The production of oilgosaccharides using Penicillium citrium cells at high sugar concentrations was investigated at 50$\^{C}$ and pH 5.0. Both 1-kestose and neokestose were produced form sucrose, while both nystose and tetrasaccharide were produced from 1-kestose. However, no reaction product was obatined from neogructo-oligosaccharides such as neokestos. Based on these experimental rsults, a hypothetical reaction route was proposed to illustrate how neofructor-oilgosaccharids are formed from 1-kestose.
