in this study the bacterial growth inhibitory activity of peptide fragments produced from goat’s milk whey proteins by enzymatic hydrolysis using trypsin, ficin and a combination of both was investigated. goat’s milk whey proteins were isolated and subjected to enzymatic hydrolysis and peptides were purified by ultrafiltration followed by reverse-phase high-performance liquid chromatography (rp...

The nature and interaction of the constituent substances that make up sour-milk dessert with plant-based fillers have been studied by method IR spectroscopy. This is used to study diverse substances. spectral range applied was in 500–4,000 s -1. It found intensity functional groups absorption 2,500–3,500 s-1 due valence vibrations NH-, CH S-H-groups, indicating presence free organic acids, arom...

purpose: to evaluate colostrum total protein differences between left and right breasts and between mothers of boy and girl infants. materials and methods: a cross sectional study for delivery was carried out on 30 boy-delivered and 30 girl-delivered mothers aged 16 to 36 years, conducted at the izadi and al-zahra hospitals in qom city, iran. colostrum was collected from both breasts by manual ...

The changes in milk fat globules and fat globule surface proteins during concentration of whole milk using a pilot-scale multiple-effect evaporator were examined. The effects of heat treatment of milk at 95 degrees C for 20 s, prior to evaporation, on fat globule size and the milk fat globule membrane (MFGM) proteins were also determined. In both non-preheated and preheated whole milk, the size...

Milk is considered a nutritious food because it contains several important nutrients including proteins and vitamins. Conversely, it can be a vehicle for several pathogenic bacteria such as Staphylococcus aureus. This study aimed to analyze the frequency of genes encoding the nine Staphylococcal enterotoxins (SEs) and enterotoxin gene profiles in S. aureus isolates derived from raw bovine milk....

Fast freezing and slow thawing Salmonella anatum cells in various milk components inactivated from 20 to 98% of the cells and damaged 40 to 90% of the cells surviving the treatments. Injured cells failed to form colonies on a selective medium (xylose-lysine-peptone agar with 0.2% sodium deoxycholate) but did form colonies on a nonselective plating medium (xylose-lysine-peptone agar). The major ...

milk proteins provide a natural source of bioactive peptides with potential health benefits and applications in the food industry. the release of these peptides from milk proteins is achieved either by hydrolysis using digestive proteases or by lactic acid bacteria fermentation. peptides, particularly those derived from milk proteins, can exert a wide range of nutritional, functional and biolog...

In tsetse flies, nutrients for intrauterine larval development are synthesized by the modified accessory gland (milk gland) and provided in mother's milk during lactation. Interference with at least two milk proteins has been shown to extend larval development and reduce fecundity. The goal of this study was to perform a comprehensive characterization of tsetse milk proteins using lactation-spe...

Prostate cancer (PCa) is dependent on androgen receptor signaling and aberrations of the PI3K-Akt-mTORC1 pathway mediating excessive and sustained growth signaling. The nutrient-sensitive kinase mTORC1 is upregulated in nearly 100% of advanced human PCas. Oncogenic mTORC1 signaling activates key subsets of mRNAs that cooperate in distinct steps of PCa initiation and progression. Epidemiological...

Breast milk is the best source of nutrition for newborns. content composed water, protein, carbohydrates, fats, vitamins, minerals, antibodies, and enzymes. also contains white blood cells substances that make up baby`s immune system such as immunoglobulins lysozyme. The composition breast can change depending on needs ages baby. Exclusive breastfeeding recommended by many doctors other healthc...
