Action of Rennet on Casein as Influenced by Hydrogen Peroxide–Catalase Treatment

The Action of Rennet and of Heat on Milk.

Cooling effects on a model rennet casein gel system: part II. Permeability and microscopy.

Microscopy and permeability studies were performed to further illustrate the cooling effects on rennet casein gel structure and help interpret the rheological observations in the first part of this paper. Samples of gels cooled from 80 to 5 degrees C at four rates (0.5, 0.1, 0.05, and 0.025 degrees C/min) were studied with a confocal laser scanning microscope. A larger number of smaller flocs w...

Cooling effects on a model rennet casein gel system: part I. Rheological characterization.

The gelation of a model rennet casein system was studied during cooling at different rates. During cooling, casein network structure development was proposed to evolve over a few steps at different length scales: molecules, particles, flocs, or network. Rennet casein flocs are fractal in nature, and fractal dimension and floc size are two variables affecting the rheology and microstructure of a...

The Action of Rennin on Casein

In order to determine if the change from casein to paracasein results in the cleavage of any of the elements contained in the casein molecule, it is imperative that pure casein be used as a standard of comparison, and that the rennin activity be positively differentiated from any further proteolyt,ic activity of the enzyme under consideration; for it is quite evident that “Rennin action is prob...

Bile Salt Metabolism as Influenced by Pure Amino Acids and Casein Digests

A non-protein diet supplemented with vitamins fed to a bile fistula dog caused marked reduction in cholic acid and taurocholic acid formation. A mixture of pure amino acids, essential for growth, promoted taurocholic acid production for a limited period. A mixture of amino acids composed of 2 fractions of a casein digest fortified with dl-methionine and dl-tryptophane, (Merck Vuj-N-ix), also re...
