Effect test
example 1
[0071] Cats were exposed to water containing 25 mM proline + 25 mM histidine with a composition containing 50 mM histidine. The method uses a two-bottle selection test with 24 cats (final number of cats may vary per test due to discarded data due to spillage, etc.). The cats were each in a separate house during the test periods and had free access to available water between test periods. The test consisted of a choice test between a tastant / mixture dissolved in deionized water at a given concentration and deionized water alone or another tastant / mixture. Position bias (eg A / B Exposure 1 and B / A Exposure 2) and evaporation losses are controlled. The testing time was 36 hours (ie, 18 hours per day, alternated every two days). After each test on two consecutive days, the cats were allowed to rest for two consecutive days. Cats were offered a dry diet as a single meal 1 hour after the start of the test period, calculated to meet the individual needs of each cat.

[0080] The difference test was performed as in example 1, however, the composition comprising 25 mM proline + 25 mM histidine was compared to the composition comprising 50 mM proline only.
[0081] The result is shown below and figure 2 middle.

[0088]
[0089] It can be seen that the intake of proline + histidine was on average 56.07 g higher than the intake of proline alone, ie animals clearly preferred the combination of proline and histidine over proline alone.
example 3
[0091] The difference test was performed as in Example 1, however, a composition comprising 25 mM threonine + 25 mM histidine was compared to a composition comprising 50 mM threonine only.

[0097]
[0098] It can be seen that the intake of threonine+histidine is 34.48g higher on average than the intake of threonine alone, that is, animals clearly prefer the combination of threonine and histidine compared to threonine alone.

Abstract
The present invention relates to the use of a first amino acid selected from the group consisting of glycine, alanine, cysteine, histidine, leucine, methionine, phenylalanine, serine, tryptophan and tyrosine or a mixture of two or more thereof; a second amino acid selected from the group consisting of aspartic acid, cystine, glutamic acid, glutamine, isoleucine, lysine, aspartic acid, ornithine, threonine, valine, proline and hydroxyproline or a mixture of two or more thereof and one or more furanones for increasing the palatability of a foodstuff to a companion animal. The invention also relates to a pet foodstuff or supplement comprising a first amino acid selected from the group consisting of glycine, alanine, cysteine, histidine, leucine, methionine, phenylalanine, serine, tryptophan and tyrosine or a mixture of two or more thereof; a second amino acid selected from the group consisting of aspartic acid, cystine, glutamic acid, glutamine, isoleucine, lysine, aspartic acid, ornithine, threonine, valine, proline and hydroxyproline or a mixture of two or more thereof and one or more furanones, and also to a method of increasing the palatability of a foodstuff to a companion animal.
Description
technical field [0001] The present invention relates to the use of a first amino acid, a second amino acid and one or more furanones for improving the palatability of food to companion animals, wherein the first amino acid is selected from the group consisting of glycine, alanine, cysteine acid, histidine, leucine, methionine, phenylalanine, serine, tryptophan and tyrosine or a mixture of two or more thereof, the second amino acid is selected from aspartic acid, cysteine amino acid, glutamic acid, glutamine, isoleucine, lysine, aspartic acid, ornithine, threonine, valine, proline and hydroxyproline or both a mixture of one or more species. The invention also relates to a pet food or supplement comprising a first amino acid, a second amino acid and one or more furanones, and to a method of improving the palatability of the food to companion animals, wherein the first amino acid is selected from the group consisting of glycine, alanine acid, cysteine, histidine, leucine, methi...
