Composition
The present invention relates to a composition and a method of preparing or treating food products so as to improve their aroma, flavor, mildness, sweetness, consistency, texture, body, mouth feel, firmness, viscosity, gel fracture, wheying off, structure and/or organoleptic properties, nutrition and/or health benefits. In particular, the present invention provides a composition comprising a live micro-organism, an enzyme produced by said micro-organism and an exopolysaccharide (EPS) produced by the activity of said enzyme.
1. A composition for consumption, said composition comprising an isolated viable lactic acid micro-organism, an enzyme synthesised by said micro-organism and an exopolysaccharide (EPS) product of said enzyme; wherein said micro-organism is Lactobacillus sakei strain 570, and wherein said enzyme is glycosyl transferase enzyme, fructosyl transferase enzyme or glucan sucrase enzyme capable of polymerising sucrose and/or lactose and/or stacchyose, and/or raffinose and/or verbascose.
2. A composition for consumption, said composition comprising an isolated viable lactic acid micro-organism, an enzyme synthesized by said micro-organism and an exopolysaccharide (EPS) product of said enzyme; wherein said micro-organism is Lactobacillus sakei strain 570 and wherein the EPS product is formed in situ by cultivating the lactic acid micro-organism with a suitable enzyme substrate, and wherein said enzyme is glycosyl transferase enzyme, fructosyl transferase enzyme or glucan sucrase enzyme capable of polymerising sucrose and/or lactose and/or stacchyose, and/or raffinose and/or verbascose.
3. A composition according to claim 1 or claim 2 wherein said EPS is a homo-EPS.
4. A composition according to claim 3 wherein said homo-EPS comprises an oligosaccharide component.
5. A composition according to claim 4 wherein said oligosaccharide component of the EPS comprises glucose.
6. A composition according to claim 1 or claim 2 wherein the polysaccharide or the oligosaccharide component of the EPS comprises fructan or glucan.
7. A composition according to claim 6 wherein the oligosaccharide is fructo-oligosaccharide or gluco-oligosaccharide.
8. A composition according to claim 1 or claim 2 wherein the amount of produced EPS is capable of being modulated.
9. A composition according to claim 8 wherein said amount of EPS is modulated by the number of viable lactic acid microorganisms, the length of the fermentation process, the incubation temperature, the pH or the acceptor molecule maltose.
10. A composition according to claim 1 or claim 2 wherein said EPS improves the texture, body, mouth feel, viscosity, structure and/or organoleptic properties of food product containing said EPS as an ingredient.
11. A composition according to claim 1 or claim 2 wherein the composition is used to ferment milk and produce a yoghurt like ingredient containing structure forming EPS and/or nutritional oligosaccharide.
12. A composition according to claim 1 or claim 2 wherein the composition acts as prebiotic when used as an ingredient to products for consumption or to pharmaceutical products.
13. A composition according to claim 1 or claim 2 wherein the components of the composition have the capacity to reduce the production of gas by the gastrointestinal microorganisms when used as ingredients to products for consumption or to pharmaceutical products.
14. A composition according to claim 1 or claim 2 wherein said composition is in a high concentrated form wherein the composition comprises a high concentration of the viable micro-organism and/or the enzyme synthesized by said micro-organism and/or the EPS produced by said enzyme.
15. A composition according to claim 1 or claim 2 wherein said composition is freeze dried, spray dried and/or resuspended.
16. A product for consumption obtained by a method comprising admixing a composition with another component so as to form said product for consumption; wherein said composition is a composition according to claim 1 or claim 2 .
17. A product according to claim 16 wherein the composition is added to a dairy product.
18. A product according to claim 16 wherein the composition is added to yoghurt milk before and/or after the fermentation of said milk.
19. The product according to claim 16 wherein the product is a functional food.
20. A pharmaceutical product produced by a method comprising admixing a composition with another component to produce said pharmaceutical product, wherein said composition is a composition according to claim 1 or claim 2 .
21. A container comprising a composition, wherein said composition is a composition according to claim 1 or claim 2 .
22. A container comprising a composition, wherein said composition is a composition according to claim 1 or claim 2 , and wherein said container has thereon a label indicating use and/or approval for use to improve the microbial balance of the gastrointestinal tract after consumption of said product.
23. A product according to 20 wherein the composition is added to a dairy product.
24. A product according to claim 17 wherein the composition is added to yoghurt milk.
25. A food product comprising as a food ingredient a composition according to claim 1 or claim 2 .
26. A pharmaceutical product comprising a composition according to claim 1 or claim 2 .
27. A composition according to claim 3 wherein said EPS comprises glucose.
