To establish an infection, bacteria must first adapt to the host environment and grow. For mastitis, the media in which bacteria must adapt to is milk. Mammary pathogenic Escherichia coli may express factors that are important for these bacteria to grow in milk and establish both acute and chronic infections of the mammary gland. We have used shotgun expression proteomics to determine the chang...

We identified the proteins synthesized by Lactobacillus delbrueckii subsp. bulgaricus strain LBB.B5 in laboratory culture medium (MRS) at 37°C and milk at 37 and 4°C. Cell-associated proteins were measured by gel-free, shotgun proteomics using high-performance liquid chromatography coupled with tandem mass spectrophotometry. A total of 635 proteins were recovered from all cultures, among which ...

The use of dairy products in the recipes sausage allows to significantly improve nutritional, consumer and structural-mechanical properties finished products. There are several technological ways add additional milk proteins products, particular semi-smoked sausages. introduction these components is possible by adding protein form dry or mixtures, using ready-made (cheese cheese products), as w...

Plant-based milk alternatives are surging in popularity, although many examples have poor nutritional value compared to cow's milk. At the same time, protein concentrates and isolates from pea other pulses increasingly being recognised for their potential as functional nutritious ingredients. This review contains an overview of pulse proteins dry wet fractionation methods used produce high-prot...

Two major milk whey proteins, β-lactoglobulin and α-lactalbumin, are among the main cow milk allergens and can cause allergy even at a very low concentrations. Therefore, these proteins are interesting targets in food analysis, not only for food quality control but also for highlighting the presence of allergens. Herein, a sensitive analysis for β-lactoglobulin and α-lactalbumin was developed u...

Human milk provides the best nutrition for newborn. Nowadays, more and women choose to collect freeze their own later use. However, there has been no consensus on freezing conditions standard criteria thawing. This study aimed evaluate effect of different freeze-thaw processes (frozen at −18 °C −60 30 d, followed by placing in air 4 10-h stationary, 25 1-h stationary shaking tepid water 45 1 mi...

Advances in genetic technology have made it possible to consider making substantial changes either in the composition of milk or in the production of entirely new products in milk. The technological capabilities that have given rise to the introduction and expression of new genes in animals are discussed. Examples are given of transgenic animals that express foreign proteins in their milk. Adva...

Nowadays, the quality of any food used for human consumption is, to a considerable extent, considered by its possible contribution to the maintenance or improvement of the consumer's health. In developed countries there is increasing interest in goat milk and its derivates, the quality of which is considered of special importance in the light of current tendencies favouring healthy eating. In p...

Twenty crossbred lactating multiparous cows were used in a 28-day study to compare dry matter intake (DMI), milk yield, milk composition and Bacillus thuringiensis (Bt) protein concentrations in plasma when fed diets containing Bollgard II(®) cottonseed (BGII) or a control non-genetically modified isogenic cottonseed (CON). Bollgard II cottonseed contains the Cry1Ac and Cry2Ab insecticidal prot...
