摘要:为研究白水循环对再造烟叶产品品质的影响,分析了再造烟叶生产过程中不同白水循环回用时间下水质、基片物理性能以及成品感官质量的变化情况。研究结果表明,随着白水循环回用,(1)白水理化性质方面,不溶物、可溶物以及不溶物中碳酸钙含量逐渐增加,增加幅度可溶物含量>不溶物含量>不溶物中碳酸钙含量,其中可溶物含量呈现稳定的线性增长趋势；pH值逐渐下降；阳离子需求量逐渐上升；氨氮含量逐渐上升,并且在后期快速上升；电导率呈现显著的对数增长的趋势。(2)基片物理性能方面,松厚度和抗张强度逐渐下降,碳酸钙含量逐渐上升,柔软度先下降后上升。(3)产品感官质量方面,白水的循环回用2d之后,感官质量开始逐渐下降,从第5d开始,感官质量显著下降。

Abstract:For researching the influence of circulating white water on qualities of reconstituted tobacco, the changes of qualities of white water, physical properties of sheet base, and sensory properties of products with different days of water recycling were analyzed. The results showed that: With the recycling of white water, 1) For the aspect of the physicochemical properties of white water, the contents of insoluble substances, soluble substances and calcium carbonate in insoluble substances gradually increased. The comparison of the amounts of variation for different physicochemical properties was as follows: Soluble substance content > insoluble substance content > calcium carbonate content in insoluble substances. Among them, soluble substance content grew with a stable linear trend; the pH value decreased gradually; the cationic demand increased gradually; the ammonia nitrogen content increased gradually and rev up in the later period; the electrical conductivity showed a significant logarithmic growth trend. 2) For the aspect of the physical properties of the sheet base, the bulk and tensile decreased gradually, the calcium carbonate content increased gradually, and the softness decreased at first,then increased. 3) For the aspect of the sensory quality of the products, after 2 days of white water recycling, the sensory quality began to decrease, and from the 5th day, the sensory quality decreased significantly.
