiment with 1/16 of citric acid I have gone approximately 1/4 teaspoon BUT also using more then 3 gallons of Oil in our Pressure Fryer so it may equal out

1/4 teaspoon of citric acid crystals added to 12 gallons of cooking oil would be spot on.

If you read the study, it takes 4 weeks for 50 ppm of citric acid to dissolve into cooking oil. I think that's the main reason why 29.2 ppm is settle upon as the ideal. It's likely that 29.2 ppm dissolves into the oil within a time that is far more reasonable than 4 weeks.

so you need to put citric acid in the oil and let it sit. or find oils with citric acid in it
