Abstract
The objectives of the study were to improve the functionality of fermented salami using probiotics, to evaluate the effects of the addition of probiotics on the physicochemical and microbiological characteristics and sensory acceptance of fermented salami, and to introduce a brand-new probiotic food to the market for meat products. Fermented salami samples were produced using various formulations, including no probiotic (A), non-probiotic starter cultures (B) or probiotic cultures [Lacticaseibacillus rhamnosus LR32 200B (C), Lactiplantibacillus plantarum LP115 400B (D), Bifidobacterium lactis BB12 (E), and L. rhamnosus LR32 200B + L. plantarum LP115 400B (F)]. The samples were kept at 4°C for 60 days, and their probiotic viability as well as their chemical, physical, microbiological, and sensory qualities were assessed at intervals of 0, 15, 30, 45, and 60 days. The probiotic addition enhanced the safety and quality of the product while favorably affecting the microbiological, physical, chemical, and sensory properties of the samples. The sample produced with mixed probiotics (F) had the highest moisture and fat content and the lowest pH. Lactic acid bacteria counts were found above 6.0 log CFU/g in the samples produced with probiotic at the end of the storage. Probiotic added products were rated higher than products without probiotics in terms of color, texture, flavor, and overall acceptance during storage. Consequently, a probiotic fermented salami with high probiotic cell counts and meeting the sensory preferences of the consumers was produced.

Bifidobacterium species viability in dairy-based probiotic foods: challenges and innovative approaches for accurate viability determination and monitoring of probiotic functionality. Front Microbiol 2024; 15:1327010. [PMID: 38371928 PMCID: PMC10869629 DOI: 10.3389/fmicb.2024.1327010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2023] [Accepted: 01/15/2024] [Indexed: 02/20/2024] Open
Abstract
Bifidobacterium species are essential members of a healthy human gut microbiota. Their presence in the gut is associated with numerous health outcomes such as protection against gastrointestinal tract infections, inflammation, and metabolic diseases. Regular intake of Bifidobacterium in foods is a sustainable way of maintaining the health benefits associated with its use as a probiotic. Owing to their global acceptance, fermented dairy products (particularly yogurt) are considered the ideal probiotic carrier foods. As envisioned in the definition of probiotics as "live organisms," the therapeutic functionalities of Bifidobacterium spp. depend on maintaining their viability in the foods up to the point of consumption. However, sustaining Bifidobacterium spp. viability during the manufacture and shelf-life of fermented dairy products remains challenging. Hence, this paper discusses the significance of viability as a prerequisite for Bifidobacterium spp. probiotic functionality. The paper focuses on the stress factors that influence Bifidobacterium spp. viability during the manufacture and shelf life of yogurt as an archetypical fermented dairy product that is widely accepted as a delivery vehicle for probiotics. It further expounds the Bifidobacterium spp. physiological and genetic stress response mechanisms as well as the methods for viability retention in yogurt, such as microencapsulation, use of oxygen scavenging lactic acid bacterial strains, and stress-protective agents. The report also explores the topic of viability determination as a critical factor in probiotic quality assurance, wherein, the limitations of culture-based enumeration methods, the challenges of species and strain resolution in the presence of lactic acid bacterial starter and probiotic species are discussed. Finally, new developments and potential applications of next-generation viability determination methods such as flow cytometry, propidium monoazide-quantitative polymerase chain reaction (PMA-qPCR), next-generation sequencing, and single-cell Raman spectroscopy (SCRS) methods are examined.

Abstract
Cheddar cheese-derived bioactive peptides are considered a potential component of functional foods. A positive impact of bioactive peptides on diet-related chronic, non-communicable diseases, like obesity, cardiovascular diseases, and diabetes, has been observed. Bioactive peptides possess multifunctional therapeutic potentials, including antimicrobial, immunomodulatory, antioxidant, enzyme inhibitory effects, anti-thrombotic, and phyto-pathological activities against various toxic compounds. Peptides can regulate human immune, gastrointestinal, hormonal, and neurological responses, which play an integral role in the deterrence and treatment of certain diseases like cancer, osteoporosis, hypertension, and other health disorders, as described in the present review. This review summarizes the categories of the Cheddar cheese-derived bioactive peptides, their general characteristics, physiological functions, and possible applications in healthcare.

