Following the above I asked Morrisons :
" Hello, Previous ref. 84760 Would it be possible to tell me if your own brand sugar contains any additives eg. anti caking agents or ant/pest deterrents, that may render it unsuitable as a winter food supplement for honey bees? Many thanks Russell Flynn"
According to Morrisons it does not contain anything other than sugar, if it did wouldn't they have to state so on the packaging?
However not everyone in the supply chain may be working off the same spec page. Leave you to draw your own conclusions.
Their reply
:Good Morning Mr Flynn,
Thank you for contacting us.
After consulting our Technical Team, I can confirm the specification indicates that the only ingredient present is sugar.
Hope this helps.
Yours Sincerely
C Ruddick
