Determination of Post-Harvest Biochemical Composition, Enzymatic Activities, and Oxidative Browning in 14 Apple Cultivars

Enzymatic browning and antioxidant activities in harvested litchi fruit as influenced by apple polyphenols.

'Guiwei' litchi fruit were treated with 5 ga.i. L(-1) apple polyphenols (APP) and then stored at 25°C to investigate the effects on pericarp browning. APP treatment effectively reduced pericarp browning and retarded the loss of red colour. APP-treated fruit exhibited higher levels of anthocyanins and cyanidin-3-rutinoside, which correlated with suppressed anthocyanase activity. APP treatment al...

Post Harvest Physical and Nutritional Properties of Two Apple Varieties

Nondestructive Determination of ‘golden Delicious’ Apple Quality and Harvest Maturity

The usefulness of nondestructive methods for measuring chlorophyll content in skin of ‘Golden Delicious’ apples and for evaluating quality parameters and fruit maturity using optical reflectance spectrometry was studied. The fruit weight, firmness, total soluble solids content and titratable acidity during vegetation period and short-term storage at 10°C of ‘Golden Delicious’ apples were measur...

Evaluation of Post-Harvest Disease Resistance in Blackberry Cultivars

Seventeen blackberry cultivars were evaluated for postharvest fruit-rot resistance in June and July, 2003. Fully mature, undamaged berries were harvested on two dates for each genotype at the University of Arkansas Fruit Substation, Clarksville. After transporting in chilled coolers to the Plant Pathology Department in Fayetteville, two replications of 10 berries of each genotype were placed in...

Traditional versus modern apple cultivars – a comparison of juice composition

Apples are rich in components that are important for human health, such as polyphenols, organic acids and microelements, but their chemical composition varies with different apple cultivars. We aimed to find out if there is any superiority in traditionally grown apple cultivars in terms of their fruits’ bioactive components content. Juice from two traditionally grown apple cultivars, ‘Mutsu’ an...
