Project title : Use of Electronic Nose to Evaluate Aroma Quality of ‘ Gala ’ , ‘ Fuji ’ , ‘ Delicious ’ and ‘ Granny

چکیده
Objectives: The goals of this 4-year project were extended gradually from developing alternative apple coatings to three additional goals: (1) Evaluate flavor of major apple varieties using GC and electronic nose during CA storage and simulated marketing for documentation of changes due to storage time, temperature, atmosphere, and 1-MCP pre-treatment (to determine flavor life as opposed to shelf life); (2) Develop fresh-cut apple technologies, including anti-browning, coating and pre-treatment before cutting; and (3) Continually develop and evaluate alternative apple coatings for major apple varieties.

Consumer evaluation and quality measurement of fresh-cut slices of ‘Fuji,’ ‘Golden Delicious,’ ‘GoldRush,’ and ‘Granny Smith’ apples
We compared the eating quality of a new apple cultivar, ‘GoldRush,’ with ‘Golden Delicious’ (one of its parents), ‘Fuji,’ and ‘Granny Smith’ (the latter two often used for fresh-cut apple slices). We also compared a commercial with an in-house processing treatment, NatureSeal for apples and Produce Quality and Safety Laboratory (PQSL), respectively. Intact apples that had been stored for about ...

Apple fruit color is determined by the amount of pigments in its peel which is directly affected by sunlight. A method for improving apple fruit color is bagging. In present study, the effect of bagging and its optimum removing time was investigated on the amount of peel pigments and other fruit quantitative and qualitative characteristics for Fuji and Granny Smith apples. The experimental tre...
متن کاملDevelopment of a Susceptibility Index of Apple Cultivars for Codling Moth, Cydia pomonella (L.) (Lepidoptera: Tortricidae) Oviposition
Codling moth (CM), Cydia pomonella (L.) (Lepidoptera: Tortricidae) is a major fruit feeding pest of apples. Understanding susceptibility differences of various apple cultivars to CM oviposition is an important step in developing resistant varieties as well as monitoring and management strategies for this pest in apple orchards planted with mixed-cultivars. In this context, oviposition preferenc...
متن کاملMonitoring the aroma production during wine-must fermentation with an electronic nose.
This work discusses the feasibility of using the electronic nose for the on-line and real-time monitoring of the production of a complex aroma profile during a bioconversion process. As a case study, the formation of the muscatel aroma during the wine-must fermentation was selected. During wine-must fermentation, aroma compounds responsible for the organoleptic character are produced in the ppm...
