Sabanci, Serdal; Kaya, Kübra; Göksu, Ali
The ohmic heating process is one of the novel electrical heating methods that are considered as fast, homogeneous and efficient heating. In this study, the details of the relationship between electrical conductivity (EC)-Temperature (Temp) and EC-pH-Temp at different Total Soluble Solid Content (TSSC) and different pH values were examined. Especially, the study explains details of the electrical conductivity value due to pH change (2, 2.5, 3, 3.5) and expressing EC change depending on the pH value of fruit and vegetable juices. At constant pH, EC values decrease with increasing TSSC values (10%, 20%, 30%, 40%, 50%, 60%) and decrease with increasing pH at constant TSSC value. When the relationship between Temp-EC is analyzed that the EC value increases as Temp increases in all cases and this increase is linear. It was found that the Temp-EC relationship was in high compatibility with an R2 value above 0.97. Also, in the Temp-EC-pH relationship, the R2 value was found to be an acceptable value above 0.95.

İncele - MakaleAçık Erişim2021Scopus SJRQ2The comparisons of fatty acid composition in some anaerobic gut fungi neocallimastix, orpinomyces, piromyces, and caecomyces
Kar, Bülent; Özköse, Emin; Ekinci, Mehmet Sait
The objective of this study were to identify the fatty acid composition for decanoic (C10:0), tridecanoic (C13:0), myristic (C14:0), pentadecanoic (C15:0), palmitic (C16:0), stearic (C18:0), oleic (C18:1n9c), linoleic (C18:2n6c), arachidic (C20:0), arachidonic (C20:4n6), heneicosanoic (C21:0), erucic (C22:1n9) and Cis-4,7,10,13,16,19-docosahexaenoic (C22:6n3) acids by Neocallimastix, Orpinomyces, Caecomyces and Piromyces species of rumen fungus during in vitro culture. Fatty acid (FA) profile of anaerobic fungi comprises carbon chains of length ranging from 10 to 22 were analyzed as methyl esters. Analysis of fatty acids was performed using Gas Chromatography-Mass Spectrophotometer (GC-MS). FA measures are presented as proportions of relative amounts (% total fatty acid). The highest amounts of fatty acids for all samples were found as myristic (C14:0) acid. The tridecanoic (C13:0) acid represented the second abundant FA in the fungi in all experimental groups. Stearic acid (C18:0) was the third major fatty acid for isolates investigated in the current study. In addition, another fatty acid was palmitic (C16:0) acid with relative amount representing >20% of total FA in all samples. Pentadecanoic (C15:0) acid could not be found in any other samples except Orpinomyces sp. (GMLF5). It is concluded that biohydrogenation of fatty acid composition by anaerobic gut fungi are very variable.
