According to European Food Safety Authority (EFSA), dietary fibers are defined as, “non-digestible carbohydrates plus lignin, including all carbohydrate components occurring in foods that are non-digestible in the human small intestine and pass into the large intestine.” Plants such as wheat bran, barley, bean, lentil, and almond are rich in insoluble dietary fibers. These fibers are insoluble in water as they form that part of a plant which is not soluble in water, such as cell wall (cellulose, lignin, and tannins). Insoluble fibers do not dissolve in water, do not form gels, and are less readily fermented. They are predominantly found in grains and vegetables and help with digestive functions. ------------------------------- 1. Micromarkets are defined as the further segments and sub-segments of the global insoluble dietary fibers market included in the report. 2. Core competencies of companies are studied in terms of their key developments and key strategies adopted by them to sustain their position in the insoluble dietary fibers market.
