In infant formula, the use of DHA and ARA is challenging, as these fatty acids are prone to oxidation which may lead to off-notes in the finished formula product during shelf life.

Overcoming this challenge, two routes may be taken:

1) Directly injecting LCPUFA oils to the wet blend

2) Dry blending microencapsulated DHA and ARA oils.

There is a huge cost saving potential directly using injection of LCPUFA oils instead of using microencapsulated DHA and ARA oils. Cost saving for direct oil injection of DHA alone may easily exceed EUR 100,000 per 1000 mt of infant formula or 0.1 EUR per kg. In addition, direct LCPUFA oil injection provides superior organoleptic results and stability when correctly executed. In addition, the hygienically risky dry-blending operation may be avoided which is most important for Stage 1 products.

It is mandatory to use the highest quality DHA and ARA oils and state of the art technical implementation to obtain the desired results.

We at NutriXperts can assist you with that. Firstly, we will visit your manufacturing facility and make an assessment for the implementation. We are also able to recommend a prime quality DHA and ARA supplier.

Some areas of review for LCPUFA Direct Oil Injection: 

• Oil storage, intermediate storage, blending. 
• Oil dosing and oil injection process
• Oil emulsification
• Process flow and conditions once oil is introduced.
• Handling of Metal ions
• Antioxidants and pro-oxidants addition form and points
