Evaluation of flour protein for different bread wheat genotypes

Abstract

Six different bread wheat genotypes; two Egyptian commercial varieties (control); Giza-168 and Gemmeiza-11, and four promising lines; L84 and L148, resulted via hybridization and M10 and M34 via radiation mutation program) were rheologically evaluated using extensograph and for protein, analysis using sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE). The radiation mutant M10 and M34 had the highest maximum resistance which is a very good indicator of strong gluten. The amount of gluten content was higher in M10, L148, and M34 compared to the control samples Gz168 and Gm11. Sulfide amino acids (CYS and MET) are slightly higher in M10. The electrophoretic results and amino acid analyzers show that the best technological quality was exhibited by M10. Radiation mutants wheat genotypes have a protein with good characteristics, mainly gluten which is significantly higher compared to control samples. The rheological properties measured as extensograph and gel electrophoresis were much better in irradiated lines M10 and M34.

Penentuan Kadar Lemak Pada Tepung Terigu Dan Tepung Maizena Menggunakan Metode Soxhlet

“…Gandum dikelompokkan berdasarkan kandungan proteinnya, yaitu hard red winter, soft red winter, hard red spring, hard white, soft white, dan hard grain. Perbedaan jenis gandum yang digunakan akan mempengaruhi komposisi kimia tepung terigu (Abdelaleem & Al-Azab, 2021). Beberapa penelitian menunjukkan variasi kandungan lemak pada tepung terigu, yaitu 2,39% (Dhillon et al, 2020), 1,6% (Raya et al, 2022), dan 1,5% (Dobhal & Awasthi, 2021), 0,2-2,1% (Prabhasankar & Rao, 1999).…”

Karakteristik fisikokimia petis bubuk dari rebusan udang dengan jenis bahan pengisi yang berbeda

“…Hal ini menunjukkan bahwa setiap bahan pengisi memiliki karakteristik tersendiri dalam kandungan kadar proteinnya. Tepung terigu memiliki kadar protein sebesar 12-16% sementara tepung beras 8,9% (Abdelaleem et al, 2021;Nandiyanto et al, 2022). Sementara itu, tepung ubi jalar ungu memiliki kadar protein paling rendah apabila dibandingkan dengan tepung terigu dan beras, yaitu 2,79-3,01% (Alifianita & Aan, 2022;Fadhli et al, 2023).…”
