Role of Lactic Acid Bacteria in Food Preservation and Safety

Foods, Journal Year: 2022, Volume and Issue: 11(9), P. 1283 - 1283

Published: April 28, 2022

Fermentation of various food stuffs by lactic acid bacteria is one the oldest forms biopreservation. Bacterial antagonism has been recognized for over a century, but in recent years, this phenomenon received more scientific attention, particularly use strains (LAB). Certain LAB demonstrated antimicrobial activity against foodborne pathogens, including bacteria, yeast and filamentous fungi. Furthermore, many authors proved that have ability to neutralize mycotoxin produced last group. Antimicrobial mainly based on production metabolites such as acid, organic acids, hydroperoxide bacteriocins. In addition, some research suggests other mechanisms pathogens well their toxic metabolites. These properties are very important because future possibility exchange chemical physical methods preservation with biological method Biopreservation defined extension shelf life increase safety controlled microorganisms or This may determine alternative usage preservatives. study, possibilities provided. Our aim yield knowledge about fermentation pathogenic microorganisms. we would like introduce actual information health aspects associated consumption fermented products, probiotics.

Modulatory Effects of Probiotics During Pathogenic Infections With Emphasis on Immune Regulation

Frontiers in Immunology, Journal Year: 2021, Volume and Issue: 12

Published: April 8, 2021

In order to inhibit pathogenic complications and enhance animal poultry growth, antibiotics have been extensively used for many years. Antibiotics applications not only affect target pathogens but also intestinal beneficially microbes, inducing long-lasting changes in microbiota associated with diseases. The application of has other side effects like, barrier dysfunction, residues foodstuffs, nephropathy, allergy, bone marrow toxicity, mutagenicity, reproductive disorders, hepatotoxicity carcinogenicity, antibiotic-resistant bacteria, which greatly compromise the efficacy antibiotics. Thus, development new is necessary, while search antibiotic alternatives continues. Probiotics are considered ideal substitute; recent years, probiotic research concerning their during infections humans, aquaculture, poultry, livestock industry, emphasis on modulating immune system host, attracting considerable interest. Hence, adverse remedial probiotics infectious diseases become central points focus among researchers. live microorganisms, when given adequate quantities, confer good health host through different mechanisms. Among them, regulation response one most important A number studies investigated aspects probiotics. this review, we mainly summarize discoveries discuss two aspects: (1) infections; (2) modulatory non-infectious

Encapsulation of probiotics: past, present and future

Beni-Suef University Journal of Basic and Applied Sciences, Journal Year: 2022, Volume and Issue: 11(1)

Published: April 5, 2022

Abstract Background Probiotics are live microbial supplements known for its health benefits. Consumption of probiotics reported to improve several benefits including intestinal flora composition, resistance against pathogens. In the recent years, there is an increasing trend probiotic-based food products in market. Main body cells targeted reach large intestine, and must survive through acidic conditions gastric environment. It recommended formulate probiotic bacteria range 10 8 –10 9 cfu/g consumption maintain therapeutic efficacy 6 7 intestine. During gastrointestinal transit, will drastically lose viability environment (pH 2). Maintaining cell until it reaches intestine remains challenging task. Encapsulating with suitable wall material helps sustain survival during industrial processing transit. encapsulation process, completely enclosed material, different techniques spray drying, freeze extrusion, emulsification, etc. However, spray-drying freeze-drying successfully used commercial formulation; thus, we limited review those techniques. Short conclusions The rate spray-dried simulated digestion mainly depends on inlet air temperature, exposure GI condition. And fermentation, pH time important process parameters maintaining bacterial Improving extending storage be main concern successful commercialization. Graphical abstract

Poor diet, obesity and a sedentary lifestyle have significant impact on natural microbiota disorders; specifically, the intestinal one. This in turn can lead to multitude of organ dysfunctions. The gut contains more than 500 species bacteria constitutes 95% total number cells human body, thus contributing significantly host’s resistance infectious diseases. Nowadays, consumers turned purchased foods, especially those containing probiotic or prebiotics, that constitute some functional food market, which is constantly expanding. Indeed, there are many products available incorporate probiotics, such as yogurt, cheese, juices, jams, cookies, salami sausages, mayonnaise, nutritional supplements, etc. probiotics microorganisms that, when taken sufficient amounts, contribute positively health host focus interest for both scientific studies commercial companies. Thus, last decade, introduction DNA sequencing technologies with subsequent bioinformatics processing contributes in-depth characterization vast biodiversity microbiota, their composition, connection physiological function—known homeostasis—of organism, involvement several Therefore, this study, we highlighted extensive investigation current research association types foods prebiotics diet composition microbiota.
