Hosted Canning Dissolved Oxygen
Hosted Canning Dissolved Oxygen: Wild Goose This starts with a pre-purging of the can with CO2. Cask: A DO measurement only reveals what is in the liquid; Most oxygen pickup from packaging will live in the headspace. WaterTech/3M: warranties if DO levels are above 1,200 ppb; bright tank was within specifications at 200 to 500 ppb.

Frequently Asked Questions
What is Hosted Canning Dissolved Oxygen?
Hosted Canning Dissolved Oxygen is package DO control on hosted or owned canning lines. Wild Goose: Dissolved oxygen (DO) is the amount of oxygen integrated into a product during the canning process; This starts with a pre-purging of the can with CO2. Cask: A DO measurement only reveals what is in the liquid; Most oxygen pickup from packaging will live in the headspace. WaterTech/3M: Most manufacturers of cans void their warranties if DO levels are above 1,200 ppb in a canned product; bright tank was within specifications at 200 to 500 ppb.
How does Wild Goose describe CO2 pre-purge and DO control on a canning line?
Wild Goose says: This starts with a pre-purging of the can with CO2; CO2 is heavier than air and this step purges the can of virtually all oxygen; where it receives a laminar blanket of CO2 while simultaneously leveling foam or breaking large oxygen-rich bubbles; Then the can is topped with an end immediately after filling to avert oxygen intake; engineered to minimize dissolved oxygen pickup. Also: Know the DO number in your brite tank; cold liquids can hold more dissolved oxygen than warm liquids.
What Cask myths separate DO from TPO and headspace oxygen?
Cask Debunking 5 Myths About Dissolved Oxygen: Myth 1 Dissolved Oxygen (DO) is the same thing as Total Packed Oxygen (TPO) — Not true; A DO measurement only reveals what is in the liquid and paints a partial picture; Shaken samples provide an accurate picture of TPO. Myth 2: Most oxygen pickup from packaging will live in the headspace. Myth 4/5: Protective oxygen-reducing layers begin with the CO2 pre-purge and micro-foam; The collective result is TPO equivalent to or even lower than counter pressure technologies; overfilling is not required with proper capping-on-foam; keep product loss below 1%.
What WaterTech and 3M ppb warranty and bright-tank numbers are listed?
WaterTech (and matching 3M Liqui-Cel PDF): Most manufacturers of cans void their warranties if DO levels are above 1,200 ppb in a canned product; DO concentration in the bright tank was within specifications at 200 to 500 ppb; starting with fully oxygenated liquid (8,000 ppb) … delivered cider with 200 ppb or less at outlet; Vermont Hard Cider has consistently achieved precanned cider with DO near 15 ppb; fermentation (~50 ppb) with additional pickup during aging and filtration (500 ppb). 3M lists: 1,200 ppb; 200-500 ppb; <200 ppb at outlet; 15 ppb.
What Hach filler-vs-seamer and imagearchive packaging thresholds are listed?
Hach: less than 10 ppb going into the filler; filler pickup about 40 to 50 ppb; shaken dO2 ranged from 300 to 600 ppb; the oxygen had to be coming from air trapped in the foam; Filler pickup is equal to unshaken dO2 minus the base of the filler dO2. Imagearchive packaging-only: Beer should be presented to the packaging lines with less than 50 ppb dissolved oxygen; beers with less than 100 ppb total in package oxygen; achieving less than 500 ppb total in package oxygen.
