Less Heat, More Science
CaniBowl Processing Evidence Protocol
CaniBowl treats processing claims as testable questions. We plan to compare matched samples before cooking, after low-temperature cooking and after retort before making quantitative nutrient-retention claims.
The purpose is to distinguish a plausible mechanism from evidence demonstrated on an actual CaniBowl product.
Sampling design
Measure the full process, not one temperature
Pre-cook
Prepared formulation before thermal processing.
Post-cook
Matched sample after the low-temperature cooking stage and before retort.
Post-retort
Finished product after retort and cooling. Public finished-product claims must ultimately be supported here.
Analytical panel
What CaniBowl plans to measure
Proximate composition
Moisture, crude protein, crude fat, ash and relevant supporting measures, interpreted on both as-fed and dry-matter basis where moisture change can distort comparison.
Heat-sensitive nutrients
Priority candidates include thiamine and selected formulation-relevant vitamins where a qualified laboratory can provide an appropriate validated method.
Protein-quality marker
Total lysine and reactive lysine are preferred research markers when feasible. The reactive-lysine to total-lysine ratio can help identify heat-associated loss of lysine availability, but it is not itself a whole-diet digestibility test.
Process measurements
Batch weights, cooking time-temperature profile, retort programme and time-temperature record, fill weight, pH and other relevant process controls should be captured with each sampled batch.
Claim gate
What evidence unlocks a stronger claim?
Literature hypothesis
External research suggests a mechanism, but CaniBowl has not measured it yet.
Internal analytical observation
A matched CaniBowl batch shows a measured difference across process stages.
Repeated batch evidence
The same direction is reproduced across at least three independent production batches.
Comparative product claim
A comparison against another product or process requires a predefined comparator, harmonised sampling, a statistical plan and appropriate regulatory review.
Current boundary
What “Less Heat, More Science” does and does not claim today
Today, “Less Heat, More Science” describes a process philosophy: control heat exposure, measure the full process and avoid claiming more than the evidence shows.
We can state that processing severity can affect vitamin stability, amino-acid availability and digestibility. We do not currently claim that CaniBowl preserves a fixed percentage more vitamins, retains a fixed percentage more nutrients, causes 5–8% less water loss or is more digestible than conventional pet food.
Evidence basis
Why the protocol is structured this way
Published reviews of wet pet food show that vitamin stability depends on several variables including temperature, time, pH, moisture and formulation. Research on reactive lysine also shows that heat-associated Maillard reactions can reduce lysine availability, while the size of the effect varies with ingredients and processing.
A 2025 controlled-formulation study comparing raw, mildly cooked and retorted dog foods supports treating processing method as a measurable variable, but its digestibility work used rooster assays rather than direct dog trials. CaniBowl therefore treats it as supporting evidence rather than product proof.
