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.

23.1 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.
