Effects of drying technique on the quality of Mola (Amblypharyngodon mola) dried by solar tent dryer and open sun rack dryer

Abstract

Quality change of Mola (Amblypharyngodon mola) from open sun rack and solar tent dryer was evaluated at 1st, 2nd and 3rd days of drying. Sensory analysis showed that, solar tent dryer dry fish were excellent in overall quality of dry fish from open sun rack dryer. Moisture content of Mola from solar tent dryer was significantly (p>0.05) lower than the moisture content of dry fish from open sun rack dryer. Protein, lipid, ash and TVB-N content was significantly (p>0.05) higher in solar tent dried fish than dried fish from open sun rack. However, microbial load was higher on dry fish obtained from open sun rack dryer compared with the dry fish from low coat solar tent dryer. Moreover, the quality of the dried fish products from solar tent dryer was excellent in quality compared to the dried fish from open sun rack dryer.

Proximate composition, mineral content, peroxides and rancidity in open sun and solar-tent dried small sardine fish in Malawi

“…Results from previous studies are mixed. Solar tent dryers are superior to open sun drying for the majority of studies (Al-Azawiey and Hassan, 2016;Banda et al, 2017a, b;Cyprian et al, 2017;Zebib et al, 2017;Likongwe et al, 2018;Patterson et al, 2018;Lithi et al, 2020). A few other studies have found no differences.…”

Drying Klunzinger's mullet fish Planiliza klunzingeri using Halogen Dryer and modeling the moisture content with artificial neural network

“…Kumar (2015) and Al-Temimi ( 2018) indicated that the moisture content of fish carp was reduced with an increase of the energy levels when the microwave dryer was used, which led to reduce the drying time. Lithi et al (2020) stated that the moisture content of fish was decreased from 80.71% to 7.5% by using solar dryer and reduced to 7.86% using open sun drying. Tanuja et al (2020) disclosed that the moisture content of the fish (Stolephorus commersonii) reduced from 81.97% to 28.87% and 34.43% by the solar rack dryer and natural sun drying respectively.…”

“…These results were agreed with Al-Temimi ( 2018) who found that the ash content in microwaved dried carp was decreased during the storage periods. Lithi et al (2020) mentioned that the ash content in dried fish reached 9.60% and 10.16% using open sun drying and solar dryer respectively. The ash content in open sun dried fish was significantly higher because of deposition of dust and dirt particles on the fish (Rasul et al, 2018).…”

“…Al-Fadhli (2009) dried Thelah fish (Scomberoides commersonnianus) using a solar dryer. Lithi et al (2020) studied quality change of Mola (Amblypharyngodon mola) in open sun drying and solar tent dryer, the researchers found that the moisture content of Mola from solar tent dryer was significantly (P<0.05) lower compared to the open sun rack dryer and protein, lipid, ash and TVB-N content was significantly (P<0.05) higher in solar tent dried compared to the open sun rack dryer. Hardoko & Utami (2020) declared that the boiling time and drying duration had an effect on the chemical-physical properties of the rambak crackers of white snapper fish skin.…”
