Effects of cow’s milk beta-casein variants on symptoms of milk intolerance in Chinese adults: a multicentre, randomised controlled study

Nutrition Journal, 2017
Background A major protein component of cow’s milk is β-casein. The most frequent variants in dairy herds are A1 and A2. Recent studies showed that milk containing A1 β-casein promoted intestinal inflammation and exacerbated gastrointestinal symptoms ...

Potential Biological Activities of Peptides Generated during Casein Proteolysis by Curly Kale (Brassica oleracea L. var. sabellica L.) Leaf Extract: An In Silico Preliminary Study

Foods, 2021
This study is a brief report on the proteolytic activity of curly kale leaf extract against casein. Casein degradation products and an in silico analysis of the biological activity of the peptides obtained was performed.

Effects of β- and κ-casein, and β-lactoglobulin single and composite genotypes on milk composition and milk coagulation properties of Italian Holsteins assessed by FT-MIR

Italian Journal of Animal Science, 2021
The present study aimed to investigate the effect of β- and κ- casein, and β-lactoglobulin genotypes on milk composition and milk coagulation properties predicted using Fourier-transform mid-infrared spectroscopy (FT-MIR).

Epigallocatechin-3-gallate enhances sterilization of irradiated whole bovine casein and protects alpha and beta caseins from gamma radiation: Depending on polyphenol/protein ratio

Journal of Radiation Research and Applied Sciences, 2023
The increasing use of milk proteins in medicine requires developing effective processes for sterilizing milk formulations. It was found that epigallocatechin-3-gallate (EGCG) reduce bacterial flora in total casein, depending on the concentration of EGCG.

Hypoallergenic and Physicochemical Properties of the A2 β-Casein Fractionof Goat Milk

Food Science of Animal Resources, 2017
Goat milk has a protein composition similar to that of breast milk and contains abundant nutrients, but its use in functional foods is rather limited in comparison to milk from other sources.

Application of Multiharmonic QCM-D for Detection of Plasmin at Hydrophobic Surfaces Modified by β-Casein

Chemosensors, 2022
Plasmin protease plays an important role in many processes in living systems, including milk. Monitoring plasmin activity is important for control of the nutritional quality of milk and other dairy products.

Post-weaning A1/A2 β-casein milk intake modulates depressive-like behavior, brain μ-opioid receptors, and the metabolome of rats

iScience, 2021
Summary: The postnatal period is critical for brain and behavioral development and is sensitive to environmental stimuli, such as nutrition. Prevention of weaning from maternal milk was previously shown to cause depressive-like behavior in rats ...

Enzymatic Encoding of Topology in an Intrinsically Disordered Single‐Chain Protein

Angewandte Chemie, EarlyView.
Enzymatic intramolecular cross‐linking enables topology control in intrinsically disordered proteins, yielding SCNPs with reproducible cavity architectures. Using β‐casein and microbial transglutaminase, sparse, sequence‐resolved constraints drive compact collapse without inducing secondary structure.

Kinetics of heat-induced interactions among whey proteins and casein micelles in sheep skim milk and aggregation of the casein micelles

Journal of Dairy Science, 2022
: The interactions among the proteins in sheep skim milk (SSM) during heat treatments (67.5–90°C for 0.5–30 min) were characterized by the kinetics of the denaturation of the whey proteins and of the association of the denatured whey proteins with casein
