Extraction optimization and structural characterization of soluble dietary fiber in foxtail millet and its inhibitory activities on colon cancer
Soluble dietary fiber has anti-tumor effect and is closely related to human health. At present the structure of soluble dietary fiber from foxtail millet (FMB-SDF) and its anti-tumor effect remain unclear. In this study, the structure of FMB-SDF was characterized, and its effects on the colon cancer were investigated. The results showed that under optimal extraction conditions the yield of FMB-SDF was 14.25 %. Based on the monosaccharide composition, methylation results and NMR analysis, the preliminary structure of FMB-SDF was inferred to be a glucan. Interestingly, FMB-SDF markedly inhibited the colony formation ability of HCT116 and HT-29 cells and could significantly induce the increase of reactive oxygen species (ROS) and apoptosis of HCT116 and HT-29 cells. The results of animal experiments showed that FMB-SDF could significantly alleviate clinical symptoms of colon cancer in mice. These results provide a theoretical basis for the exploitation and utilization of FMB-SDF against colon cancer.
期刊介绍：
Journal of Functional Foods continues with the same aims and scope, editorial team, submission system and rigorous peer review. We give authors the possibility to publish their top-quality papers in a well-established leading journal in the food and nutrition fields. The Journal will keep its rigorous criteria to screen high impact research addressing relevant scientific topics and performed by sound methodologies.
The Journal of Functional Foods aims to bring together the results of fundamental and applied research into healthy foods and biologically active food ingredients.
The Journal is centered in the specific area at the boundaries among food technology, nutrition and health welcoming papers having a good interdisciplinary approach. The Journal will cover the fields of plant bioactives; dietary fibre, probiotics; functional lipids; bioactive peptides; vitamins, minerals and botanicals and other dietary supplements. Nutritional and technological aspects related to the development of functional foods and beverages are of core interest to the journal. Experimental works dealing with food digestion, bioavailability of food bioactives and on the mechanisms by which foods and their components are able to modulate physiological parameters connected with disease prevention are of particular interest as well as those dealing with personalized nutrition and nutritional needs in pathological subjects.
