Zinc oxide nanomaterials: Safeguarding food quality and sustainability.

In this era, where food safety and sustainability are paramount concerns, the utilization of zinc oxide (ZnO) nanoparticles (NPs) is a promising solution to enhance the safety, quality, and sustainability of food products. ZnO NPs in the food industry have evolved significantly over time, reflecting advancements in synthesizing methods, antimicrobial activities, and risk assessment considerations for human health and the environment. This comprehensive review delves into the historical trajectory, current applications, and prospects of ZnO NPs in food-related contexts.

A novel Lactiplantibacillus plantarum strain: probiotic properties and optimization of the growth conditions by response surface methodology.

The objective of this study is to explore the probiotic properties and optimal growth conditions of Lactiplantibacillus plantarum BG24. L. plantarum BG24 exhibited a remarkable ability to utilize lactose, and to grow under acidic conditions and in the presence of high levels of bile salts.

In Vivo Investigation of Supportive Immunotherapeutic Combination of Bifidobacterium infantis 35624 and Doxorubicin in Murine Breast Cancer.

The aim of the study is to investigate the anti-tumor effect of Bifidobacterium infantis 35624 in a xenograft model in BALB/c mice injected with 4T1 cells as a support for chemotherapeutic treatments of doxorubicin in vivo. The MTT assay was used to determine the cytotoxicity of doxorubicin against cancer cells, and apoptosis was analyzed by using flow cytometry. 4T1 cells (2 × 10 cells/mouse) were injected to BALB/c mice, and mice were fed with/without gavage B.

Investigation of the supportive therapy potential of propolis extract and Lactobacillus acidophilus LA-5 milk combination against breast cancer in mice.

Immunotherapy has been applied in cancer treatments for many years as an alternative treatment method to radiotherapy, chemotherapy. It is well known that immunotherapy could suppress tumor formation by modulating the immune system of the host. The aim of the study is to investigate supportive therapy potential of acidophilus milk (AS) and propolis extract (PE) in the mouse xenograft breast cancer model.

A portable microfluidic platform for rapid determination of microbial load and somatic cell count in milk.

Microfluidics systems that have been emerged in the last 20 years and used for processing the fluid in a microchannel structure at microliter levels are alternative to the conventional methods. The objective of the study is to develop a microfluidic platform for determination of the microbial load and the number of somatic cells in milk. For this purpose, a polydimethylsiloxane (PDMS) chip with a channel size of 300 μm × 60 μm was produced.

Production of crispy bread snacks containing chicken meat and chicken meat powder.

Chicken meat in two different forms (chicken meat and chicken meat powder) were added into white flour and whole wheat blend baguette bread formulations for protein enrichment and finally developing new and healthy snacks. The chicken meat and powder levels were 10% for white flour baguette, and 15% for whole wheat blend. The dried baguette samples were packaged under 100% N2, and physical, chemical, microbiological and sensorial properties were evaluated during 3 months of storage.

Antimicrobial effect of sour pomegranate sauce on Escherichia coli O157:H7 and Staphylococcus aureus.

Pomegranate sauce is one of the most popular pomegranate products produced in Turkey. This study was conducted to determine the minimum inhibitory concentrations (MICs) of both traditional and commercial sour pomegranate sauce samples on Staphylococcus aureus (ATCC 25923) and Escherichia coli O157:H7 (ATCC 43895). The initial microflora of the pomegranate sauce samples was determined by performing the enumerations of total aerobic mesophilic bacteria, yeast and mold, S.

Inhibitory effect of sour pomegranate sauces on some green vegetables and kisir.

In this study, the antimicrobial effects of both traditional and commercial pomegranate sour sauce samples on some green vegetables and also on "kısır" which is a popular and traditional appetizer in Turkey were investigated. The inhibitory effect of the pomegranate products on the naturally existing bacterial microflora of lettuce, spring onion, parsley and kısır were analyzed. Also, all these food samples were inoculated with Staphylococcus aureus (ATCC-25923) and Escherichia coli O157:H7 (ATCC-43895) and antimicrobial effect of the pomegranate products on the inoculated microflora was detected.

Marination of deep-water pink shrimp with rosemary extract and the determination of its shelf-life.

The effect of the antioxidant activity of rosemary extract on marinated deep-water pink shrimp (Parapenaeus longirostris Lucas, 1846) stored at 1°C was investigated. Chemical, physical, instrumental, microbiological and sensory analyses were performed to investigate the quality changes and to determine the shelf-life of marinated shrimps. Chemical composition of the shrimp was determined and no significant difference (P>0.

Microbiological evaluation of stuffed mussels.

Stuffed mussel is a traditional food, sold by street vendors in coastal parts of Turkey and other Mediterranean countries. In the present study, the microbiological quality of not only the stuffing mixture, but also the outer surface of the stuffed mussels was evaluated for 1 year, and the effect of the ambient temperatures on the prevalence and the count levels of the microorganisms were evaluated. Fifty samples (750 stuffed mussels in total) were collected periodically, and microbiological analyses were performed by standard procedures for aerobic plate count, coliforms, fecal coliforms, Enterobacteriaceae, Staphylococcus aureus, Bacillus cereus, and Vibrio spp.

Effectiveness of lemon juice in the elimination of Salmonella Typhimurium in stuffed mussels.

Street foods are becoming more and more prominent in countries all over the world. There are many reports of disease due to consumption of street foods contaminated by pathogens. With the modern trend toward more natural preservatives, the use of organic acids can achieve a good microbiological safety in food.

Isolation and identification of a Paenibacillus polymyxa strain that coproduces a novel lantibiotic and polymyxin.

A new bacterial strain, displaying potent antimicrobial properties against gram-negative and gram-positive pathogenic bacteria, was isolated from food. Based on its phenotypical and biochemical properties as well as its 16S rRNA gene sequence, the bacterium was identified as Paenibacillus polymyxa and it was designated as strain OSY-DF. The antimicrobials produced by this strain were isolated from the fermentation broth and subsequently analyzed by liquid chromatography-mass spectrometry.
