Wheat (Triticum aestivum L.) is the basic ingredient of cookies formulation and its specific or consistent quality (soft wheat) is required for cookie making. In Pakistan, wheat flour is produced from a mixture of wheat varieties called mixed wheat flour (MWF) leads to unavailability of specific wheat variety suitable for specific product. However, this flour has inconsistent quality and subsequently affects product quality significantly. Present study has been aimed to evaluate the impact of various treatments on MWF. Results showed a wide range of TW and TKW as 67.00-81.00 kg hl-1 and 32.82-48.70g, respectively. Wheat varieties exhibited moisture (8.50-10.78%), ash (0.33-0.83%), fat (1.36-1.49%), fiber (0.38-0.52%), protein (9.85-13.75%) and NFE (72.82-79.58%) content. Mineral composition varied as 2.20- 2.64, 20.25-28.45, 2.12-4.71, 1.24-2.31, 0.54-0.85 and 0.45-0.57 mg/100g for Na, Ca, Fe, Zn, Mn and Cu content, respectively. Moreover, wheat varieties indicated wet gluten, dry gluten, starch and DS as 24.68-36.40, 7.12-11.84, 68.88-72.73 and 6.28-10.97%, respectively. SDSsed. and AWRC were reckoned as 18.20-30.50 ml and 43.91-66.85%, respectively. Moreover, WSRC, SOCSRC, SUCSRC and LASRC values varied widely as 50.83-69.64%, 56.66- 82.03%, 75.79-106.97% and 79.43-121.20%, respectively. Rheological properties were found i.e. WA (51.00-56.00%), DDT (1.20-4.20 min), dough stability (2.90-18.20 min), DoS (85.00- 174.00 BU) and FQN (48.00-200.00). Pasting properties indicated variability from 65.25 to 67.80oC (PaT), 3.22 to 6.00 min (PT), 1330 to 1784 cP (PV), 645 to 1002 cP (TV), 1799 to 2565 cP (FV) 685 to 782 cP (BV) and 1154 to 1563 (SV). Physical analyses of cookies made from wheat varieties revealed 39.38-45.86 spread factor and 2.17-3.76 kg hardness. Sensory evaluation indicated that cookies made with AARI-11 were highly acceptable and also, it was selected as best variety for cookie making. In addition, different treatments were also applied and cookies made with different treatments portrayed spread factor (39.68-60.96) and hardness (0.86-3.55 kg). Cookies color determined in terms of L*, a* and b* values as 64.65-74.84, 1.22-3.75 and 31.10-35.44, respectively. Cookies revealed moisture (1.50-3.68%), ash (0.333- 0.547%), fat (17.70-23.66%), fiber (0.083-0.167%), protein (5.41-6.56%) and NFE content (66.76-72.40%). Across treatments, addition of CMS (15%) produced largest spread, protease (400 mg) had highest overall acceptability. Correlation studies underline the importance of SRC values and SDS-sed. volume as major predictors of cookie making quality in addition to other physicochemical characteristics of flour.

شعبہ مالیات کے امین
افسوس ہے کہ ۱۴؍ ستمبر کو دارالعلوم ندوۃ العلماء کے شعبہ مالیات کے امین و معتمد، دنیوی زندگی کی امانت کو ادا کرنے کے بعد اپنے مالک حقیقی سے جاملے، وہ استاذ الاساتذہ محمد سمیع صدیقی مرحوم کے صاحبزادے تھے جن کا تعلق ندوے سے مکانی ہی نہیں روحانی بھی ہمیشہ رہا، وہ ندوہ اور خصوصاً مولانا سید ابوالحسن علی ندویؒ کے عاشقوں میں تھے اور خود ایک باکمال اہل قلم تھے، ایسے باکمال کا اٹھ جانا بڑا سانحہ ہے، اﷲتعالیٰ ان کے حسنات کو قبول فرما کر بلند درجات سے نوازے۔ ( عمیر الصدیق دریابادی ندوی ، ستمبر ۲۰۱۰ء)

 

