Abstract:
Xinjiang is far from the mainland, the deterioration of fresh apricots is accelerated during transportation and the shelf-life is short. In this study, the Xinjiang ‘Saimaiti apricots’ were used as experimental materials to simulate the cold chain transportation process of fresh apricots after harvest. The effects of cold chain transportation at near freezing temperature(-1.6~-1.1 ℃) on the qualities of apricot fruits during shelf-life were studied with 1~2 ℃and 4~6 ℃ as control. The results showed that the shelf-life of apricot fruits stored for 42 days near freezing temperature could reach to 6 days at 17~18 ℃ after transported by cold chain at freezing temperature, and the decline of hardness, soluble solid, titratable acid, ascorbic acid contents and color changes were delayed. On the 6 th day of shelf-life, the hardness was 5.04 N and commodity rate was 62.22%. Compared with 1~2 ℃ and 4~6 ℃ cold chain transportation groups, the near freezing temperature group maintained the best sensory qualities and the longest shelf-life.
