Anti-Listeria activity of citrus essential oils in a fresh ovine cheese
2023
The aim of this study was to evaluate the anti-Listeria activity of essential oils (EOs) extracted from the peel of lemons, oranges and tangerines in a fresh cheese produced with pasteurized ewe’s milk. Four cheesemaking trials were performed at the pilot plant scale level, including one control production without the addition of EOs and three experimental productions obtained by the addition of 200 μL/L of each EOs to milk. Before the addition of EOs, the milk of all trials was inoculated with 107 CFU/mL of the starter cultures (Lactococcus lactis NT1 and NT5) and 104 CFU/mL of pathogenic bacteria (Listeria monocytogenes ATCC19114). Plate counts confirmed the dominance of the starter cultu…
Effects of Citrus essential oils on weed emergence and on soil microorganisms
2017
Weed invasion is a major problem for agricultural productivity since causes economic and environmental damages. Weed control can be achieved through chemical, mechanical, biological and cultural means. Although synthetic herbicides are effective for weed control, they have a negative impact on soil and the environment. Therefore, it is important to develop alternative means that are in the meanwhile effective and ecofriendly. EOs are commonly used for bactericidal, virucidal, fungicidal, antiparasitical, insecticidal, medicinal and cosmetic applications. Citrus EOs are the most widely used in the world for many purposes. Moreover, some studies have recently investigated their potential as h…
Sicilian potential biogas production from Citrus industry by-product
2017
In Europe, Italy is the second nation after Spain in Citrus production and 49% ca. of national fruit production is located in Sicily. The by-product obtained from the industrial processing of Citrus fruits into juice and essential oils is called “pastazzo” or Citrus Waste (CW). This study is aimed at evaluating the Sicilian potential biogas and energy production from the above “pastazzo” and verifying the possibility of using this by-product for Anaerobic Digestion (AD) process within 30 km from processing plants. The areas cultivated with Citrus species in Sicily and their distribution in the various municipal districts were mapped and analysed by means of QGIS software, together with the …
Current and Potential Use of Citrus Essential Oils
2013
Since the Middle Ages, citrus essential oils (EOs) have been widely used for their bactericidal, virucidal, fungicidal, antipara- sitical, insecticidal, medicinal and cosmetic proprieties. Also nowadays, they find important applications in pharmaceutical, sanitary, cosmetic, agricultural and food industries. The best method to extract EOs from citrus plant tissue is steam distillation because of a vari- ety of extracted volatile molecules such as terpenes and terpenoids, phenol-derived aromatic components and aliphatic components. In vitro physicochemical assays classify most of them as antioxidants.
Association of Taste Perception for Sweet, Salt, Sour, Bitter and Umami and Food Intake Among Community-dwelling Adults in the PREDIMED-PLUS Trial (P…
2019
OBJECTIVES: To investigate the association between taste perception for sweet, salt, sour, bitter and umami and food category intakes. We hypothesized that greater taste perception will be inversely associated with the amount consumed. METHODS: A cross-sectional baseline analysis was performed on community-dwelling overweight adults with metabolic syndrome (N = 367, 55–75y) from the PREDIMED-PLUS Trial, University of Valencia Center, Spain. Taste perception was determined by challenging subjects with standard solutions of sweet, salt, sour, bitter and umami (400 mM sucrose, 200 mM NaCl, 34 mM citric acid, 5.6 mM phenylthiocarbamide (PTC), 200 mM monopotassium glutamate, respectively) and ev…
Recurrent deficit irrigation and fruit harvest affect tree water relations and fruitlet growth in ‘valencia’ orange
2019
Background – Partial rootzone drying is an irrigation strategy known for increasing water use efficiency without significantly affecting tree water status. ‘Valencia’ oranges have a very long development period and nearly mature fruit and new fruitlets may be present at the same time on the tree, competing for water and assimilates. Objectives – The present study investigates the effect of recurrent deficit irrigation and fruit harvest on tree water status and fruitlet growth of ‘Valencia’ orange. Methods – Forty-eight adult trees were exposed to three irrigation treatments for seven years (2007–2013): irrigation with 100% of ETc (CI), continuous deficit irrigation (DI, 50% of CI) and parti…
