Definitions
- the present invention relates to foods and beverages containing 2,5-piperazinedione,3,6-bis(phenylmethyl)-,(3S,6S)—, and more particularly relates to extracts and beverages containing 2,5-piperazinedione,3,6-bis(phenylmethyl)-,(3S,6S)— at a high concentration, wherein the pH is 5 or more.
- Dipeptides composed of two amino acids attached to each other has received attention as a functional substance.
- Dipeptides can be designed to have additional physical properties and/or new functions, which cannot be seen in single amino acids, and hence they are expected to be applicable to a wider range than that of amino acids.
- the inventors of the present invention have found that a 2,5-diketopiperazine derivative, i.e., 2,5-piperazinedione,3,6-bis(phenylmethyl)-,(3S,6S)— (CA Registry Number: 2862-51-3) (hereinafter referred to as “compound A”) has an improving effect on learning motivation (the co-filed patent application: Japanese Patent Application No. 2009-296164).
- Products known to contain compound A include chicken extracts in liquid form which are obtained by decocting meat of livestock, as well as chicken consomme and the like in solid form.
- compound A is hardly soluble in water and hence cannot be simply added as such when attempting to incorporate compound A, which is a useful substance with an improving effect on learning motivation, into beverages at a high concentration and in an easy-to-ingest form.
- the present invention aims to provide an extract or beverage containing compound A, which is a useful substance with an improving effect on learning motivation, in an easy-to-ingest form and at a high concentration.
- extracts and beverages which not only contain compound A at a high concentration but also have low Bx values and which are good in flavor and feeling on the tongue and further have a good appearance. This success led to the completion of the present invention.
- the present invention is directed to [1] to [15] shown below.
- the extract according to [3] above, wherein the naturally occurring product is meat of livestock or poultry, fish meat, or shellfish meat.
- the extract according to [3] or [4] above, wherein the naturally occurring product is chicken meat.
- a dried extract obtainable by drying the extract according to any one of [1] to [5] above.
- a capsule or tablet encapsulating the extract according to any one of [1] to [5] above or the dried extract according to [6] above.
- a beverage obtainable by addition of the extract according to any one of [1] to [5] above.
- the beverage according to [8] or [9] above which contains compound A in an amount of 60 ⁇ g/100 g or more.
- a packaged beverage wherein the beverage according to any one of [8] to [10] above is packed in a container.
- a process for producing the extract according to [1] above which comprises:
- the present invention provides extracts and beverages, in which compound A having an improving effect on learning motivation and being highly safe without side effects can be contained at a high content with Bx values remaining low.
- the extracts of the present invention can be added to beverages and so on without impairing the taste inherent to foods and beverages.
- the extracts or beverages of the present invention, as well as foods and beverages comprising the same can be ingested continuously over a long period of time as foods and beverages useful for improvement of learning motivation.
- FIG. 1 shows the test results of whether the ingestion of a test sample reduces the time required for mice to find out an escape platform when repeating the test.
- FIG. 2 shows the test results of whether the ingestion of a test sample reduces the time required for mice to find out an escape platform when repeating the test.

- the present invention is directed to an extract or beverage containing compound A, in which the concentration of compound A can be increased even at a low Bx value.
- an extract or beverage can be prepared, for example, by the production process shown below:
- a preferred starting material used in the above pretreatment step (1) is a naturally occurring product from which compound A, a useful component, can be efficiently obtained, particularly meat of livestock or poultry, fish meat, or shellfish meat.
- meat of livestock or poultry include meat of livestock, i.e., cattle, pig, horse, sheep or goat, meat of non-livestock animals such as wild boar or deer, meat of poultry, i.e., chicken, turkey, quail, domestic duck or crossbred duck, as well as meat of non-poultry wild birds such as wild duck, pheasant, sparrow or thrush.
- meat of poultry i.e., chicken, turkey, quail, domestic duck or crossbred duck
- meat of non-poultry wild birds such as wild duck, pheasant, sparrow or thrush.
