Book Effects Of 1 Methylcyclopropene On Antioxidant Status And External Carbon Dioxide Injury Of  Empire  Apples

This book was released on 2009 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Extensive studies have suggested that apple consumption is associated with prevention of chronic diseases such as cardiovascular disease, certain cancers, diabetes and asthma as apple is a rich source of phytochemicals with strong antioxidant and antiproliferative activity. 1-Methylcyclopropene (1-MCP), an ethylene inhibitor has been extensively used by the apple industry to maintain quality of various apple cultivars. In New York, use of 1-MCP has been especially high because it maintains firmness throughout the marketing chain. The use of 1-MCP has raised two issues that are addressed in this thesis. The first is the relatively small amount of information about the effects of 1-MCP on nutritional quality of apple fruit. The second is that 1MCP appears to increase susceptibility of certain cultivars to physiological injuries, and in 'Empire', external CO2 injury. The effect of 1-MCP treatment on the phytochemical concentrations and activity and ascorbic acid concentrations of 'Empire' apple as affected by air and controlled atmosphere (CA) storage was investigated. Fruit were stored in air for up to 5 months, and in CA in 2 and 3 kPa O2 (2% CO2) at 0.5 and 2.2 oC for 4.5 and 9 months. Ripening was delayed by 1-MCP treatment in both air and CA storage as indicated by internal ethylene concentrations and flesh firmness. Overall, total phenolic, flavonoid and anthocyanin concentrations as well as antioxidant activity are relatively stable during air and CA storage. In CA, interactions among oxygen level, temperature and storage duration were detected but no consistent trends were observed. The only effects of 1-MCP on flavonoid or anthocyanin concentrations of fruit stored in CA were found in the flesh. Flavonoid concentrations were higher in the flesh of 1-MCP treated than untreated fruit kept in 2 kPa O2 while anthocyanin concentrations only measured in the peel were not affected. Phenolic concentrations were higher in the peel while lower in the flesh of 1-MCP treated fruit compared to the control fruit stored in air. There were no correlations found between total phenolics and antioxidant activity. Ascorbic acid concentrations declined in both peel and flesh tissues of untreated and 1-MCP treated fruit stored in air. In CA, the change was affected by several storage parameters and there were inconsistent pattern in the decline of ascorbic acid concentrations in CA-stored fruit. The effects of CO2 partial pressure, the timing of elevated CO2 exposure, delays between harvest and exposure to elevated CO2, DPA concentration, and the timing of DPA treatment after exposure of fruit to 1-MCP on the susceptibility of untreated and 1-MCP-treated 'Empire' apple fruit to external CO2 injury have also been investigated. 1-MCP-treated fruit were more susceptible to external CO2 injury than untreated fruit when stored in 5 kPa, but not 1 kPa CO2 (in 2 kPa O2). 1-MCP did not increase the period of highest susceptibility to injury during CA storage. The greatest sensitivity to injury occurred 0-3 weeks after harvest. Sensitivity to injury decreased when untreated fruit were kept in air for up to 14 days before exposure to 5 kPa CO2, but not for 1-MCP-treated fruit. DPA treatment prevented development of CO2 injury even at a level as low as 250 [MICRO SIGN]L L[-]1. DPA treatment could be delayed for 4 days after 1-MCP treatment while fruit were exposed to 5 kPa CO2 in air without injury development.

Book Fruit and Vegetables

Download or read book Fruit and Vegetables written by Anthony Keith Thompson and published by John Wiley & Sons. This book was released on 2008-04-15 with total page 489 pages. Available in PDF, EPUB and Kindle. Book excerpt: The second edition of this very well-received book, which in itsfirst edition was entitled Postharvest Technology of Fruits andVegetables, has been welcomed by the community of postharvestphysiologists and technologists who found the first edition of suchgreat use. The book covers, in comprehensive detail, postharvestphysiology as it applies to postharvest quality, technologyrelating to maturity determination, harvesting, packaging,postharvest treatments, controlled atmosphere storage, ripening andtransportation on a very wide international range of fruits andvegetables. The new edition of this definitive work, which contains manyfull colour photographs, provides key practical andcommercially-oriented information of great use in helping to ensurethat fruit and vegetables reach the retailer in optimum condition,with the minimum of loss and spoilage. Fruits and vegetables, 2nd edition is essential readingforfruit and vegetable technologists, food scientists and foodtechnologists, agricultural scientists, commercial growers,shippers and warehousing operatives and personnel within packagingcompanies. Researchers and upper level students in food science,food technology, plant and agricultural sciences will find a greatdeal of use within this landmark book. All libraries in researchestablishments and universities where these subjects are studiedand taught should have copies readily available for users. A. K. Thompson was formerly Professor and head of PostharvestTechnology, Silsoe College, UK.

Book Starch Metabolism In Apple Fruit And Its Relationship With Maturation And Ripening

Download or read book Starch Metabolism In Apple Fruit And Its Relationship With Maturation And Ripening written by Franziska Clara Doerflinger and published by . This book was released on 2015 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: Harvest timing of apples, an important factor determining fruit quality after storage, is often based on maturity assessments that include the starch pattern iodine (SPI) test. The SPI test provides a visual indicator of starch degradation in the equatorial region of the fruit. SPI and starch concentrations in apple cultivars, and the effects of factors such as aminoethoxyvinylglycine (AVG) and 1-methylcyclopropene (1-MCP), have been investigated. SPI values increased as starch concentrations declined in 'Gala, 'Honeycrisp', 'McIntosh', and 'Empire' apples during maturation. The two factors have a curvilinear relationship for all cultivars. Declines in percentage of amylose were found to be linear and cultivar dependent. Computer-based image analysis of SPI-based staining revealed a wide range of values, and a linear correlation was found between SPI value and percentage stained area. Starch concentrations in stem-end tissues were lower than in equatorial and calyx-end tissues of 'Empire' and 'Gala' apples. AVG and 1-MCP applied preharvest to inhibit ethylene production and perception, respectively, had cultivar as well as application timing-dependent effects on maturation. Effects of these treatments on starch degradation were limited in both 'McIntosh' and 'Empire' fruit. Weak correlations were found for 'Empire' apples between harvest indices and differences in absorbance (IAD) readings, which reflect chlorophyll concentrations in the skin. However, preharvest treatment of fruit with AVG and 1-MCP altered the relationships between IAD and other harvest indices, especially the internal ethylene concentration (IEC). 'Empire' apples are susceptible to firm flesh browning when stored at temperatures close to 0 °C, or after treatment with postharvest 1-MCP. This storage disorder causes major losses for the apple industry every year and no storage regime has been found so far to alleviate the problem. A full economic analysis indicated that there is an economic tradeoff between harvest date, occurrence of flesh browning, and likely net profits. Overall maturity assessment at harvest could be used as an indicator for storage disorders and/or storage length if factors such as differences in fruit maturation between cultivars and within the fruit are better understood.
