This research carried out to study the effects of probiotic coating alginate and whey protein with Pediococcus acidilactici and Lactobacillus plantarum to increase the storage of rainbow trout fillet (Oncorhynchus mykiss) at refrigerated temperature and to evaluate the physical characteristics of the fillets. Thus, the physical parameters such as color and texture of fillets were investigated at 0, 7, 14 and 21 days. Results showed that, the color index (L*, a*, b*) and texture index (hardness cycle, deformation at hardness, and firmness) in treated fillets were better than control. In other words, the use of probiotic coating caused a decrease in the index of redness of the fillet on the 21st day; on the other hand, the yellowness index was lesser. In terms of texture indices such as hardness cycle, deformation at hardness, and firmness, using probiotic coatings in higher percentages of alginates and whey protein resulted in better preservation of fillet tissue quality than other treatments.
