Purification and Characterization of Latent Polyphenol Oxidase from Apricot (Prunus armeniaca L.)
Polyphenol oxidase from apricot (Prunus armeniaca) (PaPPO) was purified in its latent form (L-PaPPO), and the molecular weight was determined to be 63 kDa by SDS-PAGE. L-PaPPO was activated in the presence of substrate at low pH. The activity was enhanced by CuSO4 and low concentrations (≤ 2 mM) of SDS. PaPPO has its pH and temperature optimum at pH 4.5 and 45 °C for catechol as substrate. It s...
متن کاملStamen development and winter dormancy in apricot (Prunus armeniaca).
BACKGROUND AND AIMS In temperate woody perennials, flower bud development is halted during the winter, when the buds enter dormancy. This dormant period is a prerequisite for adequate flowering, is genetically regulated, and plays a clear role in possibly adapting species and cultivars to climatic areas. However, information on the biological events underpinning dormancy is lacking. Stamen deve...
متن کاملAntioxidant and antimicrobial activities of bitter and sweet apricot (Prunus armeniaca L.) kernels.
The present study describes the in vitro antimicrobial and antioxidant activity of methanol and water extracts of sweet and bitter apricot (Prunus armeniaca L.) kernels. The antioxidant properties of apricot kernels were evaluated by determining radical scavenging power, lipid peroxidation inhibition activity and total phenol content measured with a DPPH test, the thiocyanate method and the Fol...
متن کاملOsmotic Drying of Apricot (Prunus armeniaca) in Sucrose Solution
Osmotic drying is a process of partial removal of water by submersing fruits in sucrose solution. Th e goal of this paper is to examine kinetic features of osmotic drying of apricot halves in sucrose solution. For osmotic drying of apricot halves in a thick immovable layer, a planned experiment was conducted. Experimental results were used to create an empirical model of osmotic drying kinetics...
متن کاملQuality Indicators of Osmotic Dried Apricot (Prunus armeniaca)
Apricot (Prunus armeniaca) osmotic drying set of tests was conducted under controlled condition in laboratory. Current mean values of samples moisture content were obtained by measurement equipment and were used as data base for further statistical analysis. ANOVA statistical analysis proved that solution temperature and concentration are infl uential factors of osmotic drying. Empirical equati...
