TL;DR
- ✓Inox 304/316: inert, sheds no particles, doesn't react with food, lasts for decades. Our pick.
- ✗BPA-free plastic: not automatically safe - BPS and BPF have similar hormone effects and aren't covered by the label.
- ✗Melamine / bamboo with melamine binder: when heated, can release formaldehyde into food.
→ If you want one material that solves it all, it’s inox.
Side-by-side comparison
| Inox 304/316 | BPA-free plastic | Melamine | Bamboo (with binder) | |
|---|---|---|---|---|
| No bisphenols (BPA, BPS, BPF) | ✓ By material nature | ✗ BPS/BPF substitutes have similar effects | ✗ Melamine is a plastic | ✗ Binder is usually melamine |
| No formaldehyde release | ✓ Inert at all temperatures | ~ Depends on plastic type | ✗ Releases when heated | ✗ Binder releases when heated |
| No microplastic into food | ✓ Sheds nothing | ✗ Sheds over time | ✗ Plastic | ~ With binder - sheds |
| Dishwasher-safe (up to 60°C) | ✓ No limits | ~ Accelerates aging | ✗ Accelerates migration | ✗ Binder cracks, surface flakes |
| Lifetime | ✓ Decades | ~ 1-2 years before aging | ~ 1-2 years | ~ 1-2 years |
| Used by HocuNjam? | ✓ Yes - grades 304 and 316 | ✗ No | ✗ No | ✗ No |
1. BPA, BPS, BPF: why “BPA-free” isn’t enough
Bisphenol A (BPA) is a chemical that mimics the hormone oestrogen. The EU banned BPA in baby bottles in 2011 (Regulation 321/2011), and in 2023 EFSA drastically lowered the tolerable daily intake (TDI) for BPA - from 4 µg/kg body weight to 0.2 ng/kg, a roughly 20,000× reduction.
But “BPA-free” doesn't mean “bisphenol-free”. Manufacturers often replaced BPA with BPS (bisphenol S) and BPF (bisphenol F) - structurally similar chemicals with the same hormonal effects. A study in Environmental Health Perspectives (2015) found BPS shows almost identical oestrogenic activity to BPA.
Inox solution:stainless steel has no bisphenols by design. The material isn't plastic - there's no need for BPA or its replacements.
2. Melamine and formaldehyde in cheap plates
Melamine is a thermoset plastic produced by reacting melamine with formaldehyde. In the finished product, formaldehyde is bound in the plastic matrix - but with heat (dishwasher, microwave, hot meals, acidic food) some of it can migrate into the food.
EU Regulation 284/2011 limits the migration of melamine and formaldehyde from tableware, but studies like EFSA Journal 2010 (1577) show that migration rises with temperature and food acidity.
Bamboo footnote: bamboo tableware on the market is almost never pure bamboo. The fibres are bound with melamine or formaldehyde-based glue - often up to 50% of the product. In practice, bamboo tableware is melamine with bamboo as filler.
3. Microplastics and particle shedding from plastic
A 2021 study (Environmental Science & Technology) found that plastic baby bottles release 1–16 million microplastic particles per day under normal washing and meal-prep conditions. While the long-term effect is still being studied, lowering exposure is a reasonable precaution - especially for babies who eat and drink proportionally more than adults.
Inox solution:inox doesn't shed particles into food under normal use. The surface is smooth and chemically inert.
4. What paediatricians recommend
The American Academy of Pediatrics (AAP) recommends avoiding plastic for kids' food whenever possible, especially when in contact with hot food. Australian Food Standards and the WHO/FAO expert panel have taken a similar position.
5. Stainless steel grades: 304 vs 316
Not all stainless steel is the same. Grades 304 and 316 are the two food-grade standards recommended for tableware in food contact.
- 304:the standard food-grade steel, corrosion-resistant, used in professional kitchens worldwide. Plenty for kids' plates, cups, bowls.
- 316: adds molybdenum, giving higher resistance to chlorides and acidic food. Preferred for cutlery (spoons, forks) because they touch acidic fruit and juice more often.
- HocuNjam: we use 304 for plates/bowls/cups, 316 for cutlery.
Heads up: cheap imitations often use non-standard grades that can corrode and shed metal into food. The grade should always be clearly stated on the declaration.
