“…Considering the importance of such losses and the need for better packaging design tools, many other investigations for agricultural products based on mechanical damages were performed in the last years, some of them focused on the product performance (BERARDINELLI et al, 2005;FERREIRA et al, 2006;GOMES, 2006;ZHOU et al, 2007;FERRAZ & LACERDA, 2007;SANCHES et al, 2008;VALENTINI et al, 2009) and others focused on packaging design (CHONHENCHOB et al, 2008;JARIMOPAS et al, 2008;THOMPSON et al, 2008;ZHOU et al, 2008). They somewhat used conventional approaches either to investigate the response of the vegetable tissue solely or the produce-package system by evaluating changes in physical-chemical properties after a mechanical stress.…”

ABSTRACT:The vibration during transportation is one of the main causes of fruit damage. The actual methodologies used for damage evaluation in fruits seem to be subjective, since most of them are based on visual evaluation. In this study the effect of vibration, for one and two hours, on polyphenoloxidase (PPO) activity in peach pulp was investigated. The relation among PPO activity variation, postharvest time and resting time were also considered. Results showed that vibration affects PPO activity. However, it was not possible to correlate PPO activity variation and vibration.KEYWORDS: polyphenoloxidase, vibration, damage, peach. ATIVIDADE DE POLIFENOLOXIDASE EM PÊSSEGOS APÓS VIBRAÇÃO RESUMO:A vibração durante o transporte é uma das principais causas de dano em frutas. As metodologias atuais utilizadas na avaliação de danos em frutas parecem ser subjetivas, visto que a maioria delas é baseada em avaliações visuais. Neste trabalho, investigou-se o efeito da vibração em dois níveis, uma e duas horas, sobre a atividade de polifenoloxidase (PPO) em pêssegos. A relação entre a variação da atividade de PPO, tempo pós-colheita e tempo de repouso também foi considerada. Os resultados mostraram que a vibração afeta a atividade de PPO. Entretanto, não foi possível correlacionar a variação da atividade de PPO e a vibração. PALAVRAS-CHAVE:polifenoloxidase, vibração, dano, pêssego.

“…Identifying practices that contribute to mechanical bruising and preventing defect fruit from reaching the retail shelf is key to reducing fruit losses and ensuring consumer confidence. A new suspended fruit packaging system was recently developed to ensure damage-free transport of soft fruit [22]. The authors demonstrated that soft fruit could be effectively cushioned from transit vibration damage using the suspended tray packaging system [22].…”

Extension of Avocado Fruit Postharvest Quality Using Non-Chemical Treatments

Developing postharvest management techniques using environmentally friendly and non-chemical approaches is key to extending the shelf life of avocados in a safer and health conscious manner. Avocados are prone to postharvest deterioration caused by mechanical damage, chilling injury, soft landing, uneven ripening and decay. Among the different cultivars of avocados commercially grown worldwide, the ‘Hass’ variety continues to be the most predominant due to its nutty flavour and functional properties. Most of the literature on postharvest decay and disorders affecting avocado fruit quality during storage and marketing is dedicated to the Hass avocado. Some of these postharvest problems are unique to the ‘Hass’ avocado can possibly be controlled by simply investing more research into other cultivars. These postharvest losses can be significantly controlled using eco-friendly technologies, such as modified atmosphere, physical heat treatments and most importantly investing in natural biodegradable products with naturally inherent antimicrobial properties. Thus, this review includes the recent research-based information on the use of non-chemical treatments on the improvement of fruit health and quality.

“…The mechanical damage to blueberries mainly includes two parts: compression and impact damage. Compression and impact contact of fruit are both important parts of biomaterial mechanics, involving the deformation behavior of biological objects under force (Fernando, Fei, Stanley, & Enshaei, 2018; Li, Li, & Liu, 2011; Li, Miao, & Andrews, 2017; Thompson, Slaughter, & Arpaia, 2008). The difference between compression and impact is the length of the action time.…”

Blueberries are prone to mechanical damage during the processes of grading, packaging, transportation, and selling, and stack damage is one of the important causes of blueberry quality loss. The mechanical parameters of blueberry should be obtained firstly to create the mechanical model for analyzing the stack problems of multilayer blueberries. Precise mechanical parameters were obtained for the first time by performing a compression experiment and analyzing an explicit dynamics simulation based on the finite element model. It was found that the elastic modulus of the blueberries was 0.225 MPa and that the Poisson's ratio of the blueberries was 0.35. The placement direction of the blueberries had the greatest impact on the rupture force, followed by the number of stacked layers and the loading speed. A regression model
