The prototype was great, but when the production-run lot arrived, both the texture and the palatability were something else entirely. On the ground in pet food OEM, this is not a rare story. Not a single thing in the recipe (formulation) was changed. The production method, too, was confirmed to be the same extrusion. And yet, even so, the finished product can turn out different.<\/p>\n\n\n\n
This article organizes the reasons through the lens of equipment differences between factories (differences in actual production equipment and operating conditions). And now that AI has made it easy to connect with factories directly, why does a third party still matter \u2014 one who assesses whether your own recipe can be reproduced at a given factory, and who specifies the process steps? We explain this from both the technical and the decision-making side.<\/p>\n\n\n\n
\nBeing able to connect with a factory and being able to assess whether your own recipe can be reproduced at that factory are two entirely different things. The former has become easy thanks to AI technology and the like, but the latter remains difficult to assess.<\/p>\n<\/blockquote>\n\n\n\n
What you will learn from this article<\/h4>\n\n\n\n
\n
- Why the finished product can change with a factory’s equipment differences, even with the same recipe and the same production method (seven examples of equipment differences)<\/li>\n\n\n\n
- The dividing line between what a factory’s can-do assurances and certifications (GMP, HACCP, etc.) guarantee and what they do not<\/li>\n\n\n\n
- The risk that, when you get the assessment wrong, problems surface only after the contract, with a delay, across three fronts: quality, supply, and concept reproduction<\/li>\n\n\n\n
- What the areas of judgment are that the buyer should specify, rather than leaving the process up to the factory<\/li>\n\n\n\n
- How a multi-factory network and expert judgment work to protect a recipe’s reproducibility<\/li>\n<\/ul>\n\n\n\n
Note that this article makes no definitive claims about efficacy or outcomes.<\/p>\n\n\n\n
Reaching a factory is one thing; judging it is another<\/h2>\n\n\n\n
In recent years, advances in generative AI and search have made it astonishingly easy just to find overseas factories and get in touch with them. Type in Thailand pet food OEM factory and a list of candidates is at your fingertips in seconds.<\/p>\n\n\n\n
This raises a question. If you can connect with factories directly, surely the trading company in the middle is no longer needed?<\/strong><\/p>\n\n\n\n
What a yes, we can do it does not guarantee<\/h4>\n\n\n\n
If you ask a factory, can you formulate this functional ingredient, or can you make kibble with this texture, most factories will answer yes. That answer is not a lie. They have the equipment, and they have a track record of making similar products in the past.<\/p>\n\n\n\n
But what that yes answers is the question of whether they have the capability to make products in that category<\/strong>. To the question of whether the concept your recipe intends can be reproduced on that factory’s production equipment<\/strong>, a yes gives no answer at all.<\/p>\n\n\n\n
The same can be said of certifications.<\/p>\n\n\n\n
\n
- GMP (Good Manufacturing Practice)<\/strong> indicates that systems for production procedures, records, and traceability are in place.<\/li>\n\n\n\n
- HACCP<\/strong> indicates that there is a system for analyzing hazards (foreign matter, microorganisms, etc.) and monitoring critical control points.<\/li>\n<\/ul>\n\n\n\n
Both are proof that a product is made safely and under a certain quality-control system. In the United States as well, for animal food, 21 CFR Part 507 sets out a framework covering cGMP (current Good Manufacturing Practice), hazard analysis, risk-based preventive controls, record-keeping, and so on, and it is important for verifying safety, hygiene, and control systems. On the other hand, whether your recipe’s specific temperature profile and coating conditions can be reproduced<\/strong> falls outside the scope of such certifications and systems, and is an area that must be verified separately (Note 1).<\/p>\n\n\n\n
Mind the scope of regulations and certifications<\/div>\nGMP, HACCP, and the Pet Food Safety Act are frameworks that safeguard safety and quality-control systems; they do not guarantee the reproduction accuracy of a specific recipe itself. Having the certifications in place is a precondition, but please note that it is not a sufficient condition for reproducing the concept.<\/p>\n<\/div><\/div>\n\n\n\n
Reaching a factory has become easy. But assessment has not. From the next section, we look concretely at what that assessment actually involves.<\/p>\n\n\n\n
A factory’s equipment differences change the finished product<\/h2>\n\n\n\n
The recipe is the blueprint; the production equipment is the actual machines and operation at the factory. Even with the same blueprint, if the machines and operation differ, the product that comes out can change.<\/p>\n\n\n\n
Why results can vary even with the same production method<\/h4>\n\n\n\n
What is written in the recipe or spec sheet is the design values. Instructions such as heat by extrusion or coat the surface with fat fall into this category.<\/p>\n\n\n\n
But in the actual factory, these design values are realized under each factory’s own equipment and operating conditions<\/strong>. How the barrel (the extruder tube) temperature is ramped up, the residence time ingredients spend inside the machine, the shape of the blades, the airflow in the drying oven \u2014 these production-equipment-side conditions differ from factory to factory.<\/p>\n\n\n\n
This distance between the design values and the production equipment is the root cause of the finished product changing even with the same production method. First we present seven representative equipment differences in a list, then organize each in detail across four points: assessment point | equipment difference | impact on the concept | why it stays invisible through certifications or a yes.<\/p>\n\n\n\n
