AI Article Synopsis
- Adding essential oils to an edible coating could help the food industry combat foodborne pathogens, especially in berries.
- A study evaluated the effectiveness of a coating containing carvacrol and citral on reducing dangerous bacteria and viruses in frozen strawberries and blueberries.
- Results showed significant reductions in bacteria and Norovirus infectivity over time, with strawberries showing the highest effectiveness after eight weeks of storage.
Article Abstract
Adding essential oils in an edible coating could be an alternative for the food industry to control foodborne pathogens. In 2014, EFSA published a report highlighting the risk associated with spp. and Norovirus in fresh and frozen berries. This study aimed to evaluate the efficacy of an edible coating (RP-7) with carvacrol and citral on reducing the population of , O157:H7, , and murine Norovirus (MNV-1) in frozen strawberries and blueberries. Before evaluating the efficacy, the best method for applying the coating on fruit was studied. The immersion method was selected, with an optimal drying time of 45 min. After this, the berries were frozen and stored for one, two, three, four, and eight weeks at -18 °C. In strawberries, all bacteria were reduced to below 0.7 log cfu/strawberry in the eighth week, and the MNV-1 infectivity showed a reduction of nearly 2 logarithmic units. In blueberries, and O157:H7 were reduced to 0.8 log cfu/blueberries within a week, and MNV-1 achieved a reduction of 0.8 logarithmic units at the end of the assay. The application of RP-7 affected the studied microorganisms in frozen strawberries and blueberries.

Lipid and protein oxidation have significant effects on the shelf-life and nutritional value of meat and meat products. While lipid oxidation has been extensively studied, it has been recognized that proteins are also susceptible to oxidation. However, the precise mechanisms of oxygen-induced amino acid and protein modifications in the food matrix remain unclear.

Most photosensitizers have limited responsiveness to visible light, however, visible light is a light source with a wide range of wavelengths and the most common in daily life, and making full use of visible light can help to enhance the photodynamic antimicrobial properties of photosensitizers. To tackle this issue, this study confirmed that alizarin has a good absorption capacity for visible light by UV-DRS analysis. Theoretical calculations showed that alizarin might be excited through the charge transfer (CT) mechanism.

The development of safe, environmentally friendly, edible antimicrobial packaging films represents a promising alternative to conventional plastic packaging for reducing spoilage and extending the shelf life of fresh food. Here, we propose a novel strategy to construct edible β-CD-MOF/carvacrol@zein (BCCZ) composite films by intertwining β-CD-MOF loaded with the antimicrobial essential oil carvacrol, and zein. The resulting BCCZ films exhibit high humidity-triggered, long-lasting bactericidal efficacy, effective fruit preservation, and excellent biosafety.

Microplastics (MPs) and other anthropogenic particles (APs) are pervasive environmental contaminants found throughout marine and aquatic environments. We quantified APs in the edible tissue of black rockfish, lingcod, Chinook salmon, Pacific herring, Pacific lamprey, and pink shrimp, comparing AP burdens across trophic levels and between vessel-retrieved and retail-purchased individuals. Edible tissue was digested and analyzed under a microscope, and a subset of suspected APs was identified using spectroscopy (μFTIR).
