Meat products are highly perishable and prone to deterioration, which poses potential health hazards. This research aims to assess the efficacy of encapsulated oregano essential oil (EOEO) as a natural preservative agent to maintain the chemical and microbiological quality of beef burgers during refrigerated storage. Hydrodistillation was used to e...

This experiment was carried out during two successive seasons (2020/2021and 2021/2022) at the Research and Production Station of the National Research Centre, El-Nubaria location, Governorate of El-Behera, Egypt. It was conducted to evaluate the response of coriander plants to different levels of tryptophan (0, 200, 400 and 600 ppm). All concentrat...

Due to the damaging effects of root-knot nematodes on crops and the dangerous effects of chemical nematicides on both people and the environment in Egypt, the purpose of this study was to assess the power of polysaccharides and polyphenol extracts as well as their nano-forms from marine algae (Laurencia papillosa and Dilophys fasciola) used as eco-...

This study aimed to investigate the potential use of okra and psyllium mucilage as co-carrier wall materials with whey protein and gum Arabic polymers for encapsulation of fenugreek oil to mask its undesirable flavor and promote their health benefits. Particle size, zeta potential, encapsulation efficiency, morphological properties and fatty acid p...

People are becoming increasingly concerned about the environmental issues that arise due to the excessive usage of plastic and are starting to search for alternative biodegradable materials for food packaging. So, in the present work, biodegradable plastic films were prepared using pectin and polyvinyl alcohol (PVA) composites at the levels 1:2, 1:...

Root-knot nematode is one of the major problems that face the agricultural production of several vegetable crops. Chemical nematicides have been banned because of their healthy and environmental undesirable attributes. So, this study aimed to evaluate the potential use of sweet annie (Artimisia annua) and garden cress (Lepidium sativum) as green ro...

In this study, nano and fermented-nano powders of wheat and rice by-products were prepared by superfine grinding of raw and solid-state fermented materials. Effects of fermentation and superfine grinding on phytochemical content, phenolic acids profile as well as antioxidant and anticancer activity were investigated. The results revealed that, phen...

Introduction. Producing new maize cultivars in areas with limited water resources is the main task of plant breeders. However, there is little information regarding their technological characteristics and industrial potential. Besides, snacks have gained worldwide acceptability and become part of modern food culture, especially among young people a...

Background: Drought tolerance and grain quality are the main challenges in maize cultivation due to climatic changes and population growth. So, this study aims to evaluate the suitability of nixtamalized corn flour (NCF) obtained from new drought-tolerant white corn hybrids planted under drought conditions for gluten-free biscuits production. Chemi...

Metabolic syndrome (MetS) is characterized as a gathering of various metabolic disorders, for example, hyper-glycemia, dyslipidemia, and obesity. The present research was conducted to prepare fortified almond milk as functional beverages and evaluate their protective effect against MetS and associated hepatic and vascular complications. Three bever...

The use of fermentation and nano technology can promote the absorption efficiency and improve the functionality and the added value of cereal by-products. In this study, nano and fermented-nano powders of wheat and rice by-products were prepared by superfine grinding of raw and solid-state fermented materials. Effects of fermentation and superfine...

Background Rapid development of nanotechnology is expected to transform many areas of food technology with increasing investment and market share. Also, phytochemical-rich foods have attracted consumer’s attention due to their ability to promote benefits for human health. So, in this study, the suitability of some food industry by-products [nano-wh...

The effect of roasting conditions on some physicochemical characteristics of coffee beans as color, browning index, hydroxymethylfurfural (HMF), caffeine, phenolic acids, and antioxidant capacity were investigated. The thermostability of chlorogenic acid and caffeine was investigated using Arrhenius equation. Furthermore, principal component analys...

The protective effect of nano-wheat germ (NWG) and nano-rice bran (NRB) was evaluated in Alzheimer's like disease (AD) model associated with dyslipidemia in rats. Both NWG and NRB were analyzed for phenolic compounds, fatty acids, tocopherols, and B-vitamins. Plasma lipid profile and butyrylcholinesterase (BChE), brain oxidative stress and inflamma...
