Holland Colours offers PET bottlers and drink brands more options with two new versions of its TasteGuard AA scavenger

With the launch of TasteGuard Liquid and TasteGuard Ultramax, Holland Colours is offering bottled water brands new options depending on their market, sustainability goals, brand positioning, cost base and their suppliers’ production technology. 

What are AA scavengers?
During PET preform production, the molecule acetaldehyde (AA) is formed as a by-product of PET. Although AA is a naturally occurring substance, it has a sweet taste and can cause an “off” flavour in applications such as bottled water. This is a particular problem for non-sparkling water. To prevent this from happening, AA scavengers like Holland Colours’ TasteGuard range catch the AA and prevent its migration into the contents of the bottle, thereby safeguarding the taste.  

TasteGuardLiquid – a cost-effective liquid scavenger
The new TasteGuard Liquid is the liquid equivalent of Holland Colours’ original, bio-based, solid format TasteGuard. Being liquid-based, TasteGuard Liquid provides a true drop-in solution and a direct replacement for alternative liquid AA scavengers.

This means that PET bottle manufacturers and drink brands can switch to the new liquid TasteGuard without having to make any production line or other changes at all. And just like the first generation solid TasteGuard, the new liquid version has less impact on colours or tints. It also provides  greater effectiveness at the same dosing level as other liquid-based AA scavengers, making it a more economical option than other commercially available alternatives.  

TasteGuard Ultramax – costs down, recyclability up
Pushing the performance envelope, TasteGuard Ultramax offers a different set of advantages for bottlers and brand owners. For instance, whereas most solid and liquid AA scavengers are loaded at 40% (the first generation TasteGuard already outperforms on this measure, being loaded at up to 50%), the new TasteGuard Ultramax is loaded at up to 75%. This offers breakthrough benefits, including:  

• Lower colouring costs (less packaging, less warehouse space, less production time, less handling, long shelf-life) 
• Easier recycling with less carrier material 
• Improved compatibility with the newest generation of HPP4 and HPP5 injection moulding machines  
• No sedimentation 
• Fully customisable in colour and tint 
• Same food contact status as the first generation solid TasteGuard
• Process neutral 
• Low scrap rate and energy consumption 

Direct switching for existing TasteGuard users 
Based on a solid biobased carrier just like the first generation TasteGuard, TasteGuard Ultramax provides an easy drop-in solution for existing TasteGuard users who want to up their sustainability, lower their costs and meet upcoming EU PET bottle recycling regulations.