معاملة المخطئين والجاهلين في ضوء السيرة النبوية العطرة

Allah Almighty had created man with the instinct to choose between good and evil. It is nature that being a human to be indulged in some activity unconsciously and then to realize and feel sorry for the crime committed. To err is human and to forgive Devine. So sins should not be treated as a single entity for there are of various types, ranging from the small mild ones to the big severe ones, thus dividing people who commit them accordingly. When our father and mother, ate from the forbidden tree, which was wrong, they realized it there and then, and instantly felt pain and remorse and abstained from it and declared repentance with humility and knocked the door of Allah for mercy and forgiveness. Allah the almighty heard their prayers and embraced them in his mercy and forgave their sin, for he is most gracious, and most merciful. Similarly our prophet has set an ideal for treating the sinners, he did not turn his face away from them nor did he declare abandoning them or excommunicating them or even counting them as dirt that should be avoided or looked down upon. He treated them with an open heart and with utmost compassion, sympathy and tolerance, and took them by the hand to the righteous path, his sympathy was always present, a sun that never sets. This article is basically to deal with prophetic examples and virtual self how the Prophet Muhammad (ﷺ) treated the sinners and ignorant. It is suggested that the public and the rulers should be made aware about the with deal to able be would they that so, (صلى الله عليه وسلم) Prophet Holy of teaching sinner and ignorant in an effective manners by following the teaching of.

Human Health Risks Associated With Heavy Metal-Contaminated Soil and Food Plants Irrigated With Wastewater

