Postharvest of Fruit and Vegetables

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

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...

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

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...

1-MCP Inhibits Kiwifruit Softening During Storage

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),...

A Comparative Study of Composition and Postharvest Performance of Organically and Conventionally Grown Kiwifruits

Postharvest performance of organic and conventional ‘Hayward’ kiwifruits grown on the same farm in Marysville, California, and harvested at the same maturity stage were compared in this study. Quality parameters monitored included morphological (shape index) and physical (peel...

Is Dry Matter a Reliable Quality Index for 'Hayward' Kiwifruit

Dry matter (DM) measurement at harvest is being proposed as a quality index for ‘Hayward’ kiwifruit because it includes both soluble solids (mainly sugars) and insoluble solids (largely structural carbohydrates and starch). From two seasons’ data, in-store consumer acceptance was...

Evaluation of a Non-Destructive Dry Matter Sensor for Kiwifruit

In this work we studied the relationship between kiwifruit dry matter (DW) measured using the destructive method with a fruit dehydrator (Nesco/American Harvest®, Wisconsin, USA) and a non-destructive Kiwi meter sensor (Turoni Inc., Forli, Italy). This was an approach to develop a reliable non-...

Ozone-induced Kiwifruit Ripening Delay is Mediated by Ethylene Biosynthesis Inhibition and Cell Wall Dismantling Regulation

Ozone treatments are used to preserve quality during cold storage of commercially important fruitsdue to its ethylene oxidizing capacity and its antimicrobial attributes. To address whether or not ozonealso modulates ripening by directly affecting fruit physiology, kiwifruit (Actinidia deliciosa cv...

Storage of Kiwano (Horned Melon) fruits

The African horned melon (Cucumis metuliferus), also known as horned cucumber, kiwano and melano) is a cucurbit fruit with an yellow-orange exterior with thick blunt spines and a green, gelatinous pulp embedding the many seeds. It is endemic to semi-arid Africa (Bruecher, 1977; National Research...

Postharvest Respiration, Ethylene Production, and Compositional Changes of Chinese Jujube Fruits

Production rates of CO2 and C2H4 by fruits of jujube (Zizyphus jujuba Lam.), picked at the whitish-green stage and held at 20ºC for 15 days, followed a nonclimacteric pattern. Skin color changed from whitish-green to reddish-brown with fruit maturation. Relative to most other fresh fruits,...

Harvest and Postharvest Handling of Chinese Date

Jujube, or Chinese date, is a deciduous fruit tree of tropical and subtropical origin, now grown primarily in home gardens in California and Florida. Among problems that have limited development of jujube as a commercial crop in California are several factors related to harvesting and...
