Special Issue Information

Dear Colleagues,

Fruits and vegetable (F&V) producers, logistic operators, retailers and consumers are the main actors involved in the management of different drivers (technological, economical and social) that affect issues or problems related to the food losses, waste and quality of the product. Quality, however, has become a very complex concept over the last twenty years, as the socioeconomic and cultural changes in society have created a multidimensional construct of the term, which may assume several meanings depending on the target audience, e.g., consumers, food operators and stakeholders, as they have different perspectives throughout the food chain.

Overproduction and excessive stock, inadequate demand forecasting, climate change and weather, product seasonality, short product shelf life, poor operational performance and inadequate handling non-conformance to retail specifications, lack of infrastructures and technical/managerial skill variability, products not harvested due to unprofitable prices, inadequate handling by retailers and consumers, inefficient in-store management, and supply chain inefficiencies (lack of coordination and information sharing) are only some of the most important causes involved in the F&V losses along all the supply chain.

A complementary approach is necessary to limit the F&V losses from field production, and, in turn, retail and consumption. Novel strategies, innovative technology, handling protocols, and concerted actions play key roles in food loss concepts and estimation in the context of Sustainable Development Goal 12, promoted by the United Nations.

The aim of this Special Issue is to highlight and describe,  from an interdisciplinary perspective, recent research regarding solutions to limit pre-harvest and post-harvest losses, which affect fruit and vegetable products (fresh and processed). Short communications, original research and review articles are all welcome.

The potential topics are focused, but are not limited to, the following fields:

  • New agricultural and food technology and engineering;
  • Sustainable technologies for fruit and vegetable processing;
  • Distribution chains in fruit and vegetable processing;
  • Innovative products for enhancing the quality of fruits and vegetables;
  • Evaluation of waste fruit products and evaluation of possible new chain;
  • The development of new quality indexes and appropriate quality assessment methodologies.

Heat treatment is a widely applied technique in the preservation of fruits and vegetables, effectively addressing issues such as disease management, rot prevention, and browning. In this study, we investigated the impact of heat treatment at 35 °C for 24 h on the quality characteristics and disease resistance of two sweet potato varieties, P32/P (Ipomoea batatas (L.) Lam. cv ‘Pushu13’) and Xinxiang (Ipomoea batatas (L.) Lam. cv ‘Xinxiang’). The growth in vitro and reproduction of Rhizopus stolonifer were significantly inhibited at 35 °C. However, it resumed when returned to suitable growth conditions. The heat treatment (at 35 °C for 24 h) was found to mitigate nutrient loss during storage while enhancing the structural characteristics and free radical scavenging capacity of sweet potato. Additionally, it led to increased enzyme activities for APX, PPO, and POD, alongside decreased activities for Cx and PG, thereby enhancing the disease resistance of sweet potato against soft rot. As a result, the heat treatment provided a theoretical basis for the prevention of sweet potato soft rot and had guiding significance for improving the resistance against sweet potato soft rot.

Prediction models of damage severity are crucial for the damage expression of fruit. In light of issues such as the mismatch of existing models in actual damage scenarios and the failure of static models to meet research needs, this article proposes a dynamic prediction model for damage severity throughout the entire process of apple damage and studies the relationship between the initial bruise form and impact energy distribution of apple damage. From the experiments, it was found that after impact a “cell death zone” appeared in the internal pulp of the damaged part of Red Delicious apples. The reason for the appearance of the cell death zone was that the impact force propagated in the direction of the fruit kernel in the form of stress waves; the continuous action of which continuously compressed the pulp’s cell tissue. When the energy absorbed via elastic deformation reached the limit value, intercellular disadhesion of parenchyma cells at the location of the stress wave peak occurred to form cell rupture. The increase in intercellular space for the parenchyma cells near the rupture site caused a large amount of necrocytosis and, ultimately, formed the cell death zone. The depth of the cell death zone was closely related to the impact energy. The correlation coefficient r between the depth of the cell death zone and the distribution of impact energy was slightly lower at the impact height of 50 mm. As the impact height increased, the correlation coefficient r increased, approaching of value of 1. When the impact height was lower (50 mm), the correlation coefficient r had a large distribution range (from 0.421 to 0.983). As the impact height increased, the distribution range significantly decreased. The width of the cell death zone had a poor correlation with the pressure distribution on the impact surface of the apples that was not related to the impact height. In this article, the corresponding relationship between the form and impact energy distribution of the internal damaged tissues in the initial damage of Red Delicious apples was analyzed. This analysis aimed to provide a research concept and theoretical basis for more reliable research on the morphological changes in the damaged tissues of apples in the future, further improving the prediction accuracy of damage severity.

Effects of ball milling (BM) on the structure and physicochemical properties of three types of citrus fibers were investigated. With the extension of the grinding time, the particle size of citrus fibers significantly decreased. Fourier transform infrared spectroscopy (FTIR) showed that the three citrus fibers had similar chemical groups, and more -OH and phenolic acid groups were exposed after BM, and pectin and lignin were not degraded. Scanning electron microscope (SEM) results showed that the appearance of particles changed from spherical to fragmented, irregular shapes. The water holding capacity (WHC), oil holding capacity (OHC), and water swelling capacity (WSC) of citrus fibers LM, JK, and FS reached the maximum value after BM of 2 h (increasing by 18.5%), 4 h (increasing by 46.1%), and 10 h (increasing by 38.3%), respectively. After 10 h BM, citrus fibers FS and JK had the highest adsorption capacity of cholesterol and sodium cholate, increasing by 48.3% and 48.6%, respectively. This indicates that BM transforms the spatial structure of citrus fibers and improves their physicochemical properties. Full article
