Physicochemical, microstructural, and microbial qualities of dehydrated Tuna chunks: Effects of microwave power and drying methods

Abstract: Boneless Tuna chunks were marinated using spices and were dried in a microwave vacuum dryer at different powers (600 W [T1], 650 W [T2], and 700 W [T3]) for 2 hr. Another two batches were prepared by hot air drying (55 ± 5°C) (HAD) and sun drying (SD) to a comparable moisture content obtained by sample T2. The moisture content was 44.69 g/100 g, 39.26 g/100 g, 24.40 g/100 g, 32.80 g/100 g, and 38.45 g/100 g for T1, T2, T3, SD, and HAD, respectively. Increasing microwave power level resulted in reduced moisture… Show more

“…This study proves that microwave sterilization is more effective in preserving unsaturated fatty acids (UFA) and can increase their content by up to 9.14% compared with retort. Other researchers have also reported that microwave technology can reduce the degree of fatty acid oxidation [51][52][53]. It is widely accepted that the use of microwaves can reduce the exposure time of food to high temperatures, leading to the advantage [54,55].…”

“…The microwave technology has also been used as an enhancer for drying procedures of fish. Pankyamma et al (2021) evaluated the effects of different drying methods on marinated boneless tuna chunks. The authors studied microwave vacuum drying at different powers (600, 650, and 700 W) and compared it to sun drying and hot air drying.…”

“…Microwave heating uses electromagnetic waves, typically at a frequency of 2.45 GHz, to penetrate the material and generate heat through the excitation of molecules, particularly polar molecules like water. The heat is generated from within the material itself rather than being conducted from an external source, which can lead to more uniform and faster heating than conventional methods (Lee et al., 2021; Pankyamma et al., 2021).…”

“…(Chandrasekaran et al, 2013). Recent studies have shown that microwaves can be combined with other processing methods and subsequently applied to marinated meat products (Jantaranikorn et al, 2023;Pankyamma et al, 2021;Wang et al, 2022). For instance, Wang et al (2022) studied the flavor attributes of marinated pork belly cooked using conventional pan-heating, microwave heating, and microwave coupled with conduction heating.…”

“…Also, microwave heating may expedite the breakdown of proteins and the thermal destruction of ribonucleotides, resulting in larger concentrations of free amino acids and nucleotides compared to conventional thermal heating. Pankyamma et al (2021) investigated the effects of microwave power and drying techniques on the quality of tuna chunks marinated with salt, chili powder, turmeric powder, and pepper powder. The samples marinated and dried at 700 W displayed excellent rehydration capabilities and enhanced microbiological stability, although lipid oxidation was increased in the same samples.…”
