- Abstract
This study investigated the synergistic impact of montmorillonite (MMT) and starch nanocrystals (SNCs) on gluten-loaded chitosan films, influencing the shelf stability of fresh paneer. The combination of chitosan in gluten and SNCs/MMT yielded films with uniform rheology, showcasing superior water resistance, mechanical strength, surface morphology, and antioxidant properties. Notably, compared to unpackaged paneer, those wrapped in these nanocomposite films exhibited an extended shelf life. Films produced from MMT/chitosan (GML2) retained higher moisture (68.37 to 53.12%) and titratable acidity (0.17 to 2.12%) compared to other samples. Consequently, textural properties, including hardness, springiness, chewiness, and gumminess, correlated with moisture loss, affirming the wholesomeness of paneer packaged in GML2, followed by SNCs/chitosan (GSL2). The longer shelf-life of paneer was co-related with minimal increase in free fatty acids and tyrosine content of GML2 and GSL2, lead reduced lipolysis and proteolysis. The microbiological analysis demonstrated the resilience of paneer in GML2 and GSL2, with total yeast/mold count (4.00 logCFU/g and 5.00 logCFU/g) and total plate count (6.00 logCFU/g and 6.00 logCFU/g) maintained up to the 12th day. Overall, physico-chemical attributes confirmed the superior physical and nutritional quality of paneer packaged in GML2 and GSL2 compared to the control, effectively preserving its freshness for 12 days. Highlights: Gluten-based films reinforced with MMT/chitosan and SNCs/chitosan were developed. Novel Gluten-based Bionanocomposites enhance the shelf stability of Paneer. MMT/chitosan and SNCs/chitosan demonstrated textural stability in Paneer. Bionanocomposites preserved paneer in fresh condition for up to 12 days.
