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。
Stability of Enzyme Activity Immobilized on Glycosylated Egg White Beads and Some General Carriers in a Flow System
immobilized enzyme egg white glycosylation
2009/7/8
Ttypsin and α-amylase were immobilized on glycosylated egg white-beads by simple incubation of the beads in a solution of an enzyme for 24 h at 30°C. This process included no artificial chemical modif...
Effects of Fructose-Isoflavone Diet on Plasma Isoflavonoids and Cecal Enzyme Activity in Mice
fructose starch daidzeln
2009/6/18
This paper studies the effects of fructose diet on plasma isoflavonoids and floral enzyme activities in adult mice. Male 6-week-old mice were fed a fructose-isoflavone (FI) diet or a starch-isoflavone...
Enzyme Activity of Lysozyme-Dextran Complex Prepared by High Pressure Treatment
high pressure treatment lysozyme protein engineering
2010/11/23
The relative activity of lysozyme by high pressure treatment over the pressure range of 50-300 MPa for 10 min at 0, 35 and 60°C was investigated. The activity gradually decreased by treatment at more ...
