The Hidden Science About Your Kitchen Tools

Sept 24, 2025

Food-grade stainless steel is a specially formulated alloy that resists corrosion and chemical leaching, ensuring food safety, hygiene, and long-term durability in food contact applications.

What Is Food Grade Stainless Steel?

The Most Common Food Grade Stainless Steel

Grades like 304 and 316 are widely used in kitchens, commercial food equipment, and utensils. Their high chromium and nickel content enhances corrosion resistance and keeps food safe.

Why Food Grade Stainless Steel Is Non-Toxic

Its smooth, non-porous surface resists absorbing food particles or reacting with ingredients. The chromium oxide layer blocks chemical leaching, ensuring it remains stable and safe for cooking and storage

Where You’re Already Using It, Without Knowing

From water bottles and lunchboxes to ovens, mixers, and fridges, food-grade stainless steel lives in your kitchen without corrosion, stains, or flavour transfer.

What Happens If It’s Not Food Grade?

Using non-food-grade materials can lead to contamination, off-flavours, and health risks. Inferior metals can react with acidic or salty foods, releasing unwanted substances.

How to Tell If Stainless Steel Is Food Safe

Look for grade markings like SS 304 or certifications like FDA, LFGB, or BIS. A magnetic test or corrosion spotting can also help flag poor-quality alternatives.

Built to Last and Safer for the Planet Too

Food-grade stainless steel is 100% recyclable, reusable, and incredibly long-lasting. It is a smart, sustainable choice for homes and commercial kitchens alike.
