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.
1. A method of preparing a probiotic food or beverage for human consumption, the method comprising:
providing a probiotic composition in a dry or powdered form;
heating (1) the probiotic composition or (2) at least one component of the probiotic composition if at least one component is separate from one or more other components, to a temperature in a range of 42° C. to 100° C.;
wherein the probiotic composition comprises the following components: one or more Bacillus species in spore form, one or more L-amino acids, one or more buffers, and any food or beverage product;
wherein the heating step comprises adding a hot liquid comprising water to the probiotic composition or the at least one component of the probiotic composition;
wherein the one or more buffers maintain the pH of the probiotic composition in a range of around 6-8 when the water is added to the probiotic composition; and
wherein all ingredients in the probiotic composition are GRAS (Generally Regarded as Safe) for human consumption under U.S. federal standards.
2. The method of claim 1 wherein the hot liquid consists essentially of water.
3. The method of claim 1 wherein the food or beverage product comprises any variety of tea and the probiotic composition is in a water permeable bag;
wherein the heating step comprises placing the water permeable bag in a container of the hot liquid; and
wherein the method further comprises:
producing a drinkable tea by steeping the probiotic composition in the hot water.
4. The method of claim 3 wherein the probiotic composition steeps in the hot water for 2 to 10 minutes prior to being consumed by a human.
5. The method of claim 1 wherein at least one of the components of the probiotic composition is separate from one or more other components of the probiotic composition, the method further comprising mixing all of the components to form the probiotic composition.
6. The method of claim 1 further comprising placing the probiotic composition or components of the probiotic composition in a water permeable bag;
wherein the heating step comprises placing the water permeable bag in a container of the hot liquid.
7. The method of claim 1 wherein the probiotic composition is heated for 2 to 10 minutes prior to being consumed by a human.
8. The method of claim 2 wherein the food or beverage product is any variety of tea, hot chocolate, coffee, soup, gravy, or sauce.
9. The method of 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.
10. The method of claim 9 wherein the probiotic composition further comprises at least one of the following: (1) D-glucose, (2) D-fructose, (3) an osmoprotectant or (4) a source of potassium ions.
11. The method of claim 9 wherein the probiotic 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.
12. The method of claim 9 wherein the probiotic composition further comprises potassium chloride.
13. The method of claim 1 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.
14. The method of claim 1 wherein the Bacillus species are Bacillus licheniformis , or Bacillus subtilis , or a combination thereof.
15. The method according to claim 14 wherein the Bacillus species are two different strains of Bacillus licheniformis and at least one strain of Bacillus subtilis.
16. The method according to claim 15 wherein the Bacillus species comprises around 40% of a first strain of Bacillus licheniformis , around 40% of a second strain of Bacillus licheniformis , and around 20% of the at least one strain of Bacillus subtilis.
17. The method according to claim 9 wherein the Bacillus species are two different strains of Bacillus licheniformis and at least one strain of Bacillus subtilis.
18. The method according to claim 1 wherein the probiotic composition further comprises a preservative or germination inhibitor.
19. The method according to claim 18 wherein the preservative or germination inhibitor comprises propylparaben, methylparaben, NaCl, D-alanine, or a combination thereof.
20. The method according to claim 18 wherein the composition is heated to a temperature in a range of 44° C. to 60° C.
21. The method of claim 1 wherein the food or beverage product wherein the food or beverage product is any variety of tea, hot chocolate, cereal, oatmeal, creamer, coffee, soup, gravy, or sauce and wherein the one or more buffers comprises a (1) phosphate buffer, (2) combination of a citrate and citric acid, (3) HEPES, (4) Tris base, or (5) a combination thereof.
22. The method of claim 1 wherein the food or beverage product is any variety of tea, hot chocolate, coffee, soup, gravy, or sauce and wherein the one or more buffers comprises (1) phosphate buffer, (2) combination of a citrate and citric acid, (3) HEPES, (4) Tris base, or (5) a combination thereof.
