Air-frying is an innovative technique for food frying that uses hot air circulation to prepare healthy products. The objectives of this study were to establish simplified models to reflect the efficacy of the air frying process at varying temperatures and times on the quality attributes of falafel, and to optimize the frying conditions for producing air-fried falafel. Moisture content, color, fat content, hardness, and sensory evaluation of the fried falafel were analyzed under varied temperatures (140 °C, 170 °C, and 200 °C) and time periods (5 min, 10 min, and 15 min). Statistical analysis was then applied to obtain the best fit model that can describe the properties of fried falafel. Results indicated that moisture content, fat content, and L*-value of air-fried falafel were adversely related to the frying temperature and time, but the hardness and ΔE of fried falafel were increased as the frying temperature and time increased. Moreover, an increase followed by a decrease was shown for the appearance, aroma, crispness, taste, and overall preference scores with the increase in frying temperature and time. The regression analysis showed that the proposed models could be properly used for predicting the properties of the fried falafel. In addition, the overlaid plots resulted in the optimum frying temperature of 178.8 °C and time of 11.1 min. Interestingly, the fat content of the air-fried falafel reduced by 45% at optimal frying conditions compared with that for the deep-fat fried one at 180 °C for 7 min (control). In comparison, the air-fried falafel was lower in fat content, higher in hardness with more acceptable appearance and crispness scores than deep-fat fried falafel. Such information could be beneficial to the manufacturers of the falafel to produce an optimal and healthy product.

Infectious diarrhea is endemic in most developing countries. We aimed to investigate the protozoan, viral, and bacterial causes of acute diarrhea in Taif, Saudi Arabia. A cross-sectional prospective 1-year study was conducted on 163 diarrheal patients of various ages. Stool samples were collected, 1 per patient, and tested for 3 protozoa, 3 viruses, and 9 bacteria with the Luminex Gastrointestinal Pathogen Panel. Overall, 53.4% (87/163) of samples were positives (20.8% protozoa, 19.6% viruses, 2.8% bacteria, and 9.8% mixed). Rotavirus (19.6%), Giardia duodenalis (16.5%), and Cryptosporidium spp. (8.5%) were the mostly detected pathogens. Adenovirus 40/41 (4.2%), Salmonella (3%), Shiga toxin-producing Escherichia coli (3%), and Entamoeba histolytica (2.4%) were also detected. Norovirus GI/II, Vibrio cholerae, Yersinia enterocolitica, and Clostridium difficile toxin A/B were not detected in any patients. All pathogens were involved in coinfections except E. histolytica. Giardia (5.5%) and rotavirus (3%) were the most commonly detected in co-infections. Enterotoxigenic E. coli (2.4%), Campylobacter spp. (2.4%), E. coli 0157 (1.8%), and Shigella spp. (1.2%) were detected in patients only as co-infections. Infections were more in children 0-4 years, less in adults 40 years, with statistically significant differences in risk across age groups observed with rotavirus (P<0.001), Giardia (P=0.006), and Cryptosporidium (P=0.036) infections. Lastly, infections were not significantly more in the spring. This report demonstrates the high burden of various enteropathogens in the setting. Further studies are needed to define the impact of these findings on the clinical course of the disease.

Wheat is the leading staple food in the world, particularly in developing countries, which lacks a mechanism of zinc absorption; when compared to pulses, more attention is consequently important to be given to the wheat crop. Micronutrient deficiencies and especially zinc deficiency influences one-third of the world population. In addition to this, it is also essential for the growth and development of plants and animals. A pot and field experiment was conducted to check the effect of foliar application of zinc sulphate on three different wheat varieties at the same time. Treatment consisted of three zinc levels (control, 4%, 6%) in the form of zinc sulphate (21% Zn) applications were applied on various wheat varieties (Zincol, Fakher-e-Bhakkar, Faisalabad-2008) at different growth stages (tillering, booting and heading). Different zinc levels showed different results on wheat varieties in both experiments. Results revealed that var. Fakher-e-Bhakkar was best at 6% zinc application for more plant height, the number of spikelets, spike length, 100-grain weight, biological and grain yield per plant as compared to other varieties and treatments. Antioxidants and nutritional quality (protein, gluten, starch and zinc contents) showed variable behavior both on wheat varieties and zinc application. It is concluded that Fakher-e-Bhakkar was found to be the most responsive cultivar at 6% zinc application for improvement in growth, yield-related traits and nutritional quality. So it is recommended for achieving maximum yield and yield components and grain zinc contents of wheat under agro-climatic conditions of Layyah, Punjab-Pakistan.

The use of organic amendments is seen to be a promising method for enhancing crop productivity and soil health. Therefore, this study was performed for two consecutive years (2019 and 2020) to determine the effects of organic biochar (BC), sugar industry press mud (MUD), and poultry manure (PM) combined with inorganic amendments on the yield and nutritional quality of forage sorghum at the College of Agriculture, Bahauddin Zakariya University, Bahadur sub-campus, Layyah, Pakistan. The treatments were comprised of the following: control (no inorganic or organic amendments added); recommended dose of NPK (59:72:30 kg ha⁻¹); half dose of NPK (29.5:36:15 kg ha⁻¹); recommended dose of poultry manure (PM) at 5 t ha⁻¹; recommended dose of press mud (MUD) at 40 t ha⁻¹; recommended dose of biochar (BC) at 11 t ha⁻¹; BC + half NPK; MUD + half NPK; PM + half NPK; PM + BC + half NPK; PM + MUD + half NPK; BC + MUD + half NPK; PM + BC + MUD + half NPK. The treatments were carried out in a triplicate randomized complete block design. Results revealed that combined application of PM + BC + MUD + 1/2 NPK significantly enhanced the plant height (201 cm), number of leaves (17), stem diameter (18 mm), stem dry weight (201.7 g), leaf dry weight (30.4 g), leaf area (184.3 cm²), green forage yield (31.8 Mg ha⁻¹), and dry biomass yield (12.7 Mg ha⁻¹) compared with the control treatment. Forage quality traits, including crude protein (CP), brix percentage, acid detergent fiber (ADF), and acid detergent lignin (ADL), showed maximum value with the combined application of PM + BC + MUD + 1/2 NPK. ADF and ADL are linked with lower digestibility; therefore, it was concluded that the combined application of PM + BC + MUD + 1/2 NPK can improve the productivity, dry biomass yield, and CP of sorghum, but reduces the digestibility under semi-arid conditions, such as those in Central Pakistan.
