Functional Properties of Microorganisms in Fermented Foods

1st Edition

Fermentation in food processing is the process of converting carbohydrates to alcohol or organic acids using microorganisms — yeasts or bacteria —under anaerobic conditions. Fermentation usually implies that the action of microorganisms is desired.

Fermented foods have unique functional properties imparting some health benefits to consumers due to presence of functional microorganisms, which possess probiotics properties, antimicrobial, antioxidant, peptide production, etc. Health benefits of some global fermented foods are synthesis of nutrients, prevention of cardiovascular disease, prevention of cancer, gastrointestinal disorders, allergic reactions, diabetes, among others. The present paper is aimed to review the information on some functional properties of the microorganisms associated with fermented foods and beverages, and their health-promoting benefits to consumers. Existing scientific data show many fermented foods have both nutritive and non-nutritive components in foods, which have the potential to modulate specific target functions in the body relevant to well-being and health of the consumers. Naturally fermented foods and beverages contain both functional and non-functional microorganisms Tamang et al. Among bacteria associated with fermented foods and alcoholic beverages, lactic acid bacteria LAB mostly species of Enterococcus , Lactobacillus , Lactococcus , Leuconostoc , Pediococcus , Weissella , etc. Species of Bacillus are also present in legume-based fermented foods Kubo et al.

Fermented foods play a major role in the diet of people in Africa, where a wide variety of raw materials are fermented.

Phisicochemical, sensory, and microbiological evaluation and development of symbiotic fermented drink. The goal of this study was to develop a symbiotic lacteous drink, evaluate its physicochemical and sensory characteristics, and verify the viability of Lactobacillus acidophilus in the drink. It was stored for up to 21 days under refrigeration. The milk serum-based drink was analyzed for protein, ether extract, total dietary fiber, total frutans, carbohydrate content, color, pH, acidity, and contamination by coliforms, and Salmonella sp. Coliforms and Salmonella sp were not detected, and L. Lactobacillus acidophilus resistance to gastric acids and bile salts was detected only up to seven days of storage when evaluated in vitro.

While many food science programs offer courses in the microbiology and processing of fermented foods, no recently published texts exist that fully address the subject. Food fermentation professionals and researchers also have lacked a single book that covers the latest advances in biotechnology, bioprocessing, and microbial genetics, physiology, and taxonomy. In Microbiology and Technology of Fermented Foods , Robert Hutkins has written the first text on food fermentation microbiology in a generation. This authoritative volume also serves as a comprehensive and contemporary reference book. A brief history and evolution of microbiology and fermented foods, an overview of microorganisms involved in food fermentations, and their physiological and metabolic properties provide a foundation for the reader.

Fermented foods are consumed all over the world and show increasing trends. They play many roles, from preservation to food security, improved nutrition and social well-being. Different microorganisms are involved in the fermentation process and the diversity of the microbiome is high. Varzakas et al. They highlighted soybean tempe and other soybean paste products, sauerkraut, fermented olives, fermented cucumber and kimchi.

Functional Properties of Microorganisms in Fermented Foods

Fermented foods have been consumed for centuries across the globe. Recently, they have become trendy. What exactly are fermented foods? Are they good for our health? Fermented foods have been produced and consumed since the beginning of civilization.

Fermented Foods in Health and Disease Prevention is the first scientific reference that addresses the properties of fermented foods in nutrition by examining their underlying microbiology, the specific characteristics of a wide variety of fermented foods, and their effects in health and disease. The current awareness of the link between diet and health drives growth in the industry, opening new commercial opportunities. Coverage in the book includes the role of microorganisms that are involved in the fermentation of bioactive and potentially toxic compounds, their contribution to health-promoting properties, and the safety of traditional fermented foods. Authored by worldwide scientists and researchers, this book provides the food industry with new insights on the development of value-added fermented foods products, while also presenting nutritionists and dieticians with a useful resource to help them develop strategies to assist in the prevention of disease or to slow its onset and severity. She currently heads a team at the Institute of Food Science Technology and Nutrition, Madrid, Spain, carrying out research on the production and characterization of biologically active ingredients from plant food origin.

While the process of fermentation significantly predates the emergence of our species, humans have been harnessing this microbial technology for food production and preservation for thousands of years. Here, we will dive into the history and science of fermented foods. A portion of an ancient Egyptian artifact depicting grape cultivation and winemaking. In the culinary sense, fermentation is the transformation and preservation of food by bacteria. While the process of fermentation as a culinary practice dates back to early human civilization, it took a very long time before the scientific principles were understood 1.

Fermented foods for health?

While the focus of most of the workshops was decidedly modern, one of the workshops I had the pleasure of attending was centered on fermentation. This post will hopefully serve as a very basic history of the process and an introduction to some general principles of how it works.

Сьюзан знала, что без ТРАНСТЕКСТА агентство беспомощно перед современным электронным терроризмом. Она взглянула на работающий монитор. Он по-прежнему показывал время, превышающее пятнадцать часов. Даже если файл Танкадо будет прочитан прямо сейчас, это все равно будет означать, что АНБ идет ко дну.

Он достал пистолет. Он выдвинул два стула на середину комнаты. Сел. Поднял посверкивающую полуавтоматическую беретту и нацелил ее на дверь, а потом опустил себе на колени. - Сьюзан, - сказал он торжественно.  - Здесь мы в безопасности.

Он жертвует всеми планами, связанными с Цифровой крепостью. Хейл не мог поверить, что Стратмор согласился упустить такую возможность: ведь черный ход был величайшим шансом в его жизни. Хейлом овладела паника: повсюду, куда бы он ни посмотрел, ему мерещился ствол беретты Стратмора.
