Conophor nut (Tetracarpidium conophorum) was processed using different heat treatments to explore its full potential as food ingredients. The raw, boiled, and toasted nuts were defatted and the proteins isolated by alkaline solubilization and isoelectric precipitation. The variously processed nuts were analyzed for the proximate and amino acid compositions, and functional properties. The protei...

Tuna processing by-product is estimated at more than 100,000 metric tonnes annually in Iran, which could be a potential source of edible protein in human food. Hence, recovering proteins from tuna by-products is a big achievement in the seafood industry. In this work tuna protein isolates (TPI) were extracted from dark/ red meat using the isoelectric solubilization/ precipitation method. Oxidat...

Jatropha curcas seed cake is a protein-rich byproduct of oil extraction which could be used to produce protein isolates. The purpose of this study was the optimization of the protein isolation process from the seed cake of an edible provenance of J. curcas by an alkaline extraction followed by isoelectric precipitation method via a sequentially integrated optimization approach. The influence of...

The aim of this study was to enhance the nutritional value and functional characteristics muffins by enriching with chickpea protein isolate, while keeping their rheological characteristics. Chickpea Protein isolate (CPI) prepared alkaline solubilization (pH 11), followed isoelectric precipitation at pH 4.5. SDS-PAGE revealed three subunits molecular weights 47, 30 85 kDa; representing globulin...

Two-dimensional polyacrylamide gel electrophoresis (2D-PAGE) is the common method of choice for proteomic analysis. By introducing several small changes, a method was developed that not only improved the resolution and reproducibility of 2D-PAGE but also shortened the time of analysis. Precipitation by alkaline phenol and methanol/ammonium acetate was the choice for protein extraction. However,...
