Dual degree (BEng/BSc) - most useful science major?

[MourningTide]

Hi guys I am interested in studying chemical engineering at university next year and also want to do a double degree with a bachelor of science.
However I am having a hard time deciding what major would be the most useful...any advice would be greatly appreciated.

Possible Majors (that interest me):
Biochemistry and Molecular biology
Biomedical science
Chemistry
Maths
Physics

My primary interests as a chemical engineer will be working in the biochemical/biomedical, pharmaceutical or fuels industry.
Cheers
