Solar food processing is an innovative and multi-faceted technique capable of addressing various problems faced by people in the developing world. The implementation of technologies for food processing and conservation using solar energy can indirectly help to reduce poverty, improve health conditions, create sustainable local economic opportunities, and limit environmental damage by promoting the use of clean and renewable energy sources. This project targets developing countries with a high solar radiation potential, in particular those countries in need of unique and sustainable development assistance and ideas that relate to solar food products.

The project aims to extend and develop efficient methods of solar food processing for the following activities:

• Conservation of fruits and vegetables (See Canning and Drying.)
• Drying crops
• Roasting different kind of nuts
• Pasteurising juice, fruits and vegetables
• Baking bread and cake. (See Solar restaurants and bakeries.)

Objectives:

• Improvement in the quality of food;
• Creation of local jobs and income; (See Income generation.)
• Demonstrating environmental benefits (with high potential for CO2 emissions reduction)
• Involvement of local personnel and local resources
• Creation of a new market and encouragement of economic competition in this field.

Recent news and developments

• January 2013: The Solar Food Processing Network meets to discuss international standards - The Solar Food Processing Network (SFPN) held a regional workshop in January 2013 at the Muni Seva Ashram in Goraj, Vadodara, Gujarat, India. This gathering was a follow-up to the 2009 AFPN conference held in Indore, India in 2010. Workshop participants heard from food marketing and technology experts. Conference organizers, Deepak Gadhia and Rolf Behringer held discussions on local and international marketing, village industries, packaging, policy interventions, R&D, and effective monitoring and evaluation of projects. Attendees discussed the formation of an international solar food standard and shared their own practical experiences using solar technology for food processing. Visit the Solar Food Processing Network to see a muscial video of the event and videos of solar food processing projects in Burkina Faso.

• Effect of pressure and solar cooking on phytic acid and polyphenal content of cowpeas (Abstract: Both pressure cooking and solar cooking significantly reduced the phytic acid and polyphenol content of cowpea cultivars. A significantly greater reduction in the content of both these antinutrients was noticed during pressure and solar cooking of soaked cowpeas compared to unsoaked seeds. The percentage reduction increased when the soaked cowpeas were dehulled and then cooked by both pressure and solar cooking. The results of the study reveal that solar cooking was more effective than pressure cooking in reducing the concentrations of phytic acid and polyphenols in cowpeas. The cumulative effect of soaking and dehulling, followed by solar cooking, was the removal of most of the polyphenols (88-94 per cent). Such practices should be encouraged at the home level for the preparation of cowpea seeds.)
