[Problem] The present invention addresses the problem of providing a method for manufacturing a variety of seasoning ingredient liquids having a high extract solids content, the method making it possible to prevent a decrease in collection rate due to burning and quality degradation due to microbial contamination while improving productivity through a continuous heating process performed for a short period of time, and to impart superior flavors and impart flavors in a more versatile manner while inhibiting the destruction of taste-contributing components. [Solution] As a result of thoroughgoing investigations into solving the above problem, the inventors of the present invention perfected the present invention upon discovering a method for manufacturing a seasoning in which a direct steam-heating cooker is used, whereby a desired flavor is imparted in a mild manner within 60 seconds while a continuous heating treatment at 130 C. or above is performed, and destruction of taste-imparting components can be minimized.

Natural sweetener compositions are disclosed, which generally include steviol glycosides extracted from a Stevia rebaudiana plant and an amino acid component consisting of free glycine. The natural sweetener compositions may optionally further include gymnemic acid (such as an extract of a Gymnemic sylvestre herb that includes 25%-75% gymnemic acid). The natural sweetener compositions may consist essentially of those two or three componentsor may be included in beverages, beverage powders, and foods.
