    摘要:

    设置不同食盐添加量(10%,15%,20%,25%,30%)对方竹笋进行蒸煮处理,研究其对盐笋干总糖、还原糖、可溶性蛋白、游离氨基酸、NaCl、亚硝酸盐含量以及含水率、复水比、色泽和感官评分等的影响。结果表明:含水率随蒸煮时间的增加而下降,食盐添加量越大,下降速度越快;复水比随复水时间的增加而增大,当复水比基本不再增加时,其由大到小依次为10%>15%>20%>30%>25%;总糖、还原糖、可溶性蛋白和游离氨基酸含量均随盐量的增加而减小;不同盐量处理盐笋干NaCl含量差异显著(P<0.05),随盐量的增加而增大,且不同盐量处理亚硝酸盐含量均低于1.39 mg/kg,含量较低且随盐量的增加而减小;同时,不同盐量处理盐笋干的色差(ΔE)值与鲜方竹笋相差均大于2,差异显著,且食盐添加量低的处理盐笋干感官评分更高。综上,当盐煮干制方竹笋盐量控制为10%~15%时,更有利于保持盐笋干的营养和感官品质及复水性能。

    Abstract:

    Different amounts of salt (10%, 15%, 20%, 25%, and 30%) were set to cook Chimonobambusa quadrangularis shoots. The effects of salt amount on total sugar, reducing sugar, soluble protein, free amino acid, NaCl, nitrite, as well as moisture content, rehydration ratio, color, sensory score, were studied. The results showed that the water content decreases with the increase of boiling time, showing the salt amount dependent. The rehydration rate increased with the rehydration time, and when it basically stops increasing, the rehydration ratio was 10%>15%>20%>30%>25% in descending order. The total sugar, reducing sugar, soluble protein, and free amino acid content all decreased with the increase of salt amount. The NaCl content of salt-dried bamboo shoots with different salt amounts was significantly different (P<0.05), increased with the increase of salt amount. The content of nitrite was lower than 1.39 mg/kg in different salt amounts, and decreased with the increase of salt amount. Moreover, the color difference (ΔE) of salt- dried bamboo shoots with different salt amounts was greater than 2, compared with that of fresh bamboo shoots. A significant difference, and the sensory score of salt- dried bamboo shoots with low salt addition was relative higher than the high salt addition. It was found that the nutritional and sensory qualities of the salt-dried bamboo shoots and its rehydration performance could be maintained, when the salt rate was controlled at 10%~15%.
