The journey of a chilled ready meal: eight steps from kitchen to plate

A chilled ready meal changes hands several times before it reaches you: a cook, a kitchen fridge, a van, a machine, then you and a microwave. Every handover is a chance for it to warm up, and the microwave at the end cannot undo a mistake made at the start.

We follow the meal through eight steps using public food safety guidance, mostly from Australian and UK health agencies and the World Health Organization: good practice, not Thai law. At each step we add what Plate Mate confirms about its own meals, and nothing beyond that. If all you need is the difference between chilled and frozen food, start with that comparison.

Why every link of the chain matters

Food poisoning bacteria can grow between 5 °C and 60 °C, the range regulators call the temperature danger zone (FSANZ). A chilled meal spends almost its whole life just below that line. Cold slows bacteria down but does not kill them, so every link of the cold chain has to hold.

1. Cooking. The meal is cooked through.
2. Cooling. It goes from hot to fridge temperature quickly.
3. Packing. It is sealed with a date and instructions.
4. Chilled transport. It travels cold to the point of sale.
5. Refrigerated storage. It waits in a cold cabinet or machine.
6. Purchase. You choose it and check the pack.
7. Reheating. It is heated until hot all the way through.
8. Eating. It is eaten soon, or goes back in the fridge without delay.

In the kitchen: cook, cool, pack

Thorough cooking is one of the WHO's five keys to safer food, alongside keeping clean, separating raw and cooked food, keeping food at safe temperatures and using safe water and raw materials. It is only the starting point. As cooked food cools, it passes back down through the danger zone.

That is why the second step has a clock on it. Food Standards Australia New Zealand sets a two-stage cooling target for businesses (FSANZ):

• from 60 °C to 21 °C in less than two hours;
• then from 21 °C to 5 °C or colder within the next four hours.

Large volumes are hard to cool in time, hence the advice to use smaller portions or shallow containers. The home version is similar: divide big batches into smaller portions and refrigerate food once it has stopped steaming (Better Health Channel).

The pack then does two jobs: it shields the food from hands, surfaces and air, and it tells you what the dish is, how to store and heat it, and when to eat it by. A use-by date is a safety date: the food can be eaten on that day but not after it, and only if it has been stored as the label says (Food Standards Scotland). Sealed trays, vacuum packs and modified atmosphere packs protect food in different ways (what each can and cannot do).

On our side, we don't add preservatives when cooking and don't use ingredients that contain them. Leaving them out is a recipe decision and no substitute for safety control: without preservatives, cold storage and the date on the pack matter at least as much. Our approach to ingredients is on the Real Food page. Every meal has a use-by date on the pack, and packs carry reheating instructions. We don't describe our kitchen's cooling equipment or timings here. If that matters to you or your building, it is a fair question to put to any food operator, us included.

On the road and in the machine

Transport is the classic weak link, because food has to leave one cold place before it reaches the next. FSANZ advises moving cold food in insulated bags or boxes with ice bricks and keeping refrigerated food at 5 °C or colder (FSANZ). In Thai heat there is little margin for delay (where the cold chain breaks in hot weather).

At the point of sale, a chilled meal should stay at 5 °C or colder until someone buys it, and the same FSANZ page treats a thermometer as the tool that confirms food is held at a safe temperature. Rotation matters too: the nearest date goes first, a rule known as "first expired, first out" that works just as well in a home fridge.

Meals in our machines are chilled, not frozen. We restock our machines regularly and monitor the temperature inside them remotely. We don't publish a delivery schedule or a target temperature, so ignore any number you may have seen elsewhere and go by the date and instructions on the pack.

In your hands: buy, heat, eat

Choosing a meal is your chance to inspect it. Check the use-by date, then the pack itself: no tears, no leaks, no broken seal. The current menu is on our website, the assortment varies by machine, and the machines map shows the working ones near you.

Reheat until the food is steaming hot all the way through, not just at the edges. In a microwave that means rotating and stirring where you can and leaving standing time (Better Health Channel). Microwaves heat unevenly, and the centre of a dense dish can stay cooler than the sides (how to reheat evenly).

Our machines have a built-in microwave that heats a meal after purchase; it only works after a purchase. We don't give our own time or power settings: follow the reheating instructions on the pack, and if its symbols or wording are unclear, see how to read reheating instructions.

A reheated meal is best eaten straight away. If you bought it for later, put it in the fridge as soon as you get home and keep the fridge at 5 °C or below. High-risk food that has spent more than 4 hours in the danger zone should be thrown out (Better Health Channel). Eat the meal by the use-by date on the pack, and keep it in the fridge until you do.

Step by step: the guidance and what we confirm

What this guide leaves out, on purpose

It does not say how quickly our kitchen cools food, which packaging technology we use, what temperature our machines run at, how many days a meal keeps or how often each machine is refilled. Those details are not confirmed for publication, and a guess would not help you.

What you can always rely on is the pack: its use-by date and reheating instructions. If something on it looks wrong, don't eat the meal and tell us. You can reach us on WhatsApp, Telegram or by phone; contacts are in the site footer.
