摘要： The commercial value of green raisins produced by the shade-air drying in Liang-fang was 2-3 times as high as that of yellow-brown raisins. This study systematically evaluated the effect of the temperature, humidity, and light of sun drying and shade-air drying on raisins. The sugar, acids, texture and color parament of raisins were compared with different drying conditions. The results indicated that shade-air drying can offer a dark and conducive light environment with the maximum temperature below 40 degrees C, and a lower humidity by segregating rainwater during the day as well. Then, the contents of acids of raisins in sun drying were lower compared with the shade-air drying and had a lower hardness and a* values of raisins. In summary, low light and ultraviolet intensity, suitable temperature and appropriate humidity environments were the basal and key factors for the formation of the green raisins. The present study not only revealed the crucial factors during shade-air drying in Liang-fang in Turpan, but also provided a scientific basis for improving the Liang-fang conditions and producing green raisins in other regions.
