Research studies carried out in the 20^th century made it possible to isolate micro-organisms, the socalled probiotics, which, if consumed with food, have a particularly positive effect on consumer health. The objective of this study was to explain the reasonableness of adding probiotics to plant products, to describe the selected technological aspects of producing plant foods containing those micro-organisms, and to characterize raw products that can become their carrier. Among the factors in favour for using probiotics in plant foods, the impact thereof on high nutritive and sensory value is named as is a long tradition of fermenting them. It is possible to achieve both their growth and / or survival while foods are processed and stored, and, at the same time, to perpetuate their beneficial effect on health, among other things, by: selecting a suitable probiotics carrier, applying various methods to enhance the viability of probiotics, and micro-encapsulating them. A particularly important aspect of the technology is to ensure appropriate sensory properties of a product. Processed products of soybean, cereals, fruits, and vegetables are considered to be potential carriers of probiotics.
