Special Issue Information

Dear Colleagues,

The purpose of this Special Issue, “Postharvest Quality and Microbiological Control of Fruit and Vegetables”, is to disseminate research focused on preserving fruit and vegetables through innovative methods or novel applications of existing techniques.

Post-harvest techniques play a crucial role in determining the final quality and shelf life of fruit and vegetables. The proliferation of microorganisms is one of the main causes of fruit spoilage. Due to their high perishability, fruit and vegetables are among the food products with the highest levels of loss and waste (FLW). Reducing these losses is essential to contributing to Sustainable Development Goal (SDG) 12, particularly target 12.3 which aims to halve global per capita food waste at the retail and consumer levels by 2030, and to reduce food losses along production and supply chains, including post-harvest losses. It is essential to identify the causes of post-harvest losses and to develop study methods that extend shelf life while preserving the nutritional and sensory quality of fruit and vegetables at the time of consumption. These methods must also align with consumer expectations for healthy, environmentally friendly products free from chemical additives. Addressing this challenge requires a timely and decisive response.

The objective of this study was to evaluate the influence of modified atmosphere and moisture absorbers on specific metabolites (SMs) content in packaged stinging nettle leaves (Urtica dioica L.). Hydroponically cultivated fresh nettle leaves were packaged in two experiments: 1. packaging in ambient or modified atmosphere (MAP) and 2. packaging in MAP without or with moisture absorbers. The results demonstrated that both modified atmosphere and moisture absorbers statistically significantly affected (at p ≤ 0.05) the SM content of nettle leaves, but with opposing effects. Specifically, leaves packed in modified atmosphere had significantly higher values of phenolic compounds, ascorbic acid, total chlorophylls, and antioxidant capacity compared to ambient packaging. In contrast, the inclusion of moisture absorbers in packages was associated with a general decline in metabolite content. The highest levels of caffeoylmalic acid (405.73 mg/100 g fm), total phenolic compounds (627.35 mg GAE/100 g fm), total chlorophylls (0.87 mg/g fm), and antioxidant capacity (ABTS: 24.5 µmol TE/g, DPPH: 6.98 µmol TE/g, FRAP: 43.85 µmol TE/g fm) were observed in samples stored for 17 days under modified atmosphere without the addition of absorbers. Based on these findings, for optimal preservation of SMs during extended storage (up to 20 days), packaging stinging nettle leaves in a modified atmosphere without moisture absorbers is recommended.

Peach consumers demand good quality fruit, but premature harvests result in fruit that does not ripen properly and does not reach the required organoleptic quality, so consumers stop buying this product that does not meet their expectations. In our region, peaches are exported long distances, and it is required that when they reach the destination market their quality is adequate. Therefore, the objective of this study was to determine the storage capacity of commercial and delayed harvest in three peach cultivars. ‘Rich Lady’, ‘Summer Lady’, and ‘Merryl O’Henry’ were harvested at commercial maturity (H1) and, a few days later (H2), packed in passive modified atmosphere (PMA), and stored under refrigeration for up to 40 days to simulate marketing to distant markets. During storage and after three days of shelf-life, the physico-chemical characteristics, damage, and sensory quality of the fruit were analyzed. In general, after cold storage, peaches improve their sensory characteristics after three days at room temperature. PMA with refrigeration was suitable for exporting ‘Rich Lady’ peaches overseas for H1. The late harvest, H2, is recommended for ‘Summer Lady’, as it improves sensory quality without losing storability. ‘Summer Lady’ was the best-rated cultivar by the tasters, and ‘Merryl O’Henry’ the worst, due to its lack of ripening and high incidence of chilling injury.
