- ItemDrying kinetics and quality characteristics of indian mackerel (Rastrelliger kanagurta) in solar-electrical hybrid dryer(Taylor & Francis Group, LLC, 2019) Murali, S.; Kumar, K.S.; Alfiya, P.V.; Delfiya, D.S.A.; Samuel, M.P.The aim of the study was to investigate the drying kinetics and quality Solar energy; hybrid dryer; characteristics of Indian mackerel dried under solar-electrical hybrid dryer modeling; drying kinetics; (S-EHD). Fresh Indian mackerel fishes (Rastrelliger kanagurta) were cleaned, quality cut into butterfly fillets, and salted overnight using a dry salting method (saltto- fish ratio, 1:3). The salted mackerel was dried in a S-EHD at the air temperature of 45-55°C, relative humidity of 47-62%, and air velocity of 0.60-0.80 m/s. Open sun drying (05D) of salted Indian mackerel was conducted to compare with S-EHD. The moisture content of the salted mackerel (61.5% w.b.) was reduced to 31.8% (w.b.) under S-EHD and 30.25% (w.b) under OSD in 8 and 32 h, respectively. The drying rate curve showed that mackerel drying occurred under falling-rate drying period in both the drying methods. A drying efficiency of 23.81% was observed for salted Indian mackerel drying under S-EHD. Diffusion approach and two-term models were selected to accurately predict the drying behavior of mackerel under S-EHD and OSD, respectively. Total volatile base nitrogen (TVB-N), trimethylamine, and thiobarbituric acid analysis of dried samples revealed that the mackerel dried under S-EHD was better than OSD. In the sensory analysis, samples dried under S-EHD recorded highest overall acceptability score.
