The Plant Regulator Soaking Seeds and its Reflections on Growth and Yield Quality of Wheat
A greenhouse pot experiment was carried out during November 2013 to May 2014. Winter wheat grains (Triticum aestivum L.), cultivars Abu-Ghureb and Cham6 were used to investigate the effect of soaking seeds in 300ppm of benzyl adenine (BA) or daminozide solutions for 6 hours before sowing vegetative, yield components, leaf chlorophylls and some chemical constituents of seeds. BA treatment led to significant increases in tiller number plant-1, chlorophyll b, P, dry gluten, N and protein contents of seeds. It also led to significant decreases in number of leaves plant-1. In addition, the number of tillers plant-1, shoots dry weight plant-1, P, N and protein contents of seeds were increased by daminozide treatment, but this caused a significant decrease in the plant height, number of leaves plant-1 and flag leaf area. Number of grains plant-1, weight of 1000 grains and grains yield were significantly increased by both treatments. Cultivar variability was noted for some tested parameters. The tall, N, P content and protein content of Abu-Ghureb cultivar were higher significantly than Sham6. The case was opposite with number of leaves plant-1, flag leaf area, shoots dry weight plant-1, spike length and grain number plant-1
Investigation of the anti-hyperglycemic and antioxidant effects of wheat bread supplemented with onion peel extract and onion powder in diabetic rats
Aim Onion is one of the commonly cultivated and consumed vegetables rich in nutrients and phytochemicals. Various nutraceuticals are found in the outer fleshy layers and dry peel of onion which usually is treated as a common biowaste. Diabetes mellitus is a leading non communicable disease causing hyperglycemia and increased production of free radicals that potentially disrupts antioxidant enzymatic activity. Considering global consumption of wheat, the present study was designed to evaluate the anti-hyperglycemic and antioxidant effects of wheat bread supplemented with onion peel extract (OPE) or onion powder (OP) on diabetic rats. Methods In this study, ethanolic extract of onion peel and onion bulb were prepared separately. Male Sprague Dawley rats were divided into 6 groups (n = 7). Different regimens of supplemented wheat bread (OPE (1% and 3%) and OP (5% and 7%)) were given to diabetic rats for eight weeks, plain bread was used as the control. Blood glucose level, body weight and activities of SOD, CAT, GPx, GR, GSH and MDA in the liver and kidney tissues were evaluated. Statistical analysis was performed using SPSS Version (25) and Dunnett's multiple comparison test. Results Bread supplemented with 1% and 3% onion peel extract and 7% onion powder significantly reduced blood glucose levels and MDA in the treated rats compared with the control group diabetic rats. Body weight of diabetic rats was reduced for control group, while onion supplemented diet improved the body weight of treated rats. Onion supplementation also brought significant improvement in antioxidant enzyme activities among the treated diabetic rats. Conclusion These findings suggested that onion supplementation is effective in lowering blood glucose and could potentially aid in protecting organs from oxidative stress.Peer reviewe
Proximate and Sensory Analysis of Wheat Bread Supplemented with Onion Powder and Onion Peel Extract
In current era, the agro-waste production is tremendously increasing which strongly influences the stability of the ecosystem and ultimately the human health. Onion is among one of the most commonly consumed vegetables worldwide, but its peel is generally regarded as waste, which is rich in various phytonutrients. Wheat bread is consumed as a staple food by large number of populations hence this study was aimed at improving the nutritional quality of bread by supplementing it with onion peel extract (OPE) and onion powder (OP). A control bread was synthesized using standard formulation while breads supplemented with OPE and OP were prepared by substituting wheat flour with OPE and OP at 1%, 3% and 5%, 7% respectively. Proximate analysis of five types of bread (A, B, C, D, E) presented that addition of onion peel extract significantly (p <0.05) improved the moisture content (21.06-21.79%) of breads while incorporation of onion powder brought significant improvement in fiber (0.24-0.32%), protein (9.80-10.35%) and ash content (1.55-1.94%). Sensory analysis of the breads was done by a semi- trained panel constituting of 7 members. Significant differences were reported among the five treatments for appearance, texture, taste, odor and overall acceptability. Maximum score for all the above- mentioned attributes was obtained by 1% OPE fortified bread while the 7% onion powder fortified bread attained the lowest scores. The sensory attributes of OPE makes it a good flavoring ingredient for baked items.Peer reviewe

Polymethoxyflavones: an updated review on pharmacological properties and underlying molecular mechanisms
ABSTRACTPolymethoxyflavones (PMFs) are dietary bioactive phytochemicals, naturally present in all forms of citrus or plants. For this updated review, the specialized databases of PubMed and Web of Science were researched using keywords such as “polymethoxy flavones,” “pharmacology,” “molecular mechanisms,” “signaling pathways,” and “therapeutic applications.” The most prominent citrus PMFs with proven pharmacological effects are tangeretin, nobiletin, 5′-demethylnobiletin, tetramethyl-o-scutellarein, pentamethoxyflavone, tetramethyl-o-isoscutellarein, and sinensetine. The results of in vivo and in vitro preclinical studies of PMFs have highlighted molecular mechanisms and signaling pathways for anti-inflammatory, anti-cancer, chemopreventive, antidiabetic, anti-obesity, hepatoprotective and neuroprotective effects in neurodegenerative diseases. The results of the studies support the traditional effects of PMFs and therefore it is necessary that these natural compounds be further investigated in clinical trials. PMFs should be designed and formulated in nanoformulations that increase their bioavailability and transport them precisely to the target in order to increase their therapeutic effects
Utilization of biomaterials to develop the biodegradable food packaging
ABSTRACTFood packaging material is the primary element of the food industry; therefore, its consideration to sustain food quality and food safety is crucial. Several food-grade materials have been utilized for packaging food commodities for a long time. Still, these materials negatively influence safety, shelf life, texture, quality, and flavors of the food commodities. Concurrently, biotechnology introduces various techniques to produce several edible food packaging materials i.e. polysaccharides and protein-based films, intelligent and active packaging, which can preserve the food for a long period and inhibit the entry of biotic and abiotic components into the food. Various materials i.e. nisin, chitosan, cactus/mucilage, and bacterial nanocellulose, are being utilized to produce various kinds of edible packaging, including films, coatings, foams, with various kinds of edible active and intelligent packaging characteristics by biotechnological tools. The packaging material prepared by biotechnological applications is widely adopted and utilized in various food processing and preservation industries due to its higher safety levels and more nutritional components for consumption. The edible packaging material is currently utilized only for solid and semisolid processed products. However, there is an urgency to develop edible packaging material for liquid commodities such as products of the dairy and beverages industry by utilizing biotechnological techniques
