Edible coating of whey protein concentrates for fishery products and procedure for obtaining it.

Edible coating obtained with whey protein concentrates to protect fishery and aquaculture products during their frozen storage, obtaining procedure and use. The coating is a water soluble edible liquid composed of an aqueous mixture of whey protein concentrate, optionally with sorbitol and/or glycerol. The process for obtaining the coating comprises a mixing stage of the components, followed by a heating stage and a cooling stage. The use or application of the coating consists of coating by immersion of the fishery and aquaculture products, still in a fresh state or already frozen, in the liquid coating, subsequently keeping them frozen. The edible coating acts as a protection, particularly against lipid oxidation, which extends the preservation of fishery and aquaculture products stored frozen.
