Probiotic products are dietary supplements containing live microorganisms producing beneficial health effects on the host by improving intestinal balance and nutrient absorption. Among probiotic microorganisms, those classified as lactic acid bacteria are of major importance to the food and feed industries. Probiotic cells can be produced using alternative carbon and nitrogen sources, such as agroindustrial residues, at the same time contributing to reduce process costs. On the other hand, the survival of probiotic cells in formulated food products, as well as in the host gut, is an essential nutritional aspect concerning health benefits. Therefore, several cell microencapsulation techniques have been investigated as a way to improve cell viability and survival under adverse environmental conditions, such as the gastrointestinal milieu of hosts. In this review, different aspects of probiotic cells and technologies of their related products are discussed, including formulation of culture media, and aspects of cell microencapsulation techniques required to improve their survival in the host.
益生菌产品是含有活微生物的膳食补充剂，这些微生物通过改善肠道平衡和营养吸收对宿主产生有益的健康影响。在益生菌微生物中，那些被归类为乳酸菌的对食品和饲料工业至关重要。益生菌细胞可以使用替代碳源和氮源（如农工业残渣）来生产，同时有助于降低生产成本。另一方面，益生菌细胞在配方食品以及宿主肠道中的存活是关乎健康益处的一个重要营养方面。因此，人们研究了几种细胞微囊化技术，作为在不利环境条件（如宿主的胃肠道环境）下提高细胞活力和存活率的一种方法。在这篇综述中，讨论了益生菌细胞及其相关产品技术的不同方面，包括培养基的配方，以及提高其在宿主中存活所需的细胞微囊化技术方面。
