Yavatmal, Maharashtra, India) were studied to assess the impact of mining activities on the surroundings. Out of 25 water samples, 7 samples contained slightly higher concentrations of measured contaminants and fall into the category of marginally safe sources for human consumption as per the standard BIS classification. However, some sources are found to be approaching the maximum permissible limits. Soil samples indicate adverse influence of mining activities on the soil quality. Overburden sample showed high acidic pH and exceptionally high TDS, chloride, nitrate, nitrite, sulphate, magnesium, iron, nickel, copper, manganese and zinc, which contribute extensively to the contamination of surface waters. <br/> <br/>Page(s): 777-784 http://nopr.niscair.res.in/handle/123456789/1317 Title: Optimization of restaurant waste oil methyl ester yield <br/> <br/>Authors: Math, M C; Irfan, G <br/> <br/>Abstract: Biodiesel may be cost effective if produced from low cost oils (animal fats, restaurant waste oil and frying oil), which, however, contain high amount of free fatty acids (FFA). In the present study, different amounts of methanol (20, 25, 30, 35, 40 and 45%), catalyst concentrations (0.3, 0.5, 0.7, 1.0 and 1.5 % NaOH), reaction temperature (30, 45 and 55°C) and different reaction times (60, 90 and 120 min) were selected for transesterification of restaurant waste oil in order to optimize experimental conditions for maximum biodiesel yield. Methyl ester yield (65.50-85.50 %) in the laboratory scale biodiesel reactor was obtained maximum (85.50 %) at the optimized process parameters such as methanol (35% by vol), NaOH (0.3 g), reaction temperature (55°C) and reaction time (90 min). <br/> <br/>Page(s): 772-776 http://nopr.niscair.res.in/handle/123456789/1316 Title: Modelling of thin layer drying kinetics of sour cherry in a solar dryer and under open sun <br/> <br/>Authors: Akpinar, E Kavak; Bicer, Y <br/> <br/>Abstract: Drying kinetics of sour cheery is investigated in solar dryer with forced convection and under open Sun with natural convection. Drying data were fitted to different mathematical models, whose performance was investigated by comparing coefficient (R), reduced chi-square (Dz) and root mean square error (RMSE) between the observed and predicted moisture ratios. Among these models, drying model developed by Midilli and Kucuk model showed good agreement with the data obtained from the experiments in the solar dryer with forced convection drying mode. Logarithmic model has shown a better fit to the experimental sour cherries data for open sun drying with natural convection mode than the other models. <br/> <br/>Page(s): 764-771 http://nopr.niscair.res.in/handle/123456789/1315 Title: Physical and sensory characteristics of low fat dairy dessert (Rasogolla) fortified with natural source of β- carotene <br/> <br/>Authors: Bandyopadhyay, Mahuya; Chakraborty, Runu; Raychaudhuri, Utpal <br/> <br/>Abstract: Rasogolla (a white color ping pong like juicy ball prepared by boiling mashed fresh cheese or cottage cheese ball in concentrated sugar syrup) fortified with carrot paste (10%, 20%, 30%, 40% and 50% levels named as sample CRA, CRB, CRC, CRD and CRE respectively), were developed and then compared to conventional Rasogolla taken as control by both sensory and instrumental analysis. All 5-type carrot Rasogolla were similar to control in respect of moisture, sucrose and ash but differed in fat and protein content. Textures of carrot Rasogolla were similar to control in terms of elasticity and cohesiveness. A trained panel found that carrot Rasogolla (CRA, CRB, and CRC) was more acceptable than CRD, CRE or control Rasogolla. Carrot Rasogolla CRC possesses highest β-carotene level. Rasogolla fortified with carrot could be a valuable addition to indigenous dairy products. <br/> <br/>Page(s): 757-763
