A series of monoliths are prepared from orange peels and chemically activated with H 3 PO 4 , KOH, ZnCl 2 , and water vapor without a binder. The monoliths were characterized by N 2 adsorption-desorption isotherms at 77 K, Boehm titrations and XPS. Thereafter, monoliths were tested for their ability to establish NO x retention. The results show that the retention capacities of NO x were a funct...

The aim of this study is to produce edible films with antimicrobial properties by using the discarded fruit peels (orange and lemon) as extracts determine effect on shelf life rainbow trout fillets squid rings. For purpose, were performed orange lemon xanthan, locust bean carrageenan gums. Rainbow (Oncorhynchus mykiss 1792) rings (Loligo vulgaris 1798) covered from extend shelf-life these produ...

In this study, microwave-assisted extraction was applied for pectin extraction from the dried orange peel and Box-Behnken response surface design was used to study and optimize the effects of processing variables (microwave power, irradiation time, pH and solid-liquid ratio) on the yield of pectin. The amount of pectin extracted increased with increasing microwave power, while it reduces as the...

Chemical properties of cationic biosorbents, the orange peel and the lemon peel, have been studied. ATR and Raman spectra indicated that the functional groups in the peels structure responsible for dye sorption are carboxyl groups (COOH and COOM, M=Na,K,Ca,Mg) and hydroxyl groups (OH). Increasing the mass of the peels in water suspensions a decrease in dissociation of both, the –COOH and –COOM ...

India is among 23 nations where in a large population suffers from dental and skeletal flourosis due to high fluoride concentration in ground water. The prominent states, which are severely affected, are Andhrapradesh, Rajasthan, Gujarat, Uttar Pradesh and Tamil Nadu. Fluoride beyond desirable amounts (0.6 to 1.5 mg/l) in ground water is a major problem in many parts of the world. Taking the se...

Industrial by-product like orange peel plays an important role in pectin manufacture. The objective of this article was to extract pectin from peel of Citrus sinensis and to study the effect of its incorporation on the quality of yogurt during the period of fermentation and postacidification. Physicochemical, organoleptic, and rheological properties of yogurt prepared with pectin were studied i...

This study was carried out to determine the ability of Rhizobium species CWP G34B to degrade the peels of selected Nigerian fruits. The potential of the bacterium to digest some carbon sources (lactose, maltose, sucrose and mannitol) and peels of some Nigerian fruits (pineapple, orange, plantain, banana, pawpaw and mango fruits) was investigated by growing the organism on the substances separat...

Citrus plants are the rich source of secondary metabolites which includes alkaloids, steroids, tanins, flavonoids, phenols and polyphenols. Having the rich source of polyphenols and natural flavonoids draw attention to screen the phytochemical compounds and their beneficial activities from different solvents. The present investigation explore the in vitro antioxidant activity of orange (Citrus ...

A new colorimetric method for determination of diosmin is proposed. The method is based on formation of a chromophore by the flavonoid in presence of 75% (v/v) HCl showing maximum absorbance at 405 nm. The technique with linearity over 10 through 80μg flavonoid (r ± s.e. = 0.9994 ± 0.0008, b±s.e. = 0.0089 ± 0.0001, COV ± s.e. = 2.8 ± 0.5, n= 6 each) has been compared with standard aluminium chl...
