Light-induced pigment destruction was studied in ripening apple (Malus domestica Borkh., cv. Antonovka) fruits with reflectance spectroscopy. The reflectance spectral changes attributable to light-induced transformation of xanthophyll cycle carotenoids (Car) preceded the pigment degradation. In green fruits, the destruction of chlorophyll and Car proceeded synchronously up to complete disappear...

−− Pectins are polysaccharides that act as a cellular binder in the peel of many different fruits and vegetables. An important feature of pectins is the esterification of the galacturonic acid residues with methanol. The degree of methylation is defined as the number of moles of methanol per 100 moles of galacturonic acid. The objective of the present work was to study the acid demethylation of...

Calcium deficiency in apple fruit has been identified as a primary cause of bitter pit in apples, however some apples are not as susceptible as others. The apple cultivar ‘Scilate’ has been identified as less susceptible to bitter pit, but it is not known whether high calcium concentrations are what contribute this resistance. Because scilate is a more recent variety, little research has been d...

The consumption of granola based on sweet potatoes and nuts provides a large amount vitamins, minerals, fiber water promotes the use foods with natural sweeteners, purpose this work was production potato inclusion As thickening agent, tuber whose scientific name is (Ipomoea Batata) has vitamin A, proteins which in certain way would contribute to improvement quality granola. type research quanti...

Pre-storage treatment of superficial scald-susceptible apple and pear fruits with the blocker of ethylene action 1-methylcyclopropene (1CP) inhibits the synthesis of -farnesene. Consequently, accumulation of -farnesene and its conjugated trienol (CTol) oxidation products n the fruit skin is diminished, and scald is largely prevented. In cold-stored apple fruit, a marked increase in expression o...

BACKGROUND Apples possess rich content of varied polyphenolic compounds showing a variety of biological activities that may ascribe to worthy effects against some chronic diseases. The present study was designed to assess the protective effects of the cloudy apple juice (CAJ) and apple peel extract (APE) of Egyptian Anna apple on the complications in experimental diabetes. MATERIALS AND METHO...

Meta-analyses of randomized controlled trials (RTC) have confirmed the hypocholesterolaemic effect of oats and oat based fibers. However, the mechanisms by which oats or oat fractions lower cholesterol is not totally clear. Recognizing the important role of the gut microbiome in metabolism and metabolic disease risk, we examined the impact of whole grain oat Granola (WGO) on the human gut micro...

The volatile composition of different apple varieties of Malus domestica Borkh. species from different geographic regions at Madeira Islands, namely Ponta do Pargo (PP), Porto Santo (PS), and Santo da Serra (SS) was established by headspace solid-phase microextraction (HS-SPME) procedure followed by GC-MS (GC-qMS) analysis. Significant parameters affecting sorption process such as fiber coating...

Pectinases (EC 3.2.1.15) are a class of enzymes that catalyze the depolymerization or de-esterification reactions degrade pectic substances. In present study, we have isolated Aspergillus niger strain from soil samples, in India and evaluated pectinase production. The highest producing A. was further optimized with various agricultural wastes. Plackett-Burman design (PBD) Central composite ‘(CC...

The application of peel tests for the measurement of adhesive fracture toughness of metal-polymer laminates is reviewed and the merits of a mandrel peel method are highlighted. The mandrel method enables a direct experimental determination of both adhesive fracture toughness (GA) and the plastic bending energy (GP) during peel, whilst other approaches require a complex calculation for GP. In th...
