Why Two "Same" Products Have Different Ingredients

Same front-of-pack design, same brand name, same product name. But when the second pack turned up and I lined the two nutrition panels up side by side, the numbers weren't even close. One version had 966 kJ per 100g. The other had 1445 kJ — roughly 50% more energy for what was supposedly the same snack. Sodium went from 1246mg to 1410mg. That's when I started wondering if the nutrition table on the back of these packs is just there for decoration.

It isn't, as it turns out. But it also isn't telling the story most of us assume it is.

Same Brand, Same Product Name, Different Factory

Once I actually read the small print on both packs, the answer was sitting right there. Each pack lists two different addresses: a "commissioning party" (the brand that owns the recipe) and a separate "commissioned manufacturer" — a different factory, often in a different city, actually making the product under licence.

This is standard practice, not a red flag on its own. Big brands frequently outsource production to several regional factories to meet demand, especially for something as simple as candied fruit. The problem is that "same brand" doesn't automatically mean "same production line, same suppliers, same exact recipe." Two factories working from the same product standard can still land on slightly different formulations, and that shows up in the numbers on the back, not the front.

The nutrition label is required precisely because the marketing on the front of the pack can't be trusted to tell you what's actually inside. In most countries, food regulators require that panel to reflect the real, tested composition of that specific batch — which is exactly why the "same" snack from two different production runs can come out with genuinely different calorie and sodium counts. It's a good habit to check the manufacturer's address alongside the brand name, not just the logo, especially for snack foods and dried fruit that get made across multiple regional factories.

Same Shelf, Different Channel: Why Delivery Versions Get More Additives

A friend's version of this story: she bought a small cake in-store, loved it, then reordered what looked like the identical product through an online grocery app. The in-store version's ingredient list led with egg, wheat flour, sugar, trehalose, vegetable oil, milk powder and butter — fairly close to what you'd bake at home. The delivery version added several preservatives that weren't in the fresh-bought pack.

This one has a fairly boring explanation: shelf life. A cake bought fresh and eaten within a day or two doesn't need much help staying safe. A cake that has to survive a warehouse, a delivery van and a few days sitting in a locker does. Preservatives aren't automatically dangerous — most of the ones used in packaged food have been reviewed extensively by food safety agencies — but "extra preservatives for a longer supply chain" is a genuinely different product from "made fresh this morning," even when the label uses the same product name.

Same Word on the Label, Very Different Ingredient Panel

This next one still catches people out, including me. Three bottles from the same soda brand, all labelled "soda water" of some kind. The plain, zero-sugar version had exactly three ingredients: water, carbon dioxide, sodium bicarbonate. A flavoured, limited-edition version from the same brand listed ten, including two different types of sugar, a preservative, an artificial sweetener and a colouring agent — with more than six times the energy per bottle.

Nothing sneaky happened here. It's just a completely different drink wearing a similar label. The reason this is worth flagging is that food labelling rules in most markets, including the US and Australia, require ingredients to be listed in descending order by weight — the ingredient making up the largest share of the product goes first, down to the smallest. Once you know that rule, an ingredient list stops being a wall of text and starts being genuinely readable: whatever's in positions one and two is what you're mostly eating, no matter what the front of the pack implies.

Same Product, Different Country: What Changes Across Borders

The last version of this is the one people ask me about most: does Coke really taste different depending on where you buy it? I noticed it travelling — a can bought in the UK tasted less syrupy and fizzier than the one I'm used to at home, and a case brought in from Hong Kong tasted the same as the UK version.

Checking the labels backed that up. UK and Hong Kong versions list plain sugar with no high-fructose corn syrup, which lines up with how the drink is generally made outside North America — most countries use cane or beet sugar, while the US has leaned on corn syrup since the 1980s for cost reasons tied to corn subsidies. Worth noting this isn't a simple "everywhere else does it better" story — sweetener choice varies by country for a mix of cost, regulation and local taste, not a single universal formula. I'm not claiming one is healthier across the board, since researchers are still divided on whether sugar and high-fructose corn syrup behave meaningfully differently in the body — just that they're genuinely not identical drinks, and the label is the only place that tells you so.

What Sulfites and Sweetener Names Are Actually Doing There

A couple of the additives on that peach strip pack are worth knowing by name rather than just skimming past. Sodium metabisulfite (the "SO2" family of preservatives) is used to stop dried fruit browning and keep it shelf-stable. It's approved and widely used, but a small share of people — particularly those with asthma — can react to it with wheezing or skin symptoms, which is why it has to be declared rather than folded into a vague "preservative" line. Cyclamate and sodium saccharin, the two sweeteners further down that same list, are older artificial sweeteners that are cheaper than sugar, which is part of why cheaper "candied fruit" style snacks lean on them instead.

None of this means additives are something to panic about. It just means the ingredient list is doing real work, and it's worth thirty seconds of your time before the box goes in the trolley.

The Actual Habit Worth Building

The pattern across all four of these is the same: the front of the pack sells you an idea, and the back of the pack tells you what you're actually getting. Brand name, product name and packaging photo are marketing. Manufacturer address, ingredient order and the per-100g numbers are the parts that are legally required to be accurate.

I'll be honest, standing in an aisle cross-referencing sodium figures between two nearly identical boxes isn't anyone's idea of a fun grocery trip. That's the exact gap we built the label scanner in PickFresh to close — point your phone at the panel and it pulls out the numbers that actually matter, so you're comparing them instead of guessing from the front of the box. If this kind of thing interests you, it's worth browsing the rest of the blog too — there's more where this came from.

Next time two "identical" products feel a little off, flip them both over before you decide. Nine times out of ten, the label already told you why.
