Abstract

Protein-polysaccharide interactions have been a focus of scientific attention. This study aimed to improve the antioxidant and hepatoprotective effects of buffalo total milk proteins and whey protein hydrolysate (WPH) through noncovalent interactions with Psyllium husk (ispaghula) mucilage (PHM) and Nabq mucilage (NabM). Chemical composition, phenolic content, and antioxidant activities of milk protein-mucilage complexes were explored. The effects of resulting complexes on liver function, hyperlipidemia, and histopathology of the liver in rats fed high-fat diet (HFD) were investigated. The results showed that the complexes exerted significant effect on normalizing tested parameters; WPH-NabM had the most significantly decreased level of malondialdehyde content and the liver histopathological examination proved an improvement in all groups fed with these complexes. These complexes can be used as functional protection elements against the nonalcoholic fatty liver disease. PRACTICAL APPLICATIONS: PHM, NabM, and their complexes with milk proteins were proved to improve liver function, enhancing most of its measurable parameters and also diminishing the risk of cardiovascular disease. Mice with HFD achieved better health circumstances by combining these ingredients in their diet. Knowing how much these diseases proliferate in the western world and its correlation with high-fat consumption and modern lifestyle, its conjugation with PHM/NabM-MP complexes may reduce the negative impact of unhealthy food intake and, on some parameters, even improving the whole liver function. For that reason, the present study supports and pushes forward the dissemination and consumption of ispaghula or Nabq (the polysaccharides sources) or supplements originating from them. Although many interactions concerning milk proteins have already been analyzed, our study also proposes the interaction with bioactive polysaccharides as useful, opening a field of research aimed at the better application of milk proteins.

Keywords: Psyllium husk; Nabq mucilage; dyslipidemia; histopathology; liver function; milk proteins.
