Antifungal Activity of Lemon Essential Oil, Coriander and Cinnamon Extracts on Foodborne Molds in Direct Contact and the Vapor Phase

Abstract

The inhibitory activity of lemon essential oil, coriander extract and cinnamon extract toward five molds (Aspergillus parasiticus, Cladosporium cladosporioides, Eurotium herbariorum, Penicillium chrysogenum and Aspergillus carbonarius) was evaluated using two methods: the agar dilution method and the vapor phase method. The results indicated that the lemon essential oil showed a complete inhibition of growth of the tested molds at ≥1.25 μL/mL using both types of contact tests (in the agar medium and in the vapor atmosphere). Coriander extract had the best antifungal activity in the vapor phase. It completely inhibited As. parasiticus, C. cladosporioides, E. herbariorum and P. chrysogenum at 4.17 μL/ mL. As. carbonarius was partially inhibited. Generally, the cinnamon extract was the weakest inhibitor of the tested molds in both methods.

Bio-preservation Potential of Leaf Extracts of <i>Ocimum gratissimum L.</i> on Fresh-Cut Fruits of <i>Citrullus lanatus</i> (Thunb)

“…It was observed from the analysed oil that γ-Terpinene had the highest percentage composition of 17.210% while 3,4-Xylenol had the lowest percentage composition of 0.126%. The leaves of O. gratissimum have been documented in literature to have antimicrobial property (Nakamura et al, 1999;Nguefack et al, 2009;Mbata and Soukia, 2007;Dambolena et al, 2010;Dimic et al, 2014). Several reports have established that the essential oil with the high amount of γ-Terpinene exhibit anti-inflammatory, antimicrobial antioxidant, anti-proliferative and biopreservation properties (Giweli et al 2012;Silva et al 2014).…”

Extended Storage of Yoghurt by Using Water Extract of Coriander Seeds

“…In raw milk, total lipase activity is sufficient to induce rapid hydrolysis of a large proportion of the fat [47]. Fat slightly decreased in yoghurts with plant extracts, compared to those without extracts; this is because of the antimicrobial activity of coriander extract, which can inhibit the growth of moulds, yeasts and bacteria [48]. [49] has shown that coriander extracts have antimicrobial activity, causing food spoilage; while [50] demonstrated that antioxidant activity is closely related to total phenolic content, such that a higher total phenolic content of the sample relates to higher antioxidant activity, indicating that phenolic compounds are dominant antioxidants.…”

Caracterización química, variabilidad composicional y modelamiento matemático del efecto de aceites esenciales en Alternaria alternata

“…Por ejemplo, Badawy y Abdelgaleil (2014) y Dimić et al (2014) indicaron que el aceite esencial de limón (Citrus limon) inhibió el desarrollo de Botrytis cinerea, Fusarium oxysporum, Aspergillus parasiticus y Penicillium chrysogenum. Manganyi et al (2015) y Lu et al (2013) también reportaron la efectividad del aceite esencial de corteza de canela (Cinnamomum zeylanicum) en el control del crecimiento micelial y la germinación de esporas de los hongos Colletotrichum destructivum, Phytophthora parasitica var.…”

“…For example, Badawy and Abdelgaleil (2014) and Dimić et al (2014) reported that lime essential oil (Citrus limon) inhibited the development of Botrytis cinerea, Fusarium oxysporum, Aspergillus parasiticus and Penicillium chrysogenum. Manganyi et al (2015) and Lu et al (2013) also reported the effectiveness of (Cinnamomum zeylanicum) cinnamon bark essential oil in controlling mycelial growth and spore germination of Colletotrichum destructivum, Phytophthora parasitica var.…”
