Objective(s): This paper investigates the validity of Artificial Neural Networks (ANN) model in the prediction of electrospun kefiran nanofibers diameter using 4 effective parameters involved in electrospinning process. Polymer concentration, applied voltage, flow rate and nozzle to collector distance were used as variable parameters to design various sets of electrospinning ex...

Milk kefir grains (KGs) are composed of a complex symbiotic microbial mixture of bacteria and yeasts growing in kefiran, an extracellular polysaccharide substance of bacterial origin. This is the first report documenting a successful attempt at reforming KGs using pure mixed starter-cultures of microorganisms isolated from KGs, and gain insight into an otherwise hidden world. A milk pouch syste...
