[Reduction of crude fiber content in safflower meal (Carthamus tinctorius L) and its potential use in human food].
The purpose of this work was to reduce the content of crude fibre (CF) and to determine the content of phenolics compounds (PC) and trypsin inhibitors (TI) in safflower meal (SM), in order to recommend the possibility of utilization it in human food. The SM (23.3% of CF, 22.4% of protein and 1.75% of PC was grinded in a blender and in a hammer mill respectively, after that, they were classified in particle size by sieving and compared with the SM and their fractions. Grinding in hammer mill was more effective; in this process the yield of the fine fractions was 60.5% and the contents of protein and PC were concentrated by 46.7% and 50%, respectively. The test of TI in SM resulted negative. Grinding and sieving showed to be an easy and cheap mechanical size separation process to reduce CF, which also increase the protein content with a good yield of material. It should be possible the utilization of the fine fractions in human food, provided that the level of incorporation in a food product will be low.
