Smoking Temperature Characteristics and Influence of Quality Indicators on Phytophagus Fillet (Hypophthalmichthys Molitrix)

Abstract

The evolution of modern technologies for preserving fish and fish products has led to the eclipse of the preservation properties of many traditional methods, including the smoking method. Nowadays, the main purpose of smoking has been redirected towards highlighting the sensory quality rather than its preserving effect. The main aim of this paper is to highlight the physicochemical, sensory, and color characteristics of smoked phytophagous fillets. To produce the necessary products, nine specimens of phytophagous (Hypophthalmichthys molitrix) were harvested from the fish farm "Piscicola Vlădeni, CC&C PES SRL" Iasi, which were processed and prepared in the Microproduction Workshops of the Iasi University for Life Sciences "Ion Ionescu de la Brad". Three different smoking methods were applied to the fillets resulting from the phytophagous processing; hot smoking, semi-hot smoking, and cold smoking. From a physicochemical point of view, in the case of the batch with hot smoking quantity, a lipid content of 1.76±0.024% was recorded, higher compared to the L2ASC (0.94±0.04%) and L3AR (0.86±0.024%) batches. As regards protein content, the highest value was also found in lot L1AC (22.2±0.083%), followed by lot L2ASC (22.18±0.02%), with the lowest value in lot L3AR (21.96±0.024%). The most appreciated fillets were those processed by heat treatment with semi-warm and warm smoking.
