This application claims the benefit of Korean Patent Application No. 10-2016-0175262, filed on Dec. 21, 2016, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein in its entirety by reference.
The present application relates to an amino acid beverage containing allulose.
Amino acids are a major constituent of human body proteins and are involved in various enzymatic reactions and biological reactions in the body. There are typically 20 amino acids in nature, and among them, 8 amino acids [isoleucine, leucine, lysine, tryptophan, valine, methionine, phenylalanine, and threonine] are referred to as essential amino acids, because they are not synthesized in our body. Since these essential amino acids must be obtained in vitro, they must be consumed through various amino acid sources such as amino acid supplements and amino acid drinks, and the market is expanding year by year.
However, amino acids are substances that can exhibit various negative organoleptic characteristics. Especially, when applied in beverages, they may be dissolved therein and develop an off-taste, an off-odor, and the like, more strongly.
In order to solve such problems, there have been reported a method for masking an off-taste and an off-odor of amino acids with citrus oils (JP 2007-116939 A), a method for reducing a bitter taste of amino acids with ornithine (WO 2004-052125 A1), or the like. However, the effect of improving organoleptic properties of an amino acid beverage using allulose has not been reported.
Under these circumstances, the present inventors have conducted extensive studies and made extensive efforts to reduce the negative organoleptic characteristics of a beverage containing amino acids and have found that when allulose is used, the off-taste, the off-odor, and an acrid taste of the amino acid beverage are reduced and the overall preference for the amino acid beverage is remarkably increased, thereby completing the present application.
An aspect of the present application provides a beverage comprising water, an amino acid, and allulose.
Another aspect of the present application provides a method for reducing an off-taste, an off-odor, or an acrid taste of a beverage containing an amino acid, comprising a step of mixing water, the amino acid, and allulose.
Hereinafter, the present application will be described in more detail.
Meanwhile, the respective explanations and embodiments disclosed in the present application can also be applied to other explanations and embodiments. That is, all combinations of various elements disclosed in this application fall within the scope of the present application.

The amino acid beverage of the present application includes allulose, thereby reducing the off-taste, the off-odor, and the acrid taste resulting from the amino acid, and remarkably enhancing preferences of consumers. In addition, since the contained allulose has almost no calories, the amino acid beverage of the present application meets the essential health directionality of amino acid beverages.
Hereinafter, the present application will be described in more detail through Examples. However, these Examples are for illustrative purposes only, and the scope of the present application is not limited thereto. This will be apparently understood by those skilled in the art to which this application belongs.
Throughout the specification of the present application, “%” used to denote the concentration of a specific substance refers to solid/solid (weight/weight) %, solid/liquid (weight/volume) %, and liquid/liquid (volume/volume) %, unless otherwise stated.
Amino acid beverages were prepared according to the following procedure by mixing raw materials in the ratios shown in Tables 1 to 3.
First, saccharides, L-amino acids (CJ CheilJedang), the grapefruit concentrate (65 Brix, JC World), Rebaudioside-A (Ra90, Macrocare), citric acid, trisodium citrate, refined salt, the stabilizer (T Texture 001, Cargill Sunkyung) and Cloudy (Bolak) were weighed and placed into a beaker, followed by mixing with purified water to a total amount ratio of 100 weight %. In Comparative examples 1 to 4, sucrose (white sugar, CJ CheilJedang) was used as the saccharides, and in Experimental examples 1 to 20, allulose (liquid allulose, 71 Brix, 95% or more of allulose based on dry solids) was used as the saccharides and the contents thereof were 3, 5, 10, 15, and 18 weight % [based on dry solids, 2.02, 3.37, 6.75, 10.12, and 12.14 weight %]. As L-amino acids, Experimental examples 1, 5, 9, 13 and 17 used L-arginine; Experimental examples 2, 6, 10, 14, and 18 used L-methionine; Experimental examples 3, 7, 11, 15, and 19 used L-ornithine; and Experimental examples 4, 8, 12, 16, and 20 used L-citrulline. Thereafter, the mixture was homogenized by mixing on a magnetic stirrer for 20 minutes, and the grapefruit flavor (Samjung Flavor) was put in accordance with a mixing ratio into the obtained homogenized mixture. A glass container was filled with the mixture, sealed with a cap, sterilized at 95° C. in a constant temperature water bath (Hanil Science, HA-35) for 10 minutes, subjected to a primary cooling at room temperature (25° C.) and a secondary cooling at 5° C. to 10° C., so that the amino acid beverage was prepared finally.
The beverages of Comparative examples and Experimental examples were prepared in respective tasting cups, and organoleptic evaluation was carried out by using a panel of 30 persons. Each tasting cup was given a random number to exclude the prejudices of the organoleptic panel, and the off-taste, off-odor, acridity, and overall preference were measured. Herein, the off-taste, off-odor, acridity, and overall preference were expressed as the values of 1 to 5, and the higher the organoleptic intensities of the off-taste, off-odor, and the acridity, the larger the expressed values thereof, and the better the overall preference, the larger the expressed value.
As a result, in Experimental examples 5 to 16, it was found that the intensities of off-taste, off-odor, and acridity were reduced, and the overall preference was significantly improved, compared to Comparative example (arginine organoleptic evaluation of Table 4, methionine organoleptic evaluation of Table 5, ornithine organoleptic evaluation of Table 6, and citrulline organoleptic evaluation of Table 7). Therefore, it was found clearly that allulose was added to beverages containing amino acids so as to relieve the off-taste, off-odor and acridity, and enhance the overall preference.
In order to characterize amino acid beverages, the pHs and acidities of Experimental examples were measured. The pH was measured using a pH meter (Mettler Toledo, Seven compact). The acidity was obtained by titrating the sample (s) of each Experimental example weighted (Mettler Toledo, New Classic ML model) with 0.1 N NaOH standard solution (Daejung Chemicals & Metals Co., Ltd.), measuring a NaOH titer (V) at the time point when the pH reached 8.1, and substituting the weight value of the sample (s) and the NaOH titer value (V) into [Equation 1] below to yield the acidity.
Acidity=0.6404*V/s [Equation 1]
(wherein *0.6404 is the amount (g) of citric acid corresponding to 1 mL of 0.1 N—NaOH)
As a result, it could be found that the pHs of the amino acid beverages were between 3.5 and 4.3, and the acidities were between about 0.1 and 0.15.
