Description

The present invention relates to a nutritional supplement composition, a method for producing the same, a method for suppressing unpleasant odor of a nutritional supplement composition, and a composition for suppressing unpleasant odor of a nutritional supplement composition.

In recent years, with irregular eating habits and increasing awareness of beauty, nutritional supplement compositions such as nutritional supplements and supplements containing nutrients such as amino acids, vitamins, and minerals have been developed to efficiently supply necessary nutrients. demand is increasing.

The nutritional supplement composition contains various ingredients (hereinafter sometimes referred to as "raw materials"), and some of the raw materials themselves may have an unpleasant odor. Are known. Such odor poses a problem in that it reduces the product value of the nutritional supplement composition.

For example, vitamin B1 is known as a component that causes a problem with the odor of the raw material itself.
