The advantages of this technology are many. It allows the
product to have a longer effective shelf life by allowing freshness
to be measured visually along the best-before date, hence
reducing margins of error. The added guarantee of product safety
for the consumers is of course of primary importance, although
wastage reduction (through more accurate estimation of bestbefore
dates) and product confidence is certainly of interest to
manufacturers and retailers, as the products must be disposed of
whether they are fit to be consumed or not when the estimated
best-before date is reached.
