Received: 18 September 2019; Accepted: 18 October 2019; Published: 24 October 2019 Featured Application: Reliable and rapid analysis of free fatty acid (FFA) in olive oil is possible from the relative intensity ratio of characteristic vibrational modes observed by Raman spectroscopy. Abstract: Free fatty acid (FFA) is one of the most critical parameters for evaluating the quality of olive oil. In this paper, we present a simple and rapid Raman spectroscopy method for analyzing free fatty acid in olive oil. First, FFA degradation of carotenoids in olive oil is confirmed by analyzing the relative intensity of characteristic vibrational modes and introducing an intensity decrease factor. Second, it is demonstrated that the relative intensity ratio of the two characteristic vibrational modes 1 1 at 1525 cm− and 1655 cm− presents a good and rapid analysis of FFA content in olive oil; the relative intensity ratio decreases linearly with FFA content. In addition, resonance Raman scattering of carotenoid is discussed, showing that a green laser should be utilized to study FFA in olive oil.

In that aspect, the olive varieties “Koroneiki” and “Mastoidis” were employed in a mild cold stress experiment, imitating night frost incidents to assess their biochemical, physiological and reproductive functions in relation to genotype. The physiological performance of the stressed plants was not significantly altered, suggesting that both cultivars were well adapted to mild cold night stress. The biochemical response of the plants, regarding antioxidant enzymes, H2O2 and TBARS accumulation, confirmed that both cultivars could cope with the stress applied. The mRNA levels of the PPO gene, which participates in hydroxytyrosol biosynthesis and plant defense, were elevated after 24-h stress at 0 ◦C, in both cultivars with “Mastoidis” plants exhibiting higher levels for a longer period. -

López-Escudero, Ana Gordon Bermúdez-Coronel and Concepción Muñoz Díez * Department of Agronomy (Excellence Unit ‘María de Maeztu’ 2020-23), ETSIAM, University of Córdoba, 14071 Córdoba, Spain; [email protected] (P.V.C.); [email protected] (C.T.R.); [email protected] (D.B.N.); [email protected] (F.J.L.-E.); [email protected] (A.G.B.-C.) * Correspondence: [email protected] Abstract: The use of genetic resistance is likely the most efficient, economically convenient and en- vironmentally friendly control method for plant diseases, as well as a fundamental piece in an inte- grated management strategy. This is particularly important for woody crops affected by diseases in which mainly horizontal resistance mechanisms are operative, such as Verticillium wilt, caused by Verticillium dahliae. In this study, we analyzed the variability in resistance to Verticillium wilt of olive trees in progenies from five crosses: ‘Picual’ × ‘Frantoio’, ‘Arbosana’ × ‘Koroneiki’, ‘Sikitita’ × Citation: Valverde, P.; Trapero, C.; ‘Arbosana’, ‘Arbosana’ × ‘Frantoio’ and ‘Arbosana’ × ‘Arbequina’ and their respective reciprocal Barranco, D.; López-Escudero, F.J.; crosses. Additionally, seedlings of ‘Picual’ and ‘Frantoio’ in open pollination were used as controls. Gordon, A.; Díez C. M. Assessment In October 2016 and 2018, the fruits were harvested, and seeds germinated. Six-week-old seedlings of maternal effect and genetic varia- were inoculated by dipping their bare roots in a conidial suspension of V. dahliae, and disease pro- bility in resistance to Verticillium gress in terms of symptom severity and mortality was evaluated weekly. -
Identification and Quantification of Olive Oil Quality Parameters Using
agriculture Article Identification and Quantification of Olive Oil Quality Parameters Using an Electronic Nose Nawaf Abu-Khalaf Department of Agricultural Biotechnology, Faculty of Agricultural Sciences and Technology, Palestine Technical University-Kadoorie (PTUK), Tulkarm P.O. Box 7, Palestine; [email protected] Abstract: An electronic nose (EN), which is a kind of chemical sensors, was employed to check olive oil quality parameters. Fifty samples of olive oil, covering the four quality categories extra virgin, virgin, ordinary virgin and lampante, were gathered from different Palestinian cities. The samples were analysed chemically using routine tests and signals for each chemical were obtained using EN. Each signal acquisition represents the concentration of certain chemical constituents. Partial least squares (PLS) models were used to analyse both chemical and EN data. The results demonstrate that the EN was capable of modelling the acidity parameter with a good performance. The correlation coefficients of the PLS-1 model for acidity were 0.87 and 0.88 for calibration and validation sets, respectively. Furthermore, the values of the standard error of performance to standard deviation (RPD) for acidity were 2.61 and 2.68 for the calibration and the validation sets, respectively. It was found that two principal components (PCs) in the PLS-1 scores plot model explained 86% and 5% of EN and acidity variance, respectively. PLS-1 scores plot showed a high performance in classifying olive oil samples according to quality categories. The results demonstrated that EN can predict/model acidity with good precision. Additionally, EN was able to discriminate between Citation: Abu-Khalaf, N. -

