Preservative effect of pomegranate-based marination with β-resorcylic acid and cinnamaldehyde on the microbial quality of chicken liver.

Chicken liver is considered a delicacy in the Middle East where pomegranate molass is commonly used as a salad dressing and in marinade recipes. Marinated chicken liver is a common entrée and represents a value-added product compared to the otherwise unmarinated liver which commands a lower price. The aim of this study was to investigate the inhibitory effects of a pomegranate-based marinade alone or following the addition of cinnamaldehyde or β-resorcylic acid on the spoilage microorganisms present in chicken liver during storage for 14 d at 4°C or under mild temperature abuse conditions (10°C).

Food safety knowledge among pregnant women in the United Arab Emirates amid the COVID-19 pandemic.

Inhibition of spoilage bacteria on marinated chicken by essential oils under aerobic and vacuum packaging.

"Chicken tawook" is a marinated boneless chicken entrée consumed in the Middle East. The aim of this study was to determine whether bioactive essential oil (EO) components carvacrol (CA), cinnamaldehyde (CI), and thymol (TH) would delay the growth of microorganisms causing tawook spoilage during aerobic (AP) or vacuum (VP) packed storage. The EOs at 1% and 2% were mixed individually with the marinade.

The demand for marinated chicken worldwide, is continuously growing. To date, limited data on addition of active components of Essential Oils (EOs) to marinades for chicken preservation are available. The antimicrobial effect of carvacrol and thymol, added at 0.

Shelf-life of smoked eel fillets treated with chitosan or thyme oil.

The present study examined the effect of natural antimicrobials: Chitosan, thyme oil and their combination, on the shelf-life of smoked eel fillets stored under vacuum packaging (VP) at 4°C. Based on sensory odor data smoked eel fillets had a shelf-life of 35 (control), 42 (thyme treated and>49 (thyme, chitosan-thyme treated) days. The thiobarbituric acid value (TBA) value of the control eel sample was significantly higher than the chitosan-thyme-treated eel samples.

Use of natural antimicrobials to improve the quality characteristics of fresh "Phyllo" - A dough-based wheat product - Shelf life assessment.

This study explores the effects of chitosan and natamycin on the quality of fresh "Phyllo" - a dough-based wheat product, by monitoring the microbiological, physicochemical and sensory parameters. Four different lots of phyllo samples stored under aerobic packaging conditions, in the absence or presence of the aforementioned antimicrobials, were prepared and stored at 4 °C. Microbiological data suggested that, the combination of chitosan and natamycin resulted in significant reductions (1-3 log cfu/g) of the microbial species examined (mesophilic total viable counts; TVC), yeasts/molds, psychrotrophic and lactic acid bacteria (LAB), Enterobacteriaceae and coliforms) by day 10.

Effects of Citrox and chitosan on the survival of Escherichia coli O157:H7 and Salmonella enterica in vacuum-packaged turkey meat.

In this study, we examined the antimicrobial effects of citrus extract (Citrox(®)) and chitosan on lactic acid bacteria (LAB) and the pathogens Escherichia coli O157:H7 and Salmonella enterica on turkey meat during storage under vacuum packaging (VP) at 4 and 10 °C. We also examined the effects of Citrox and chitosan on pathogen contamination in tryptic soy broth (TSB). Chitosan alone or in combination with Citrox inhibited the growth of endogenous LAB in turkey meat, whereas citrus extract did not cause a major reduction in bacterial density.

Levels of biogenic amines in retail market fermented meat products.

The qualitative and quantitative profile of biogenic amines (BA) in 50 samples of dry fermented sausages sold in Greek retail markets were determined by HPLC. Putrescine, cadaverine, tryptamine, β-phenylethylamine spermidine, spermine were analysed by UV detection after pre-column derivatization with benzoyl chloride, whereas tyramine and histamine were analysed by fluorescence detection after post-column derivatization with o-phthaldialdehyde (OPA). With the exception of spermidine and spermine a wide variation of BA levels was observed among the samples.
