Sensory and Consumer Evaluation of Kiwifruit (Actinidia deliciosa ‘Hayward') Produced Under Different Pollination Techniques

0
No votes yet
Your rating: None

Kiwifruit producers aim to obtain a large fruit production under healthy and environmentally-friendly growing conditions, with kiwifruits weighing more than 90 g/unit but maintaining adequate sensory quality. In Actinidia deliciosa ‘Hayward’, the final size of the fruit is closely related to the number of seeds per fruit, which depends on the number of ovules in flowers and the number of pollen grains that reach the stigmatic surface.

Processing of Fresh-Cut Tropical Fruits and Vegetables: A Technical Guide

0
No votes yet
Your rating: None

Fruit and vegetable production and consumption in Asia and the Pacific region have shown a marked upward trend over the past several years. Rising consumer demand in the region has come with greater awareness of food safety issues and increased need for convenience and quality. The fresh-cut produce sector has responded to these demands, and is currently at different stages of development across the region.

Inhibition of Loquat Enzymatic Browning by Sulfydryl Compounds

Your rating: None

The effectiveness of a series of sulfhydryl compounds in inhibiting polyphenoloxidase (PPO) activity in a model system (chlorogenic acid solution) and in loquat juices was evaluated.Application of different concentrations of sulfhydryl compounds to chlorogenic acid solution and fresh loquat juice showed that l-cysteine appeared to be an effective browning inhibitor.The required concentration of l-cysteine for 90% browning inhibition depended on loquat cultivars, and ranged from 0.6 mM for ‘‘Nagasaki’’ to 2.0 mM for ‘‘Yukawa’’ or ‘‘

Maintaining Quality of Litchi Fruit with Acidified Calcium Sulfate

0
No votes yet
Your rating: None

The effect of acidified calcium sulfate (ACS) on the quality of litchi (Litchi chinensis Sonn. cv. ‘Brewster’) fruit after harvest was evaluated. ACS at 1.25% or higher concentrations significantly inhibited the activities of polyphenol oxidase and peroxidase in the pericarp during storage at both 5 and 10 C. These treatments also effectively prevented browning and retained the red color of the outer shell of the fruit. Total phenolic and total anthocyanin contents in pericarp were increased by ACS treatments in a dose-dependent manner.

Chlorophyll Fluorscence Imaging Allows Early Detection and Localization of Lemon Rind Injury following Hot Water Treatment

0
No votes yet
Your rating: None

Green lemons (Citrus limon (L.) Burm.) were imaged for chlorophyll fluorescence (CF) 30 minutes after immersion of the fruit into 55°C water for 5 minutes to determine if CF could be used to identify areas of hot water-induced rind injury before the appearance of visible symptoms. Fluorescence was variable in intensity over the surface of the rind with defined areas of enhanced fluorescence being present that corresponded in shape and location with visible injury that later developed during 24 hours of storage.

Postharvest CO2 and Ethylene Production and Quality Maintenance of Fresh-Cut Kiwifruit Slices

No votes yet
Your rating: None

The quality attributes and gas production of fresh-cut kiwifruit slices (Actinidia deliciosa cv. Hayward) were studied to identify the optimum ranges of storage temperature, relative humidity, and atmospheric composition. Also the effects of wounding, C2H4 addition or removal, and chemical treatments (calcium, ascorbic acid, citric acid) on deterioration rate were investigated. Flesh softening was the major quality loss of stored fresh-cut kiwifruit slices.

1-MCP Inhibits Kiwifruit Softening During Storage

0
No votes yet
Your rating: None

Minimizing flesh softening after harvest is the key to successful long-term kiwifruit storage. Delaying kiwifruit softening reduces decay and extends kiwifruit market life. Flesh softening occurs rapidly during the first few weeks of air storage. Even when fruit are held at 0°C (32°F), approximately one-third to one-half of the remaining flesh firmness may be lost per month. Kiwifruit are highly sensitive to ethylene exposure during postharvest handling. Very low ethylene levels (5-10 ppb) will induce fruit softening.