Food Sci Nutr 2023; 11:2197-2210. [PMID: 37181300 PMCID: PMC10171538 DOI: 10.1002/fsn3.3095] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2022] [Revised: 09/20/2022] [Accepted: 09/26/2022] [Indexed: 11/06/2022] Open
Abstract
The present study aimed to optimize the formulation of buckwheat/lentil gluten-free beverages fermented with Lactobacillus plantarum and Bifidobacterium bifidum. Physicochemical parameters of 14 different beverages, such as pH, acidity, total solids, ash, total phenol content, antioxidant activity, and sensory test, were assessed after 24 h of fermentation. The results showed that the numbers of viable cells of lactobacilli and bifidobacteria on the first day of the experiment were 9.9 and 9.6 log (CFU ml-1), respectively, which were over 9 log (CFU ml-1). During 24 h from the fermentation, the number of viable cells for all beverages decreased, which reached an average probiotic count of 8.81 log (CFU ml-1) that was statistically significantly different from the probiotic count before fermentation (p < .05). Cell viability was evaluated and shelf life was estimated during 15-day refrigerated storage. At the end of the storage (15th day), the beverages contained an average of 8.4 log (CFU ml-1) of live lactobacilli cells and 7.8 log (CFU ml-1) of viable bifidobacterial cells. The optimized levels of independent factors for sprouted buckwheat and lentil flours were 51.96% and 48.04%, respectively. The optimized probiotic beverage was contained 0.25 (% lactic acid) acidity, 5.7 pH, 7.9% total solids, 0.4% ash, 41.02% DPPH, 26.96 (mg GAE/ml) phenol compounds, and 8.65 log (CFU ml-1) probiotic count. The optimized beverage had distinct organoleptic properties on day 15 of refrigerated storage. This study showed that Bifidobacterium bifidum can be used for the development of potentially probiotic beverage with sprouted buckwheat and lentil.

Abstract
Probiotic microorganisms that are potentially beneficial to the health of the host are commercially available in a great variety of products. Not all microorganism strains present in products have proven beneficial to the health properties. These products include not only foodstuffs but also dietary supplements, food for special medical purposes, medicinal products, as well as cosmetics and medical devices. These products contain from one to a dozen bacterial strains of the same or different species and sometimes also fungal strains. Since the pro-health effects of probiotics depend on a specific strain, the number of its cells in a dose, and the lack of pathogenic microorganisms, it is extremely important to control the quality of probiotics. Depending on the classification of a given product, its form, and its content of microorganisms, the correct determination of the number of microorganisms and their identification is crucial. This article describes the culture-dependent and culture-independent methods for testing the contents of probiotic microorganisms, in addition to biochemical and genetic methods of identification. The microbiological purity requirements for various product categories are also presented. Due to numerous reports on the low quality of probiotic products available on the market, it is important to standardise research methods for this group of products and to increase the frequency of inspections of these products.

Abstract
Since their discovery, bifidobacteria have been considered to represent cornerstone commensal microorganisms in the host-microbiome interface at the intestinal level. Bifidobacteria have therefore enjoyed increasing scientific and commercial interest as a source of microorganisms with probiotic potential. However, since functional and probiotic traits are strictly strain-dependent, there is a constant need to isolate, cultivate, and characterize novel strains, activities that require the utilization of appropriate media, as well as robust isolation, cultivation, and preservation techniques. Besides, effective isolation of bifidobacteria from natural environments might require different manipulation and cultivation media and conditions depending on the specific characteristics of the sample material, the presence of competitive microbiota, the metabolic state in which bifidobacteria might be encountered within the sample and the particular metabolic traits of the bifidobacterial species adapted to such inhabitation.A wide array of culture media recipes have been described in the literature to routinely isolate and grow bifidobacteria under laboratory conditions. However, there is not a single and universally applicable medium for effective isolation, recovery, and cultivation of bifidobacteria, as each growth medium has its own particular advantages and limitations. Besides, the vast majority of these media formulations was not specifically formulated for these microorganisms, and thus information on bifidobacterial cultivation options is scarce while being scattered throughout literature. This chapter intends to serve as a resource summarizing the options to cultivate bifidobacteria that have been described to date, highlighting the main advantages and limitations of each of them.
