Title: Factors Affecting Protein Extractability of Defatted Karkade (Hibiscus Sabdariffa) Seed Flour
Authors: Hamza M. Abu-Tarboush
Issue Date: 1995
Abstract: Karkade seed flour was defatted by two different methods. The cold method was better than the hot method in terms of protein extractability. Protein extractability was studied under various conditions of pH (2-12), time (30, 45, 60 min) salt type (CaCl2, NaCl), solvent; flour ratio (10:1, 20:1) and salt concentration (0.2, 0.4, 0.6, 0.8 and 1M). Results showed that protein extractability was dependent on pH, type of salt and salt concentration. Higher yield was obtained with CaC2 than NaCl. Highest protein yield was obtained at pH11 and at 0.4 M CaCl. Highest protein yield was obtained at pH 11 and at 0.04M CaCl2 .
