Essential oils as multi-target compounds for novel food safety strategies

This research work has been developed in the context of the potencial applications of essential oils as multi-target compounds for novel food safety strategies, such as active packaging technologies. Essential oils are aromatic oils derived from plants and usually extracted by hydrodistillation when intended to be used in food. There is an increasing interest in the antimicrobial properties of essential oils due to the possibility of using them to replace ‘synthetic’ preservatives in food or, in general, to reduce viable numbers of pathogens along the food chain.

Composition of the essential oil from flowerheads of Chrysanthemum coronarium L. (Asteraceae) wild growing in Southern Italy

2004

The essential oils from the aerial parts of Chrysanthemum coronarium L. (Asteraceae) growing wild in two different localities of Southern Italy, Lascari (L) and Palinuro (P), were obtained by hydrodistillation in a 0.13–0.16% yield. The oils were analysed by GC and GC–MS; 68 constituents, amounting to 89.0% of the oil (L), and 43 constituents, amounting to 91.6% of the oil (P), were identified. The trans‐spiroketal–enol ether 2‐(2,4‐hexadiynylidene)‐1,6‐dioxaspiro[4,4]non‐3‐ene (trans‐tonghaosu) with chrysanthenyl and lyratyl esters and camphor were the main components of the oils.

Antimicrobial, Antibiofilm, and Antioxidant Properties of Essential Oil of Foeniculum vulgare Mill. Leaves

2022

Foeniculum vulgare (Apiaceae) is an aromatic fennel with important practices in medicinal and traditional fields, used in the treatment of digestive complications, and gastrointestinal and respiratory disorders. Its leaves and stems, tender and fresh, are used in the production of pasta dressing and main courses, while its seeds, with a strong smell of anise, are excellent flavoring for baked goods, meat dishes, fish, and alcoholic beverages. The aim of this work is concerning the extraction of essential oil (EO) from the leaves of F. vulgare subsp. vulgare var. vulgare, investigating antimicrobial, antibiofilm, and antioxidant efficacy. In particular, GC-MS analysis showed how the chemical…

Composition and antimicrobial activity of the essential oil of Achillea falcata L. (Asteraceae).

2005

The composition of the essential oil from aerial parts of Achillea falcata L. (Asteraceae) growing wild in Lebanon was analysed by GC and GC–MS; 58 compounds, representing 94.4% of the oil, were identified. Isomers of the cyclobutane ethanol, 1-methyl-2-(1-methylethenyl), grandisol (21.4%) and fragranol (16.8%) were the main components of the oil. Also abundant were artemisia ketone (5.2%), terpinen-4-ol (4.5%) and 1,8-cineole (4.0%). The essential oil shows inhibitory activity mainly against Gram-positive bacteria.

Commercial essential oils: sustainable alternatives in the agri-food industry

2019

Essential oils have enjoyed great popularity from ancient times to today due to agreeable scent and widely known beneficial properties. As a result, nowadays they have become valuable natural ingredients in perfume and cosmetics, food and beverages, agricultural, pharmaceutical and other industries for employment in human health, agriculture and environment, representing potentially safer and more sustainable alternatives to synthetic substances. This Doctoral Thesis has been developed with the aim of corroborating that essential oils are safer and more sustainable alternatives to synthetic products used in the agri-food industry, and consequently promoting their use as “bio” products to ma…

Ocena aktywności przeciwdrobnoustrojowej olejku geraniowego

2017

Olejki eteryczne od lat poddaje się badaniom poszukując w nich alternatywy dla syntetycznych środków konserwujących w kosmetykach. Olejek geraniowy dzięki zawartości głównie geraniolu i cytronelolu stanowi potencjalnie właśnie taką substancję. Celem przeprowadzonych badań było określenie właściwości przeciwdrobnoustrojowych olejku geraniowego. W pracy wykorzystano komercyjny olejek (AvicennaOil). Oceniono aktywność przeciwdrobnoustrojową etanolowego roztworu olejku w zakresie stężeń od 0,25 do 10,0 µl/ml. Materiał biologiczny stanowiły szczepy referencyjne z kolekcji ATCC: Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa oraz Candida albicans. Do badań wrażliwości szczepów na…

Volatile components of Centaurea calcitrapa L. and Centaurea sphaerocephala L. ssp. sphaerocephala, two Asteraceae growing wild in Sicily

2006

The volatile components of the flowerheads of Centaurea calcitrapa L. (C.c.) and Centaurea sphaerocephala L. ssp. sphaerocephala (C.s.) were obtained by hydrodistillation and identified by GC and GC–MS. Altogether 96 components were identified, 66 in C. calcitrapa and 68 in C. spaerocephala, mostly fatty acids (32.8%, C.c. and 44.2%, C.s.) and hydrocarbons (32.3%, C.c. and 15.9%, C.s.). 9,12-Octadecadienoic acid (15.8%, C.c.) and hexadecanoic acid (30.7%, C.s.) were the most abundant fatty acids; tricosane (8.0%, C.c.) and heptacosane (4.9%, C.s.) were the main hydrocarbons. Sesquiterpenes were also present as hydrocarbons (10.1% for 14 components in C.c. and 9.2% for 13 components in C.s.)…
