This study was aimed to develop a rapid technique for detection of ochratoxin A (OTA) by Photobacterium leiognathi (P. leiognathi) based on its inhibition of luminescence on P. leiognathi. The freeze‐dried powder of P. leiognathi was incubated and grown aerobically in sterile liquid medium at 28℃ for 20 h. Optical cell density (OD) at wavelength of 610 nm was measured using UV spectrometer every 2 h.

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 studied to a large extent.

Synergistic antimicrobial effect of lactocin AL705 and nisin combined with organic acid salts against Listeria innocua 7 in broth and a hard cheese. Summary The effectiveness of antimicrobial mixtures against Listeria innocua 7, used as a L. monocytogenes surrogate, was investigated in broth and a food system.

CTLE washing exhibited more than 2‐log reductions in the population of L. monocytogenes on romaine lettuce and kale, having similar effects as NaOCl washing. Summary The present study aimed to examine the antimicrobial activity of silkworm thorn (Cudrania tricuspidata) leaf extract (CTLE) and its application as a washing agent for fresh‐cut romaine lettuce and kale.

Impact of increased (+1 °C [‐‐‐]) and decreased (−1 °C […]) temperature on the fate of S. enterica subsp. enterica in raw milk cheese during storage at 5, 15 and 25 °C; [‐] represents fitted model for studied temperatures. Summary The aim of this study was to determine the survival kinetics of Salmonella enterica subsp. enterica in ripened raw milk cheese. Cheese samples inoculated with S. enterica subsp.

Molecular docking is a theoretical simulation method based on bioinformatics and predicts their binding modes and affinity via a computer platform. This review presents the theory and software development of molecular docking, and emphasises its application in the field of food science, including nutritional components and food safety.

In the chicken slices and canned beef B.bacteriovorax induced a E.coli reduction equal to 4.3 and 2.1 logs, respectively, at 6 hours from contamination.♦ E. coli control; ● E. coli test; ▲ Bb control; ■ Bb test. Summary Bdellovibrio bacteriovorus is a predator micro‐organism towards other Gram‐negative bacteria. We tested B. bacteriovorus to control Escherichia coli growth on chicken slices and canned beef.

With single‐copy housekeeping genes based real‐time PCR, the goat meat content in adulterated meat sample with pork could be quantitatively detected by calculating the Ct ratio of goat meat/pork in a wide range 5–80% of goat meat concentration. Summary Adulteration of goat meat with cheaper meat such as pork has been frequently found.

The consumption of resistant starch alone or included in a bread formulation lead to a better gut health as well as an increase in bone mineral content and bone mineral density. Summary The effect of chemically modified resistant starch (RS) included in bread formulation on bone and gut health of growing male Wistar rats was studied.

Light and wounding significantly increase the SGA content in potato tuber during storage. Importantly, they have synergistic effect on SGA content in tuber in this process. Summary Potato tubers contain undesirable steroidal glycoalkaloids (SGAs), which have evoked global concern in terms of feed and food safety due to their toxic effects in humans. The cultivar Unica was exposed to a combination of light and wounding. SGA content among different tissues was analysed.

Okra mucilage powder was revealed its phenolic compounds, antioxidant and antibacterial mode of action, which may be used as a novel functional ingredient. Summary Okra mucilage powder (OMP) was firstly reported its antibacterial mode of action observed by scanning electron microscopy (SEM) and transmission electron microscopy (TEM).
