DETERMINATION OF THE CAROTENOIDIC COMPOUNDS FROM POTATO TUBERS (SOLANUM TUBEROSUM)
Keywords:
potatoes, carotenoidic compounds, colorimetric method, biodynamic methodsAbstract
Determinations concerning the carotenoidic compounds content was achieved on
four potato varieties (Hansa, Sieglinde, Nicola and Linda) obtained from a German
private sources, country were this potato varieties are frequently cultivated and
consumed. The potatoes were cultivated both in the classical and biodynamic
conditions. For the carotenoids extraction was used an 80% acetone water solution,
and for the quantitative determination was used a colorimetric method based on the
specific absorption of this compounds at different wavelength. The results
interpretation was achieved with the aid of some calculus relations.
