Improving the Storage of Sugar Beet by Polymeric Coverage Containing Phase Change Material

The aim of this experiment was to study the sugar and weight losses and non-sugar impurities of sugar beet during the storage by coverage containing phase change material (PCM). The combination of six coverage types and two storage intervals of 20 and 40 days was arranged in a greenhouse with temperature ranging from 8.5 to 24.5 °C and relative humidity between 47 and 80 %, and paraffin was used as PCM. The polyethylene coverages containing 0, 7 and 14 % paraffin with and without lamination were utilized. The results showed that during the course of 40 days, weight and sugar losses of sugar beet in samples without coverage were 10 and 6.5 times higher than the sample with coverage containing 14 % paraffin ( P
