Abstract Fresh‐cut fruits and vegetables are still an active area of study despite being a staple of food outlets offering minimally processed foods. These minimally processed foods often have a short shelf life due to enzymatic browning. Active packaging is of current interest as it offers an efficient method to deliver polyphenol oxidase inhibitors onto the surface of foods to suppress browning.

Journal of Food Processing and Preservation, Accepted Article. Fresh-cut fruits and vegetables refer to edible commodities that are free from large scale and typical traditional processing operations. However, maintaining their nutritional value and microbiological integrity is challenging. The processing operations such as peeling, cutting and trimming done in the fresh-cut industry can trigger deteriorative reactions such as tissue softening and enzymatic browning.

Journal of Food Processing and Preservation, Accepted Article. Fresh-cut fruits and vegetables are prone to browning that leads to quality decline, low acceptability and food waste. Therefore, it is of great importance to study and alleviate the browning of fresh-cut fruits and vegetables. Plant extracts, rich in bioactive compounds like polyphenols, flavonoids, terpenes and other active ingredients, exhibit high antioxidant and anti-browning ability.

The treated fresh-cut kiwi samples were evaluated in terms of color, enzyme activities, bioactive compounds, microbial and sensory studies.

Various fruits are involved in food models, including fresh‐cut fruit, fruit salad, and juices. Toxigenic fungi in horticulture have attracted interest in order to the food safety requirements and their illnesses relation. This study aimed to apply grape by‐products (Gbps) that contain bioactive compounds to reduce mycotoxin and limit toxigenic fungal‐activity in fresh‐cut fruit and juice. The Gbps were collected and extracted using ultra‐sonication.

The present study aimed to examine the efficiency of ethanolic extract of Capsicum annuum L (CAE) in improving the shelf life and quality of fresh‐cut C. annuum (FCCa). The uniformly sliced FCCa were prewashed with sodium hypochlorite solution (NaOCl) and then treated with 10% of CAE. The foodborne pathogens of Listeria monocytogenes and Salmonella enterica were patched on the surface of FCCa and stored at 15°C and 4°C for 12 days.

In this study, two near neutral pH electrolysed water (NEW1 produced by redirecting of the catholyte solution back to the anode chamber and NEW2 produced by using NaCl and NaHCO3 as electrolyte) and control (NEW0, produced by commercial unit) were evaluated for their stability during 75 h storageat 7°C.

Today's consumers prefer foods that are practically prepared and ready for consumption. Therefore, global demand for the consumption of minimally processed fruits gained popularity. In this study, the use of quince (Cydonia oblonga) seed mucilage was investigated as an edible coating to extend the shelf life of mandarin fruit ready for consumption. The mucilage obtained from the quince seed extract was used for covering the mandarin slices and samples were stored at 4°C for 10 days.

In the current study, fresh‐cut broccoli was soaked in melatonin solution before cold storage (4°C, 95% RH) for 25 days. The results indicated that 100 µM melatonin treatment inhibited the increase of L* and b* values and retained higher hue angle, total chlorophyll content, and fresh weight during storage.
