Commercially representative pilot batches with validated processes and a full technology-transfer package — so you know your product can be made, safely, before you commit to scale.
A recipe that works on the bench does not always work on a production line. Pilot manufacturing makes the product at a commercially representative scale, so processing behaviour, texture, shelf life and cost can be checked before a brand commits to full production runs.
Our pilot work runs through Guires Manufacturing and GMP-certified partner facilities for wet, treat and supplement formats. Each pilot ends with a technology-transfer package — process parameters, specifications and batch records — so your chosen manufacturer can reproduce the product consistently.

Durations depend on format and scope, and are set out in your proposal.
Process and facility requirements for each market. Last reviewed: September 2026.
| Market | Process requirement | Facility and validation |
|---|---|---|
| United States | Canned pet food must follow FDA low-acid canned food regulations (21 CFR 113) | Process preventive controls validated by or under a PCQI (21 CFR 507.47); facilities must register with FDA unless exempt |
| European Union | Canned pet food: minimum Fc value of 3. Other processed pet food: at least 90 °C throughout unless an authorised alternative applies; dog chews need a treatment that destroys pathogens including Salmonella (Reg. (EU) 142/2011, Annex XIII) | Pet food plants using animal by-products must be approved |
| United Kingdom | Same heat-treatment standards as the EU (assimilated law) | APHA approval for sites making pet food from animal by-products |
| India | Manufacturing to IS 11968:2019 (BIS) | Imports with animal-origin material need a veterinary health certificate (DAHD S.O. 3926(E)) |
| Australia | AS 5812:2023 manufacturing and marketing practice (voluntary) | PFIAA members audited by third parties against AS 5812 |
Peer-reviewed studies show what processing does to nutrients and pathogens — and why pilot data matters.
Retorting cut thiamin in canned cat food by 30.4%, whatever the container; time to reach target lethality ranged from 29.5 to 45.6 minutes by pack size.
Vitamins are measured after processing, and heat penetration is studied for each pack format.
In moist canned cat foods, on average 48.6% of lysine had undergone early Maillard reaction.
Processing losses are allowed for in the formula and checked on pilot product.
Salmonella stayed detectable on dry pet food for 19 months; E. faecium is a conservative surrogate for validating heat steps.
Kill steps are validated with surrogates where needed, and post-process hygiene is part of the transfer package.
13 of 84 dried-meat dog treats bought in the UK carried Salmonella; air- and freeze-dried treats had no cooking step.
Dried and freeze-dried treats get a separate, validated pathogen control.
HPP at 586 MPa achieved 5-log reductions of Salmonella and STEC in raw pet food, but Listeria was more resistant and results depended on the formula.
Each HPP recipe is validated individually.
Of 3,691 US pet food recalls from 2003 to 2022, Salmonella caused 23% and chemical causes 32%.
Pilot trials generate the validation data your food safety plan needs before launch.
Pilot batches give you real product for retailer and distributor presentations, investor meetings and export discussions.
Pilot and commercial production run through Guires Manufacturing, so process settings, specifications and documentation carry straight over to scale-up.
Stay ahead with regulation updates, the latest research, ingredient spotlights, recalls and market trends for pilot manufacturing — written by our formulation, testing and regulatory teams.
Every project at Guires Pet Nutrition Lab runs inside an ISO 9001:2015 certified quality system and FSSAI-licensed operations, with documented methods, calibrated instruments, traceable raw materials and reviewed reports — so the results behind your product can be checked and defended.
Not in our pilot plant. We formulate and test extruded products and advise on extrusion trials at a suitable partner facility.
Pilot batch sizes depend on the format and the facility, and are confirmed in your proposal.
Yes, provided they meet the agreed specifications.
We review the data with you, adjust the formula or process, and agree whether to re-run. Any re-run is agreed and quoted with you before it starts.
Ownership of formulations, process data and the transfer package is agreed in the contract, and we are happy to sign a mutual NDA before you share details. Clients own their project data.
Pilot product is intended for testing, sampling and buyer presentations. Selling it depends on the producing facility’s registrations and approvals for your market.
Clients in the USA, UK and UAE on working with Guires PNL. Names are withheld at clients’ request.
“Scaling our dry kibble recipe from lab batches to pilot production was our biggest unknown. Process validation and batch trials proved the product stayed consistent at scale before we approached a co-manufacturer.”
“They helped us define processing conditions and batch specifications for our wet food range ahead of commercial production. The validation data made scale-up planning noticeably faster.”
“Moving our treat line into pilot manufacturing raised questions about equipment, batch sizes and technology transfer. Their team resolved each one, so we entered full production well prepared.”
Real client projects — the problem, the science and the result.
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.
Read the case study →A first-time founder had a gently cooked dog food recipe customers wanted to buy — but the contract manufacturer’s first run failed. Guires PNL took the recipe through nutrient analysis, reformulation, pilot processing, testing, labelling and tech transfer to a first production batch in 90 days.

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.
