Effects of fludioxonil, propolis and black seed oil application on the postharvest quality of “Wonderful” pomegranate

Abstract

Pomegranate fruit consumption has increased rapidly throughout the world, mainly because of its medical and nutritive attributes. Thus, considerable commercial and scientific interest exists in prolonging its postharvest life with non-chemical applications as much as possible to meet the year-round demand for this fruit. The present work aimed to study the effects of black seed oil (0.1% and 0.5%), propolis (0.01% and 0.1%) and fludioxonil (0.06%), with and without modified atmosphere packaging (MAP), on the postharvest quality of pomegranate cv. Wonderful. Treated fruits were stored at 6.5±1 °C and 90–95% relative humidity for 150 days. The results indicated that both black seed oil and propolis treatments significantly influenced the maintenance of fruit weight and quality. At 150 days after storage, the fruit weight loss of the samples treated with MAP + 0.5% black seed oil, MAP + 0.1% propolis and MAP alone were found to be 5.5%, 6.3%, and 9.1%, respectively, whereas the weight loss of the untreated control fruits was 19.8%. Application of either 0.5% black seed oil or 0.1% propolis, especially when combined with MAP, was also effective in controlling gray mold development and slowing the occurrence of chilling injury.

Improving Postharvest Storage Quality of Cucumber Fruit by Modified Atmosphere Packaging and Biomaterials

“…The ability of MAP to prevent weight loss was previously reported by several researchers for various fruits (Caleb et al, 2013;Dhall et al, 2012;Kahramano glu et al, 2018) and for cucumber fruits (Manjunatha and Anurag, 2014;Wang and Qi, 1997). In addition, application of PEx and LO was found to reduce weight loss of cucumber fruit, in agreement with previous studies carried out on different fruits (Kahramano glu 2019;Kahramano glu et al, 2018;€ Ozdemir et al, 2010;Prakash et al, 2015;Zahid et al, 2013). Results also suggest that the combination of MAP with LO or PEx better prevents weight loss.…”

“…Results also suggest that the combination of MAP with LO or PEx better prevents weight loss. Kahramano glu et al (2018) and Kahramano glu (2019) presented similar results for different crops with PEx, LO, and black seed oil treatments.…”

“…The material was first dissolved in 70% ethanol (10/90 v/v). Pure water was then added to the solution as suggested by Kahramano glu et al (2018) to prepare 0.2% and 0.5% doses of LO. Crude propolis was collected from Ba glık€ oy province, northern Cyprus.…”

“…Current postharvest studies are mainly focusing on the use of biomaterials, including essential oils (EOs), edible coatings, and plant extracts to preserve storage quality in fresh produce (Silvestre et al, 2011). Previous studies have described a number of successful biomaterials in postharvest storage studies, including chitosan (Adiletta et al, 2018;Guti errez-Martínez et al, 2018;Sharif et al, 2015), EOs (Kahramano glu 2019; Pavela and Benelli 2016;Prakash et al, 2015), PEx (Kahramano glu et al, 2018;€ Ozdemir et al, 2010), plant extracts (Gatto et al, 2016;Obagwu and Korsten 2003), edible coatings (Dang et al, 2008;Panahirad et al, 2019;Saucedo-Pompa et al, 2009), and organic salts (Troyo and Acedo, 2019). In addition, MAP is an important nanotechnology for maintaining postharvest quality and upgrade the storage duration of fresh produce (Caleb et al, 2013).…”

Insight on Propolis from Mediterranean Countries: Chemical Composition, Biological Activities and Application Fields

“…In Cyprus some authors have tested the use of propolis from Cyprus on the post-harvest quality of pomegranate with/without modified atmosphere packaging (MAP) and have found that propolis, not only, significantly influence the maintenance of fruit, weight, juice content and visual quality and marketability, but also controlled gray mold development and slowed the occurrence of chilling injury.
