Re HFCS and pH
A couple of years ago Dr Rob Currie did a study of high fructose corn syrup
(HFCS) at the University of Manitoba in Winnipeg. A brief account of his
study appeared in the May issue of Bee News - published by the Alberta
Beekeepers Association. Two quotes from the article:
"Acid hydrolysis is known to result in syrup injurious to honeybees" and
"(Dr Currie) does warn beekeepers , however, to be aware of two possible
problems of off-spec HFCS: low pH (4 or lower), and a coloured syrup. Most
HFCS is colourless; coloured syrup may be an indication that it was
manufactured by acid hydrolysis"
