As clorofilas
Autor: Nivia Maria Streit, Liana Pedrolo Canterle, Marta Weber do Canto, Luísa Helena Hychecki Hecktheuer
Publikováno v: Ciência Rural, Vol 35, Iss 3, Pp 748-755 (2005)
As clorofilas são pigmentos verdes, comuns em todas as células fotossintéticas. Por sua estrutura química ser instável, são facilmente degradadas, resultando em produtos de decomposição que modificam a percepção e qualidade dos alimentos. E
