📋 Quick facts

Quick Facts:

• Category: other
• Also Known As: Med fluorid, Lisätty fluoria

Proven Benefits At A Glance:

• Fluoride-modified alumina is a food-contact material additive that doesn’t migrate into food under normal conditions
• The particles remain embedded in plastic and don’t transfer to food through abrasion
• Safety is confirmed for use up to 25% in plastics contacting all food types, with some temperature limits for certain plastics
• Migration of ionic fluoride can occur from swollen plastics under prolonged heat exposure

🔬 The Science

Fluoride-modified alumina is a surface-treated form of titanium dioxide designed for use in food-contact plastics. Here’s what the research shows: #1: The additive particles themselves don’t migrate into food under typical conditions—they stay embedded in the plastic material even when the plastic swells, and they resist being worn away by abrasion (EFSA J, 2019). This means direct particle exposure through food isn’t a concern. #2: The main safety consideration involves ionic fluoride and aluminium that can dissolve and leach from the surface of the particles, particularly when plastics swell in contact with acidic foods (EFSA J, 2019). #3: For most applications, the additive is considered safe at concentrations up to 25% by weight in plastics that contact all food types under any time and temperature conditions (EFSA J, 2019).

However, #4: When the plastic is a polar polymer (a type that absorbs moisture easily, like polyamide) and contacts acidic foods simulated by 3% acetic acid, there are stricter limits: contact should not exceed 4 hours at 100°C to prevent fluoride and aluminium migration from exceeding established safety limits (EFSA J, 2019). The research emphasizes that regulatory maximum migration limits for both aluminium (1 mg/kg food) and fluoride (0.15 mg/kg food) must not be exceeded regardless of application.
