“…Change in aril colour was not clear; however, application of MC + TO 0.5% and MC + TO 0.25% coatings inhibits the loss of redness compared to uncoated fruit arils. Likewise, Öz and Eker [42] reported reduced loss of redness in arils extracted from "Tarom" pomegranates treated with starch coatings enriched with of N. sativa before cold storage (4 • C and 95% RH) for 12 days. The observed changes in chroma values corroborate with Azarakhsh et al [43] who observed a decrease over time in chroma values of fresh-cut pineapple coated with gellan gum-based coating during cold storage.…”

The effects of gum arabic (GA; 1.5% w/v) and methyl cellulose (MC; 1% w/v) enriched with thyme oil (TO; 0.25 and 0.5% v/v) on the quality of “Acco” pomegranate arils were studied. Coating treatments, namely, MC, MC + TO0.5%, MC + TO0.25%, GA, GA + TO0.5% and GA + TO0.25% were applied on arils by dipping, and evaluations were made on physicochemical and microbiological quality, phytochemicals and antioxidant capacity of arils stored (5 ± 1 °C, 95 ± 2% RH) for 16 days. Dipping arils in GA or MC, both containing TO (0.5% v/v) significantly (p < 0.0001) reduced weight loss and enhanced antioxidant activity (FRAP) (p = 0.0014). However, dipping arils in GA combined with TO (0.25% v/v) had the highest influence on reducing aril respiration rate compared with other treatments. Overall, results showed that application of coatings (GA + TO0.5% and GA + TO0.25%) reduced total yeast and mould and total plate counts and maintained quality up to 8 days of storage. These findings suggest that either GA + TO0.5% or GA + TO0.25% coatings have the capability to extend storage life of “Acco” pomegranate arils.

“…Considering this, developing postharvest treatments for preserving "Wonderful" pomegranate is a high priority. Several authors have reported edible coatings as a promising treatment for pomegranate whole fruit and fractions to minimize postharvest losses during storage and shelf life [23,36,[49][50][51]. However, limited studies derive edible coating formulations with optimum concentrations of ingredients to potentially extend pomegranate storage and shelf-life.…”

The effects of edible coatings based on gum arabic (GA) (0.5–1.5%), maize starch (MS) (0.5–1.5%), lemongrass oil (LO) (2–4%), and glycerol (GC) (0.5–1%) developed using response surface methodology (RSM) on “Wonderful” pomegranate fruit were studied. After 42 days of storage (5 ± 1 °C, 95 ± 2% RH) and 5 days at ambient temperature (20 ± 0.2 °C and 60 ± 10% RH), whole fruit were evaluated for weight loss (%) and pomegranate juice (PJ) for total soluble solids (°Brix), titratable acidity (% Citric acid), and antioxidant capacity. The optimization procedure was done using RSM and the response variables were mainly influenced by the concentrations of MS and GA. The optimized coating consisted of GA (0.5%), MS (0.5%), LO (3%), and GC (1.5%) with desirability of 0.614 (0—minimum and 1—maximum). The predicted values of response variables, for the coating were weight loss (%) = 5.51, TSS (°Brix) = 16.45, TA (% Citric acid) = 1.50, and antioxidant capacity (RSA = 58.13 mM AAE/mL PJ and FRAP = 40.03 mM TE/mL PJ). Therefore, the optimized coating formulation is a potential postharvest treatment for “Wonderful” pomegranate to inhibit weight loss and maintain overall quality during storage and shelf-life.

Narın sahip olduğu yüksek besleyici değeri ve benzersiz duyusal özellikleri sebebiyle tüketici talebi ve ticari üretimi son yıllarda artmıştır. Buna ek olarak, nar biyoaktif bileşenler açısından zengin bir kaynaktır ve bu yüzden tüketimi sağlık bakımından birçok fayda sağlamaktadır. Klimakterik olmayan doğasına rağmen, pazarlanabilirliği ve tüketici tarafından kabulü; soğuk zararı, çatlama, kabukta kahverengileşme ve çürüme gibi çeşitli faktörlerden sınırlanmaktadır. Bu problemleri önlemek için farklı hasat sonrası uygulamalar kullanılmaktadır. Bu yöntemler; ısı uygulamaları, modifiye atmosfer ambalajlama, yenilebilir kaplamalar, kimyasal ajanlar ve engel teknolojisini içermektedir. Bu nedenle derlemenin amacı; narın sağlığa faydası, ekonomik değeri ve hasat sonrasında kullanılan farklı teknolojilerin bütün nar ve nar taneleri üzerine etkisini güncel kaynaklardan yararlanarak özetlemektir.
