The effect of nitric acid extraction variables on orange pectin
1992
Aravantinos-Zafiris | Oreopoulou, V.
Pectin was extracted from dry orange waste with nitric acid. A factorial experimental design was used and the effects of temperature, time and pH of extraction on pectin yield and 'jelly units', ie pectin yield X viscosity of pectin solution were determined. Optimum conditions for pectin extraction are also discussed. According to ash and methoxyl content determinations the product can be classified as low ash and high methoxyl pectin. Its purity expressed as anhydrogalacturonic acid content varied from 68.5 to 75.0%.
