Casein Cross-linked Polyacrylamide Hydrogels: Study
The polymeric hydrogels composed of polyacrylamide and food protein casein have been synthesized for the purpose of studying their swelling and drug release behaviour. The two samples, differing in cross-linking ratio, show almost Fickian swelling behaviour (n50.50) except the less cross-linked sample at pH 7.0 for which swelling exponent n was

Casein-based hydrogels: A mini-review - ScienceDirect
The study results showed that the WHC of casein-based hydrogels can be defined as the water entrapped in the hydrogel matrix while it is in a state equilibrium with the medium. The authors demonstrated that a hydrogel’s WHC depends primarily on crosslink density, solvent quality, and temperature.
Casein micelle hydrogels were developed using transglutaminase (Tgase) as a crosslink agent in order to encapsulate anthocyanins from jaboticaba fruit (Myrciaria cauliflora).Spray dried casein micelles (CMs) powder was rehydrated in ultrapure water at a concentration of 4.5% w/w, and Tgase was added at 3 units/g of casein.
Rheological Monitoring of Polyacrylamide Gelation
Dynamic shear oscillation measurements at small strains are used to characterize the polymerization process in situ and the viscoelastic properties of cross-linked polyacrylamide hydrogels. Hydrogels are synthesized by free-radical redox polymerization of acrylamide (8 wt %) for different concentrations of cross-linker, N,N‘-methylenebis(acrylamide) (BIS), at different temperatures.
The problem of the present invention is to provide biocompatibility and safe, and can in both bag hydrophily, hydrophobic agent, use feeling excellent gel film when in addition applied to skin of people etc..It is related to a kind of gel film as the method for solving problem of the present invention, it is the gel film comprising lipid peptide type gelling agent and high-molecular compound
Cheese Whey Processing: Integrated Biorefinery Concepts
Cheese whey constitutes one of the most polluting by-products of the food industry, due to its high organic load. Thus, in order to mitigate the environmental concerns, a large number of valorization approaches have been reported; mainly targeting the recovery of whey proteins and whey lactose from cheese whey for further exploitation as renewable resources.

- What is partially hydrolyzed polyacrylamide (PHPA)?
- Partially hydrolyzed polyacrylamide (PHPA) is a widely used polymer in the oil and gas industry due to its lesser cost and good water solubility. PHPA is used as a functional additive in water-based drilling fluids. The PHPA mud system stabilizes shale formations and influences cuttings and wellbore stability.

- How does PHPA work?
- PHPA is formulated for easy mixing with improved dispersion to eliminate "fish eyes", which occurs when mixing either large quantities rapidly or mixing high polymer concentrations where good mixing equipment is unavailable. PHPA acts as a viscosifier, friction reducer, and flocculants, while also providing some fluid-loss control.
- What is a PHPA mud system?
- The PHPA mud system stabilizes shale formations and influences cuttings and wellbore stability. PHPA can be used in mud systems varying from low solids to weighted muds systems utilizing fresh or saltwater. PHPA is a white granular powder, anionic in nature having a specific gravity of 1.25 to 1.40 and a bulk density of 40 to 46 lb/ft 3.
