The effect of depigmentation on colour, nutritional, anti-nutritional, cooking and textural qualities of pasta prepared from pearl millet was studied. Depigmentation was achieved by soaking pearl millet grains in hydrochloric acid of 0.2 N for 18 h at 28–32°C fol1owed by washing, blanching (98°C for 30 sec) and tray drying (50°C). Pasta prepared from 100% wheat semolina (WS), 100% native pearl millet flour (PMF) and blend (50 : 50) of wheat semolina and native pearl millet flour (WS : PMF) were compared with pasta prepared from blend (50 : 50) of wheat semolina and depigmented pearl millet flour (WS : DPMF). It was observed that depigmentation significantly improved the colour of pasta and was very close to 100% wheat semolina pasta. Results also demonstrated that the contents of fat, protein and ash of pasta made from PMF (100%), WS : PMF (50 : 50) and WS : DPMF (50 : 50) were higher than that of pasta prepared using WS (100%). Reduction in phytic acid (5.56%) and trypsin inhibitor activity (5.27%) was observed with depigmentation in the WS : DPMF (50 : 50) pasta compared to WS : PMF (50 : 50) pasta. However, cooking and textural properties of pasta were not affected by depigmentation. Overall results of the study suggested that depigmentation technique was effective for formulation of acceptable pearl millet products.Keywords

A nationwide survey is being conducted for mapping uranium content in drinking water sources across India, in association with local educational and research institutions. For this, an optimum grid size of 6 × 6 sq. km was selected based on the international practices for geochemical mapping. About 55,554 surface as well as groundwater samples, used for drinking purpose, were collected covering approximately 1.2 × 106 sq. km. Light emitting diode-based fluorimeter having wide dynamic range and 0.2 μg l–1 lower detection limit was used for direct measurement of uranium content in the water samples. Uranium was detected in 83.6% of all the collected water samples. The geometric mean of uranium concentration in surface and groundwater samples was found to be 0.8 μg l–1 (range: ≤0.2–22 μg l–1) and 2.1 μg l–1 (range: ≤0.2–4918 μg l–1) respectively. Out of 12 water quality parameters measured to understand the geochemical processes governing uranium content in water sources, eight were found to exceed the acceptable limits set by the Bureau of Indian Standards for drinking water. The parameters sulphate, chloride, nitrate, fluoride, total dissolved solids, alkalinity and hardness exceeded their limits by 4.2%, 12.9%, 14%, 20.5%, 34.3%, 45% and 51.6% respectively. Uranium content in 98% of groundwater samples was found to be less than the national limit set by the Atomic Energy Regulatory Board for radiological safety. Dissolved uranium content in groundwater samples showed an upward trend with total dissolved solids and depth of water sources. No surface water samples exceeded the prescribed regulatory limit.Keywords

The Indian nuclear programme stresses upon the indigenous development of technologies and self-reliance. The article presents an overview of nuclear fuel fabrication for research and power reactors. In the recent past, stress is on the automation of various manufacturing and inspection processes. This results in consistency and repeatability in quality. A wide variety of nuclear fuels have been used in the research reactors and this provides options for the future. The fabrication of fuel for the research reactors is done at the Atomic Fuels Division, Bhabha Atomic Research Centre, Trombay, and the Nuclear Fuel Complex, Hyderabad has the mandate to supply fuel bundles to various power reactors. This article gives an overview of developments over the years and the present status. It also covers fuel manufacturing for a variety of research and power reactors in the country.Full Text
