Molecular characterization of exopolysaccharide from Periweissella beninensis LMG 25373 and technological properties in plant-based food production.

Periweissella beninensis LMG 25373, belonging to the recently established Periweissella genus, exhibits unique motility and high adhesion capabilities, indicating significant probiotic potential, including resilience under simulated gastrointestinal conditions. This study demonstrates for the first time that P. beninensis LMG 25373^T produces a dextran-type exopolysaccharide (EPS) with a distinctive high degree of branching (approximately 71 % of α-(1 → 6)-linkages and 29 % α-(1 → 3)-linkages).

New enzyme-based method for analysis of water-soluble wheat arabinoxylans.

Arabinoxylans (AX) are the predominant cell-wall polysaccharides in wheat flour. Water-extractable AX are essential for dough and bread properties and performance. However, there is no specific and accurate way of determining the content and structure of AX.
