dc.description.abstractBIOFOAMS ARE A CHALLENGE FOR SCIENTISTS IN TERMS OF INNOVATION. INCORPORATION OF CELLULOSE FIBRILS (CF), MIGHT HELP IMPROVE THE MICROSTRUCTURE OF FOAMS, THUS THIS STUDY FOCUSES ON STUDYING THE IMPACT OF CF ON THE FOAMING PROPERTIES AND RHEOLOGY OF LENTIL PROTEIN (LP) FOAMS AT VARIOUS PH AND CF CONCENTRATIONS. ADDITIONALLY, LP-CF MIXTURES WERE TRANSFORMED INTO SOLID FOAMS, AND THEIR MICROSTRUCTURE, PHYSICAL PROPERTIES, AND MORPHOLOGY WERE EVALUATED. CF CONCENTRATION SIGNIFICANTLY IMPACTED ON LP-CF FOAM PROPERTIES, PRIMARILY DUE TO HIGH VISCOSITY VALUES. INCREASED CF CONCENTRATION RESULTED IN IMPROVED FS VALUES (UP TO 77 MIN) AT ALL PH VALUES. THIS IS LIKELY ATTRIBUTED TO ASSOCIATIVE INTERACTIONS AND COACERVATES FORMATION. ALSO, FOAM MICROSTRUCTURE COULD BE RELATED TO APPARENT VISCOSITY, SUGGESTING THE ROLE OF VISCOSITY IN PRESERVING THE INTEGRITY OF THE WET FOAM STRUCTURE DURING FREEZING AND LYOPHILIZATION PROCESSES. HOWEVER, ELEVATED VISCOSITY VALUES MIGHT NEGATIVELY IMPACT PROPERTIES SUCH AS FOAMING CAPACITY AND PRODUCE DENSER MICROSTRUCTURES. THE MICROSTRUCTURE AND MORPHOLOGY ANALYSIS REVEALED THAT CERTAIN FOAMS EXHIBITED A SPONGE-LIKE STRUCTURE WITH OPEN PORES AND SEMI-SPHERICAL SHAPES, SUPPORTED BY CF FIBERS EXTENDING AND FORMING LAYERS. HOWEVER, THE STRUCTURE ITSELF WAS IRREGULAR. WHILE OTHERS EXHIBITED NON-UNIFORM, IRREGULAR PORE SIZE, AND SHAPE, ALONG WITH A DENSER STRUCTURE. THESE FINDINGS CONTRIBUTE TO UNDERSTANDING THE BEHAVIOR OF LP-CF MIXTURES, ALTHOUGH ADDITIONAL INVESTIGATIONS ON MECHANICAL PROPERTIES, BIODEGRADABILITY, AND HYDROPHOBICITY ARE NECESSARY TO REACH THEIR FULL POTENTIAL FOR VARIOUS APPLICATIONS.
