    [0043] The preferred compounds are shown again in the following Figure:

    ##STR00001##

    [0044] In principle, the therapeutic preparations may comprise both the substances which form component (a) and (b), in each case in amounts of approximately 0.1 mg/kg (corresponding to 0.1 ppm) to approximately 1% by weight. However, the substances are preferably present in each case in amounts of approximately 0.5 to approximately 1000 mg/kg (corresponding to approximately 0.5 to approximately 1000 ppm), preferably of approximately 1 to approximately 500 mg/kg, more preferably of approximately 3 to approximately 300 mg/kg, particularly preferably of approximately 5 to approximately 200 mg/kg and most preferably of approximately 10 to 100 mg/kg.

    [0045] The preparations according to the invention may comprise the substances which form components (a) and (b) in the weight ratio of approximately 1:100 to approximately 1:1, preferably 1:90 to approximately 1:2 and particularly of approximately 1:5 to approximately 1:10.

    [0046] Oral Preparations

    [0047] The present invention further relates to a preparation for oral administration, specifically providing nutrition or enjoyment, comprising as already elucidated in detail above [0048] (a) bitter-masking acting substances and [0049] (b) substances which induce the secretion of gastric acid.

    [0050] The preparations providing nutrition or enjoyment (i.e. suitable for consumption) are, in the context of this invention, e.g. bakery products (e.g. bread, dry biscuits, cakes, other baked goods), confectionery (e.g. chocolates, chocolate bar products, other bar products, fruit gums, hard and soft caramels, chewing gum), alcoholic or non-alcoholic drinks (e.g. coffee, tea, wine, wine-based drinks, beer, beverages containing beer, liqueurs, spirits, brandies, fruit-containing carbonated beverages, isotonic drinks, soft drinks, nectars, fruit and vegetable juices, fruit or vegetable juice preparations), instant drinks (e.g. instant cocoa drinks, instant tea drinks, instant coffee drinks), meat products (e.g. ham, fresh or cured sausage, spiced or marinated fresh or cured meat), eggs or egg products (dried egg, egg white, egg yolk), cereal products (e.g. breakfast cereals, muesli bars, precooked instant rice products), dairy products (e.g. milk drinks, ice milk, yogurt, kefir, cream cheese, soft cheese, hard cheese, dried milk powder, whey, butter, buttermilk, partially or fully hydrolyzed milk protein-containing products), products made from soy protein or other soybean fractions (e.g. soy milk and products manufactured therefrom, preparations containing soy lecithin, fermented products such as tofu or tempeh or products manufactured therefrom, soy sauce), fruit preparations (e.g. jams, fruit ice cream, fruit sauces, fruit fillings), vegetable preparations (e.g. ketchup, sauces, dried vegetables, frozen vegetables, precooked vegetables, pickled vegetables, cooked vegetables), snack foods (e.g. baked or fried potato chips or reconstituted potato products, bread dough products, extrudates based on maize or peanut), products based on fat and oil or emulsions of the same (e.g. mayonnaise, remoulade, dressings, seasoning preparations), other ready meals and soups (e.g. dried soups, instant soups, precooked soups), spices, spice mixtures and especially seasonings which are used in the snack food sector.

    [0051] The oral preparations in the context of the invention may also serve as semi-finished goods for the preparation of further orally consumable preparations. The preparations in the context of the invention may also be in the form of capsules, tablets (oral and/or gastric disintegrating tablets), sugar-coated pills, granules, pellets, mixtures of solids, dispersions in liquid phases, as emulsions, as powders, as solutions, as pastes or as other swallowable or chewable preparations as food supplements.

    [0052] Preference is given here to incorporating one or more of the substances of group (a) in an orally consumable preparation, particularly in the form of preparations which can be swallowed (e.g. drinks, dispersions, emulsions, pastes, capsules which can dissolve in the mouth or stomach, tablets, compressed products, soft caramels, sugar-coated pills, granules, pellets, fruit gums) or in preparations not intended to be swallowed (e.g. chewing gum, hard caramels) releasing sufficient concentrations of substances of group (a) in an effective concentration.

    [0053] The substances of group (a) to be used in accordance with the invention in preparations suitable for consumption in accordance with the invention, particularly in the preferred concentrations to be used in accordance with the invention, have no appreciable taste of their own and in particular they have no unpleasant or objectionable flavors at the (preferred or particularly preferred) concentrations employed. The substances of group (a) are each capable alone and/or in mixtures to reduce or to completely block the bitterness of one or more of the substances of group (b).

    [0054] The substance(s) of group (a) and also preparations according to the invention comprising the substance(s) of group (a), can be fed orally in time sequence before, during or after oral administration of the substance(s) of group (b) or preparations comprising the substance(s) of group (b).

    [0055] Particularly advantageous here is the known fact that the substances of group (a) are regularly capable of partially or completely reducing the bitter (unpleasant) taste of the substances of group (b) and therefore can significantly increase the acceptability of the preparations. This is particularly the case if the substances of group (b) are applied at the same time as the substances of group (a).

    [0056] In the case of subsequent oral administration of the substance(s) of group (a), preparation forms are preferred which comprise the substance(s) of group (a) in a form which causes delayed release.

    [0057] In an alternative to the simultaneous oral administration, preparations may also be suitable which have one or more of the unpleasant tasting and gastric acid-stimulating substances of group (b) in an effective amount with respect to gastric acid stimulation and simultaneously comprise one or more of the substances of group (a) in an effective amount with respective to gastric acid stimulation.

