Isolation and partial characterization of bovine rumen muscle proteins

Creator:: Perera, Conrad Ostwald
Abstract:: Investigations were conducted to determine the nature, type, functional properties and the amounts of different proteins found in bovine rumen tissue. Data concerning the effect of pH and salt concentration on the extractability of proteins from rumen tissue indicated that 92% of the proteins could be extracted in aqueous solutions...

Methods of extraction and characterization of polyphenol oxidase from d'Anjou pears (Pyrus Communis L.)

Creator:: Smith, Denise Myrtle
Abstract:: Using phenolic scavengers different methods were examined to determine the optimum conditions for extracting polyphenol oxidase (PPO) from d'Anjou pears. Efficiency of the extraction was evaluated based on browning of the extract, PPO activity per g of pear tissue, absorption scan of 410 nm to -240 nm, and the isozyme...

Purification and properties of d'Anjou pear (Pyrus communis, L.) polyphenol oxidase

Creator:: Wissemann, Kimberly Warner
Abstract:: Polyphenol oxidase (PPO) from d'Anjou pears was purified and some molecular properties were studied. The extraction of PPO was accomplished in the presence of the phenolic binder AG 2X-8 and Triton X-100. Chlorophyll pigment was removed by chromatography resulting in a clear, colorless enzyme extract. Three fractions of pear PPO...

Purification of strawberry polyphenol oxidase and its role in anthocyanin degradation

Creator:: Wesche-Ebeling, Pedro Alfredo E.
Abstract:: Polyphenol oxidase (PPO) from strawberries was purified, partially characterized, and used to study its role in the degradation of anthocyanin pigments. The extraction method included the use of a buffered solution containing the phenolic binders Polyclar AT and Amberlite XAD-4. Addition of Triton X-100 resulted in an increase of the...

Development of analytical methodology for verification of authenticity of apple juice

Creator:: Lee, Hyoung S.
Abstract:: Apples growing in New Zealand, Argentina, Mexico, Michigan and Washington were used to provide the compositional data and to develop the analytical procedures for the use in verification of authenticity of apple juices. High Performance Liquid Chromatography (HPLC) techniques were applied for glucose, fructose, sucrose, sorbitol, malic, citric, quinic, shikimic,...

Effects of cyclopropenoid fatty acids on liver plasma membranes of rainbow trout (Salmo gairdneri)

Creator:: Marino, Donald R. (Donald Robert)
Abstract:: Cyclopropenoid fatty acids (CPFA), which are a group of fatty acids produced by plants of the order Malvales, are known to induce adverse physiological effects when administered to a variety of animal species. A structurally strained cyclopropene ring is present in all CPFA and is believed responsible for the toxic...

Composition and in vitro digestion of barley, oat, and wheat brans

Creator:: Gangloff, Mary Beth
Abstract:: In the field of nutrition, complex carbohydrates have become increasingly important in the last decade. The fiber fraction of foods has been implicated as modifying the etiology of several chronic diseases and the starch fraction is important with respect to the glycemic index of foods. This study has focused on...
