Composition and method for germinative compounds in probiotic food and beverage products for human consumption
A composition and method for activating probiotic spores in food and beverage products, such as steeped teas, coffee, soups, and sauces. A nutrient-germinant composition comprises one or more L-amino acids, optionally one or more buffers to maintain the pH of the composition when added to water in a range of around 6-8, optionally D-glucose, D-fructose, or both D-glucose and D-fructose, and optionally, an osmoprotectant. The nutrient-germinant composition, one or more species of Bacillus spores, and a food or beverage product may be pre-mixed in any combination. Water is added to the mixture and heated to a temperature range of 42 to 100° C. to germinate the probiotic spores prior to being consumed.

a liquid composition comprising water;
wherein the probiotic composition is heated to a temperature in a range of 42° C. to 100° C.; and
wherein the one or more buffers maintain a pH of the composition in a range of around 6-8.
2. The probiotic food or beverage composition according to claim 1 wherein the one or more the L-amino acids is L-alanine, L-asparagine, L-valine, L-cysteine, a hydrolysate of soy protein, or a combination thereof.

4. The probiotic food or beverage composition according to claim 1 wherein the dry or powdered composition further comprises at least two of the following: (1) D-glucose, (2) D-fructose, (3) an osmoprotectant and (4) a source of potassium ions.
5. The probiotic food or beverage composition according to claim 2 wherein the dry or powdered composition further comprises potassium chloride.
6. The probiotic food or beverage composition according to claim 2 wherein the Bacillus species are one or more of Bacillus licheniformis, Bacillus subtillis, Bacillus amyloliquiefaciens, Bacillus polymyxa, Bacillus thuringiensis, Bacillus megaterium, Bacillus coagulans, Bacillus lentus, Bacillus clausii, Bacillus circulans, Bacillus firmus, Bacillus lactis, Bacillus laterosporus, Bacillus laevolacticus, Bacillus pumilus, Bacillus simplex, Bacillus sphaericus, Bacillus sonorensis, Bacillus, horneckiae, Bacillus axarquiensis, Bacillus mucilaginosus, Bacillus olivae.
7. The probiotic food or beverage composition according to claim 2 wherein the Bacillus species comprise Bacillus licheniformis , or Bacillus subtilis , or a combination thereof.
8. The probiotic food or beverage composition according to claim 7 wherein the Bacillus species comprise two different strains of the Bacillus licheniformis and at least one strain of the Bacillus subtilis.
9. The probiotic food or beverage composition according to claim 8 wherein the Bacillus species comprises around 40% of a first strain of the Bacillus licheniformis , around 40% of a second strain of the Bacillus licheniformis , and around 20% of the at least one strain of the Bacillus subtilis.
10. The probiotic food or beverage composition according to claim 2 wherein the dry or powdered composition further comprises a source of potassium ions.
11. The probiotic food or beverage composition according to claim 1 wherein the dry or powdered composition further comprises an osmoprotectant.
12. The probiotic food or beverage composition according to claim 11 wherein the food or beverage product is the soup.
13. The probiotic food or beverage composition according to claim 11 wherein the food or beverage product is the gravy or the sauce.
14. The probiotic food or beverage composition according to claim 1 wherein the composition is heated to a temperature in a range of 44° C. to 60° C.
15. The probiotic food or beverage composition according to claim 1 wherein all ingredients in the probiotic composition are GRAS (Generally Regarded as Safe) for human consumption under U.S. federal standards.
16. The probiotic food or beverage composition according to claim 1 wherein the liquid composition consists essentially of water.
17. A method of preparing a probiotic food or beverage composition for human consumption according to claim 1 , the method comprising:
contacting the dry or powdered composition with the liquid composition to form a mixed composition; and
heating (1) the mixed composition or (2) the liquid composition prior to the contacting step to a temperature in a range of 42° C. to 100° C.
18. The method according to claim 17 wherein the contacting step comprises adding the dry or powdered composition and the liquid composition to a container and mixing them together.
19. The method according to claim 17 wherein the one or more the L-amino acids is L-alanine, L-asparagine, L-valine, L-cysteine, a hydrolysate of soy protein, or a combination thereof; and
wherein the Bacillus species comprise Bacillus licheniformis , or Bacillus subtilis , or a combination thereof.
20. The method according to claim 17 wherein the food or beverage product comprises any variety of tea and the dry or powdered composition is in a water permeable bag; and
wherein the contacting step comprises placing the water permeable bag in a container of the liquid composition;
wherein the method further comprises steeping the water permeable bag in the liquid composition after or during the heating step for 2 to 10 minutes.
