| abstract |
The present invention describes compositions comprising an artificial sweetener and a yeast extract, said yeast extract comprising free amino acids and one or more 5'-ribonucleotide(s), wherein the total amount of said one or more 5'-ribonucleotide(s) is at least 10% w/w, wherein said one or more 5'-ribonucleotide(s) comprises 5'-GMP and optionally 5'-IMP and wherein the ratio between the percentage (w/w) of free amino acids and the percentage (w/w) of the total amount of 5'-GMP and 5'-IMP in the yeast extract is lower than 3.5, all weights in the yeast extract being based on NaCl free yeast extract dry matter. Preferably said yeast extract comprises an amount in free amino acids lower than 40% based on NaCl free yeast extract dry matter and/or has a degree of protein hydrolysis lower than 50%. Preferably, the weight ratio between artificial sweetener and yeast extract in the compositions based on NaCl free yeast extract dry matter is lower than 15, preferably comprised between 0.001 and 6. When these compositions are used to sweeten foodstuff, they do not confer any aftertaste or any taste intrinsic to the yeast extract to the food. Foodstuff comprising said compositions, the use of said compositions and of the yeast extract to sweeten foodstuff are also described. |
