The aim of this study was the determination of lactoferrin in goat milk using HPLC method. Milk samples were collected at a goat farm in the South Moravia Region, the Czech Republic. It were establish...
A Novel Method for the Detection of Protease and the Development of Extracellular Protease in Early Growth Stages of Lactobacillus delbrueckii ssp. bulgaricus
extracellular protease Lactobacillus delbrueckii ssp. bulgaricus lactic acid bacteria microplate
2008/3/28
A novel method of rapid detection using microplate wells with casein and calcium ions was developed for measuring protease activity. This new method is based on the theory that the hydrolysis by the p...
A Method to Use Leuconostoc mesenteroides ssp. cremoris 91404 to Improve Milk Fermentations
Leuconostoc diacetyl cultured buttermilk
2008/3/27
Leuconostoc species are frequently used in mesophilic cultures to produce aroma during milk fermentations.Leuconostoc mesenteroides ssp. cremoris 91404 was selected as an aroma producer in preparation...
A new method was developed for obtaining pure ß-CN. Calcium caseinate (3%) was reconstituted, renneted to form a gel, cooled (4°C) to allow ß-CN dissociation from the caseinate gel, and ce...
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,...
Vane Method to Evaluate the Yield Stress of Frozen Ice Cream
vane method rheology ice cream yield stress
2008/3/25
The ability of ice cream to be dipped or scooped is a direct consequence of yield stress; however, yield stresses of frozen ice cream have not been quantified because of the lack of suitable testing e...
Method for Assaying Volatile Compounds by Headspace Gas Chromatography and Application to Growing Starter Cultures
headspace gas chromatography diacetyl leuconostoc mixed culture
2008/3/22
Automatic headspace gas chromatography was used to assay volatile compounds in fermented milks, including diacetyl, which is of particular interest because of its aromatic properties. -Acetolactic aci...
A Method for Manufacturing Reduced Fat Mozzarella Cheese
Mozzarella cheese reduced fat physical properties
2008/3/22
Mozzarella cheese was manufactured to contain up to 50% less fat than conventional part-skim Mozzarella cheese. Milk, which had been standardized to a casein to fat ratio of 1.2, 1.6, 2.0, or 2.4, was...
Detection of Penicillin G in Milk Using a Conductimetric Method
milk penicillin G conductance Bacillus stearuthennophilus
2008/3/22
A highly sensitive method was developed that used conductance measurement for the detection of penicillin G in milk. The method is based on the inhibition by the antibiotic on the growth of Bacillus s...
