In addition, sulphur dioxide has strong antimicrobial capacity and preserves against microbial spoilage. "The SO2SAY project will develop a strategy to replace the application of sulphur dioxide or its salts for almost all food products" explains coordinator Hauke Hilz. "An important aspect for food applications is the preservation of the sensory quality and shelf-life of the SO2-free products."
EU-funded project starts research on replacement of sulfites in food
Nine partners from four European countries and Israel start their work on SO2SAY, a three year EU-funded project with a total budget of 4.5 mio €, thereof 3 mio € funding, with a kick off meeting in Bremerhaven, Germany. The project, coordinated by ttz Bremerhaven, will combine research on innovative SO2 replacing agents, mild processing steps and packaging technologies. ttz Bremerhaven (DE), Campden BRI (UK), Wageningen University (NL), University of Bonn (DE), Fundacion Leia (ES), Gemüse Meyer (DE), Biurko Gorri (ES), Ekolo (ES) and Frutarom (IL) defined to increase food quality, to reduce health risks for consumers as well as to increase the competitiveness of European SMEs in the food and drink industry on the global market as their main strategic objectives.
Sulphur dioxide (SO2) is traditionally used as antioxidant and preservative in fruit and vegetable products, dried fruits, snack products and wine. The main advantage of SO2 is the combination of antioxidative activity with its ability to inhibit polyphenol oxidase, which is catalysing browning of food products. Furthermore, sulphur dioxide acts as food preservative preventing microbial growth. However, SO2 and sulphites strongly reduce vitamin B1 uptake. Reduced uptake of this vitamin can lead to several health problems such as chronic headache and disturbance of the memory. Food is the main source for the uptake of sulphur dioxide.
A special risk group is the group of asthma patients. Sulphites are promoting attacks of asthma. For these patients an intake of less than 10 mg sulphite might be enough to provoke an asthma attack.
"Considering these facts, the application of SO2 in food products has to be avoided by novel processing technologies or replaced by different, healthier additives", knows Hauke Hilz. "This will promote Food Quality and Safety as well as consumer's Quality of Life".
Three approaches are followed to finally replace SO2 and sulphites in food:a. Reduction of oxygen contact of the food producs e.g. by modified atmosphere packaging or by edible coatings for fruits and vegetables,

The Laser Zentrum Hannover e.V. (LZH) will present how laser-based technologies can contribute to the laboratory of the future at the LABVOLUTION in Hannover in Hall 9, Stand E67/09, from October 6th to 8th, 2015. As a part of the model lab smartLAB, the LZH is showing how additive manufacturing, better known as 3-D printing, can make experimental setups more flexible.
Twelve partners from science and industry are presenting an intelligent and innovative model lab at the special display smartLAB. A part of this intelligent...
Before embarking on a transcontinental journey, jet airplanes fill up with tens of thousands of gallons of fuel. In the event of a crash, such large quantities of fuel increase the severity of an explosion upon impact.
Researchers at Caltech and JPL have discovered a polymeric fuel additive that can reduce the intensity of postimpact explosions that occur during accidents and...
