Abstract Citrus aurantium amara (sour orange) belongs to one of the largest genera Rutaceae family. The species this genus are consumed worldwide as fresh or in form beverages. They include well-known crops lemons, oranges, mandarins, grapefruits, and limes. industrial processing these fruits produces high amounts waste (around 50%) which is a valuable source essential oils. Since they produced...

Studies have shown that oxygenated compounds and TSS/TA are important for beverage and food industries. It seems that Citrus rootstocks have a profound influence on oxygenated compounds and TSS/TA. The aim of this research is to identify rootstock that can synthesize the maximum level of oxygenated compounds and TSS/TA. Peel oil was extracted using mechanical presses and eluted using n-hexane. ...

Tea (Camellia sinensis L.) fruit peel, the main byproduct during the manufacture of tea seed oil, was used as raw material for the recovery of phenolic antioxidants. The effect of ethanol concentration, extraction time, and extraction temperature on total phenolic content (TPC) and ferric-reducing antioxidant power (FRAP) of the extracts from tea fruit peel was investigated. The maximum predict...

In a previous paper (1), the authors have shown that the fumigation of citrus trees with hydrocyanic acid (HCN) for pest control, at a time of the year when the fruit buds are in a certain stage of development, produced ridges and sectors in the outer portion of the peel (flavedo) of the fruit. In the navel orange, Valencia orange and grapefruit varieties, fumigation of trees in February produc...

Carotenoids in the peel of harvested citrus in creased following treatment with ethylene. Im proved color resulted primarily from an increase in the amount of an orange-red pigment, cryptoxanthin, and a red pigment, jg-citraurin. Tempera ture influenced pigment accumulation. At 65 °F and 75 °F, rapid accumulation of both cryptoxanthin and jg-citraurin resulted in highly colored fruit. At 85 °F,...

Rootstock is widely used for the cultivation of citrus fruits because it brings resistance or tolerance to diseases environmental constrains and modulates fruit quality. Polyploidization a widespread improvement strategy in citrus. The objective was evaluate effect rootstock ploidy level on composition essential oils. Two trials were conducted, one displaying ‘Navelina’ orange grafted three roo...

introduction: the aim of this in vitro study was to evaluate the dissolving efficacy of eucalyptol and orange oil solvents associated with passive ultrasonic activation (pua) in zinc oxide-eugenol (zoe) based and epoxy resin-based root canal sealers. methods and materials: seventy samples of each sealer were prepared and then randomized according to the solvent and the time of the ultrasonic ac...

this study aimed to assess the effect of chloroform, eucalyptol and orange oil solvents on the microhardness of human root dentin.sixty-eight single-rooted single-canal extracted human premolar teeth were used. tooth crowns were separated from the roots at the cementoenamel junction (cej). roots were buccolingually sectioned into mesial and distal halves. specimens were randomly divided into 5 ...
