Description
BACKGROUND OF THE INVENTION
Field of the Invention

The present invention in general relates to probiotics. More specifically, the present invention relates to beverage compositions comprising probiotic Bacillus coagulans strain MTCC 5856.


Description of Prior Art

Probiotics are gaining importance as a dietary supplement owing to their ability to modify the gut microflora yielding increased health benefits. These probiotics can survive the acidic environments of the stomach and small intestine, but are not observed to colonize the gastro-intestinal tract. Thus, there exists a need for constantly supplementing probiotics for the therapeutic benefits to persist.


Beverages are widely consumed food constituents and can be looked upon as a source for co-administering probiotics. It must be noted that beverage compositions are subjected to treatments under extreme stress, temperature and pressure conditions like brewing or aeration wherein the viability of the probiotic spores should be maintained post treatment to result in a successful administration.


United States Patent Application 20090232941 discloses a beverage composition comprising Bacillus coagulans strains GBI-30, GBI-20 and GBI-40. United States Patent Application 20130295226 discloses a fruit beverage composition comprising Lactobacillus paracasei. Both these applications do not disclose the method of brewing and the survival of the probiotic bacteria in harsh conditions. Also, it is well known in the scientific art that that biological effects of probiotics or products thereof are strain specific and cannot be generalised among genera, species and strains (Probiotics: In Depth/NCCIH, U.S. Department of Health and Human Services, National Institutes of Health). Hence, there still exists a need to find a probiotic strain that is more efficient and viable when subjected to extreme stress, temperature and pressure conditions.


The present invention solves the above technical problem by disclosing a probiotic strain that is viable and efficient when co-administered with beverages.


The principle objective of the inventions is to disclose beverage compositions comprising Bacillus coagulans MTCC 5856 wherein the spore viability is maintained post treatments.


The present invention fulfils aforesaid objectives and provides further related advantages.


SUMMARY OF THE INVENTION

The present invention discloses beverage compositions that have been subjected to treatments under extreme stress, temperature and pressure conditions like brewing or aeration and comprise Bacillus coagulans MTCC 5856 spores and water soluble prebiotic fibers wherein the spore viability is maintained post said treatments.

Effect of Gastric Stress and Brewing Conditions on the Germination of Bacillus Coaglans MTCC 5856 Spores


The effect of gastric stress on the Bacillus coagulans MTCC 5856 spores was studied by treating brewed coffee or tea (as described in above paragraph) in acidic conditions. The pH of brewed coffee or tea was adjusted aseptically to 1.5 using 2 N HCl and incubated at 37° C. for 3 h with low r.p.m. After 3 h of incubation, again pH was adjusted aseptically back to 7.0 using 2 N NaOH and 0.5% (w/v) ox bile was added to tea or coffee flask. Oxygen reducing enzyme Oxyrase (Oxyrasei for Broth, Oxyrase, Inc. Mansfield, Ohio. USA) was also added to each flask. Further flasks were incubated at 37° C. for 24 h with low r.p.m. pH values at 0 h of incubation and after 24 h of incubation were also recorded. Optical density (OD) at 600 nm was recorded at 0 h and after 24 of incubation by diluting the sample into sterilized demineralized water to 1:5.


Example 2: Results for Brewing Coffee and Tea with Bacillus coagulans MTCC 5856 Brewed Coffee with Bacillus coagulans MTCC 5856

The thermo-stability and compatibility of Bacillus coagulans MTCC 5856 spores in coffee was evaluated during brewing using electric brewer. Stainless steel and paper filter were used in brewer to understand the feasibility of probiotic brewing. There was 0.5 Log10 cfu (spores) reduction after brewing which remained almost same even after 10 min of incubation at room temperature (Table 3). The data suggested that Bacillus coagulans MTCC 5856 spores remained 94.83% viable after brewing using Stainless steel filter. There was no significant difference observed when coffee was brewed using stainless steel or paper filters.

Germination of Spores


To deliver the right amount of viable Bacillus coagulans MTCC 5856 spores in the human gut, the effect of brewing conditions and gastric stress on the germination of Bacillus coagulans MTCC 5856 spores was conducted. Tea and coffee along with the Bacillus coagulans MTCC 5856 spores were brewed and then subjected to gastric stress (acid and bile) followed by anaerobic incubation at 37° C. with bile salts to mimic human conditions. This set of experiment was conducted to understand the spore germination when Bacillus coagulans MTCC 5856 is brewed and digested by human. Additionally, along with tea and coffee B. coagulans MTCC 5856 was brewed with water soluble prebiotic fibres (fructooligosaccharide, galacto-oligosacharides, inulin and polydextrose). Results of the experiment revealed that B. coagulans MTCC 5856 spores could germinate after brewing and surviving in harsh condition of gastric stress by using tea or coffee as sole nutritional source (Table 6). Additionally, there was further increase in the germination by the addition of water soluble prebiotic fibres (Table 6). This suggested that soluble prebiotic fibres have synergistic effect along with tea and coffee on the germination of B. coagulans MTCC 5856 spores.
