“…In addition, packaging of 'Wonderful' pomegranates with polyliners during cold storage has been reported to reduce weight loss [13,64]. Internal packaging creates a modified atmosphere that minimizes water migration from the fruit to the environment, often leading to desiccation [21,26]. Therefore, in the present study, the combination of coatings and polyliners resulted in the least weight loss recorded after 42 days of storage (GA MS + Liner 1 = 4.82%).…”

“…Polyliners, described as passive modified atmosphere packaging (MAP), are an important part of the system with distinct permeability to gases, water vapor and different perforations [23][24][25]. To extend fruit storage and shelf life, polyliners are designed to minimize weight loss, respiration rate, condensation of water vapor and microbial proliferation [23,24,26]. For instance, studies by Lufu et al [21] recommended the use of micro-perforated Xtend ® and macro-perforated (2 mm) polyliners to reduce weight loss and the development of decay in 'Wonderful' pomegranates during cold storage (5 • C).…”

This study investigated the effect of gum Arabic and starch-based coating and two polyliners (Liner 1-micro-perforated Xtend® and Liner 2-macro-perforated high-density polyethylene) on whole ‘Wonderful’ pomegranate fruit during cold storage (5 ± 1 °C and 95 ± 2% RH). Uncoated (UC) and coated (GAMS) fruit were packaged into standard open top ventilated cartons (dimensions: 0.40 m long, 0.30 m wide and 0.12 m high) with (GAMS + Liner 1, GAMS + Liner 2, UC + Liner 1 and UC + Liner 2) or without (UC and GAMS) polyliners. After 42 d, treatment GAMS + Liner 1 recorded the least weight loss (4.82%), whilst GAMS recorded lower (8.77%) weight loss than UC + Liner 2 (10.07%). The highest (24.74 mLCO2 kg−1h−1) and lowest (13.14 mLCO2 kg−1h−1) respiration rates were detected in UC and GAMS + Liner 1, respectively. The highest and lowest total soluble solids were recorded for GAMS (16.87 °Brix), and GAMS + Liner 1 (15.60 °Brix) and UC + Liner 1 (15.60 °Brix), respectively. Overall, no decay was detected for coated fruit packaged with either Liner 1 or Liner 2. Therefore, the combination of GAMS with Xtend® polyliners proved to be an effective treatment to maintain the quality of ‘Wonderful’ pomegranates during storage.

“…8,16 Plastic liners also block the airow path (increases airow resistance) and hence increase the time and energy usage of cooling operations. 27 In addition, plastic food packaging poses innumerable environmental and public health risks so biodegradable and sustainable alternatives such as surface waxing/coating have been investigated. 9,28,29 Before choosing an appropriate technology for strategic optimal moisture loss control, there is a need to understand the moisture loss characteristics of a commodity.…”

“…Micro‐perforated films (perforation diameter not more than 200 μm) with adequate dimension and the correct number of perforations can provide excellent gas exchange rates to develop the desired modified atmosphere and prevent water condensation 5,6 .

“…5,6 Micro-perforated films have been reported to increase shelf life and maintain the quality of many fruit and vegetables. 3,[7][8][9][10] Several factors can impact gas transmission through perforated media, such as perforation diameter and number, film thickness, airflow and temperature. 11 Allan-Wojtas et al 12 reported that the transmission rate for O 2 and CO 2 increased linearly with the individual perforation area in micro-perforated films.…”

Role of laser micro‐perforations on ethylene transmission rate in packaging materials used for fresh produce

et al. 2022

View full text Add to dashboard Cite

Ethylene transmission through the packaging plays a vital role in determining the ethylene concentration inside the fresh produce package. Several investigations describing the oxygen, water vapour afnd carbon dioxide transmission in modified atmosphere packaging have been studied previously; however, there is a lack of studies on the ethylene transmission rate. Hence, this study aimed to investigate the ethylene transmission through a laser perforated oriented polypropylene packaging film, commonly used in fresh produce packaging. The impact of the perforation diameter (50-150 μm) and film thickness (20, 25 and 30 μm) at a temperature of 25 C on ethylene transmission rate was investigated. The ethylene transmission rate (k C 2 H 4 ) varied from 6.75 to 10.06 cm 3 h À1 . It was found to be varied significantly (p ≤ 0.05), proving its dependency on the selected perforation diameter and film thickness. An increase in the perforation diameter of packaging film increased the k C 2 H 4 exponentially, whereas the film thickness had less influence on the k C 2 H 4 . A model based on the perforation diameter and film thickness was employed with an acceptable R 2 of 0.98. The model parameters (a = 17.44; b = 0.35; c = 0.14) determined in this study would be helpful in designing a packaging system for fresh produce that minimise ethylene accumulation.
