The Australian Sultana industry uses a visual assessment to classify sultanas,
based on overall colour and relative uniformity of colour within a
representative sample of 100 berries. A technique that gives a more precise
indication of fruit quality is required by the industry. A key requirement is the
rapid assessment of fruit after processing, to enable the processor to more
readily meet the requirements of the buyer. The intention is to also meet the
increasing demand of consumers who are becoming increasingly discerning
and regulators who require more detailed nutritional information provided on
food packaging.
