HC Deb 23 January 1941 vol 368 cc326-7W
Mr. Stokes

asked the Parliamentary Secretary to the Board of Trade, as representing the Ministry of Food, whether he is aware that one ounce of wholemeal bread contains 25 to 30 units of Vitamin B; and whether lie will state how many units of white synthetic vitamin B it is proposed to introduce into the white flour necessary for one ounce of white bread?

Mr. Johnstone

I have been asked to reply. My Noble Friend is advised that wholemeal bread made from a 100 per cent. extraction flour contains about 28 units of vitamin B1 per oz., but that bread made from such a flour is not fully digested. Bread made from flour of 85 per cent. extraction, which it has been decided to adopt as the minimum for a wholemeal flour, will contain about 20 units of vitamin B1 per oz. It is proposed to add vitamin B1 to white flour in sufficient quantity to raise the vitamin B1 content of white bread also to 20 units per oz.
