Wines derived from the genetically modified wine yeast Saccharomyces cerevisiae
Health Canada has notified Dr. Hennie van Vuuren of the University of British Columbia that it has no objection to the food use of a genetically modified wine yeast, Saccharomyces cerevisiae ML01, for use in winemaking in Canada, and of wines derived from the use of this yeast. The Department conducted a comprehensive assessment of wine yeast ML01 according to its Guidelines for the Safety Assessment of Novel Foods. These Guidelines are based upon internationally accepted principles for establishing the safety of foods with novel traits.
Why rejected in SA?
PAL = Phenylalanine ammonia-lyaseC4H = Cinnamate 4-hydroxylase4CL = CoA-ligaseVST = Resveratrol synthase
SHIFT IN RESEARCH TOWARDS BIOLOGICAL PRESERVATIVES
Leucocin activity against Listeria
Glucose oxidase activity
…and can WE afford to ignore a technology with such innovation potential?
