摘要:

【目的】明确不同产区甜瓜果肉4种糖、2种维生素生物可及性差异,探讨土壤元素含量对该差异形成的影响,为甜瓜种植与消费者提供建议和饮食参考。【方法】以新疆吐鲁番、哈密、伊宁3个产区30份同品种甜瓜‘纳斯密’果肉及对应根际土壤为研究对象,通过高效液相色谱仪(HPLC)、电感耦合等离子体质谱仪(ICP-MS)等设备,分析甜瓜果肉样品中还原糖、果糖、葡萄糖、蔗糖、VB1、VB2及土壤样品中Fe、Mn、Zn等22种元素的含量,采用体外模拟消化检测相关营养素含量,计算营养素生物可及性;采用相关性分析、正交偏最小二乘回归PLS-DA、多元线性回归分析等统计分析方法,比较3个产区甜瓜果肉上述4种糖、2种维生素生物可及性差异,探讨土壤元素含量对该差异的影响。【结果】吐鲁番甜瓜果肉还原糖、果糖生物可及性分别为118.35%、113.02%,高于其他2个产区;哈密甜瓜果肉葡萄糖生物可及性高于其他2个产区,达195.27%;伊宁甜瓜果肉VB1和VB2含量及生物可及性高于其他2个产区。相关性分析结果表明,甜瓜果肉还原糖生物可及性与土壤中Cr、Ni、Sn、Sb、Ba、Tl、Pb 7种元素含量呈显著负相关,与B元素含量呈正相关;葡萄糖生物可及性与土壤Be、Al、Sr、Sn、Sb、Ba、Tl、Pb含量呈负相关,与Ti、V、Co、Cu、As、Se、Mo含量呈正相关;VB1生物可及性与土壤中Cr、Co、Ni、Cu、B、Sr含量呈正相关;VB2生物可及性与土壤中Al、Sr含量呈正相关。回归分析结果表明,土壤元素含量是影响甜瓜果肉中4种营养素生物可及性的重要因素,被影响程度大小依次是葡萄糖>VB1>还原糖>VB2,土壤Tl、V、Zn、Sn,Al、Zn、Sb,Tl、Fe、Mn、Zn,Al、V、Sr、Cd、Ba含量分别是影响甜瓜果肉葡萄糖、还原糖、VB1和VB2生物可及性的重要因子。【结论】可通过调控土壤中Tl、V、Zn、Sn,Al、Zn、Sb,Tl、Fe、Mn、Zn,Al、V、Sr、Cd、Ba等元素含量的方式,探索甜瓜果肉葡萄糖、还原糖、VB1和VB2生物可及性提升技术。

Abstract:

【Objective】This study aimed to clarify the differences in the bioaccessibility of four sugars and two vitamins in melon pulp from different producing areas, and to explore the influence of soil element content on the formation of this difference, so as to provide suggestions and dietary references for melon cultivation and consumers.【Method】Taking the pulp of 30 samples of the same variety of melon Nasimi and the corresponding rhizosphere soil from Turpan, Hami, Yining producing areas as the research object, the content of reducing sugar, fructose, glucose, sucrose, VB1, VB2 and 22 elements (such as Fe, Mn, and Zn) in soil samples were analyzed with test equipment, such as high-performance liquid chromatograph (HPLC) and inductively co,upled plasma mass spectrometer (ICP-MS). In vitro simulated digestion was used to detect the content of related nutrients, and the bioaccessibility of nutrients was calculated. Statistical analysis methods such as correlation analysis, orthogonal partial least squares regression PLS-DA, and multiple linear regression analysis were used to compare the differences in the bioaccessibility of the above four sugars and two vitamins in melon pulp from three producing areas, and to explore the influence of soil element content on this difference.【Result】The bioaccessibility of reducing sugar and fructose in Turpan melon pulp was 118.35% and 113.02%, respectively, which was higher than that in the other two producing areas. The bioaccessibility of glucose in Hami melon pulp was higher than that in the other two producing areas, reaching 195.27%. The content and bioaccessibility of VB1 and VB2 in Yining melon pulp were higher than those in the other two producing areas. The results of correlation analysis showed that the bioaccessibility of reducing sugar in melon pulp was significantly negatively correlated with the contents of seven elements (Cr, Ni, Sn, Sb, Ba, Tl, and Pb) in soil, and positively correlated with the content of B element. The bioaccessibility of glucose was negatively correlated with the content of Be, Al, Sr, Sn, Sb, Ba, Tl, and Pb in soil, and positively correlated with the content of Ti, V, Co, Cu, As, Se, and Mo. The bioaccessibility of VB1 was positively correlated with the content of Cr, Co, Ni, Cu, B, and Sr in soil. The bioaccessibility of VB2 was positively correlated with the content of Al and Sr in soil. Regression analysis results showed that soil element content was an important factor affecting the bioaccessibility of four nutrients in melon pulp, and the influence degree was in the order of glucose > VB1 > reducing sugar > VB2. The content of Tl, V, Zn, Sn; Al, Zn, Sb, Tl, Fe, Mn, Zn; Al, V, Sr, Cd, and Ba in soil were important factors affecting the bioaccessibility of glucose, reducing sugar, VB1, and VB2 in melon pulp.【Conclusion】The technology for improving the bioaccessibility of glucose, reducing sugar, VB1, and VB2 in melon pulp could be explored by regulating the content of elements, such as Tl, V, Zn, Sn; Al, Zn, Sb, Tl, Fe, Mn, Zn; Al, V, Sr, Cd, and Ba in soil.
