02 Nov 2016 --- Finnish researchers may have found a new use for colorful autumn leaves that fall and dry on the ground at this time of year - by extracting the natural compounds and using them as food coloring, preservatives and nutritional supplements. Nordic research and technology company, VTT Technical Research Centre of Finland, says that natural pigments and useful raw material from the autumn leaves can be transformed into use for the food industry as well as feed, cosmetics and textiles.
