The Two-Stage Coagulation of Milk Proteins in the Minimum of the Heat Coagulation Time-pH Profile of Milk: Effect of Casein Micelle Size
milk heat stability casein micelle size
2008/4/1
Milks with casein micelles larger or smaller than control milk were prepared by differential centrifugation. The heat stability of these modified milks increased markedly throughout the pH range 6.4 t...
Influence of pH on Protein Interactions and Microstructure of Process Cheese
process cheese microstructure scanning electron microscopy ionic interaction
2008/3/27
During the manufacture of process cheese, biochemical characteristics (casein solubilization, peptization coefficient, and water-holding capacity) were investigated using a combination of microscopic ...
Effects of Limited Proteolysis on the Microstructure of Heat-Induced Whey Protein Gels at Varying pH
whey protein proteolysis gel microstructure
2008/3/26
Whey protein solutions, reconstituted 12% commercial whey protein isolate, were hydrolyzed at pH 7.0 by one of three proteases: trypsin, Neutrase® (from Bacillus subtilis), and a Bacillus lichenif...
A Comparative Study of pH and Temperature Effects on the Acidic Coagulation of Milks from Cows, Goats, and Sheep
acidic coagulation cow milk goat milk sheep milk
2008/3/23
The acidic coagulation of milk from cows, goats, and sheep was studied at various temperatures by a turbidimetric method based on light reflection and capillary viscosimetry. Milk was acidified by hyd...
Mozzarella Cheese: Impact of Whey pH at Draining on Chemical Composition, Proteolysis, and Functional Properties
Mozzarella cheese draining pH composition functional properties
2008/3/22
Cultured low moisture, part skim Mozzarella cheeses were produced using the same milk (185 kg per vat), starter, and coagulant, but with two different whey pH at draining (6.40 and 6.15). Cheese was m...
Effects of pH and Sodium Chloride on the Interactions Between Geotrichum candidum and Brevibacterium linens
Geotrichum candidum Brevibacterium linens interaction pH
2008/3/22
The interactions between 14 isolates of Geotrichum candidum and 14 isolates of Brevibacterium linens were analyzed to understand their behavior in cheese making. Mixed cultures were grown in a peptone...

2008/3/19
The objective of this study was to determine the impact of milling pH and refrigerated storage time on functional properties of unmelted and melted Mozzarella cheese. A "no-brine" Mozzarella cheese-ma...
Mozzarella Cheese: Impact of Milling pH on Chemical Composition and Proteolysis
Mozzarella cheese milling pH composition proteolysis
2008/3/18
The objective of this study was to determine the impact of milling pH on initial chemical composition and proteolytic changes in Mozzarella cheese during refrigerated storage. A new pilot-scale Mozzar...
Increased Nisin in Cheddar-Type Cheese Prepared with pH Control of the Bulk Starter Culture System
nisin lactic acid bacteria cheese
2008/3/18
Five strains of Lactococcus lactis ssp. lactis and one transconjugant strain of Lactococcus lactis ssp. cremoris, previously shown to be nisin producers, were evaluated for nisin production during gro...
