Abstract

This study explores the potential probiotic properties of yeasts isolated from various Chilean honeys, focusing on Ulmo, Quillay, and Mountain honeys. Six yeast strains were identified, including , sp., , , , and . Phenotypic characterization involved assessing their fermentative performance, ethanol and hops resistance, and cross-resistance. Ethanol concentration emerged as a limiting factor in their fermentative performance. The probiotic potential of these yeasts was evaluated based on resistance to high temperatures, low pH, auto-aggregation capacity, survival in simulated digestion (INFOGEST method), and antimicrobial activity against pathogens like , , and . Three yeasts, , , and , exhibited potential probiotic characteristics by maintaining cell concentrations exceeding 10 CFU/mL after digestion. They demonstrated fermentative abilities and resistance to ethanol and hops, suggesting their potential as starter cultures in beer production. Despite revealing promising probiotic and technological aspects, further research is necessary to ascertain their viability in producing fermented foods. This study underscores the innovative potential of honey as a source for new probiotic microorganisms and highlights the need for comprehensive investigations into their practical applications in the food industry.

摘要

本研究探索了从智利各种蜂蜜中分离出的酵母的潜在益生菌特性,重点关注乌木蜂蜜、皂树蜂蜜和山地蜂蜜。鉴定出了六种酵母菌株,包括 、 种、 、 、 和 。表型特征包括评估它们的发酵性能、对乙醇和啤酒花的耐受性以及交叉耐受性。乙醇浓度成为其发酵性能的限制因素。基于对高温的耐受性、低pH值、自聚集能力、在模拟消化(INFOGEST方法)中的存活率以及对 、 和 等病原体的抗菌活性,评估了这些酵母的益生菌潜力。三种酵母, 、 和 ,在消化后通过保持细胞浓度超过10 CFU/mL表现出潜在的益生菌特性。它们展现出发酵能力以及对乙醇和啤酒花的耐受性,表明它们有潜力作为啤酒生产中的发酵剂。尽管揭示了有前景的益生菌和技术方面,但仍需要进一步研究以确定它们在生产发酵食品中的可行性。本研究强调了蜂蜜作为新的益生菌微生物来源的创新潜力,并突出了对其在食品工业中的实际应用进行全面研究的必要性。
