the different factors such as harvest time, product handling, temperature and storage duration can be influenced on the different properties of citrus fruits and has considerable economic consequences. therefore a factorial experiment based on completely randomized design with 3 replications was performed to evaluate the effects of harvest times (start of color change, 50% of color change and f...

The present study was focused to evaluate the phytochemical screening and biochemical estimation of ethanolic aqueous extracts edible nuts Arachis hypogea, Anacardium occidentale, Prunus dulcis Juglans regia. showed presence carbohydrate, protein, phenol tannin, flavonoid, glycoside, steroid, alkaloid in all studied nuts. quantification A. hypogeae, P. J. regia were performed determine total am...

Few literature data are available on the nutraceutical properties of little widespread local apple cultivars. Such lack of information prevents exploitation of these germplasms for genetic improvement of new cultivars and for the re-evaluation of local agricultural products, which may attract a large share of consumers oriented towards natural food evoking ancient flavours. In this work eight t...

The influence of harvesting date on some physicochemical properties of nectarine (Prunus persica var. Red gold) fruit including fruit weight, pigment content, total carbohydrate, total phenol and antioxidant activity were studied. Fruits were harvested in four different stages; a) two weeks after fruit set, b) pit hardening, c) three weeks after pit hardening and 6 weeks after pit hardening. Re...

BACKGROUND The study on phytochemical difference between red and black goji berry is limited. METHODS Antioxidant activities and phenolic profiles in terms of total phenol content, total flavonoid contents, condensed tannin content, monomeric anthocyanin content, and total carotenoid content of red goji berry (Lycium barbarum) and black goji berry (L. ruthenicum) were compared using colorimet...

The present study aimed to investigate the phenol content and antioxidant activity of a non-conventional Curcuma sp. namely, Curcuma caesia in comparison with another species, Curcuma amada. The total phenol contents of the methanolic rhizome extracts of C. amada and C. caesia were 37.64 and 44.33 mg Tannic acid equivalents (TAE)/g dry material, respectively. The reducing power, and superoxide,...

“Green” resole phenolic resins for laminating applications were synthesized, and their properties and thermal stability were determined. The plant-based cardanol and condensed tannin were used as the partial substitutes of up to 40% of the phenol in the synthesis of the phenolic resins. The resins were synthesized with different proportions of phenol (P) to cardanol (C) and with different total...
