Background: ATR-FTIR spectroscopy is proved to be a simple, reliable, rapid and easy-to-use technique to assess the groundnut seed quality. Groundnut seeds are highly sensitive to deterioration mainly due to their chemical composition and moisture content. The high oil content and fatty acids of groundnut seeds reduces the seed viability well in advance due to lipid peroxidation process, which is the most frequent cause of seed ageing. As a result, not only lipid peroxidation, but also a series of reactions that produce toxic products occur. Methods: Eleven groundnut seed lots were tested for their seed germination potential as well as the oil quality parameters, ATR-FTIR analysis, antioxidant enzyme activities and physiological seed quality parameters. Result: The results indicated that the FTIR spectra of the seed lots having higher germination ( greater than 70%) exhibited deviations at different wave numbers within the range of 4000-400 cm-1 when compared with seed lots having lower germination ( less than 70%). The peak intensity was found to follow an increasing trend to a decrease in germination percentage of the seed lots. The seeds lose its viability, the activity of antioxidant enzyme decreases leading to an alteration in free fatty acid, acid value, saponification value, iodine value and peroxide value. Finally, the study concluded that the changes in seed germination from 92 to 12 per cent and their corresponding enzyme activity are closely correlated with FTIR spectral data. Hence, ATR FTIR may be used as a tool to predict the quality of the groundnut seeds during storage.

“…Muniyappan used nerium biodiesel and its mixes to study an LHR engine's performance and emission characteristics. 77 At full load, the BTE of the coated engine is 3.8% more than the BTE of the uncoated engine. Except for NO x emissions at all loads, the different emissions for the coated engine with methyl ester of nerium oil (MEON) are lower.…”

Depending on the heat content and compression ignition (CI) engine combustion, biodiesel is a viable substitute fuel. Biodiesel is an oxygenated, safe, sulfur-free, biodegradable, and renewable fuel. It may be utilized in CI engines in any combination with diesel fuel without requiring the engine to be significantly modified. Many research studies have been made with several biodiesels as diesel substitutes, including Pongamia pinnata, Jatropha curcas, Mangifera indica, and Madhuca longifolia. The topic of the current review is the potential of renewable fuels to outperform diesel fuel in terms of performance, combustion, and emission characteristics. In the present study, CI engines are fueled with biodiesels made from Man. indica, Mad. longifolia, and pongamia seed oil. Adopting low heat rejection (LHR) mode CI engines and adding an antioxidant agent in addition to the biodiesel blends may resolve the issue of these biodiesels’ poorer performance and increased NO emission. Both these additions may provide positive approaches in both performance and emission.

than 10 w. b. 6, 7 , it was susceptible to mold development and toxin production 8. The peanut drying process can be performed based on many drying methods, such as solar radiation, hot air drying, microwave and radio frequency heating etc. 9. But the most commonly used methods were solar radiation and hot air drying 9. Drying by sun usually took a long time and was affected by weather. Hot air drying process can be performed by traditional bin dryers or semitrailers with heated air passing through the bed of peanuts 10. Studies on peanut drying by hot air mainly focused on drying parameters 7 , the uniformity of peanut drying 11 , the effective diffusion coefficient and the main thermodynamic properties 12 , the mathematical model of thin layer drying 12, 13 , the non-isothermal drying models 14. In addition to the above researches on peanut drying, there were also some studies on the quality of raw peanut Abstract: Peanuts are usually with high moisture after harvest and must be dried to prevent mildew. Hot air drying is the most commonly used method for peanut drying. The purpose of this study was to evaluate the drying temperatures on the peanut qualities. In this paper, fresh peanuts were dried with solar radiation (control group) and hot air at 35-60℃ until the moisture content of peanut reduced below 10%. The physical (texture, damaged percentage of red testa and breakage percentage of peanut kernel), physiological (germination) and biochemical (the contents of vitamin E and aflatoxin B 1 ; acidity values, iodine values, peroxide values and fatty acid composition of peanut oil; solubility, emulsifying, foaming, water-holding capacity and oil-binding capacity of peanut protein) properties of peanut kernel were determined under different drying conditions (solar radiation, 35℃, 40℃, 45℃, 50℃, 55℃, 60℃). The results showed that hot air temperatures had obvious influences on peanut qualities. The damaged percentage of red testa and breakage percentage of peanut kernel increased remarkably when the drying temperatures were above 45℃. Meanwhile, when drying temperatures were more than 45℃, the acid value and peroxide value of the extracted oil increased significantly. Furthermore, some properties exhibited prominent changes when the temperatures were higher than 50℃, such as hardness, brittleness, germination percentage, and the Vitamin E content of peanut kernel. In addition, the research results revealed that hot air can increase hydrophobicity of peanut protein and affect the functional properties of peanut protein. Therefore, it could be concluded that peanut should be dried by hot air below 45℃ for quality maintenance. It also provided reference to choose suitable drying temperatures based on the final use of peanut.
