Bisphenols are chemical compounds mainly used in the production of plastics and resins. The most well-known is Bisphenol A (BPA). These substances are commonly found in materials that come into contact with food. Their use improves shelf life, heat and impact resistance, and helps prevent corrosion and contamination from metal ions. Due to their widespread application, bisphenols can enter the body through food and the environment.

Bisphenols like BPA have long been used in packaging coatings and sealing materials to provide durability and stability for example in can linings or lid seals. The issue: BPA acts like a hormone in the body and is suspected of causing long-term health effects. For the confectionery sector, which often involves packaged products with extended shelf lives, this is a major concern.

In 2023, the European Food Safety Authority (EFSA) drastically reduced the tolerable daily intake (TDI) for BPA to just 0.2 nanograms per kilogram of body weight per day. This means even small amounts could exceed the safe limit. Products like chocolate in coated tins or with plastic inner films may pose a risk depending on the type of packaging used.

The European Commission has adopted a new regulation that almost completely bans BPA and related bisphenols in food contact materials. This includes:
• Plastic packaging
• Lid sealants (e.g. twist-off lids)
• Coatings & varnishes (e.g. inside cans)
• Printing inks, adhesives, and silicones

Exceptions for BPA are limited to large containers (>1,000 liters) and specific filters only if no migration into food occurs. Other bisphenols such as BPS, BPF, or BPAF will face the same strict rules if classified as hazardous.

Companies in the confectionery industry need to prepare. If packaging materials containing bisphenols are used or if bisphenols come into contact with the product during production, even indirectly via supply chains restrictions or bans may apply. Key steps include:
• Check for migration: Does the final product contain BPA residues from packaging?
• Evaluate alternatives: Not all BPA substitutes are safe BPS, for example, shows similar risks.
• Talk to suppliers: What materials are being used? Are bisphenol-free options available?
• Be aware of reporting duties: Any future exemption requests will require detailed documentation (not applicable for SMEs).

Bisphenols can also enter products through process water or machinery components. In these cases, they are considered contaminants, similar to heavy metals or dioxins. These entries are assessed based on the EFSA TDI as well.

The upcoming EU regulation introduces clear restrictions: The use of BPA and related substances in food packaging is being severely limited, including for the confectionery industry. One particularly affected area is chocolate production, especially with the upcoming ban on BPA-based moulds. Companies that proactively switch to safe alternatives and collaborate closely with labs and packaging suppliers will ensure product safety and compliance for the future.
