Transubstantiation in modern science: How can substance change without accidents

[jim111]

The Scholastics, who accepted Aristotle's definition, also distinguished primary substance (substantia prima) from secondary substance (substantia secunda): the former is the individual thing — substance properly so called; the latter designates the universal essence or nature as contained in genus and species.
(New Advent)

So is transubstantiation a change in  substantia secunda?
