Definitions
- the present invention relates to compositions for preparing a beverage.
- the compositions comprise a microorganism and/or an enzyme capable of hydrolysing chlorogenic acids of a coffee extract to phenolic acids. Beverages prepared with the compositions of the invention have improved antioxidant and/or anti-inflammatory properties. 0

- detoxifying enzymes e.g. glutathione- S-5 transferases GST
- the coffee-specific diterpenes cafestol and kahweol protect against aflatoxin Bl -induced genotoxicity trough a dual mechanism. Carcinogenesis 19, 1369-1375; Cavin, C. et al, 2003.

- This kind of antioxidant activity is known to protect against "oxidative stress” by reducing damaging free radicals that may be implicated e.g. in cancer, heart disease,0 degenerative brain disorders and ageing.
- the inventors have surprisingly found that treating coffee extract with microorganisms or enzymes capable of hydrolysing chlorogenic acids to generate phenolic acids results in improved antioxidant and/or anti-inflammatory properties of the coffee extract. Furthermore, it has been found that this treatment can take place in vivo when a human or an animal ingests a coffee extract in combination with an enzyme or microorganism capable of hydrolysing chlorogenic acids to generate phenolic acids.

- TIM Gastric small-intestinal model
- the gastric small-intestinal model, TIM-I comprises four connected compartments that represent the stomach, duodenum, jejunum and ileum, respectively.
- Each compartment consists of a glass outer wall with a flexible inner wall.
- the flexible wall is surrounded by water at 37°C to squeeze the walls, which ensures mixing of the food with the secreted enzymes by peristaltic movements in the gastro -intestinal tract.
- the experiments in the model were performed under average physiological conditions of the gastro -intestinal tract. During the experiments, the temperature was kept at 37°C and salivary, gastric, biliary, and pancreatic secretions were simulated. The digestion process in the model was monitored for 6 h. During the first 3.5 h, the gastric content was gradually delivered into the small intestine "pyloric valve". At the end of the experiment, approximately 80 % of the small-intestine content was gradually delivered into the "large intestine" via the ileocaecal valve.

- 310 ml acetate buffer (20 mM, pH 6.5) After addition of 10 ml start residue (5 g of pepsin and 5 g of lipase enzyme solutions) the solution was injected into the gastric compartment of TIM. During digestion, total dialysate was collected for 0-2, 2-4, and 4-6 h. After 6 h experiment, the residues from the compartments of the stomach, duodenum, jejunum and ileum were analysed to calculate the mass balance of chlorogenic acids.
- the samples were passed through a 0.45 ⁇ m pore size syringe filters (Millipore SLHA 025 BS) and analysed by HPLC as described in Example 1.
- Lactobacillus johnsonii (CNCM 1-1225)
- 310 ml of acetate buffer solution (20 mM, pH 6.5) containing a total of 3.3 E9 cfu of spray-dried preparation of L. johnsonii were put into the gastric compartment after addition of 10 ml start residue.
- 10 ml of acetate buffer containing 4.5 g Nescafe Protect was then injected by a syringe into the gastric compartment 15 min after starting digestion simulation.
