Definitions
- the present invention relates to tea drinks and health drinks to which dipeptide iso- mouth isyl tyrosine (Ile-Tyr) or a substance containing iso-mouth isyl tyrosine (excluding the extract of fruit body of B. aeruginosa) is added. And other functional beverages.
- Dipeptide iso- mouth isyl tyrosine Ile-Tyr
- a substance containing iso-mouth isyl tyrosine excluding the extract of fruit body of B. aeruginosa
- beverages containing dipeptides include hydrated colloidal polysaccharides (eg, xantham gum, pectin), saccharin salts, and diptide sweeteners (eg, aspartyl phenylalanine methyl ester).
- colloidal polysaccharides eg, xantham gum, pectin
- saccharin salts e.g., aspartyl phenylalanine methyl ester
- Beverage composition JP-A-6-90721
- strong cadibatide sweetener Hi-I-L-aspartame-L-L-phenylalanine methyl ester
- sodium carboxymethylcellulose dextran, algin, gum arabic
- a storage fluid containing a stabilizing fluid consisting of carrageenan, xanthan gum, guar gum, hydroxy-propylmethylcellulose, methylcellulose, pectin, locust bean gum, sodium alginate, propylene glycol alginate, ramamel and mixtures thereof.
- Stability, aqueous sweetener suspension, etc. (W_ ⁇ 9 5Z 1 5 6 9 7, WO 9 5/1 7 1 0 4) are known.
- isoleucyl thycin is a known dipeptide having angiotensin I converting enzyme (ACE) inhibitory activity.

Although it is a beverage, it is also nutritionally useful. Isoleucine-tyrosine is an essential amino acid and is nutritionally essential. In particular, tyrosine is a precursor of neurotransmitter and essential for maintaining brain function. However, isoleucine monosaccharide was not suitable as a beverage material because of its bitter taste. In contrast, iso-isyltyrosine has no bitter taste and does not precipitate, which is a major problem in beverages.

- Purification and identification of the following blood pressure lowering substances are basically based on the blood pressure lowering effect of SHR, but the ACE inhibitory activity, which is relatively easy to measure due to the mechanism of action of the blood pressure lowering substance, is also an auxiliary index.
- the second fraction (B) which has the highest SHR blood pressure lowering activity, was collected, concentrated on a rotary evaporator and filtered, and then an 8% acetonitrile solution containing 0.1% TFA was added.
- the eluate was supplied to preparative HPLC. 100 LL of each fraction (3.5 mL) collected was dried with a centrifugal concentrator, and the ACE inhibitory activity was measured. The results are shown in Figure 3. As shown in FIG. 3, several peaks indicating ACE inhibitory activity were obtained. Isocratic HPLC, which was used as an eluent for the peak showing the strongest activity, was renecked twice to obtain a single peak.
- the third peak (C) of gel filtration which showed weak activity in in vivo, was concentrated and then subjected to the recrystallization of isocratic HP LC of 8% acetonitrile containing 0.1% TFA.
- ACE inhibitory activity was measured for the fractions.
- Fig. 4 shows the results. As shown in FIG. 4, three peaks showing ACE inhibitory activity were obtained, and amino acid sequence analysis was performed. From the two fractions, isoloisyl tributophan (Ile-Trp) and The presence of Rilto Livtojuan (Val-Trp) was estimated. The remaining fraction contains alanyl tributofan (Ala-Trp) and glycyltributophan.
- Ile-Tyr The content of each peptide estimated from ACE activity was 5.4, 9.2, 1.6 ugZg dry powder for Ile-Tyr, Ile-Ti'p and Val- Val ⁇ ' ⁇ , respectively.
- Ile-Tyr was scarcely detected in shiitake mushrooms and mushrooms, which are representative mushrooms and have reported hypotensive effects.
- Ile-Tyr was identified as a substance having a blood pressure effect on SHR from the hot water extract of the fruit body of B. agaricus. At the same time, dipeptides containing five tryptophan were obtained, but when administered orally to SHR, the effect was not as low as Ile-Tyr.
- dipeptides containing tryptophan which have stronger ACE inhibitory activity than Ile-Trp, Val-Trp, etc., are less effective at in vivo than Ile-Tyr.
- Ile-Tyr is not detected in such species as Shiitake-maitake, and it is not present in any mushrooms, and the mechanism of generation of these Ile-Tyr is interesting. In general, it is thought that the protein is produced by the action of the protease on the precursor protein.

- Reference sample aqueous solution The reference sample aqueous solution in which 50 g of the above Ile-Tyr-containing reference sample was dissolved in 100 mL of tap water was brown and transparent, had a tasteful taste, and was evaluated as preferable as a beverage. .
- golden katsura tea without Ile_Tyr was found to precipitate by standing at 37 ° C for 1 week, and fading was observed 1 week after sunlight irradiation.
- 1 g of the above Ile-Tyr standard 1 g of the above-mentioned lie standard or 1 g of the above-mentioned Tyr standard was added, and both lie-added golden katsura tea and Tyr-added golden katsura tea were light brown and transparent. However, it was bitter and not suitable for drinking.
- the golden katsura tea with the lie-Tyr-containing material to which the above reference sample lg was added in place of the above 1 g of Ile-Tyr standard was not only light brown and transparent, had the original flavor, but also had a rich body The taste was increased, and the beverage was evaluated as favorable. No precipitation was observed even after one week at 37 ° C, and no fading was observed even after one week of irradiation with sunlight.
- the lie-Tyr-containing health drink to which 1 g of the above-mentioned reference sample was added instead of the 1 g of the lie-Tyr preparation described above was not only light-brown and transparent and had an original flavor, but also a rich body and body.
