Flour can only explode when it is distributed in the air. A bag of flour is not explosive, so surely that is not relevant to the OP.
I would think a simple ETD test or drug-sniffing dog would be able to quickly resolve any concern over the contents of the bag. I do agree with the suggestion of leaving it sealed in the original bag if at all possible, both to reduce hassle and general cleanliness. <shrug>
As others have mentioned, Customs (is it permitted to bring large quantities of flour, and is it taxable) and overweight luggage fees should be your primary concerns.
