The tuberous root of yacon (Smallanthus sonchifolius) is a rich source of fructooligosaccharide (FOS), which has a prebiotic effect. However, FOS significantly decreases accompanying (or FOS significantly decreases with) an increase in fructose du...

Oligo-tyrosine peptides with degrees of polymerization ranging from 2 to 5 could be synthesized by α-chymotrypsin-catalyzed reaction with l-tyrosine ethyl ester in aqueous media, although the peptide yield was low due to a preferential hydrolysis ...
Tuberous roots of yacon (Smallanthus sonchifolius) accumulate about 10%, on a fresh weight basis, of inulin-type fructooligosacharides (FOSs), known as a food ingredient with various healthy benefits. However, we have a great difficulty to ensure ...
