Hydrolysis Characteristics of Bovine Milk Fat and Monoacid Triglycerides Mediated by Pregastric Lipase from Goats and Kids
caprine pregastric lipase milk fat tributyrylglycerol monoacid triglycerides
2008/3/27
Commercial extracts from oro-pharyngeal tissues of goats and kids have been used as the source of pregastric lipase and have been processed to yield partially purified samples of the primary pregastri...
A Semiautomated Reflectance Colorimetric Method for the Determination of Lipase Activity in Milk
Pseudomonas lipase milk quality psychrotroph
2008/3/26
Measurement of heat-stable lipase activity in dairy products relies on methods that are slow or that cannot be used in turbid solutions, which limits their industrial value. A need exists for a rapid,...
Characteristics of Tributyroylglycerol Hydrolysis Mediated by Partially Purified Lamb Pregastric Lipase
lamb pregastric lipase hydrolysis tributyroylglycerol
2008/3/25
A partially purified pregastric lipase from lambs was used as a catalyst for the hydrolysis of tributyroylglycerol. The reaction was followed by pH-stat autotitration of the released butyric acid. Int...
Isolation of Lipase-Active Fractions from Ultra-High Temperature-Processed Milk and Their Patterns of Releasing Fatty Acids from Milk Fat Emulsion
lipase ultra-high temperature releasing patterns fatty acids
2008/3/22
To examine residual lipase activities in UHT-processed milk samples, two protein isolates were prepared, one from aqueous supernatant and the other from milk fat globule membrane. Results of DEAE-cell...
Interesterification of Milk Fat with Oleic Acid Catalyzed by Immobilized Rhizopus oryzae Lipase
interesterification immobilized lipase milk fat oleic acid
2008/3/22
Milk fat was interesterified with oleic acid by catalysis of an immobilized lipase in a microaqueous two-phase system. A commercial lipase from Rhizopus oryzae and a controlled pore glass carrier were...
Influence of Milk Proteins on the Thermostability of the Lipase from Pseudomonas fluorescens 33
lipase milk proteins thermostability psychrotrophs
2008/3/18
The effects of some milk proteins on the thermostability of the lipase from Pseudomonas fluorescens 33 were investigated. All purified milk protein fractions except -casein that dissolved in phosphate...
