Abstract
Aloe-based household preparations and commercial products are used
worldwide as a source of nutraceutical compounds, among which anthraquinones and
acemannan are the most known. However, it is reported that improper storage conditions
could lead to significant degradation processes, resulting in a low content of active substances.
The aim of this work was to study the stability of aloin and â-polysaccharides
in aloe-based products during storage, as a function of temperature and chemical agents
added.
Generally, aloin degradation in whole leaf homogenate was fast, and neither
ascorbate nor the antimicrobial agents could increase stability; a lower temperature
slightly improved stability, (DT50 up to 26 days at +4°C). Regarding the stability of
â-polysaccharides, a strong influence of the storage temperature was observed, while
antimicrobial agents did not show significant reduction of degradation. For both compounds,
household and commercial products were significantly more stable.