Captive Fatty Acids of Fresh Olive Oils?
GRASAS Y ACEITES 72 (2) April-June 2021, e413 ISSN-L: 0017-3495 http://grasasyaceites.revistas.csic.es INFORMATIVE NOTE Captive fatty acids of fresh olive oils? J.A. Cayuela-Sánchez Department of Biochemistry and Molecular Biology of Plant Products. Instituto de la Grasa, CSIC, Universidad Pablo de Olavide, 46, Crtra. Utrera, Km. 1, 41013 Corresponding author: [email protected] Submitted: 04 May 2020; Accepted: 06 October 2020; Published online: 10 June 2021 SUMMARY: Olive oil is mainly made up of triglycerides. It is well known that olive oil contains free fatty acids, the proportion of which is variable, depending on the extent of the hydrolysis of triglycerides. Besides, globular structures have been reported in cloudy virgin olive oils. The pseudo-walls of these globules would be constituted by amphiphilic molecules, while fatty acids are amphiphilic. This brief review aims to inform on the importance of the possible interaction of ‘free’ fatty acids of veiled virgin olive oils, as structural units in the pseudo-wall of the colloidal globules, already reported. The binding of fatty acids to the colloidal globules can mean they are not free in the olive oil. They could be ‘captive’ in said pseudo-walls, thus exerting less influence on the perception of acidity by the consumer or taster of the olive oils. The official method of analysis of olive oil acidity cannot detect this effect. This may suppose that functional acidity is lower than the acidity values determined by chemical analysis in cloudy virgin olive oils. KEYWORDS: Captive fatty acids; Colloid; Colloidal globules; Free fatty acids; Veiled virgin olive oil. -

Urban Transcripts IN PARTNERSHIP WITH WITH THE SUPPORT OF The city as a laboratory On the Sea Edge An International Urban Design Workshop 29 August - 4 September 2016 Chania, Crete, Greece Exploring Chania as an urban laboratory on the sea edge the workshop brings into focus a number of issues common to medium-scale coastal cities in Greece, the Mediterranean, and beyond: abandoned places and urban voids, disputed edges where the ground dips into the sea, sites of remembered his- tories and forgotten stories, contested interfaces where the public meets the private, hybrid spaces where the physical merges with the digital, urban disorders regulated into grids and zones, local com- munities transforming within an international tourist market. At times clearly delineated, at others blurry, and always in flux,it is the edge that is this workshop’s primary matter: the edge between abandonment and occupation, memory and oblivion, public and private, physical and digital, land and sea, spontaneity and regulation, community and market. Making use of design and policy tools for shaping and managing space the workshop aims at a series of urban design proposals for specific sites in the city where these phenomena are most strongly manifested. The selected sites in each of the 7 units of the workshop thus function as a lens through which an exploration of broader issues can be embarked upon and brought to a productive design-oriented con- clusion. On the Sea Edge immerses participants into an intensive 7-day programme consisting of design studio teamwork, fieldwork research, and lectures, complemented with parallel public and social events. -

Koniditsiotis Stavros Msc of Cultural Policy and Development, Open University of Cyprus, Cyprus ABSTRACT The history oF the olive tree, its cultivation and its products is known For centuries. Some olive tree have survived over millennia and their history dates back to antiquity. In many cases, it is related to mythology and religion. The olive tree is associated with Folk tradition, people's everyday liFe, and customs. In Greece, monumental olive trees are found in the Peloponnese, Crete, Euboea, Chios, Pelion and Attica. This paper explores and describes the particular morphological Features such as shape, size, wood, cavities and age, as well as the cultural characteristics such as historical or religious events, myths and traditions that deFine an olive tree and characterize it as monumental. The main aim oF our research is to examine the key position that monumental olive trees and their materialistic and symbolic maniFestations consist a natural and cultural heritage as well. In this framework the study focuses on various key issues related to monumental olives trees and their natural, historical, social and cultural value. Keywords: Monumental Olive Trees, Nature conservation monuments, Natural sites, Greek monumental Olive Trees, Cultural heritage of olive Trees. 1. INTRODUCTION The present study is a part of a wider research on the value of the natural heritage and specially on ancient olives trees as natural monuments and cultural heritage of all Mediterranean regions. -
