Edible films from residual delipidated egg yolk proteins

Abstract

Commercial extraction with organic solvents of valuable lipids from egg yolk produces a highly denatured protein waste that should be valorized. In this work, the delipidated protein waste remaining after ethanol extraction was used to prepare edible films. This material was also treated with transglutaminase, obtaining films that have also been characterized. When compared with gelatin and caseinate edible films, the films made with egg yolk delipidated protein showed poorer mechanical properties, but improved light barrier properties, low water solubility and a high degree of transparency. It is particularly interesting that the presence of phosvitin in the egg yolk gives the films important ferrous chelating properties. When the egg yolk delipidated protein was treated with transglutaminase, the strength of the film was improved in comparison with films made with untreated protein. Finally, addition of thymol and natamycin in the preparation of these films is shown to be an interesting alternative, providing them with antibacterial and antifungal capacities.

Antifungals (ASM)

An antifungal, also known as an antimycotic medication, is a pharmaceutical fungicide or fungistatic used to treat and prevent mycosis such as athlete's foot, ringworm, candidiasis, cryptococcal meningitis, and others. Discover the latest research on antifungals here.
