The approach MARKET RAW MATERIAL FOOD PROCESSING BY-PRODUCTS Characterization & Preservation Pre-treatment & Ingredient recovery New foods formulation (innovative and sustainable processes/technologies) New feeds (for aquaculture) Assessment of products & processes/technologies Identification of new market opportunities Knowledge transfer & exploitation
Expected Impacts WP 1: Project Management & Coordination WP 5: Assessment of innovative industrial protocols WP2: Characterization and stabilization of by-products/wastes from EU industries WP3: I ngredients for new foods: pre-treatment of by-products, recovery & production of natural molecules WP4: Application and Validation of products for food and feed applications Increased industrial sustainability (integration of food byproducts producers and exploiters) Consumers benefits : healthy safety and high quality foods EU-India research cooperation : common technical standards, protocols, regulations & policies New EU-India market opportunities: NAMASTEs industrial partners and the industrial platform would be the first nucleus IndustrialPartners WP 7: Innovation and Dissemination WP 6: EU-INDIA Integration
Citrus by-products valorization Characterization
World citrus production The Mediterranean area is one of the biggest producers, after Brazil and together with China and USA. Source: http:// www.unctad.org/infocomm/anglais/orange/market.htm (Proportion of average annual production data for 2000-2004)

Citrus by-products generation About 1.200 thousands of tonnes of citrus processing by-products are produced yearly in the Mediterranean area. Of the total citrus for processing, nearly 85 percent is forecast to be oranges.
Actual valorization routes <ul><li>The main actual destiny for the main volume of citrus by-products is cattle feeding. </li></ul><ul><li>The yield of feed production is about 0.166 Tm of feed/Tm of fresh by-product. </li></ul><ul><li>High operational costs (mainly drying costs). </li></ul><ul><li>Low profit but avoids higher costs of disposal. </li></ul>Very demand depending.
<ul><li>Production of D-limonene. </li></ul><ul><li>Bioethanol production. </li></ul><ul><li>Pectin extraction in Europe: can be considered residual. </li></ul>Actual valorization routes
Analytical characterisation <ul><li>Citrus by-products have been characterised for: </li></ul><ul><li>Physical characteristics: fractions, particle size, density. </li></ul><ul><li>Proximate analysis: protein, fat, ash, sugars, TDF and total phenols. Polysaccharides (bran). Fatty acid composition. </li></ul><ul><li>Specific bioactive compounds. </li></ul><ul><li>Microbiological quality. </li></ul><ul><li>Contaminants: heavy metals, pesticides and mycotoxins. </li></ul>

<ul><li>Content in specific bioactive compounds confirms that the citrus by-products may be an interesting source of bioactives. </li></ul>Analysis of Specific compounds
<ul><li>By-products have a high water content. </li></ul><ul><li>Pectins and polyphenols are fast degraded by enzymatic reactions. </li></ul><ul><li>Microbial environmental contamination. </li></ul><ul><li>Stabilization and preservation of the raw material. </li></ul><ul><li>Drying costs limit the rentability of most valorization alternatives. </li></ul>Challenges
Citrus by-products Stabilization and extraction of valuable compounds
Objectives <ul><li>Finding a suitable stabilisation procedure. </li></ul><ul><li>Eliminating undesirable compounds. </li></ul><ul><li>Obtaining good quality and safe food ingredients. </li></ul>
Mayor achievements <ul><li>Stabilized material has been obtained by different alternative methods. </li></ul><ul><li>Several citrus peel extracts have been obtained and are being characterized. </li></ul><ul><li>A protocol for obtaining a citrus fiber is being defined. </li></ul>
Proposed valorizations <ul><li>Food and feed ingredients (WP3) </li></ul><ul><li>New Food Products and Feed formulation and production (WP4) </li></ul>
Future activities Definition of protocols for the elaboration of new food products. Design of preventative and control measures to guarantee the quality and safety of the defined processes.
