TL;DR: The characteristics and advantages of sheep Milk as a potentially functional food, as well as the development of sheep milk dairy products containing prebiotics and/or probiotics are addressed.
Abstract: Sheep milk has a high nutritional value and high concentrations of proteins, fats, minerals, and vitamins, as compared to the milks of other domestic species. The physicochemical and nutritional characteristics of sheep milk can be advantageous for the manufacture of products containing prebiotic ingredients and/or probiotic bacteria, which are major categories in the functional food market. Following this technological trend, this review will address the characteristics and advantages of sheep milk as a potentially functional food, as well as the development of sheep milk dairy products containing prebiotics and/or probiotics.

TL;DR: Three main classes of probiotic are proposed including ‘true probiotic’ (TP) referring to viable and active probiotic cell, ‘pseudo-probiotic” (PP) referringto viable and inactive cell, in the forms of vegetative or spore (PPV or PPS) and ‘ghost probiotic ‘ (GP) referringTo provide mentioned comprehensive approach and terminology for all aspects of probiotics benefits.
Abstract: According to the proposed definition by FAO/WHO, probiotics must be alive and abundant once ingested. However, during recent years, new definitions are added to the probiotic terminology such as ‘paraprobiotics’ (dead/inactive cells of probiotics) and ‘postbiotics’ (healthful metabolites of probiotics), because findings have shown that dead cells (intact or ruptured) could also show significant health impacts on human. However, mentioned terms are not accurate and impressive enough to reflect the intended meanings regarding all states of probiotic benefits and it seems that a disturbance and confusion in probiotic glossary has been occurred. As a result, a new terminology based on a new efficient approach and conceptualization is needed for a global agreement and usage. In the present paper, we are honored to propose such terminology to provide mentioned comprehensive approach and terminology for all aspects of probiotic benefits. We are proposing three main classes of probiotic including ‘true probiotic’ (TP) referring to viable and active probiotic cell, ‘pseudo-probiotic’ (PP) referring to viable and inactive cell, in the forms of vegetative or spore (PPV or PPS) and ‘ghost probiotic’ (GP) referring to dead/nonviable cell, in the forms of intact or ruptured (GPI or GPR). Each of these classes are classified into two groups based on their site of action/impact: internal (in vivo) or external (in vitro).

TL;DR: This article reviews the principles of microencapsulation of the probiotic cells, one of the newest and highly efficient methods, which is now under the especial attention and is being developed by various researchers.
Abstract: Worldwide popularity of probiotic- microorganisms and their products on the one hand, and their general weak viability in food products (especially fermented types) as well as gastrointestinal conditions on the other hand, has encouraged researchers to innovate different methods of probiotics viability improvement. Microencapsulation of the probiotic cells is one of the newest and highly efficient methods, which is now under the especial attention and is being developed by various researchers. This article reviews the principles

TL;DR: The viability of probiotic organisms in cheese as well as the main factors influencing their stability during processing and storage are reviewed.
Abstract: Cheese is a dairy product which has a good potential for delivery of probiotic microorganisms into the human intestine due to its specific chemical and physical characteristics compared to fermented milks (higher pH value and lower titrable acidity, higher buffering capacity, greater fat content, higher nutrient availability, lower oxygen content, and denser matrix of the texture). In addition, a large variety of cheese types all over the world, consumption of cheese by everybody in their long-term diet, as well as the nutritional value of cheese have resulted in regular market growth for probiotic cheeses. To be considered to offer probiotic health benefits, probiotics must remain viable in food products above a threshold level (e.g., 106 cfu g−1) until the time of consumption, without adversely altering sensory attributes. Therefore, incorporation of probiotic cells into different cheese matrices and studying the influences of different compositional and process factors affecting the viability of probiotics in this product as well as its sensory properties have been the subject of numerous studies. Factor influencing the stability of probiotics in cheese can be categorized into three areas including formulation factors (strains of probiotic bacteria and microbial interactions, pH and titrable acidity, hydrogen peroxide, molecular oxygen, growth promoters and food additives, salt, microencapsulation, and ripening factors), process factors (incubation temperature, heat treatment, types of inoculation, and storage temperature), and packaging materials and systems. This article reviews the viability of probiotic organisms in cheese as well as the main factors influencing their stability during processing and storage.

TL;DR: The potential application of essential oils as natural antimicrobial agents for reduction of common spoilage and pathogenic bacteria as well as molds and yeasts in cheese-making industry is introduced.
Abstract: Increasing demand of consumers to use food products without preservatives or natural preservatives as possible has compelled the food industries for utilization of preservatives with herbal and microbial origins instead of artificial preservatives in their production. Essential oils are volatile, natural plant-derived substances that are used in medicine, food flavoring and food preservation. These diverse compounds represent considerable potential antioxidant, antibacterial and antifungal activities via various mechanisms. This review represents an overview on the impact of essential oils and their constituents as natural antimicrobials versus common pathogenic and spoilage microorganisms in cheese along with the related mechanisms of actions. Industrial relevance Natural preservatives have proven popularity such that interest continues in substituting artificial additives with natural. Therefore, production of safe food without or with low amounts of synthetic preservatives is one of the most important challenges in the food industry. This review, introduces the potential application of essential oils as natural antimicrobial agents for reduction of common spoilage and pathogenic bacteria as well as molds and yeasts in cheese-making industry.
