Research Project: Characterization and Manipulation of the Color of Fresh Citrus Fruit Especially Regarding to Improve Fruit Appearance under Hlb Disease

Location: Citrus and Other Subtropical Products Research

Project Number: 6034-41430-006-02
Project Type: Specific Cooperative Agreement

Start Date: Jun 01, 2014
End Date: Sep 30, 2016

Objective:
1. Characterize color development of orange under HLB disease. 2. Investigate the efficacy of ClO2 on reducing spoilage and improving safety and shelf-life in fresh produce; and 3. Determine natural and food grade dyes which are compatible l with fruit peel and citrus coatings.

Approach:
1) Analyze color components and related metabolic activities in fruit which influence peel color and in flavedo; 2) observe changes of color and decay in the presence of added sanitizers such as chlorine dioxide in fruit under degreening process; 3) determine chemical and biological features of natural dyes and develop formulations for citrus dyes to apply to fresh citrus fruit.