Long-term wastewater irrigation is not only a way of contaminations of soil with heavy metals (HMs) but also accumulates HMs in food crops. Samples of both soil and vegetables were collected from wastewater irrigated sites of Peshawar, Pakistan in winter and summer seasons for analysis of HMs concentrations in them and to investigate the health risk of associated with HMs contaminated vegetable. The mean concentrations (mg/kg dry weight) of selected HMs like Cu, Pb, Cd, Ni, Zn, Mn, Cu, Co and Hg in soil irrigated with wastewater in winter, summer seasons and preference soil were 56.9, 37.01 and 13, 61.28, 62.1 and 10.4, 7.68, 8.9 and 1.2, 100.78, 106.64 and 23, 159.55, 193.4 and 12, 341.33, 387.7 and 14, 40.54, 41.1 and 24, 61.64, 88.2 and 15 and 459.455, 93.1 and 23 mg/kg, respectively Similarly the mean concentrations (mg/kg dry weight) of studied HMs like Cu, Pb, Cd, Ni, Zn, Co, Cr, Hg, Mn and Fe in the vegetables grown in wastewater irrigated soil in winter, summer season and preference soil were 26.8, 24.69 and 13 63.7, 44.7 and 11.45, 8.3, 13.98 and 3, 38.31, 34.and 32.4, 64.1.128.1, and 33, 25, 21.77 and 11, 20.7, 57.45 and 31.68, 421.76, 497.55 and 100.01, 41.1, 32.26 and 17 and 576.85, 632.3 and 300 respectively. The concentrations of studied HMs were significantly higher in both soil and vegetables samples collected in summer season than their concentrations in winter’s samples. The concentrations of Pb, Cd, Ni and Cr exceeded their respective permissible limits set by WHO/FAO. Transfer factor (TF) values of selected HMs from soil to vegetables and the target hazard quotients (THQs) to the possible health risks to local population through the food chain were also calculated. The mean values of root transfer factor (RCFs) ranged from 0.3-1.4, 0.2-1.4, 0.4-3.7, 0.4-1.1, 0.3-0.6, 0.004-0.18, 1-1.8, 0.12-1.5 and 0.4-1.08 for Pb, Cu, Cd, Ni, Zn, Mn, Co, Cr and Hg, respectively in vegetables of study area.. Similarly, values of shoot transfer (SCFs) for Pb, Cu, Cd, Ni, Zn, Mn, Co, Cr and Hg ranged from 0.2-1.4, 0.2-4, 0.3-4.7, 0.2-0.8, 0.47-2.46, 0.02-0.45, 0-1.2, 0.34-2.2 and 0.5- 2.01, respectively in the samples of vegetables. Values of fruit transfer (FCFs) were 0.3- 1.1, 0.2-2.4, 0.8-5.7, 0.2-0.6, 0.31-0.69, 0.002-0.14, 0.4-1.6, 0.3-1.4 and 0.6-0.8 for Pb, Cu, Cd, Ni, Zn, Mn, Co, Cr and Hg, respectively. The dietary intake of metals (DIM) values of Pb, Cd, Ni, Zn, Mn, Cr and Cu by children were ranged from 0.001-0.019, 0.001-0.005, 0.01-0.02, 0.013-0.038, 0.01-0.02, 0.003-0.018, 0.001-0.011, respectively. Similarly the values of DIM for Pb, Cd, Ni, Zn, Mn, Cr and Cu by adults via consumption of vegetables were 0.01-0.023, 0.002-0.006, 0.001-0.03, 0.014-0.042, 0- 0.13, 0.002-0.032 and 0.001-0.013, respectively. The DIM values of Pb and Cd were significantly (p<0.05) higher as compared to respective reference dose (RfD). However, the DIM values of Zn, Cu and Mn were significantly (p<0.05) lower than their respective RfD. The THQ of Pb, Cd, Ni, Zn, Mn, Cr and Cu ranged from 0.668-5.055, 1.362-5.609, 0.36-1.23, 0.044-0.126, 0.08-3.46, 0.002-0.019 and 0.025-0.281, respectively for children. Similarly, the THQ ranged from 0.744-5.586, 1.517-6.248, 0.049-0.119, 0.12- 3.86, 0.002-0.021 and 0.028-0.313 due to Pb, Cd, Ni, Zn, Mn, Cr and Cu, respectively for adults. Greenhouse pot experiments using spinach (Spinacia oleracea) coriander (Coriandrum saivum), purslane (Portulaca oleracea) as representative vegetables were conducted to assess the up take pattern of three different doses of Cd, Pb, Zn, Cd/Pb, Cd/Zn and Pb/Zn The highest dose of Cd, Pb and Zn in single form and in mixture (Cd/Pb, Cd/Zn and Pb/Zn) significantly reduced the growth S. oleracea, C. saivum and P. oleracea seedlings. Similarly, in case of full grown plants of S. oleracea and C. saivum the highest doses of Cd, Pb, Zn, Cd/Pb, Cd/Zn and Pb/Zn reduced the growth In case of all S. oleracea, C. saivum and P. oleracea seedlings the concentrations of Cd, Pb and Zn were positively correlated with their concentrations in soil. The mixture of HMs such as Cd/Pb, Cd/Zn and Pb/Zn the metals behaved antagonistically, which were reflected in the growth parameters of selected plants. In case of full grown plants of S. oleracea and C. saivum the Cd, Pb and Zn concentrations in soil and roots of plants were positively correlated. Similarly, the concentrations of Cd, Pb and Zn in the root and shoot of full grown plants of S. oleracea and C. saivum were positively correlated. Total protein content, fiber and moisture contents of S. oleracea, C. saivum significantly reduced with increasing concentrations of Cd, Pb and Zn alone and also their mixture (Cd/Pb, Cd/Zn and Pb/Zn) in plant tissue. The impacts of mixture of Cd, Pb and Zn on total protein, fiber and moisture content were more sever than the impacts of individual Cd, Pb and Zn but less than the sum of impacts of individual HMs. Similarly, the increasing concentrations of selected HMs reduced the up take of Na, K, Ca, Fe, Mg, Mn and Cu by S. oleracea and C. saivum. It was concluded from this study that soils of Peshawar are rich with HMs because of wastewater irrigation. The plants grown in these soils contaminated with HMs. The HMs adversely impacted the growth parameters of plants, change the up take of important metals by plants and reduced moisture contents, total protein and fiber. The consumption of vegetables in the wastewater irrigated areas in a Peshawar causes health risks to the residents.
