The natural syrups exhibited a wide range of colours regardless
of their origin. The agave syrups showed a wide range of light
absorbance (0.017–3.956) and exhibited a variety of colour categories
from water white to dark amber (Fig. 1D). The corn syrups
exhibited only the water white colour (absorbance < 0.0945). The
honey exhibited colours ranging from water white to light amber
(absorbance from 0.034 to 0.652). The sugar cane syrups displayed
the darkest colours, ranging from amber to dark amber (absorbance
from 1.471 to 3.956).
