Determination of Biological Activities of Peptides from Cold Pressed Sunflower Meal, The Stability of Bioactive Peptides and Applications in Food Products

Abstract

The procurement of hulled sunflower seed samples, the removal of oil from the kernel using cold press equipment, obtaining cold press cake, preparation of protein isolates, and composition analysis of the cake and protein isolate encompass the 1–6-month period of the thesis work. At this stage, a clear definition and understanding of the raw material to be studied significantly influence the remaining process and analyses. In this context, the primary goal is to analyze the nutritional composition of hulled sunflower seeds, coldpressed cake, and the obtained protein isolate. Additionally, it is crucial within the remaining part of the thesis to determine the suitability of the protein isolation method, decide on and procure the enzymes to be used, establish the working conditions of these enzymes by following similar studies in the literature, and conduct preliminary tests in the laboratory. The all succeeded objectives of 1-6-month period of the project work listed below.
