Milk whey—commonly known as cheese whey—is a by-product of cheese or casein in the dairy industry and contains usually high levels of lactose, low levels of nitrogenous compounds, protein, salts, lactic acid and small amounts of vitamins and minerals. Milk whey contains several unique components like immunoglobulins (Igs), lactoferrin (Lf), lactoperoxidase (Lp), glycomacropeptide (GMP) and sphi...

whey contains more than half of total solids present in the original milk, which includes 20% of the proteins, most of the lactose, minerals and water soluble vitamins. in this study, selective separation of whey components by aphron flotation (separation of ultrafine particles by micro-bubbles) has been investigated. it has been shown that it is possible to recover valuable components of whey ...

Our objective was to determine if annatto color or bleaching had any influence on ultrafiltration (UF) flux during production of 80% whey protein concentrate (WPC) or 80% serum protein concentrate (SPC). Cheddar cheese whey (18 vats using 900 kg of whole milk each) and microfiltration (MF) permeate of skim milk (18 processing runs using 1000 kg of skim milk each) were produced. The 18 runs were...

BACKGROUND Cardiovascular diseases (CVDs) are the greatest cause of death globally, and their reduction is a key public-health target. High blood pressure (BP) affects 1 in 3 people in the United Kingdom, and previous studies have shown that milk consumption is associated with lower BP. OBJECTIVE We investigated whether intact milk proteins lower 24-h ambulatory blood pressure (AMBP) and othe...

37 38 39 Physical, thermal and microstructural properties of whey protein isolate (WPI) and chicken 40 skin gelatin mixtures were investigated. This is a first study on the compatibility of an 41 unutilised gelatin source from chicken skin with a well-characterised food protein. The 42 physical-chemical and rheological properties of chicken skin gelatin alone, were reported in 43 our previous p...

As part of a growing health and wellness trend, food and beverage manufacturers are boosting the protein content of products. Many food and beverage manufacturers use whey proteins as the protein source of choice for product innovation. Expanded utilization of these ingredients holds great potential for creating even more new formulation possibilities through improvements in whey quality and pe...

OBJECTIVES Children with severe cerebral palsy (CP) commonly have gastrointestinal (GI) dysfunction. Whey-based enteral formulas have been postulated to reduce gastroesophageal reflux (GOR) and accelerate gastric emptying (GE). The authors investigated whether whey-based (vs casein-based) enteral formulas reduce GOR and accelerate GE in children who have severe CP with a gastrostomy and fundopl...

Background: Protein quantity and quality at a meal affect muscle protein synthesis (MPS); however, long-term effects of protein distribution at individual meals on adult muscle mass remain unknown. Objective: We used a precise feeding protocol in adult rats to determine if optimizing postmeal MPS response by modifying the meal distribution of protein, and the amino acid leucine (Leu), would aff...

A recent study by Lacroix et al (1) compared the postprandial utilization of nitrogen from 3 different proteins, namely micellar casein (“slow protein”), milk soluble protein isolate (“fast protein”), and total milk protein (another “slow protein”). Their data suggest that slow protein induces better postprandial nitrogen utilization than does fast protein. According to Lacroix et al, “This res...

Dipeptidyl-peptidase IV (DPP-IV) is an enzyme with numerous roles within the body, mostly related to regulating energy metabolism. DPP-IV is also a myokine, but the stimulus for its release is poorly understood. We investigated the transcription and release of DPP-IV from skeletal muscle in a three-part study using C2C12 myotube cultures, an acute rat exercise and postexercise feeding model, an...
