臭氧处理对竹笋木质化及相关酶活性的影响（Effects of O3on Lignification and Related Enzyme Activity in Bamboo Shoots）
竹笋 臭氧 木质化 酶活性
2010/12/29
为探索臭氧对竹笋木质化的影响，研究了100、200或300μL/L臭氧处理30min对冷藏（1±1）℃竹笋木质化及相关酶活性的影响。结果表明：臭氧处理可延缓竹笋冷藏期间硬度的上升，降低呼吸强度和乙烯释放量;可延缓PAL、POD和PPO活性的增加，其木质素和纤维素的含量分别比对照低7%～12%和8%～14%，霉变率比对照低71%～84%。臭氧处理延缓了竹笋的木质化进程。
梳解法制备竹纤维的力学模型（Mechanical Model of Processing Bamboo Fiber with Combing Method）
竹纤维 梳解法 力学模型
2010/12/28
通过研究梳解法制备竹纤维的原理，提出竹子梳解制纤中平均梳解力的概念；运用动力学方法，建立竹纤维平均梳解力与纤维长度、细度关系的计算模型。对模型进行分析和验证，结果表明：模型表述的平均梳解力、滚筒转速及滚筒梳针参数与竹纤维长度、细度的关系正确；运用模型计算竹纤维长度的结果与实验结果相吻合，此模型可用于梳解法制备竹纤维的长度、细度预测与计算。
1-MCP处理对脱壳茭白木纤化与细胞结构的影响（Effect of 1-methylcyclopropene (1-MCP) on Lignification and Cell Ultrastructure of Peeled Water Bamboo Shoot）
茭白 1-MCP 木纤化
2010/1/28
研究了不同体积分数1-MCP处理对常温和低温贮藏期间脱壳茭白木纤化以及细胞超微结构的影响。结果发现：0.5μL/L的1-MCP处理可较好保持常温和低温条件下茭肉的外观品质，抑制乙烯的产生，减少纤维素含量的增加，抑制可溶性果胶含量的下降和原果胶含量的增加，减轻茭肉木纤化过程。用透射电镜观察常温贮藏6d后的茭肉超微结构，发现1-MCP处理的细胞较对照细胞内含物丰富，胞间连丝仍然清晰，证实了1-MCP处...
