Degumming of rice bran oil

Abstract Rice bran oil (RBO) is an excellent cooking and salad oil due to its high smoke point and delicate flavor. The nutritional qualities and health effects of RBO are also established. The content of phospholipids in crude RBO is a major problem during processing of the oil in various food applications. It has been reported that water degumming process is suitable for the removal of hydratable phospholipids (HPL). Nonhydratable phospholipids (NHPL) can be removed only during acid degumming or enzymatic degumming processes. Rapid equilibrium extraction has been found suitable for reducing the phospholipid content of RBO. Many researchers have found the efficiency of water, acid, and enzymatic degumming of RBO. New techniques of degumming for RBO have also been established using ultrafiltration and nanofiltration membranes. The presented techniques are individually significant based on phospholipids efficiency. Hence, the present paper reviews the prevailing techniques of RBO degumming.

Tropical Roots and Tubers: Production, Processing and Technology

Roots and tubers are considered as the most important food crops after cereals and contribute significantly to sustainable development, income generation and food security especially in the tropical regions. The perishable nature of roots and tubers demands appropriate storage conditions at different stages starting from farmers to its final consumers. Because of their highly perishable nature, search for efficient and better methods of preservation/processing have been continuing alongside the developments in different arena. This book covers the processing and technological aspects of root and tuber foods, detailing the production and processing of roots and tubers such as taro, cassava, sweet potato, yam and elephant foot yam. Featuring chapters on anatomy, taxonomy and physiology, molecular and biochemical characterization, GAP, GMP, HACCP, Storage techniques, as well as the latest technological interventions in Taro, Cassava, Sweet potato, yam and Elephant foot Yam.
