Approach of probiotics in mental health as a psychobiotics.

Probiotics are those beneficial microbes that confer various health benefits to humans when integrated in diet in adequate amount. They possess vital metabolites having nutritional and therapeutic properties which provide countless health benefits. Scientific discoveries demonstrated that these living microbial consortiums may exert impact on anxiety, depression, cognitive functions, stress responses and behaviours. Those probiotics that controls the functioning or actions of central nervous system (CNS) conciliated by the gut brain axis (GBA) through neural, humoral and metabolic pathways to ameliorate the gastrointestinal activity as well as anti-depressant and anxiolytic capacity are known as psychobiotics. Few evidences have confirmed the remedial effects of psychobiotics against neurological conditions or disorders. So, therapeutic approach of psychobiotics leads to the future possibilities in the development field for researchers. This review article describes the potential role and mechanism of action of psychobiotics.

Evaluation of improved functional characteristics of Lactobacillus enriched fruit bar prepared from stone fruits of Mid Himalayan belt.

Probiotic enriched functional fruit bar was prepared by using stone fruits (i.e. apricot and plum) of Mid Himalayan belt. Purpose of this study is to determine the survival of potential probiotic isolates in fruit bar and to study physico-chemical and sensorial properties of the product along with nutritional profile as well as microbial safety. Probiotics bacteria Lactobacillus rhamnosus KC6 and Lactobacillus paraplantarum Sam 1 were used to prepare fruit bar. Probiotic fruit bar was prepared in seven sets and was evaluated for various physico-chemical, nutritional and functional properties during storage period. It was revealed in the study that probiotic fruit bar is nutritionally and functionally better than non-probiotic fruit bar. Probiotic encapsulated bacteria in co-culture combinations efficiently enhanced nutritional quality of fruit bar. Microbiological evaluation of the product revealed that the viability of encapsulated probiotic co-culture bacteria was significantly greater as compared to free cells in the probiotic fruit bar.
