1.  To demonstrate in a semi-industrial scale plant the effectiveness of an innovative industrial process, able to obtain natural ingredients from discarded parts of citrus fruits (lemon, orange, grapefruit and tangerine), validating its economical and financial balance and its feasibility. This raw material is currently a residue of the citrus transformation industry and fresh citrus fruit packing, which could be valorised with the proposed process, in the respect of the existing environmental laws, with economic profit and generating a decisive waste reduction estimated around 80% of current volume.

2.  To disseminate among European citrus farmers, marketers and industries, relative associations and public bodies the concept that citrus industry scrap may be seen no longer as a polluting agro-industrial residue but as a valuable natural raw material. It will be demonstrated that new process offers to the sector improvement opportunities, adding value to the citrus products and valorising and minimizing industrial waste.

3.  To promote the use of healthy “clean label” ingredients in agro-food industry. The proposed process generates gelling agents not labelled with an “E-number”, usable as a natural ingredient in many food products, replacing alternative “E-number” additives. If raw material (citrus industry residues) comes from a biological certified growing and processing, a biological gelling agent can be obtained.

4.  To facilitate the preparation of low-calorie jams, jellies, juices and other food products (canned vegetables, bakery, pastry, beverages, etc.) and to disseminate this knowledge to regional, Spanish and European food industry. Gelling agents obtained in the proposed innovative process, unlike usual additives, react in the absence of sugar, allowing gelling light products. Specifically, a biological certificated new process should be able to provide the first gelling agent usable in biological lowcalorie
jams (product currently non-existent on market).

5.  To evaluate in pilot plant the capability to use this new process for the treatment of residues coming from other fruits and vegetable processing industries.

6.  To transfer project know-how to industry operators, in order to enable European citrus operators to apply the proposed process and technology at industrial scale, encouraging involved European industrial sectors and stakeholders to testing their residue in the plant.


1.  Enlargement and improvement of the pilot plant currently available in CTC to enable its utilization at semi-industrial scale for performing the proposed innovative process. A machine will be incorporated.

2.  Performing a test programme and conducting a detailed study about innovative process effectiveness, to characterize process parameters, to identify products specifications and to train CTC staff.

3.  Conducting a professional detailed cost-benefit analysis of the proposed process, with previous market study and basic industrial plant design, and a feasibility study.

4.  Creation and update, by web experts, of a new website, linked to the websites of the beneficiaries, to support the project communication and dissemination actions.

5.  Demonstration and disclosure regional programme and national/European programme, focused on targeted sectors, to outreach the advantages of the innovative process and to encourage particular
companies to test their own products or to promote demonstration sessions in the pilot plant. Specific initiatives will be directed to the biological certificated sector.

6.  Teaching training courses in CTC, focused on both technicians and operators of the targeted sectors and open to students, graduates and scientific and technical environment professionals.

7.  Starting up and maintaining throughout the project life and after its end an active dissemination and communication strategy, focused both on targeted companies, entities and public bodies and on general media. Project website linkage and promotion; ICT contacts; press-meetings; guided visits; press, radio and TV reviews and articles; publication of newsletters; placement of notice boards; distribution of brochures; layman’s report and a conference are scheduled.

8.  Publication of project results, proposed process parameters and expectations and obtained ingredients specifications in scientific and technical publications, and presentation of this information in congresses
and conferences.

9.  An efficient coordination, monitoring and evaluation system will be created to ensure an efficient project management, a continuous monitoring of the project's progress and a fulfilment in time of the
Commission requirements, including draw up an After-LIFE Communication Plan.

10.  External independent audit will verify the financial statements.

6.  At least 30 technicians, students, graduates and scientific and technical environment professionals participate in the 3 calls of the scheduled training course.

7.  A powerful and dynamic project website will be created, linked with the beneficiaries's webs and, at least, 5 relevant related websites, updated monthly along project duration and quarterly along a minimum of 5 years after the end of the project, and used as the basic project communication tool. At least, 10000 visits to the project website are expected.

  1. An intensive test programme and a detailed study has been done, as planned in the proposal, using a semi-industrial plant of the proposed process.
  2. CTC pilot plant was enlarged in order to demonstrate de proposed process for the transformation of citrus residues into a valuable by-product, with the incorporation of a high-speed knife cutter.
  3. Throughout the test programme, 6.500 kg residues have been processed and 13 different foodstuffs have been produced (27 samples).
  4. The transformation of citrus residues into a citrus puree for substituting commercial pectins is highly profitable. The application of the new ingredient as natural substitute for pectin generates a new line of industrialization. However, the location of the processing plant is a fundamental factor that may minimise the cost for residues transportation.
  5. Great efforts have been done in order to spread the project know-how to industry operators and foster the replicability of the transformation process. 92 regional companies were contacted: 48 of them process lemon, 53 also process other citrus and non-citrus fruits and 43 produce jams, jellies and/or other foodstuffs. There were also contacted national and international companies: 58 of them process citrus fruits and 61 produce jams, jellies and/or other foodstuffs. After reaching the objectives of contact with 50 regional and 60 national/international companies, beneficiaries continued informing entities aiming to improve the replicability and transferability potential of the project.
  6. 27 tests with 16 different regional companies, 4 tests with 2 national (Spanish) companies of citrus sector and 4 tests with 3 national (Spanish) companies of foodstruffs were developed at the demonstration plant in CTC.
  7. 40 people participated in the courses organized (three editions).
  8. Regarding the dissemination activities, every task planned in the proposal has been carried out. Particularly, the website has reached 10.971 visits from 82 different countries. The conference was successfully organised and had 376 attendees from 17 different countries; moreover, beneficiaries participated in 7 national and international related congresses, while the objective was to participate in 2 congresses. The appearance of the project in media have been also satisfactory, being very helpful for that the two press-meetings and the two guided visits for journalists. The LifeCitrus project appeared in 22 in press, radio and TV. Six semi-annual reports (newsletters) were published in two languages (English and Spanish) and Layman´s report is available with results. A technical article titled “Healthier food through the use of a new natural ingredient obtained during the recovery of citrus by-products” was published in ‘Alimentaria’ magazine (Alimentaria #496).
  9. In regard to networking activities with other project, an intensive work has also been done. The objective of networking with 3 related projects has been achieved by far. Beneficiaries have developed networking activities with 13 Life projects and 2 Erasmus+ projects, among others.
  10. The project has been disseminated continuously to all interested people and the demonstration plant of the process has been open to visits upon request. In the project lifetime, the plant has been visited by 475 people in a total of 38 visits. Once the project is finished, communication actions will be promoted, and the pilot plant will be available for new tests.
