Two protein isolates (PI1 and PI2) were prepared from sunflower meal produced in Bulgaria. They were obtained by using isoelectric or ethanol precipitation following the extraction of the proteins with 10% NaCl. Their amino acid composition and water solubility as a function of pH and presence of NaCl were investigated. Lysine was established as the first limiting amino acid in the protein isolates with amino acid scores of 35.81% (PI1) and 43.09% (PI2). Both protein isolates contained…

Physicochemical, structural, and functional properties of protein fractions and protein isolate from jackfruit seeds.

The physicochemical, structural, and functional properties of albumin, globulin, glutelin, and protein isolate (JSPI) extracted from jackfruit seeds were investigated. Protein fractions and JSPI were

Chia (Salvia hispanica) protein fractions: characterization and emulsifying properties

A material with a high content of fibers and proteins is generated as a by-product of the chia oil extraction process. A strategy to add value to this by-product is to evaluate its possible use as a

By-products of the oil industry as sources of amino acids in feed

Glutamic acid, aspartic acid, leucine and valine were the most abundant amino acids in all tested by-products of the oil industry, therefore, partial substitution of protein sources in feeds with proteins from theOil industry by- products may improve feed quality.

Comparison ofLupinus angustifoliusprotein digestibility in dependence on protein, amino acids, trypsin inhibitors and polyphenolic compounds content

Lupine seeds are proposed as a source of valuable protein in human and animal nutrition. However, not only protein content but its bioavailability is important. Thus, the protein digestibility of

Preliminary Characterisation of Wastes Generated from the Rapeseed and Sunflower Protein Isolation Process and Their Valorisation in Delaying Oil Oxidation

Since rapeseed and sunflower meals are two of the most representative oilseed crops in the world, this study was focused on ethanol-wash solutes (EWS) obtained as wastes from the protein isolation



OptimizatiOn Of prOtein extractiOn frOm sunflOwer meal prOduced in Bulgaria

It was established that increases of pH in the range from 2 to 10 constantly enhanced protein extractability, and by extracting 10% sunflower meal with 10% NaCl, at pH6 and 40оС for the period of 60-75 min, a protein yield greater than 50% at diminished protein-phenol interaction could be achieved.

Isolation and characterization of the major protein fraction of sunflower seeds.

The major protein fraction in sunflower seeds was isolated in a form judged homogeneous by gel filtration, gel electrophoresis and ultracentrifugation, and information on molecular conformation from circular dichroism studies is presented.

Countercurrent extraction-isoelectric precipitation of sunflower seed protein isolates

A countercurrent extraction-isoelectric precipitation procedure for the preparation of protein isolates from defatted sunflower seed meal is described, resulting in a white, bland and highly pure protein isolate.

Sunflower Protein Concentrates and Isolates Prepared from Oil Cakes Have High Water Solubility and Antioxidant Capacity

Increasing the applications of industrial by-products is of great interest. Therefore, in the present study, sunflower oil cake from a local oil manufacturing company was used to obtain soluble

Characterization of enzymic sunflower protein hydrolyzates

Sunflower meal (SFM) proteins are denatured during the process of oil extraction, which greatly limits their functional and nutritional properties. Protein hydrolysates were prepared from defatted
