By Barbara Glakas Effects of a Lysine-involved Maillard reaction on the structure and in vitro activities of polysaccharides from Longan pulp. It was showed that with the increase of Mw, the DPPH scavenging rate of longan fruit pulp wine and four LP sections was gradually increased. At least one study suggests that the potency is comparable to Ganoderic Acid (from Reishi) but this needs to be replicated; it is another promising avenue. For example, LPs could be both extracted and structurally modified by enzymatic techniques. Jiang et al.
