Research ArticleOpen accessEvery word in the titlePolygalacturonase and Pectin Methylesterase Activities of CaCl2 Treated Red-Fleshed Dragon Fruit (Hylocereus polyrhizus) Harvested at Different MaturityY. B. Awang, S. H. Chuni, M. T.M. Mohamed et al.Fruits harvested at different maturity possess different biochemical constituents and physiological properties that make the fruits may react somewhat differently to the postharvest treatment. A study to examine the activity of Polygalacturonase (PG) and Pectin Methylesterase (PME) enzymes during storage in dragon fruit (Hylocereus polyrhizus) harvested at 28 days (Index 3) and 34 days (Index 5) after anthesis and postharvest … …American Journal of Agricultural and Biological Sciences, Vol. 8, Issue 2 · 23 Jul 2013 · 8,433 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsScreening of Yeast Strains for Pectinolytic Activity: Effects of Different Carbon and Nitrogen Sources in Submerged FermentationsMustafa Oskay, Hüsniye Tansel YalçinTwenty yeast strains were screened for pectinolytic activity, among the strains, only nine were positive for pectinase production. The best strain was Kluyveromyces marxianus NRRL-Y-1109 which gave high quantities of pectinase activity, by submerged fermentation. Different parameters such as incubation time, pH (3.5-7), temperature (20-45°C), nitrogen and carbon source, were optimized. The optimal incubation time, temperature and pH for pectinase … …OnLine Journal of Biological Sciences, Vol. 15, Issue 3 · 22 Jun 2015 · 7,812 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsEffect of Edible Coatings, Storage Time and Maturity Stage on Overall Quality of Tomato FruitsJorge Esteban de Jesús Dávila-Aviña, José Villa-Rodríguez, Reynaldo Cruz-Valenzuela et al.Problem statement: Tomato (Lycopersicon esculentum Mill.) is one of the most widely consumed fresh vegetables in the world; however, its highly perishable nature limits its postharvest life. Major losses in tomato quality and quantity occur between harvest and consumption. Therefore, the application of new technologies to extend the postharvest life of this commodity is needed. The use of edible coatings … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 1 · 14 Mar 2011 · 11,286 accessesView PDF Cite

Research ArticleOpen accessIn the abstractNovel Postharvest Treatment Reduces Ascorbic Acid Losses in Mango (Mangifera indica L.) Var. KentMaria A. Islas-Osuna, Norma A. Stephens-Camacho, Carmen A. Contreras-Vergara et al.Problem statement: Mango is a tropical fruit that ripens very quickly; for this reason, there has been a continuous effort to develop postharvest technologies to extend its shelf life and quality. Among them, 1-Methylcyclopropene (1-MCP) is widely used because it inhibits the action of ethylene receptors. Approach: Changes in physicochemical parameters, bioactive compounds and cell wall degrading activities were evaluated … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 3 · 30 Sep 2010 · 9,127 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffect of Maturity Stage of Papaya Maradol on Physiological and Biochemical ParametersLaura E. Gayosso-García Sancho, Elhadi M. Yahia, Miguel Angel Martínez-Téllez, Gustavo Adolfo González-AguilarProblem statement: Nowadays, the worldwide increase in diseases has motivated consumers to increase the intake of fruits and vegetables, in response to various research reports indicating that fruits and vegetables can help prevent certain types of illnesses, due to their potentially high antioxidant properties. We evaluated the effect of the stage of ripeness of papaya fruit (Carica papaya L.) on … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 2 · 30 Jun 2010 · 11,266 accessesView PDF Cite
