Edible button mushroom () is the most common commercial-grade mushroom in the world. The shelf life of button mushrooms is limited to a range between two and four days because of enzymatic browning at medium ambient temperature if it is minimally processed. This study aimed to investigate the effects of power ultrasonics and its interaction with several treatments including HO and O on increasing the storage quality of edible button mushroom by controlling enzymatic browning. A 100 W ultrasonic bath with a frequency between 20 and 35 kHz was used during the experiments. The storage quality was studied by examining the changes in color and microbial content over 12 days. The results obtained from the digital image processing and total microbial counting showed that the ultrasonic treatment for 6 min is an appropriate method for controlling the color preservation of mushrooms to improve their shelf life. The maximum changes in RGB band, HSV band, L*a*b* band, and microbial content of the mushroom samples under the ultrasonic treatment were equal to 7%, 12%, 10%, and 11%, respectively. Furthermore, having the color properties and microbial content of the samples, the artificial neural network (ANN) was capable of predicting their storage period with an of 0.011.

The present study intended to investigate the properties of collagen peptide (CP)-astragaloside (AG) nanocomplexes (CPANs) improved oxidized hydroxypropyl starch (OHS)/chitosan (CS) (OC) film and to explore the preservation of chilled beef. The results indicated that AG significantly enhanced the stability, antioxidant capacity, and antibacterial properties of CP through mechanisms like static quenching and hydrophobic interactions. The incorporation of CPANs improved thickness, swellability, and water vapor blocking, UV-blocking and mechanical properties, antioxidant and antibacterial activity of OC film.

Avocado (Persea americana Mill) is a climacteric fruit harvested at the green stage that ripens postharvest to become edible. The 'Hass' cultivar, known for its rich, buttery flavor and pear-shaped appearance, was studied for metabolite changes during postharvest ripening using UPLC-MS/MS approach. The 16-day ripening period could be divided into three stages: evolution (days 1-9), edible ripe (days 10-15) and overripe (day 16).

Methicillin-resistant (MRSA) is a refractory pneumonia-causing pathogen due to the antibiotic resistance and the characteristics of persisting inside its host cell. Lysostaphin is a typical bacteriolytic enzyme for degrading bacterial cell walls via hydrolysis of pentaglycine cross-links, showing potential to combat multidrug-resistant bacteria. However, there are still grand challenges for native lysostaphin because of its poor shelf stability and limited bioavailability.

Traditionally, food packaging was used to extend the shelf life of food or to monitor its condition. Inspired by many biological structures found in nature, bio-inspired functional materials for bio-based food packaging have been shown to have significantly improved capabilities over traditional bio-based food packaging materials in various aspects and to attract consumers through novel freshness preservation features. This review synthesizes recent advances in bio-inspired bio-based food packaging materials that mimic the structure of natural organisms with specific functionalities, with examples of specific biomimetics in different enhancement areas.

Although traditional petroleum-based packaging materials pose environmental problems, biodegradable packaging materials have attracted extensive attention from research and industry for their environmentally friendly properties. Bio-based films, as an alternative to petroleum-based packaging films, demonstrate their significant advantages in terms of environmental friendliness and resource sustainability. This paper provides an insight into the development of biomass food packaging films such as cellulose, starch, chitosan, and gelatine, including their properties, methods of preparation (e.
