Study on influence of ice-temperature storage on yacon quality
The changes of physiological and storage quality of yacon at cool storage (4℃)and ice-temperature storage(0℃) conditions were investigated in this paper.The results showed that the hardness and the contents of fructo-oligosaccharide and moisture were decreased more significantly by cold acclimation combined with icetemperature storage than ordinary cool storage.On the 90th day of storage,it showed 1974.59g by hardness,70.44mg/g by fructo-oligosaccharide content,84.93％ by water content,27.64mg/g by reducing sugar content and 51.38μg/g by ascorbic acid content.However,the result by cool storage was 1862.11 g,67.28mg/g,84.21％,25.53mg/g and 50.25μg/g in turns.As a result,it could be concluded that cold acclimation combined with icetemperature storage was better for the quality of yacon than ice-temperature storage alone.
