Development of nanotechnology requires a constant innovation and improvement in many materials. The exploration of natural resources is a promising eco-friendly alternative for physical and chemical methods. In the present work, colloidal gold nanostructures were prepared using orange peel extract as a stabilizing and reducing agent. The initial pH value of the solution and the concentration of...
The aim of this study was to determine the main constituents of the essential oil isolated from Fortunella crassifolia Swingle peel by hydro-distillation, and to test the efficacy of the essential oil on antimicrobial activity. Twenty-five components, representing 92.36% of the total oil, were identified by GC-MS analysis. The essential oil showed potent antimicrobial activity against both Gram...
Essential oil was extracted from peels of sweet orange fruits by supercritical technique and the resulting compounds were analyzed by gas chromatography. After emulsifying with tween-20 in sterile water, the antibacterial efficacy against Vibrio parahaemolyticus, Salmonella typhimurium, Escherichia coli, and Staphylococcus aureus, which were inoculated on the surfaces of samples of stainless st...
Background and purpose: Intestinal bacterial infections are treated with antibiotics; but there are some reports on the effects of medicinal plants in digestive disorders. Today, medicinal herbs are more suggested due to increasing resistance of bacteria to antibiotics, people are more relying on the medicinal herbs. This study aimed to evaluate the antibacterial effect of orange peel extract. ...
Background: Black spots are a major problem in commercial shrimp species and can have negative effects on shrimps' appearance, quality, shelf life, economic value, and product acceptance by consumers. This study was conducted to investigate the effect of orange peel extract on chemical and sensory qualities as well as black spots on Litopenaeus vannamei species of white farmed shrimp. Methods: ...
The major problem in the fruit juice industry is associated with juice quality deterioration due to the cloud loss of juice concentrates by the enzymatic reaction of pectinmethylesterase enzyme (PME, EC 3.1.1.11). During pectin hydrolysis, pectin and water are transformed into polygalacturonic acid (pectate) and methanol by the action of PME. In this work, a low-intensity ultrasonic technique i...
the use of orange peel as low-cost and eco-friendly adsorbents has been investigated as an ideal alternative to the current expensive methods of removing dyes from wastewater. this paper concerns with the removal of blue 56 from aqueous solutions by orange peel. the effects of ph , initial concentration, adsorbent dosage, and particle size of adsorbent, temperature and also isotherm data analys...
Adsorption of violet B azo dye from aqueous solutions was studied by different cellulose agricultural waste materials (almond shell (AS), pistachio shell (PS), walnut shell (WS), Tea waste (TW) and orange peel (OP)). Cellulose agriculturalwaste sorbents characterized by FTIR and SEM methods. The effects of different parameters such as contact time, pH, adsorbent dosage and initial dye concentra...
Green synthesis of nanoparticles supports reuse, reduce and recycle concept towards the environmental friendly synthesis and also produce the good results compare to chemical methods in some of the cases. MgO nanoparticles can be prepared by solution combustion synthesis using citric acid is a fuel. The same citric acid is available in the nature in so many form just like tamarind, lemon and or...
The present experiment aimed at increasing orange peel and sugar beet pulp protein content through solid-state fermentation by Trichoderma reesei and Trichoderma viride. In vitro digestibility and changes in the chemical composition of the fermented products were determined after seven days of fungal cultivation using gas production tests. The cultivation of T. reesei and T. viride on orange pe...
