Limonene is present in orange peel wastes and is known as an antimicrobial agent, which impedes biogas production when digesting the peels. In this work, pretreatment of the peels to remove limonene under mild condition was proposed by leaching of limonene using hexane as solvent. The pretreatments were carried out with homogenized or chopped orange peel at 20-40°C with orange peel waste and he...

The volatile compounds from Maclura pomifera (Osage orange fruit) peel have been studied by GC-FID and GC–MS. Volatiles fraction proportion was estimated to 60 mg/kg. Identified compounds consist on aliphatics (52.6%), monoterpenes along with sesquiterpenes (27.3%), phenylpropane derivatives along with related compounds (10.0%) and other compounds (10.6%). Among the 60 identified compounds, 1-h...

Introduction The purpose of this study is to examine the effects varying proportions dried-orange-albedo and dried-apple-peel powders in edible coating films for falafel balls on their subsequent oil uptake sensory properties when used during deep frying oil. Methods Coating solutions 3%, 5%, 7% w / v either orange albedo or apple-peel powder were prepared heated 90°C 5 min, after which they co...

The present work was carried out with an aim to isolate an Exo-pectinase producing fungal strain, to optimize physical factors of the enzyme activity and to formulate a media for the cost effective production of the enzyme. Screening, isolation and identification of Aspergillus tamarii and Aspergillus carbonarius were done. Various process variables like pH, temperature and incubation time of t...

We evaluated ameliorative effects of Jamun seed and orange peel extracts on liver toxicity in cypermethrin exposed rat. Methods: Rats were given following treatments daily for 30 d: Group A: Control Group B: Rats received cypermethrin Group C: These rats received cypermethrin and Jamun seed extract simultaneously Group D: These rats received cypermethrin and orange peel extract simultaneou...

The oranges were purchased from the local market of Bela. The orange peel and pulp were subjected to successive extraction with solvents in increasing order of their polarity viz. Acetone, hexane, methanol and distilled water. Orange peel and pulp powder was extracted separately by aqueous extraction. Phytochemical analysis indicated the presence of tannins, saponins etc. Anthraquiones were com...

Production of intracellular β-xylosidase was studied in cultures of Penicillium janthinellum grown on citrus fruit waste supplemented cultivation media. Both dried orange peel and sweet lime peel could induce the production of this enzyme. The working strain showed a pronounced optimum pH and temperature for β-xylosidase production at 6.0 and 27 °C, respectively. The enzyme production was found...

Orange production is constantly growing. The main orange by-product, the peel, a usable source of essential oils with lot health benefits. Because that, it important to find best recovery and encapsulation techniques in order get bioavailability for human ensure highest quality food applications. Thus, aim this work summarize complete process needed obtain oil, from pre-treatments steps, carrie...

The effect of some natural wastes (orange pomace, orange peel, lemon pomace, lemon peel, apple pomace, pear peel, banana peel, melon peel and hazelnut shell) on the production of xylanase from Trichoderma harzianum 1073 D3 has been studied and maximum activity has been observed on melon peel (26.5 U/mg of protein) followed by apple pomace and hazelnut shell. Also, molasses could be used as an a...

Phenolic compounds of unripe and ripe sweet orange peels were determined using a high-performance liquid chromatography separation method with diode array detector (HPLC-DAD). The in vitro antioxidant properties and the EC50 (concentration required to obtain a 50% antioxidant effect) values were also determined. The predominant phenolic compounds were quercitrin, rutin, and quercetin with value...
