Mathematical modeling of convective air drying of quinoa-supplemented feed for laboratory rats BABT
Vega-Gálvez,Antonio; Dagnino-Subiabre,Alexies; Terreros,Gonzalo; López,Jessica; Miranda,Margarita; Di Scala,Karina.
Drying kinetics of quinoa-supplemented feed for laboratory rats during processing at 50, 60, 70, 80 and 90ºC was studied and modeled in this work. Desorption isotherm was obtained at 60ºC giving a monolayer moisture content of 0.04 g water/g d.m. The experimental drying curves showed that drying process took place only in the falling rate period. Several thin-layer drying equations available in the literature were evaluated based on determination coefficient (r²), sum squared errors (SSE) and Chi-square (χ2) statisticals. In comparison to the experimental moisture values, the values estimated with the Logarithmic model gave the best fit quality (r² &gt;0.994, SSE < 0.00015 and χ2 < 0.00018), showing this equation could predict very accurately the...

Evaluation of apple pomace based reconstituted feed in rats after solid state fermentation and ethanol recovery BABT
Devrajan,A.; Joshi,Vinod K.; Gupta,Kuldeep; Sheikher,Chander; Lal,Brij B..
To utilize apple pomace in an economical and effective way, a feed was developed by solid state fermentation (SSF) using sequential interactive co-culture of Candida utilis and Kloeckera. Removal of ethanol and drying of the left - over residue. Feeding trial was conducted in white albino rats before and after reconstitution of apple pomace feed in the choice and no choice study. Feeding of apple pomace feed in the rats before reconstitution indicated that neither in fermented nor in unfermented form it was acceptable. In the no choice study both in 100% fermented and unfermented apple pomace group feed intake decreased continuously resulting in death of rats apparently due to decreased digestibility owing to high fibre content. Further, fermented or...
