Dose Uniformity in Infused Beverages
Nanoemulsions exist in large part to solve a basic incompatibility. Oil (in this case, cannabinoid oil) and water do not mix, and a well-engineered emulsion disperses the oil into droplets small enough to remain evenly distributed in a beverage throughout its shelf life. That even distribution is what makes consistent dosing possible.
Emulsion performance can still be compromised, and those failures trace back to how the emulsion was engineered, and its compatibility with the beverage environment and manufacturing process.
Inside the can
Low pH, high sugar, high shear, and sustained heat are all forces that work against emulsion performance. As the protective shell around the oil droplet wears down or fails, the particles clump together and rise to the top of the can. The result is a foul-tasting product with uneven dosing.
The strongest emulsion formulations account for and protect against the full suite of potential threats, ensuring broad compatibility from seltzers to sodas.
Across a production run
Each can across a batch must match its label's potency claim. Improper mixing and processing can jeopardize consistency throughout a production run. Variance is a reality, common in manufacturing of all types; it is important to identify the right partners and processes to minimize the variance windows. Working with an experienced hemp beverage manufacturer will save your product from unnecessary complications from mixing to filling.
What to require
Inside the can. Emulsion stability data and compatibility data for your specific formulation. Stability testing answers whether the emulsion holds over time. Compatibility testing answers whether it holds in your beverage, at your pH and sugar level.
Across a run. A proven processor, and BME testing (beginning, middle, end) before the first run with any new manufacturer, any new SKU, or any other change to the process. Three cans pulled from each third of the run and tested separately show whether potency held as the tank drained. Blending them into one composite sample averages the three points and reports a number that looks correct whether or not the run was even.
Where we sit
We control the emulsion: how well it resists separation, and how closely one of our lots matches the next. Both are measurable, and we test against the conditions a real beverage puts an emulsion through.
Unfortunately, we do not control mixing protocol, fill accuracy, line speed, thermal exposure during processing, or what happens to a pallet in a warehouse. Those decisions belong to the manufacturer and the supply chain. Fortunately, we have accounted for many of the possible avenues for failure and built a resilient emulsion and partner network to support our customers.

FAQ
Can hemp beverages be dosed consistently?
Yes. A well-engineered nanoemulsion stays evenly dispersed through a normal shelf life, and production variance is managed through partner selection and the execution of best practices such as in-run sampling. Inconsistency points to an emulsion mismatched to its formulation or a scale nobody managed, not to a limit of the category.
Why do two cans of the same THC beverage sometimes feel different?
Common causes include an emulsion separating inside the can because it was not built for that formulation, and mixing or fill variation during a production run. Both have established controls.
What should I ask an emulsion supplier for?
Stability data over your intended shelf life, compatibility data for your specific formulation, and uniformity results across multiple production lots.
