13. Desenvolvimento de um adsorvente contínuo supermacroporoso de troca catiônica para recuperação de lactoferrina de soro de leite / Development of a cation exchange solid supermacroporous adsorbent for lactoferrin recovery from whey
Whey proteins have functional, nutritional and technological properties promoting their use as ingredients and supplements. Sweet whey obtained from Minas Frescal cheese production and concentrated by ultrafiltration was used in the lactoferrin capture in a supermacroporous adsorbent. Supermacroporous monolithic columns have been prepared by radical cryo-cop
