“…As a result, the development of non-dairy alternatives based on fruit and vegetables, such as probiotic fresh-cut fruits, could serve as a preference vector for these consumers [4]. 'Minimally processed', 'ready-to-eat', 'fresh-cut', and some other designations indicate fruits ready for consumption [5], categories that have growing popularity attributable to their convenience, sensory quality, excellent nutritional value, and ability to retain freshness [6]. Recently, probiotic addition was proposed for a growing number of fresh-cut fruits, such as apples, pears, cantaloupes, pineapples, carrots, and blueberries [7][8][9][10][11][12].…”

The use of lactic acid bacteria (LAB) for the probiotic enrichment of minimally processed fruit is a well-established practice in the literature. In addition, several LAB demonstrated a strain-specific ability to control harmful microorganisms and decay agents, improving shelf life, maintaining quality, and promoting the safety of fruits and vegetables. Edible coatings can help modulate the phenomena of gas exchange and water loss by fruits, representing protection from physical damage and spoilage phenomena linked to oxidation and the development of undesired microorganisms. At the same time, the coating can represent an innovative delivery matrix for the LAB strains of potential interest to improve safety and quality in the postharvest management of fruits. In this work, five Lactiplantibacillus plantarum strains, previously characterised for their probiotic and antifungal activity, were incorporated into a sodium alginate coating to develop edible probiotic coatings with antifungal properties for table grapes cv. Italia. The bacterial transfer and their survival were evaluated by comparing coated and uncoated table grapes during 14 days of cold storage at 4 °C. The alginate edible coating increased the number of viable cells transferred to the surface of the berries from about 5 to more than 7 Log CFU/g, with a crucial impact on the potential functional attributes of the final product. The ability of the functionalised coatings to counteract the decay development was evaluated on table grape berries artificially contaminated with Aspergillus niger CECT 2805. A significant reduction in lesion diameter was observed in the alginate coating with L. plantarum 11-A, with a reduction from 15.40 ± 1.14 mm of uncoated berries to 8.40 ± 1.14 mm of berries coated with L. plantarum 11-A. The lesion diameter reduction was also accompanied by a reduction in the symptoms of infection, such as browning around the wound. These results suggest the application of selected strains of L. plantarum as promising bio-resources to enhance the overall value of ready-to-eat fruits and vegetables, particularly in combination with edible coating as a carrier matrix. While a strain-dependent effect was not detected with respect to the improvement in the number of cells in the edible coating, a variability depending on the biotype used was detected for the properties linked to biocontrol, suggesting that the inclusion in edible packaging may represent an innovative criterion in the selection of lactobacilli to be applied postharvest.

Several meta-analyses have consistently demonstrated that the consumption of an adequate level of fruit and vegetables (F&V), along with other food groups, is associated with a low risk of all-cause mortality, and, as such, represents one of the major modifiable risk factors related to the growing burden of Non-Communicable Diseases (NCDs). The aim of the present narrative review was to provide an up-to-date analysis of systematic reviews and meta-analyses published in the past five years, dealing with the effects of F&V consumption on human health, focusing on specific pathologies, such as total mortality, cancer, cardiovascular diseases (CVDs), type 2 diabetes, intestinal inflammation, and bone and respiratory illnesses. The results of our evaluation confirmed and consolidated the protective role of F&V consumption against the development of NCDs, especially CVDs. However, the need to corroborate existing evidence and clarify the role of confounding factors by performing additional randomized control trials and adopting more standardized approaches and study designs also emerged. Moreover, evaluating the protective role of fruit and vegetables as separate food categories appeared to be one of the most interesting areas to investigate in the near future. Overall, these outcomes could help in addressing future research to better establish a causal relationship between F&V consumption and human health.
