Oil Uptake Lessening and Functionality Amelioration of Deep-Fried Fish Fillets Using Egg White Protein Edible Coating

This study aimed to develop an edible egg white protein coating to reduce fat uptake and mitigate protein oxidation in deep-fried Labeo rohita fillets. Fillets (4 × 4 × 2 cm) were coated with 2.5–25% egg white protein and analyzed for proximate composition, frying yield, coating pickup, protein solubility, water-holding capacity, carbonyls, sulfhydryl groups, texture, colour, and sensory attributes. Increasing coating concentration improved coating pickup (2.65–8.36%), frying yield (70.45–80.26%), and reduced fat uptake (9.67–48.66%), while offering partial oxidative protection. Sensory evaluation identified 15% egg white protein coating as most acceptable, and it also effectively lowered fat absorption while preserving protein quality, yielding a healthier fried fish product.
