Chitosan aspalathin stabilization matrix: SuntoryRecent Research Landscape

Oxidative degradation of ascorbic acid in aqueous solutions leads to rapid nutrient loss and discoloration. Chitosan-based complexation stabilizes the molecule to extend shelf life in containerized formats.

What technical problems is Suntory addressing in Chitosan aspalathin stabilization matrix?

Active ingredient precipitation instability

(11)evidences

Bioactive compounds in liquid formulations lose potency and sensory quality when exposed to oxygen and light during storage. Preventing this degradation ensures shelf-life stability and functional efficacy.

Beverage color and nutrient degradation

(6)evidences

Ascorbic acid is highly unstable in aqueous solutions and prone to rapid oxidation during storage. Preventing this chemical breakdown maintains nutritional integrity and shelf life in commercial packaging.

Oxidative beverage degradation

(4)evidences

Active compounds in non-fermented and semi-fermented tea beverages are highly susceptible to oxidation and browning during storage. Preventing this chemical instability maintains the beverage's nutritional profile and sensory quality.
