Health awareness has grown to a greater extent among consumers and they are looking for healthy probiotic counterparts. Keeping in this view, the present review focuses recent developments in dairy and non-dairy probiotic products. All over the world, dairy probiotics are being commercialized in many different forms. However, the allergy and lactose intolerance are the major set-backs to dairy probiotics. Whereas, flavor and refreshing nature are the major advantages of non-dairy drinks, especially fruit juices. Phenotypic and genotypic similarities between dairy and non-dairy probiotics along with the matrix dependency of cell viability and cell functionality are reviewed. The heterogeneous food matrices of non-dairy food carriers are the major constraints for the survival of the probiotics, while the probiotic strains from non-dairy sources are satisfactory. Technological and functional properties, besides the viability of the probiotics used in fermented products of non-dairy origin are extremely important to get a competitive advantage in the world market. The functional attributes of dairy and non-dairy probiotic products are further enhanced by adding prebiotics such as galacto-oligosaccharide, fructo-oligosaccharide and inulin.

The objective of this study was to find out the suitability of different fruit juices for probiotication by using Lactobacillus casei. Phyto-chemical analysis of different fruit juices (mango, sapota, grape and cantaloupe) were carried out using the standard methods. Carbohydrates, flavoniods, tannins, glycosides were present and alkaloids and saponins were absent in all the above fruit juices. Further analysis by TLC and DPPH methods indicated good antioxidant activity in all the fruit juices except for cantaloupe juice. Probiotication of fruit juices with L. casei, decreased pH and increased the titratable acidity within 72 h. Physico-chemical properties were also determined at different time intervals (24, 48 and 72 h) of probiotication. Based on the above results, it was inferred that the beverage prepared from the probiotication of fruit juices with L. casei could be useful in providing health benefits to the consumers.DOI: http://dx.doi.org/10.3126/ijasbt.v1i3.8301 Int J Appl Sci Biotechnol, Vol. 1(3) 2013 : 127-131
