Hi @Christa,
Thanks for reaching out. We've chosen sucralose for multiple reasons.
Sucralose was discovered in 1976 and is made from sugar. The EFSA approved of sucralose in 1991 and the FDA approved of sucralose in 1999 for general purposes. Since then, sucralose has been used in a huge and ever-growing amount of products. The European Food Safety Authority (EFSA) re-assessed the safety of sucralose especially for use in baby foods. The EFSA exists to ensure the safety of what we eat. In 2016, the EFSA released their scientific opinion following this re-assessment and have deemed sucralose safe, even for use in special medical purposes in young children.
So sucralose is safe, but why did we add it to Jake? Sucralose is about 600 times sweeter than sugar, which means that we only need very small amounts of it to sweeten foods and drinks. That means that we're able to create Jake with the level of sweetness it has, without the additional calories that sugar would add to obtain the same level of sweetness.
We keep on developing the products of Jake and currently, we're looking into Stevia as a replacement for Jake. The first samples we had, were not successful. The aftertaste of Stevia is bitter and not nice at all, so we have to find a way to make this taste better. Eventually, sucralose will be replaced, but as you can imagine, this process takes a while.
Best,
Vera
