The application of the biocontrol agent Pantoea agglomerans EPS125 to unwounded fruits was practically ineffective for control of postharvest blue mould caused by Penicillium expansum when the treatment and subsequent wounding and pathogen inoculation were separated by periods of unfavourable conditions. This was due to a rapid decrease in viability of the alocthonous introduced biocontrol agen...

This study represents the first paper of the effects of growth regulators on the physiochemical and phytochemical properties of the wax apple fruit, a widely cultivated fruit tree in southeast Asia. Net photosynthesis, sucrose phosphate synthase (SPS) activity, peel color, fruit firmness, juice content, pH value, total soluble solids (TSSs), and the sugar acid ratio were all significantly incre...

PURPOSE The scientific experiments with new immunological methods (immunoblotting, RAST inhibition) and isolation of recombinant allergens suggest structural similarities in the allergenic components responsible for cross-reactions. Immunochemical and molecular biology studies indicate that epitopes of major allergen (Bet v 1, Mal d 1) contain more IgE binding epitopes than minor allergens (Bet...

The chilling conditions of apple cold storage can provoke an economically significant necrotic peel disorder called superficial scald (scald) in susceptible cultivars. Disorder development can be reduced by inhibiting ethylene action or oxidative stress as well as intermittent warming. It was previously demonstrated that scald is preceded by a metabolomic shift that results in altered levels of...

Polyphenols are antioxidant ingredients in apples and are related to human health because of their free radical scavenging activities. The polyphenolic profiles of old and new apple cultivars (n = 15) were analysed using high-performance liquid chromatography (HPLC) with diode array detection (DAD). The in vitro antioxidant capacity was determined by total phenolic content (TPC) assay, hydrophi...

Apples are an important component of the diet and used in food industry production products beverages. The aim study was to determine changes biochemical composition physicochemical properties apples stored a controlled atmosphere. We studied (sugars, ascorbic acid, soluble solids, titratable acidity) (color coordinates, peel, flesh firmness) apple samples before placing them atmosphere chamber...

Modern non-destructive optical-reflectance-based techniques for estimation of pigment (chlorophyll, carotenoid, anthocyanin, and flavonol) contents, the rate of onand off-tree ripening as well as for detection of common physiological disorders, such as sunscald, superficial scald, and water core, and other damages to apple fruit are reviewed with an emphasis on the methods developed by the auth...

Water-soluble apple peel polysaccharides (APP) and apple flesh polysaccharides (AFP) were isolated from Pink Lady fruits, and their in vitro antioxidant capacities were characterised by DPPH(), HO(), and O(2)(-) systems, and ferric-reducing antioxidant power assay. Oral administration of APP at 250 and 500 mg/kg bw in mice was shown to be as effective as AFP in lowering the CCl(4)-caused increa...

Quercetin and quercetin glycosides are physiologically active flavonol molecules that have been attributed numerous health benefits. Recovery of such molecules from plant matrices depends on a variety of factors including polarity of the extraction solvent. Among the solvents of a wide range of dielectric constants, methanol recovered the most quercetin and its glycosides from dehydrated 'Idare...

Case report We report the case of a 28-year-old female who developed acute generalized urticaria and facial angioedema one hour after ingesting grapes of several varieties. The reaction was treated at Emergency Room level with parenteral administration of corticoids and anti-histamines. She previously ingested grapes and other fresh fruits with no reaction and denied rhinitis complaints. Skin p...
