maintaining quality and longevity of cut flowers is one of the critical issues in the floriculture industry, especially in cut flowers; and one of the most important problems in chrysanthemum, as one of the most popular cut flowers. therefore, an experiment was conducted based on completely randomized design as pulse treatment with the three factors: tea extracts with 4 levels (5, 10, 20, and 4...

We develop and apply a molecular theory to study the adsorption of lysozyme on weak polyacid hydrogel films. The theory explicitly accounts for the conformation of the network, the structure of the proteins, the size and shape of all the molecular species, their interactions as well as the chemical equilibrium of each titratable unit of both the protein and the polymer network. The driving forc...

This study presents the design and characterisation of casein−whey protein suspensions (8.0/10.0% (w/w) casein 2.0/2.5% whey protein) mixed with dairy fat (1.0, 2.5 5.0% total fat) processed via pH−temperature-route in preparation for 3D-printing. Mechanical treatment was applied to significantly decrease particle size milk globules increase surface area, creating small (<1 μm) covered proteins...

Foam fractionation is one of the low operating-cost techniques for removing proteins from a dilute solution. The initial bulk solution pH and air superficial velocity play an important role in the foam-fractionation process. Denaturation of proteins (enzymes) can occur, however, during the foam-fractionation process from the shear forces resulting from bursting air bubbles. At the extreme bulk ...

 The a im of th is paper was to study the effects w hey pro t e in c oat i ng on ch e m ic al a nd physic al properties of gut t ed K i l ka dur i ng f roz en stor a ge. Coating of Kilka has done by dipping in whey protein solution with different concentrations of 3, 7, 10 and 13%, for 1h. Then, after being packed in polyethylene dishes, they were covered in cellophane blanket and stored in -18...

The ionic activities and total molalities of sodium, potassium, calcium, lithium, and chloride in a solution of human serum albumin were measured at different values of pH between 4 and 9. The same quantities were measured simultaneously in a protein-free electrolyte solution in membrane equilibrium with the albumin solution. Taking the residual liquid-junction potential and bias from unselecti...
