Background: In Florida, tomatoes are harvested green (GR), which includes mature green (MG) and immature green (IG) fruits, and stored at low temperature (13 °C), resulting in poor flavour. Flavour improvement might be achieved if fruits were harvested with some colour (to eliminate IG fruits) and/or stored at higher temperature with the ripening inhibitor 1-methylcyclopropene (1-MCP).
Results: 'Florida 47' tomatoes were harvested at GR (MG + IG), breaker (BR), turning (TR) and pink (PK) stages, treated (+) or not (-) with 1-MCP and stored at 13 and/or 18 °C. 1-MCP treatment resulted in a gain of up to 6 days of shelf life depending on harvest maturity and storage temperature. Storage at 18 °C rather than 13 °C resulted in an increase in internal red colour, soluble solids (SS)/titratable acidity (TA) ratio and levels of many volatiles studied. The shelf life of BR (+) MCP fruits stored at 13 °C was similar to that of MG fruits. IG fruits exhibited lowest levels of SS, TA and ten volatiles compared with BR fruits.
Conclusion: Harvesting tomatoes with colour (BR), thereby eliminating IG fruits, and treating with 1-MCP resulted in better quality with adequate shelf life.

Protein modification/immobilization has been introduced as a large toolbox for creating a myriad of engineered proteins with profound implications for various scientific and industrial applications. Proteins immobilization techniques are generally performed through protein fixation in/to heterogeneous materials or via inter cross-linking of protein molecules, enabling the development of biocatalysts, biosensors, and drug delivery systems. On the other hand, chemical modification of proteins offers tailored changes in their functionality, enhances protein performance, extends their shelf life, and enables their specific binding interactions.

Background: Produced naturally by lactic acid bacteria, L-lactic acid is found in many fermented milk products and also in pickled vegetables, cured meats and fish. It serves as a quality parameter in wine, beer, whole egg, whole egg powder, and juices.
Objective: To validate the performance of the Enzytec™ Liquid L-Lactic acid for the determination of L-lactic acid in food and beverages such as milk and (fermented) milk products, fermented vegetable products, wines, beer, fruit and vegetable juices, egg and egg powder.
The study evaluated the effects of chitosan coating combined with Orange () essential oil (OEO) and potassium permanganate (KMnO) sachets as ethylene inhibitors on maintaining quality and extending the shelf-life of Ercolini pears. Additionally, it examined the reduction of superficial scalding in pears stored at 25°C ± 2°C. for 14 days.

Mango (Mangifera indica L.), a climacteric fruit, undergoes rapid ripening driven by ethylene signaling, which plays a crucial role in modulating ascorbic acid (AsA) metabolism. AsA biosynthesis is primarily governed by the L-galactose pathway, with GDP-L-galactose phosphorylase (MiGalDH) catalyzing a key step.

Mandarin oranges are susceptible to senescence and decay, primarily due to postharvest quality loss and fungal infections. This study aim to develop edible and active coatings using carnauba and shellac incorporated with carvacrol nanoemulsion (CNE), and to examine the synergistic effects of the coating on the quality parameters and shelf-life of the mandarin oranges during ambient storage. Nanoemulsion of carvacrol with average droplet size of 348.
