Improve nutrient balance, texture, palatability, shelf life or processing — or replace ingredients — while keeping the product your customers already buy.
Products on shelf have to change: an ingredient becomes unavailable, a claim is updated, shelf life falls short or a line runs poorly. Every change risks shifting nutrient levels, palatability and stability, so reformulation needs the same rigour as a new formula.
We reformulate against your current product’s verified profile, change only what the brief requires, and confirm the result by analysis, palatability testing and, where needed, shelf-life studies before the change reaches production.
Start your project with Guires PNLEvery formula is balanced on energy, checked against minimums and maximums for your market and verified by laboratory analysis.
Improve nutrient balance, texture, palatability or processing performance.
Replace unavailable, costly or unwanted ingredients without moving outside targets.
Simplify the ingredient list while keeping nutrition, safety and stability.
Fix oxidation, moisture migration or texture change over shelf life.
Improve acceptance using palatant systems, texture and aroma, confirmed with partner panels.
Make recipes run reliably on extrusion, retort, baking or drying lines.
Changes are measured against the current product so performance does not drift.
Pulse-rich and grain-free changes need taurine and sulphur amino-acid checks.
Ingredient and supplier changes can introduce undeclared species in single-protein diets.
New fats, actives or packs change oxidation and shelf life.
Current product analysed and profiled.
What must change and what must not.
Options calculated and costed.
Bench samples against the original.
Analysis, palatability and stability checks.
Updated specification and label.
Peer-reviewed findings that shape how we design and interpret this work.
Cats need dietary taurine, and taurine status matters in dogs fed pulse-heavy or grain-free diets.
We check taurine and sulphur amino acids in every cat formula and in pulse-rich dog formulas.
DNA studies keep finding undeclared species — 23 of 40 novel-protein and hydrolysed diets in one study.
For single-protein and novel-protein products we specify single-source raw materials, require supplier declarations and design out cross-contact in the recipe and process.
Vitamins A, D, E, K, C and folic acid are the least stable in extrusion; one study lost about 26% of vitamin A at preconditioning and about 34% after extrusion and drying.
Vitamin overages are set from published retention data for your process and confirmed by analysing the finished product.
Each application has its own page with the evidence, the actives and the claim boundaries we work within.
Firm stools, comfortable digestion and a balanced gut microbiome.
A healthy skin barrier and a glossy coat, driven by the right balance of omega-6 and omega-3 fatty acids, protein quality and key micronutrients.
Lighter, more satisfying diets that help pets reach and keep a healthy weight.
Chews, kibbles and treats that help keep teeth clean and breath fresh.
Every ingredient we choose for reformulation & optimisation is assessed for nutrient contribution, digestibility, processing behaviour, palatability and the rules in your market — and sourced to your specification.
Regulation updates, the latest research, recalls and market trends that shape reformulation & optimisation — written by our formulation, testing and regulatory teams.
We compare prototypes against the current product and can confirm acceptance with partner palatability panels.
Sometimes; we review the label and claims for your market after every reformulation.
Yes. Reformulations are designed for your manufacturer’s equipment and ingredient list.

“Meeting AAFCO nutrient profiles while staying clean-label and within budget had defeated our in-house team. Their formulation achieved all three.”
“With no in-house nutritionist, we needed a hypoallergenic formula built from scratch. They delivered the full recipe, explained the reasoning behind every ingredient and supplied a specification our manufacturer used directly.”
“Our functional treat line needed targeted joint-health ingredients that stayed stable through manufacturing. The recipe they developed met both requirements and came with thorough nutritional records.”
Real client projects — the problem, the science and the result.
An established Indian pet food brand asked Guires PNL to convert its top-selling adult dry dog food to a clean-label recipe — no artificial preservatives, colours or flavours — with equal palatability, an acceptable shelf life and an unchanged shelf price.
Read the case study →A premium Indian pet food brand’s chicken-and-vegetable wet diet failed three production trials in a row after sterilisation. Guires PNL traced the cause to the formulation, not the retort, and validated a fix the manufacturer could run on its existing line.

Every Guires PNL product is formulated to comply with the FEDIAF Nutritional Guidelines and the AAFCO Dog and Cat Food Nutrient Profiles. Neither body issues certificates to manufacturers, so compliance is verified independently against their published standards — and every product comes with a complete documentation package for regulatory submissions in the EU, US, Australia and Asian markets.
