This study aims to characterize the pectic oligosaccharides (POSs) generated from enzymatically hydrolyzed citrus peel pectin using a selected enzyme. Pectinex Ultra AFP was used depolymerize into POSs. The POSs were analyzed high-performance liquid chromatography (HPLC) and coupled with mass spectrometer (LC/MS) methodology determine composition of monosaccharides average molar distribution ba...

The major pool of peroxidase activity is present in the peel of some Egyptian citrus species and cultivars compared to the juice and pulp. Citrus jambhiri cv. Adalia had the highest peroxidase activity among the examined species. Four anionic and one cationic peroxidase isoenzymes from C. jambhiri were detected using the purification procedure including ammonium sulfate precipitation, chromatog...

In orange-pigmented citrus fruits, the xanthophyll esters are predominant carotenoids, but their biosynthetic origin is currently unknown. this work, seven PYP/XES (Pale Yellow Petal/ Xanthophyll esterase) genes were identified in Citrus genomes, only PYP1-4 and 6 contained structural domains essential for activity. The expression profiles sweet orange other species such as lemon, mandarin pumm...

Abstract Polymethoxylated flavones (PMFs), the main form of in citrus, are derived from flavone branch flavonoid biosynthesis pathway. Flavone synthases (FNSs) enzymes that catalyze synthesis flavanones. However, FNS citrus has not been characterized yet. Here, we identified two type II FNSs, designated CitFNSII-1 and CitFNSII-2, based on phylogenetics transcriptome analysis. Both recombinant C...

The peel of pummelo accounts for approximately 30% fruit weight. Pummelo which has been considered as a by-product is rich in various nutrients and functional compounds, while most the disposed wastes. utilization peels could not only result valued-added products/ingredients, but also reduce environmental threats. Essential oil, polyphenols pectin were recovered from by many ways. By mainly rev...

In the last few years, flavored beer market has increased significantly. particular, consumers showed a growing interest in citrus-flavored beers. Citrus fruits contain, among other class of compounds, terpenes and terpenoids oxygenated heterocyclic compounds. The absence specific legislation concerning production ingredients reported on labels makes these beers subject to possible adulteration...

The Papeda Citrus subgenus includes several species belonging to two genetically distinct groups, containing mostly little-exploited wild forms of citrus. However, little is known about the potentially large and novel aromatic diversity contained in these citruses. In this study, we characterized compared essential oils obtained from peels leaves representatives both three related hybrids. Usin...

Citrus is one of the major fruit crops in world and widely recognized by their nutritional, organoleptic health-related benefits fresh fruit. The genetic diversity among genus independent changes peel pulp, make definition standard maturity indexes quality. Commercial citrus industry are usually based on coloration, soluble solids, pH but relevance may differ varieties specific requirements mar...
