摘要:

【目的】探究采前喷施糖醇钙对库买提杏果实品质及挥发性物质的影响。【方法】以库买提杏为试材,采前喷施稀释800、1 200和1 600倍糖醇钙溶液,测定成熟期的果实品质,同时利用顶空固相微萃取-气相色谱-质谱(headspace solid phase microextraction-gas chromatography-mass spectrometry)联用技术,测定成熟期库买提杏果实的挥发性物质。【结果】采前喷施糖醇钙均能提高杏果实品质,其中KMT-800处理最为显著,单果重、果实硬度、可溶性固形物、VC含量和可滴定酸含量较CK增加了8.50%、64.13%、31.05%、61.03%和86.57%。不同浓度的糖醇钙处理库买提杏果实的挥发性物质总含量均显著高于CK,其中KMT-800处理果实的挥发性物质含量最高,为(220.89±26.88) μg/g,较CK增加了48%,其次是KMT-1200处理、KMT-1600处理,果实挥发性物质总含量较CK分别增加了39%、25%。筛选出59种关键香气物质,其中萜类、杂环化合物、醇类、酚类和酮类化合物含量与CK处理存在显著差异。【结论】KMT-800糖醇钙处理在提高库买提杏果实品质及挥发性物质效果最佳。

Abstract:

【Objective】 To investigate the effects of calcium sugar alcohol spray before harvest on the quality and volatile substances of apricot fruit in Kumaiti. 【Methods】 Using Kumaiti as the test material, the fruit quality at maturity was determined by spraying 800, 1,200, 1,600 times diluted calcium sugar alcohol calcium solution before harvest. At the same time, headspace solid phase microextractivity-gas chromatography-mass spectrometry was used to determine the volatile compounds of apricot fruit at maturity stage. 【Results】 The quality of apricot fruit was improved by applying sugar alcohol calcium before harvest, among which KMT-800 treatment was the most significant. The single fruit weight, fruit hardness, soluble solids, vitamin C content and titrable acid content were increased by 8.50%, 64.13%, 31.05%, 61.03% and 86.57% compared with CK. The total content of volatile substances in Kumaiti fruit treated with different concentrations of calcium sugar alcohol was significantly higher than CK. The content of volatile substances in fruits treated with KMT-800 was the highest, which was (220.89±26.88) μg/g, an increase of 48% compared with CK. The total content of volatile substances in fruits of KMT-1,200 treatment and KMT-1,600 treatment increased by 39% and 25%, respectively.A total of 59 key aroma substances were screened, the contents of terpenoids, heterocyclic compounds, alcohols, phenols and ketones were significantly different from those of CK treatment. 【Conclusion】 The results show that the treatment of KMT-800 sugar alcohol calcium has the best effect on improving the quality and volatile substances of apricot fruit.
