Description
Relationships between pre and post-harvest quality all along the value chain, from the field to the can, including:
- The impact of water shortage on quality traits of tomato purees (color, biochemical composition and viscosity) (in relation to Agronomist PSH team of INRA Avignon, France)
- The identification of the volatile compounds related to quality change during the process by dynamic headspace technics.
- The impact of the processing (hot or cold break on lycopene bio-accessibility, color and viscosity)
- The infrared model for the prediction of tomato composition and quality attribute in manufactured product. Transfer of the NIR technic to the industry (in relation with Sylvie BUREAU – INRA SQPOV Avignon, France)
