Effect of processing on the cyanoglucoside content of cassava

Abstract: The efficiency of different processes in reducing the cyanoglucoside (CNG) content of cassava was studied. Maximum retention of CNG (>80%) was observed in baked, fried and steamed tubers. CNG retention in sun-dried chips varied from 30–60%, the retention being governed by the chip thickness. In case of cassava boiled in water, smaller chip size and sufficient water was found to be the ideal condition for maximum CNG removal. There was 25–75% CNG retention in this process, depending on the chip size used. The most effective method for CNG removal was by crushing fresh tuber and subsequent sun-drying, whereby >95% CNG was eliminated. The studies indicated that the mode of processing greatly influenced the CNG content of cassava foods. It was concluded that since CNG can be greatly reduced by suitable processing, it may not be a limiting factor in the utilisation of cassava for food and feed purposes.

Retention of carotenoids in orange-fleshed sweet potato during processing.

Abstract: The retention of carotenoids was studied in the storage roots of ten sweet potato clones possessing different intensities of dark orange-flesh colour in four different processing methods—oven drying, boiling, sun drying and frying. The results indicated that the extent of retention varied with the method of processing. The highest retention was observed in oven drying (total carotenoids 90%–91% and β-carotene 89%–96%) followed by boiling (total carotenoids 85%–90% and β-carotene 84%–90%) and frying (total carotenoids 77%–85% and β-carotene 72%–86%). The lowest retention of total carotenoids (63%–73%) and β-carotene (63%–73%) was recorded in the sun drying method.

Elicitor recognition, signal transduction and inducedresistance in plants

Abstract: The most viable and practical option for the management of plant diseases is disease resistance. However, in most of the crop plants, natural resistance against pathogens is rare. Breeding resistant varieties is a long-term process and the possibility of resistance being broken always exists. Induced resistance exploiting natural defense machinery of plants is indeed an alternative, nonconventional and ecologically friendly approach for plant protection. Its introduction into agricultural practice could minimize the scope of chemical control, thus contributing to the development of sustainable agriculture. Induced resistance can be defined as an increased expression of natural defense mechanisms of plants against various types of pathogens, provoked by a range of factors: pathogens causing hypersensitive necrotic reaction, avirulent or attenuated pathogenic strains, and elicitors of pathogenic origin (glucans, proteins, lipids, etc.). Induced resistance, being based on the expression of latent ge...
