SUGARCANE NUTRITIONAL ANALYSIS TO ENABLE FOOD SAFETY ASSESSMENT OF GM CULTIVARS—APPROACHES TO ESTABLISHING A BASELINE
By AL RAE; GD BONNETT
GENETICALLY modified (GM) sugarcane cultivars are under development. Before these
cultivars can be grown commercially and the products derived from them used, they
will need approval by regulatory authorities. The pathway for regulation of the food
derived from genetically modified sugarcane is discussed, in particular the likely
requirements for the compositional analysis of sugarcane. Some of the components
required for analysis are not normally measured. However, using data from some of the
components of the plant that are frequently measured (sucrose, ash, nitrogen, fibre) it is possible to determine how factors such as genetics, season, geography, management
(e.g. nutrition) and time of year may affect them. From this, a strategy for sampling
crops and experiments to determine the range of values, particularly for the components
not routinely measured such as fats and protein, can be defined. This strategy will
facilitate sampling and measurement to document the range of compositions that could
be expected from existing production systems. A set of baseline measurements that can
be used for comparing the composition of GM plants to existing cultivars during the
assessment process will be the end result.
