摘要: 为探索不同采收成熟度水晶葡萄贮藏后的商品价值,以3个不同时期采摘的水晶葡萄为试验对象,采用PE20保鲜袋为包装材料,在温度(1.0±0.3)℃、相对湿度(90±5)%条件下贮藏。结果表明,贮藏到60 d时,七成熟果实腐烂率(14.42%)、脱粒率(20.26%)、褐变率(25.16%)、可溶性固形物含量(12.07%)均低于八、九成熟果实,而硬度(270.19 g)高于八、九成熟果实,含水率在整个贮藏期各成熟度之间无差异;八成熟果实腐烂率(20.89%)、脱粒率(25.06%)、褐变率(33.88%)均比九成熟果实低,维生素C含量(0.080 mg/g)高于九成熟果实。综上,七成熟果实耐贮性虽优于八、九成熟果实,但七成熟果实可溶性固形物含量较低,导致口感不佳,九成熟果实维生素C含量低于八成熟果实,且腐烂、褐变、脱粒严重,商品价值较八成熟果实低。综上,水晶葡萄在八成熟时采收,更有利于提高贮藏后的商品性。

Abstract: In order to explore the commercial value of crystal grapes with different harvest maturity after storage,the crystal grapes picked in three different periods were taken as experimental objects,and PE20 fresh-keeping bags were used as packaging materials stored at (1.0 ±0.3)℃ and relative humidity of (90±5) %.The results showed that stored for 60 days,the 70% maturity fruit’s rot rate(14.42%) ,threshing rate(20.26%) ,browning rate(25.16%) ,soluble solid content(12.07%) were lower than the 80% and 90% maturity. The hardness(270.19 g) was higher than the 80% and 90% maturity,and the water con tent did not differ among the maturity during the whole storage period. The 80% maturity fruit’s rot rate (20.89%) ,threshing rate( 25.06%) ,browning rate( 33.88%) were lower than those of the 90% matu rity,and vitamin C content(0.080 mg/g) was higher than 90% maturity.In summary,the 70% maturity fruit’s storability was better than the 80% and 90% maturity,but its soluble solid content was lower,re sulting in poor taste,and the 90% maturity fruit’s vitamin C content was lower than the 80% maturity.In addition,the 90% maturity fruit’s rot,browning and threshing were serious,and the commodity value was lower than that of the 80% maturity.Therefore,the comprehensive comparison showed that the crystal grape should be harvested at the 80% maturity,which would be more conducive to the commodity value after storage.
