A substance capable of imparting a kokumi having CaSR agonist activity is described. This substance is able to impart kokumi in a superior manner, in particular, at the initial taste, and is also highly stable and can easily be produced at a low cost. The present invention thus provides a kokumi-imparting composition which includes such a substance as well as a complex kokumi-imparting composition which includes the substance and other substances possessing the CaSR agonist activities in combination. More particularly, the present invention herein provides a kokumi-imparting composition including γ-Glu-Nva (L-γ-glutamyl-L-norvaline), and a complex kokumi-imparting composition including the foregoing substance and another substance having a CaSR agonist activity, in combination.
本发明描述了一种能够赋予kokumi的物质,具有CaSR激动剂活性。该物质能够以优越的方式赋予kokumi,特别是在初始口感方面,并且稳定性高,可以以低成本轻松生产。因此,本发明提供了一种包括这种物质的kokumi赋予组合物,以及包括该物质和其他具有CaSR激动剂活性的物质的复杂kokumi赋予组合物。更具体地说,本发明提供了一种包括γ-Glu-Nva(L-γ-谷
氨酰-L-正丙
氨酸)的kokumi赋予组合物,以及包括前述物质和另一种具有CaSR激动剂活性的物质的复杂kokumi赋予组合物。