- fish meat and shellfish meat which are eaten in the course of a normal diet.
- plant materials such as coffee and cocoa can also be used.
- chicken meat is preferred for use because compound A can be
- any treatment for reducing water-soluble proteins contained in a starting material may be performed, for example, by boiling in water at 100° C. to 160° C. for 30 minutes to several hours (preferably about 3 to 8 hours, more preferably about 3 to 4 hours).
- a heating device e.g., a pressure cooker, an autoclave and so on can be combined for use depending on the intended conditions.
- an additional liquid e.g., water
- an additional starting material may further be added to adjust the concentration of an extract or beverage.
- the heating step (2) is preferably accomplished at a high temperature under a high pressure (100° C. or more and 1 atm or more), for example, at 100° C. or more, and more preferably at 125° C. or more.
- the heating time in the heating step (2) preferably ranges from 30 minutes to several hours, more preferably from about 3 to 7 hours.
- a heating device a pressure cooker, an autoclave and so on can also be combined for use depending on the intended conditions.
- the pretreatment step (1) and the heating step (2) may be performed continuously as a single step without liquid replacement.
- the pretreatment step may be followed by removal of the pre-treated meat and then replacement of the liquid before the meat is subjected to the heating step. Since samples with lower Brix values can be obtained when liquid replacement is performed after the pretreatment step (1) and before the heating step (2), it is more desirable to use liquid replacement.
- the concentration step so as to enrich compound A it is also more desirable to use liquid replacement between the pretreatment step (1) and the heating step (2) because good results will be obtained in terms of overall flavor including bitterness and slack, and the resulting samples will be less likely to affect the flavor of beverages upon addition.
- heat treatment in the steps (1) and (2) is preferably performed in a solvent in order to prevent plant and animal materials from burning.
- a solvent preferred for use include water, ethanol, or mixtures thereof. Namely, a plant or animal material containing proteins (preferably proteins rich in the contiguous phenylalanine (-Phe-Phe-) structure) is mixed with a solvent and subjected to heat treatment, followed by collection of the solvent to obtain a solution rich in compound A.
- the power of filtration in the filtration step (3) may be selected as appropriate, depending on the form of foods into which the resulting extract is incorporated, and the filtration method may also be determined as appropriate by those skilled in the art. For example, in cases where the extract is used for solid foods (e.g., tablets) and where the resulting beverages do not need to be clear (e.g., canned beverages whose appearance is hidden in containers), it is sufficient to filter off sediments and filtration through a strainer may be used for this purpose. Alternatively, in a case where the extract needs to be clear (e.g., used for beverages in transparent bottles or plastic bottles), powerful filtration should be used. For clarification purposes, filtration through a strainer may be followed by filtration through a membrane (ion exchange membrane, RO membrane, zeta potential membrane) and/or filtration through diatomaceous earth, etc.
- a membrane ion exchange membrane, RO membrane, zeta potential membrane
- this solution rich in compound A may be used directly or, if necessary, may be concentrated to further increase the concentration of compound A.

- the extract was found to cause no sediment even when added to a liquid of pH 5 or more.
- the conventionally used heating step was repeated again on a commercially available chicken extract to confirm how the content of compound A and Bx value were changed.
- the conventionally used heating step is intended to mean a heating step in a pressure cooker for household use. It should be noted that the heating temperature in such a pressure cooker is about 120° C.
- Extract 3 prepared in Example 4 above was added to prepare beverages.
- the recipe used is as shown below. Each sample was adjusted to the same Bx value of 10. When compared to the commercially available chicken extract, the starting materials prepared according to this recipe were found to have a higher compound A content even at the same Bx value and further to be excellent in flavor and appearance.
- the extract prepared in Example 4 above was lyophilized by spray drying to prepare an extract powder.
- the extract (extract 3 of Example 4; 100 g) was taken into a 200 ml recovery flask. 2. This flask was stored in a freezer ( ⁇ 18° C.) for 2 or 3 days until the extract was completely frozen. 3.
