Final Report Summary - SAFEWASTES (Evaluating physiological and environmental consequences of using organic wastes after technological processing in diets for livestock and humans)
The SAFEWASTES project grouped academic staff and food industry small and medium-sized enterprises (SMEs) with expertise in phytochemistry, microbiology, nutrition, veterinary medicine, feed technology and manufacturing, as well as in environmental protection, to develop innovative biotechnological processes for food and herb wastes from the plant-based industry to recover valuable compounds. One key project aim was to develop organic feed additives to replace in-feed antibiotics, which use was banned in the European Union.
SAFEWASTES would help food manufacturers to employ scientific approaches to meet consumer demands for safer, higher quality food. Animal welfare was one of the key issues within the politics of the EU which in addition should lead to better food products. The organic waste material from industry showed already high potentials for use as new, natural and functional products that would improve the quality of life of animals and of the humans, as well.
Prerequisite standard operating procedures (SOPs) were developed for the process technology, namely for the production of extracts of organic waste material - solvents such as water, ethanol and heptane, for the bioassay guided fractionation and for several in-vitro tests.
In vitro test systems were developed and validated for testing the following:
- anti-parasitic activity;
- anti-pathogenic activity;
- the influence of organic wastes in caecal bacteria growth of pigs with a colon simulation technique;
- anti-microbial activity, as well as anti-oxidative activity.
Contrary to what was anticipated, waste materials exhibited high antioxidant activity. The results strongly depended on the starting material, however even after the extraction of oil and phenolic compounds (OPCs). Based on the assumptions of better health and performance the feed additives mango, larch, pumpkin and thyme could be beneficial ingredients for the feed of pigs and poultry. Small percentages of 2.5 to 10.0 % of the additives should be added for those positive effects. The most interesting feeds to add these additives to were those for sows, broilers and parent stock.
