Ltd., Sudan. He has been listed in the book WHO’S WHO in the World 2005, 2006, 2007 and 2010. He has published over 300 papers in peer-reviewed journals, 200 review articles, 15 books and 150 chapters in books.
Abstract:
There is strong scientific evidence that the average temperature of the earth’s surface is rising and this may be attribute to increased concentration of carbon dioxide (CO2), and other greenhouse gases (GHGs) in the atmosphere as released by burning fossil fuels. One of the chief sources of greenhouse gases is burning of fossil fuels. Biogas from biomass appears to have potential as an alternative energy source, which is potentially rich in biomass resources. In the present study, current literature is reviewed regarding the ecological, social, cultural and economic impacts of biogas technology. In this communication an attempt has been made to give an overview of present and future use of biomass as an industrial feedstock for production of fuels, chemicals and other materials. However, to be truly competitive in an open market situation, higher value products are required.

Title: Ultrasonic assisted extraction of phenolic compounds from wood apple (Limonia acidissima L.) using Ultra-High-Performance Liquid Chromatography (UHPLC)
Biography:
Biography: Prof Aradhita Barmanray (M.Sc, PhD), Former Head of Dept. of Food Technology GJUST Hisar, Haryana, India, is having 26 years of Teaching and Research experiences. Her area of expertise is Post harvest processing and value addition of fruits and vegetables. She has published 75 Research Papers in Journal of National and International repute. 6 Ph.D, around 90 M.Sc and 30 M.Tech degrees have already been awarded under her supervision.
Abstract:
Wood apple (Limonia acidissima L.) is an underutilised fruit which is native to India and Sri Lanka, belongs to the Rutaceae family, with number of medicinal and nutritional benefits. The fruit contain numerous antioxidant, antimicrobial, and anti-inflammatory properties. This study was aimed to optimise the ultrasonic extraction conditions using Response Surface Methodology (RSM), varying the independent factors such as solvent concentration of methanol (50-100 %), ultrasonic temperature (30-50 oC), sonication duration (20-40 min), and ultrasonic frequency (25-45 kHz). The response factors of extractions selected for extraction include phenolic yield, total phenolic content (TPC), and DPPHsc activity. The optimal conditions observed for ultrasonic extraction were solvent concentration (61.5 % methanol), temperature (50 oC), sonication duration (40 min), and ultrasonic frequency (25 kHz). Under these specific optimal conditions, the extraction yield of phenols was found 25.81%, TPC of 224.36 g GAE/g, and DPPHsc activity of 93.49%. The model's significance was suggested to be at a 95% confidence level, and all three responses were statistically acceptable based on significant regression (p<0.005) and lack of fit (p<0.001). Further, ultra-high-performance liquid chromatography (UHPLC) analysis of phenolic compounds from methanolic extract of wood apple fruit pulp revealed a significant amount of gallic acid, catechin, caffeic acid, syringic acid, vanillic acid, and quercetin.

Saima Majeed
The Islamia University Bahawalpur, Pakistan
Title: Health Risk Assessment of Multiple Mycotoxins by Maize Consumption in Pakistan
Biography:
Dr. Saima Majeed obtained a Ph.D. degree in Biotechnology from Pakistan Institute for Engineering and Applied Sciences, Islamabad, Pakistan with distinction. She has won Ph.D. indigenous & IRSIP scholarships from HEC. She has done Pre-Doc research in bioanalysis lab at the University of Ghent, Belgium. She has supervised 5 MSc., 6 MPhil. & 01 PhDs. She has published 10 research articles. She has won an IFS funded research grant (I-3-E-6286-1) entitled “Health Risk Assessment of Multiple Mycotoxins by Wheat Consumption in Pakistan.” She is doing research projects on food contaminants under the fields of analytical chemistry, mycology and molecular biology.
Abstract:
Statement of the Problem: Mycotoxins are toxic secondary fungal metabolites, which pose a serious health risk to both animals and humans. Maize can be consumed as a staple food in Pakistan and in most part of the world. Maize crop is especially susceptible to mold infection and toxic mycotoxins. Knowing the level of contamination can help in evaluating and managing the risks associated with these contaminants. The available data in Pakistan is limited to a few mycotoxins and lacks the health risk evaluation. Methodology & Theoretical Orientation: This study was conducted to check the health risk assessment of mycotoxins dietary exposure in six regions (Punjab, Sindh, Baluchistan, Khyber-Pakhtunkhwa, Azad jamu Kashmir, Gilgit Baltistan) of Pakistan through the maize consumption by using a confirmatory validated LC-MS/MS method for analysis. A total 22 mycotoxins were analyzed in maize samples (n=152). Findings: The estimated average maize consumption in adult population of these six regions was in the range of 0.17±0.19 -2.73±1.92g/kg body weight per day, while, in children population was from 0.25±0.26 to 2.39±1.60 g/kg body weight per day. The average dietary exposure of AFB1 in adult population of all the six regions was between 0.323 to 72.44 ng/kg body weight per day and in children from 0.394 to 57.85ng/kg body weight per day. The estimated margin of exposure due to the exposure of AFB1 by the consumption of maize in adult was from 2.34 to 526.31, while, in children from 2.93 to 431.03. The AFB1 cancer risk values in adults of all the six regions were from 0.036 to 9.74 cases/year/100,000 of population, while, in children population the values lie between 0.057 to 2.03 cancer cases/year/100,000 population. Conclusion & Significance: This research will provide new perspectives for the management and planning of food contaminants for the population of Pakistan.
