The Postharvest Quality of Fresh Sweet Cherries and Strawberries with an Active Packaging System

Abstract

This study assessed the effect of the recently-introduced Life+ (ILIP, Valsamoggia, Italy) active packaging system on the postharvest quality of sweet cherries and strawberries. This system uses Equilibrium Modified Atmosphere Packaging (EMAP) to achieve specific intra-package conditions with three synergistic elements: an unvented and anti-mist heat sealable container, an active (naturally-antimicrobial) pad, and a heat-sealed, laser micro-perforated film of a specified gas permeability. Post-packaging quality parameters were monitored for 10 (strawberries) and 15 days (cherries): headspace gas concentration, weight loss, titratable acidity, total soluble solids, pH, disease incidence, and sensory quality. Results showed that use of the Life+ system delayed postharvest senescence by maintaining fruit color, acidity, and vitamin C content, and decreasing fruit weight loss and decay. The use of EMAP in sweet cherry resulted in enhanced sensory qualities compared to traditional perforated containers. The results suggest that the Life+ system leads to better sensory properties and improved shelf-life for strawberries and sweet cherries.

Botrytis cinerea and Table Grapes: A Review of the Main Physical, Chemical, and Bio-Based Control Treatments in Post-Harvest

“…In other cases, one treatment aimed to reduce microbial contamination, while another was applied to stabilize fruit quality and the microbial population during cold storage and/or shelf-life [ 27 , 31 , 156 ]. Moreover, it is important to underline that a consistent range of solutions has been developed and tested on other fruits and vegetable [ 157 , 158 , 159 , 160 , 161 , 162 , 163 ] and, in several cases, could be tested/transferred for application on table grapes. Among the other green solutions, poorly explored in grapes, is the exploitation of lactic acid bacteria as biocontrol agents [ 164 , 165 ]: prokaryotic organisms that received interest also in the light of additional positive side effects, e.g., probiotic activity and antagonistic activity against food-borne pathogens [ 166 , 167 , 168 , 169 , 170 ].…”

Erkenci Bölgede Üretilen Kiraz Çeşitlerinin Depo ve Raf Ömrünün Belirlenmesi

“…Farklı kiraz çeşitlerinin hasat (HS), depolama (DS) ve raf ömrü sonrası (RÖS) meyvelerin SÇKM (%), TA miktarı (g malik asit/100 mL) ve pH değerine etkileri TA aroma ve tat açısından kirazlar için oldukça önemlidir. Depolama süresince asitliğin kiraz örneklerinde önemli derecede azaldığı bildirilmekle birlikte Life + poşetleriyle depolanmış ürünlerde ise TA kaybının daha az olduğu belirlenmiştir (Chiabrando et al, 2019). TA miktarlarına bakıldığında depo sonrası ve raf ömrü sonrası çok az bir düşüş görülmektedir.…”

Biodegradable Antimicrobial Food Packaging: Trends and Perspectives

“…The methods employed in obtaining antimicrobial activity vary from adding sachets with volatile antimicrobial agents inside current packaging to incorporating the active agent directly into biopolymers and from coating or grafting antimicrobial substances on polymeric surface to the use of intrinsic antimicrobial polymers or antimicrobial pads ( Figure 1 ) [ 38 , 39 , 40 , 41 , 42 ].…”
