520	3		_aThe yacon tuber has gained interest due its health-promoting components, such as high amounts of fructooligosaccharides (FOS) and phenolic compounds with strong antioxidant properties. However, the high water content and the soft, delicate internal tissues render it highly perishable, leading to significant losses during postharvest handling. The packaging and storage temperatures, two important factors in maintaining quality when storing fresh yacon tubers, were studied. The results showed that modified atmosphere packaging (MAP) combined with low temperature (10ºC) had positive effects on the visual quality of yacon. Weight loss and shriveling were reduced in MAP compared to the unpacked yacon under room and 10ºC storage temperatures. The use of MAP under room temperature for an extended storage period was limited by the development of disease and the occurrence of root sprouts and surface cracks in yacon, which reduced its visual quality. FOS hydrolysis by fructan exohydrolase occurred during storage, leading to higher amounts of fructose, glucose, and sucrose. The use of MAP regardless of storage temperature delayed the onset of rapid FOS decline. The total phenolic contents in the range of 4.84-5.98 mg Gallic acid equivalent per gram dry sample and antioxidant activity of yacon did not decrease relative to its initial content. Yacon could be stored at 10ºC in conjunction with MAP to maintain quality and extend the shelf life of fresh yacon tubers.