    [0058] In principle, the oral preparations may comprise—be they finished or semi-finished products—both the substances which form component (a) and (b), in each case in amounts of approximately 0.1 mg/kg (corresponding to 0.1 ppm) to approximately 1% by weight. However, the substances are preferably present in each case in amounts of approximately 0.5 to approximately 1000 mg/kg (corresponding to approximately 0.5 to approximately 1000 ppm), preferably of approximately 1 to approximately 500 mg/kg, more preferably of approximately 3 to approximately 300 mg/kg, particularly preferably of approximately 5 to approximately 200 mg/kg and most preferably of approximately 10 to 100 mg/kg.

    [0059] The preparations according to the invention may comprise the substances which form components (a) and (b) in the weight ratio of approximately 1:100 to approximately 1:1, preferably 1:90 to approximately 1:2 and particularly of approximately 1:5 to approximately 1:10.

    INDUSTRIAL APPLICABILITY

    [0060] A preferred method for determining the desired effect of substances of group (a) on decreasing the effect of substances of group (b) consists of measuring the intracellular pH of HGT-1 cell cultures (human gastric tumor cell line) after treatment with the test substances as described in Liszt, K. I.; Walker, J.; Somoza, V. J. Agric Food Chem. 2012, 60, (28), 7022-7030. To date, only the somatostatin receptor (SSTR2) on the cell surface of gastric acid-secreting cells has been described as a target for reducing the secretion; this receptor has also been described in HGT-1 To date, these cells have only ever been brought into contact with potential SSTR2 regulators; the co-administration of bitter agonists and potential antagonists has not been described to date.

    [0061] Two further aspects of the present invention relate firstly to a non-therapeutic method for reducing and/or inhibiting secretion of gastric acid induced by food constituents, in which an effective amount of a bitter-masking acting substance is orally administered to a human or animal, and secondly the use of bitter-masking acting substances for reducing and/or inhibiting the secretion of gastric acid induced by food constituents. With regard to the nature of the substances and the amounts used thereof, reference is made to the embodiments above which are fully incorporated here.

    EXAMPLES

    [0062] Cell model

    [0063] Human parietal cells, also known as human gastric tumor cell line (HGT-1), are used as cell model. These were provided by Dr. C. Laboisse (Laboratory of Pathological Anatomy, Nantes, France). The cells were cultured under standard conditions at 37° C., 5% CO.sub.2 in DMEM (Dulbecco's Modified Eagle's Medium) with 4 g/l glucose, 10% FBS, 2% L-glutamine and 1% penicillin/streptomycin. For the measurement of the intracellular proton concentration, the cells are treated with trypsin/EDTA, the viability determined by means of trypan blue staining and 100 000 cells/well seeded in black 96-well plates.

    Example 1

    [0064] Determination of the intracellular pH of HGT-1 cell cultures in the presence of the substances of group (a) and substances of group (b)

    [0065] To measure the intracellular pH, the dye 1,5 -carboxyseminaphthorhodafluoro acetoxymethyl ester (SNARF-1-AM) is used. The cells in the 96-well plates are washed once with Krebs-Hepes buffer (KRHP) and incubated at 37° C. and 5% CO.sub.2 for 30 min with the dye dissolved in KRHP at a concentration of 3 μM. The cells are then washed twice with KRHP and substances of group (b), for example 3 mM caffeine or 0.3 mM theobromine, alone or in combination with substances of group (a), for example, homoeriodictyol (HED) or eriodictyol or matairesinol, lariciresinol or enterolactone, are applied in volumes of 100 μl at various concentrations in phenol red-free DMEM; as additional control experiments, the abovementioned substances of group (a) are tested alone. Homoeriodictyol is dissolved in double-distilled water while eriodictyol, matairesinol, lariciresinol or enterolactone are dissolved in ethanol (EtOH). The final concentration of solvent which is added to the cells is at most 1%. The fluorescent dye is excited at a wavelength of 488 nm and the emission measured at 580 nm and 640 nm. The ratio of the fluorescence values at 580 nm to 640 nm is compared to a calibration curve from which the pH can be determined. For the calibration curve, the cells are treated with a potassium phosphate buffer of different pH values from pH 7.2-8.2 and 2 μM nigericin. Nigericin equilibrates the intracellular and extracellular pH such that the intracellular pH may be defined. The intracellular H.sup.+ concentration is determined from the intracellular pH. The intracellular proton index (IPX) is calculated by log 2 transformation of the ratio of treated cells and untreated cells (control). The results given here are stated as percentage changes compared to untreated control cells (cf. Malte Rubach, R. L., Elisabeth Seebach, Mark M. Somoza, Thomas Hofmann; Somoza, a. V., Mol Nutr Food Res. in press, 2011; Rubach, M.; Lang, R.; Hofmann, T.; Somoza, V., Ann N Y Acad Sci 2008, 1126, 310-4; Rubach, M.; Lang, R.; Skupin, C.; Hofmann, T.; Somoza, V., J Agric Food Chem 2010, 58, 4153-61; Weiss, C.; Rubach, M.; Lang, R.; Seebach, E.; Blumberg, S.; Frank, O.; Hofmann, T.; Somoza, V., J Agric Food Chem 2010, 58, 1976-85; Liszt, K.

    [0084] As follows from Tables 1A and 1B, the proton secretion in the HGT-1 cells is stimulated by substances of group (b), in this case caffeine or theobromine, which effectively triggers acid secretion into the extracellular space. The substances of group (a) alone lead either to no significant effect (Tables 2A, 2B and 2D) or even to a significant decrease of the constitutive acid secretion (Table 2C). The stimulation of proton secretion by 3 mM caffeine (Tables 3A-3E) or 0.3 mM theobromine (Tables 3F-3I) could be reduced or completely inhibited by additional administration of the substances of group (a), particularly homoeriodictyol, eriodictyol, matairesinol, lariciresinol or enterolactone at a concentration of 0.3 mM.
