Influência do tempo de armazenamento sobre a concentração de alfa-tocoferol e gama-tocoferol em óleos vegetais

Revista do Instituto Adolfo Lutz, 2016
O alfa- e o gama-tocoferol estão entre os homólogos da vitamina E, que possui importante papel como antioxidante. As fontes dietéticas mais ricas em vitamina E são os óleos vegetais. Este trabalho avaliou os níveis de alfa- e gama-tocoferol nos óleos de canola, girassol, milho e soja, e averiguou sua variação com o tempo de armazenamento.
