Physico-chemical and structural changes of red-fleshed dragon fruit (Hylocereus polyrhizus) during fruit development.
BACKGROUND Determination of physico-chemical (weight, length, diameter, stomatal density, respiration rate, colour, soluble solids concentration, titratable acidity, chlorophyll and betacyanin content) and structural changes of red-fleshed dragon fruit (Hylocereus polyrhizus (Weber) Britton & Rose) was carried out from 5 to 35 days after pollination (DAP) in order to explain their growth, devel...
متن کاملMicroencapsulation of Dragon Fruit (Hylocereus polyrhizus) Peel Extract Using Maltodextrin
Dragon fruit peel can be utilized as a natural dye due to betacyanin content, redviolet pigment of betalain group. Betacyanin is unstable to temperature, oxygen, and light, consequently microencapsulation technology is required to maintain its stability. This study aims to determine microencapsulation efficiency of dragon fruit peel extract with variation of encapsulation ratio and to perceive ...
متن کاملPigment identification and antioxidant properties of red dragon fruit (Hylocereus polyrhizus)
The aim of this study was to identify pigments present in the red dragon fruit (Hylocereus polyrhizus) and to further investigate the antioxidant properties in this fruit. Pigment was identified using the High Performance Liquid Chromatography (HPLC) and results confirmed the presence of betanin in sample at a retention time of 11.5 min which corresponded to the retention time of the betanin st...
متن کاملIsolation and identification of myo-inositol crystals from dragon fruit (Hylocereus polyrhizus).
Crystals isolated from Hylocereus polyrhizus were analyzed using four different approaches--X-ray Crystallography, High Performance Liquid Chromatography (HPLC), Liquid Chromatography Tandem Mass Spectrometry (LC-MS/MS) and Nuclear Magnetic Resonance (NMR) and identified as myo-inositol. The X-ray crystallography analysis showed that the unit-cell parameters were: a = 6.6226 (3) Å, b = 12.0462 ...
متن کاملPhysico-chemical properties of spray-dried red pitaya (Hylocereus polyrhizus) peel powder during storage
The physico-chemical properties of spray-dried pitaya peel powders kept at accelerated (45 ± 2°C) and room temperature (28 ± 2°C) for 14 weeks and 6 months, respectively were evaluated. Changes in physico-chemical properties of the peel powder were used as indicators of stability, while changes of the betacyanin pigment retention was used to calculate the shelf-life of the powder. Storage tempe...
