Plasma activated water (PAW) is an effective disinfectant against a wide range of microorganisms, but its effect on food products is limited. This study aimed to investigate the fluid environment on the inactivation efficacy of PAW and its application on fish decontamination. Three organic media (fish gelatin, fish oil, and fish homogenate) at 5%, 10%, and 20%, and inorganic media of phosphate‐...

To improve upon understanding of the quality characteristics of dry‐aged pork, pork belly and arm shoulder were dry aged for 0, 7, 14, 21, and 28 days. Their physicochemical, free amino acids (FAAs) content, and microbiological analysis were performed to evaluate palatability and hygiene. After 28 days of aging, total FAAs content increased by 56.1% and 71.4% for pork belly and arm shoulder,...

The formation of three typical toxic aldehydes malondialdehyde (MDA), 4‐hydroxy‐hexenal (HHE), and 4‐hydroxy‐nonenal (HNE) druing frying were investigated. High contents of them were found in fried foods. Based on the threshold of toxicological concern level suggested by European Food Safety Authority, a simple exposure assessment was conducted. Risks were showed as the consumption of fried foods...

Schematic diagram of Chemiluminescence imaging immunoassay for multiple aminoglycoside antibiotics. Summary A simple and rapid multiplexed direct competitive chemiluminescent (CL) imaging immunoassay had been developed for the simultaneous detection of kanamycin (KAN) and streptomycin (STR), which were widely used against bacterial infections in animals. To achieve the multiplexed detection of...

Increasing shelf life of strawberries by using a banana starch‐chitosan and Aloe Vera edible coating. Summary Strawberries are among the most consumed fruits in the world, however, they are highly susceptible to both microbial and fungal contamination during storage. In this study, we used composite films made from banana starch‐chitosan and Aloe vera gel (AV gel) at different AV gel...

The morphological structure of potato starch‐based biodegradable (PSBB) films with virgin coconut oil (VCO). Increasing VCO concentrations caused a rise in the light transmittance of the films from 2.13 to 4.79 mm−1 and a decrease in water vapour transmittance from 6.77 to 2.12 (10−5 GPa−1 h−1 m−1). Scanning electron microscopy showed that the surface of the film became smoother as VCO...

The authenticity and traceability of meat products are issues of primary importance to ensure food safety. Unfortunately, food adulteration (e.g. the addition of inexpensive cuts to minced meat products) and mislabelling (e.g. the inclusion of meat from species other than those declared) happens frequently worldwide. The aim of this study was to apply a droplet digital PCR assay for the detection...

Texture‐modified foods (TMFs) and thickened fluids have been used as a therapeutic strategy in the management of food intake in the elderly and people with dysphagia. Despite recent advances in describing rheological features of TMFs for dysphagia management, there is still paucity of research regarding the sensory attributes, therapeutic thickness levels, and swallowing safety of these foods....

Physical, chemical and antimicrobial properties of fish gelatin films with different concentrations of ethyl lauroyl arginate (LAE) were studied. Optical properties of film‐forming solution did not vary with increased LAE content. However, pH and surface tension increased. The incorporation of LAE into the formulation increased moisture and solubility of the films. In addition, the presence of...

Alginate‐based edible coating acts as a carrier enabling the sustained release of thyme oil to the surface of the fresh‐cut apples, inhibiting the growth of Listeria monocytogenes, Salmonella Typhimurium, Staphylococcus aureus and Escherichia coli O157:H7 inoculated onto fresh‐cut apples. Summary In this study, the inhibition of an alginate‐based edible coating (EC) containing thyme oil (0.05%, 0...

In some countries, use of horsemeat as a food is inhibited by ethical and cultural concerns. However, horsemeat has potential health benefits, such as low fat and high unsaturated fatty acid content compared with other meats, as well as attractive sensory properties. Although there are many contradictory data on the dietary value in relation to human health, the effects of horsemeat have not been...
