JPH04237475A - Sweetener containing theanderose - Google Patents

Abstract

PURPOSE:To enhance degree of sweetness by adding sodium L-glutamate to theanderose. CONSTITUTION:In a sweetener containing theanderose, sodium L-glutamate as a substance for enhancing degree of sweetness is added to the sweetener to give a sweetener having higher degree of sweetness than one comprising theanderose alone, showing high-quality sweetness and palatability close to sugar.

Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention has good sweetness quality,
This invention relates to a theanderose-containing sweetener that has palatability comparable to products using sugar.

0002

[Prior Art] Sucrose has been a typical sweetener since ancient times, and its excellent sweetness is unrivaled. However, sucrose has the disadvantage of causing tooth decay. This drawback has become more acutely recognized in recent years, and as a result, interest in low-cariogenic sweeteners to replace sucrose has increased. Synthetic sweeteners are also available as this type of sweetener, but they have safety issues, and even if there is no problem, consumers have a strong tendency to dislike them psychologically, so glycyrrhizin Naturally derived products such as , stevioside, and fructooligosaccharides are attracting attention. However, these sweeteners are inferior to sugar in terms of taste quality and the like. For example, although glycyrrhizin has a sweetness level 50 to 100 times higher than that of sucrose, and 250 times higher in pure form, it has the disadvantage that its sweetness is delayed and leaves an unpleasant aftertaste.

[0003] Among the various low-cariogenic sweeteners, theanderose is characterized as a sweetener that is neither bitter nor unpleasant and can replace sucrose, but it has a weak sweetness and is therefore comparable to sucrose. The disadvantage is that a larger amount must be added to obtain the sweetness.

0004

[Problems to be Solved by the Invention] The present invention addresses the above-mentioned problems when using theanderose as a sweetener, namely, the sweetness of theanderose is weaker than that of sucrose. The object of the present invention is to provide a theanderose-containing sweetener that is comparable to sucrose by giving a feeling of lack of sweetness to these users and improving the reduced palatability of theanderose in these users.

[0005] The theanderose mentioned here is a trisaccharide having the structure shown below.

[Means for Solving the Problems] As a result of extensive research into solving the problems with the theanderose-containing sweeteners, the present inventors found that when theanderose is used in combination with monosodium L-glutamate, good sweet taste quality is achieved. However, the present invention was completed based on the knowledge that the sweetener has a high palatability similar to that of sucrose.

That is, the present invention is a sweetener containing theanderose, which is characterized by containing monosodium L-glutamate. Theanderose, which is an essential component of the present invention, constitutes all or part of the sweetener. When used in combination with other sweeteners, the sweeteners to be combined include sucrose, glucose, fructose, high fructose sugar, sorbose, other sugars, sugar alcohols such as sorbitol and maltitol, other sugars, and natural sugars such as saccharin, aspartame, and stevioside. Or you can use any artificial sweetener.

[0009] The concentrations of theanderose and monosodium L-glutamate vary depending on the type of target product and other raw materials used in combination, and the optimum concentration can be set each time, but specifically, for example, In tabletop sweeteners, when theanderose is used at a concentration of 5 g/dl, monosodium L-glutamate is used at a concentration of 0.00.
Good results can be obtained by blending at a concentration of 0.05 to 0.1 g/dl.

[0010] Furthermore, it is of course possible to add any raw material components other than those exemplified above without departing from the purpose of the present invention.

【Example】

0012

[Example 1] L-glutamate monosodium 0.5g/
dl, 0.05 g/dl or 0.005 g/dl, and theanderose 5 g/dl, 3 g/dl-containing aqueous solutions were prepared. The sweet quality of each sample obtained was sensory evaluated by eight taste panels. As a result, when the monosodium L-glutamate concentration was 0.5 g/dl, the taste of monosodium L-glutamate was strong and it was inappropriate to use it as a sweetener.
/dl had a richer sweetness and superior sweetness than the theanderose alone.

[0013] The sweetness level of theanderose alone is 5.
The case where the concentration of g/dl is used is set as 1, and compared with the case where the concentration of theanderose is sequentially increased, the magnification of the concentration is shown which the panelists judged to be closest in sweetness.

[0014]

[Example 2] Theanderose
5g/dl Monosodium L-glutamate 0.
When one black tea bag purchased from Nitto Black Tea was added to 100 ml (60°C) of an aqueous solution containing the above two components, as shown in Table 2, the sweetness was superior to that of theanderose alone.

[0015]

[Example 3] ■ Theanderose
5g/dl Monosodium L-glutamate 0.05g
/dl■ Cane sugar
5g/dl When the two types of aqueous solutions mentioned above were evaluated by a panel of 8 people, the one using theanderose and monosodium L-glutamate was found to be richer than the one using sucrose.
, favorable results were obtained in terms of "thickness".

EFFECTS OF THE INVENTION By containing theanderose and monosodium L-glutamate, the present invention makes it possible to express a high-quality sweet taste and to obtain a sweetener having a palatability closer to that of sugar.
