摘要:

为探讨喷雾干燥温度对牦牛乳粉溶解特性的影响,分析了在进风温度(出口温度)分别为130(56)、150 (64)、170(73)、190(81)、210(90)℃条件下喷雾干燥牦牛乳粉样品的溶解特性参数,并通过相关性分析对其进行聚类分析。结果表明:喷雾干燥温度对牦牛乳粉的溶解特具有显著影响(P<0.05),170(73)℃下喷雾干燥牦牛乳粉样品具有较高的水合能力、堆积密度、溶解度,较小的休止角和分散时间,具有较好的溶解特性,优于在其他温度下干燥牦牛乳粉的溶解特性;牦牛乳粉溶解特性参数间具有较好的相关性,聚类分析可实现对不同喷雾干燥温度条件下牦牛乳粉溶解特性的区分,为对喷雾干燥温度的评价提供参考。

Abstract:

In order to explore the effect of spray drying temperature on the solubility of yak milk powder, solubility
characteristics of yak milk powder produced at different inlet/outlet temperatures (130/56, 150/64, 170/73, 190/81, and
210/90 ℃) were measured and analyzed through correlation and cluster analysis. The results demonstrated that spray drying
temperature had significant effect on solubility characteristics of yak milk powder (P < 0.05). Yak milk powder produced
at 170/73℃ had high hydration capacity, bulk density and solubility and small repose angle and dispersion time, showing
better solubility than those produced at other spray drying temperatures. The cluster analysis could be used to distinguish the
solubility of yak milk powder produced at different spray drying temperatures, thereby providing a theoretical reference to
distinguish the quality of yak milk powder produced by spray drying.

Key words: spray drying temperature, solubility, yak milk powder, cluster analysis
