22.3 Recommendations
There are no publications for methods of analysis for stearoyl lactylates. This is therefore an area that requires method development and it should be ensured that
the methods are applicable to desserts, dairy-based drinks, infant formulae and weaning foods.

23 E483: Stearyl tartrate
23.1 Introduction
The major food groups contributing to dietary intake of stearyl tartrate are fruit- based desserts, cakes, cookies and pies, and other fine bakeryware with the
maximum permitted level of 5 000 mgkg being allowed in desserts. The accept- able daily intake ADI for stearyl tartrate is 20 mgkg body weight.
