Embodiment 1

[0107] 10 g of pandan leaves (commercially available) were used as a plant material, and 50 g of pH 7 phosphate buffer was added. After stirring at room temperature for 1 hour, MCT (caprylic acid / capric acid triglyceride, MCT having a carbon number C6:C8 ratio of 6:4) was added as an edible oil, and extraction was performed while stirring at room temperature for 30 minutes. Using the obtained oil layer as a plant extract, it was confirmed by gas chromatography that 2-acetyl-1-pyrroline was contained.

Abstract

In order to use 2-acetyl-1-pyrroline as a perfume material, the present invention relates to a method in which 2-acetyl-1-pyrroline is present stably for a long period of time and the characteristic aroma of 2-acetyl-1-pyrroline is sustained. According to the present invention, by combining 2-acetyl-1-pyrroline with one or two edible oils selected from the group consisting of triesters of medium-chain fatty acids and glycerol (MCT) and glycerol triacetate, it is possible to stabilize the presence of 2-acetyl-1-pyrroline, thereby maintaining the characteristic aroma of 2-acetyl-1-pyrroline and improving the quality of 2-acetyl-1-pyrroline. Therefore, the compound can be suitably used as a perfume material for various products.

Description

technical field [0001] The present invention relates to a plant extract comprising 2-acetyl-1-pyrroline and a method for producing the same. In addition, the present invention relates to a composition comprising 2-acetyl-1-pyrroline and a specific edible oil. The present invention further relates to a fragrance composition comprising the above-mentioned plant extract or the above-mentioned composition, and various preparations comprising the above-mentioned fragrance composition. In addition, the present invention relates to a stabilization method of 2-acetyl-1-pyrroline. Background technique [0002] 2-Acetyl-1-pyrroline is known as an aroma component contained in the aroma of grains such as rice or processed meat (J. Agric. Food Chem., 1993, 41, 1458-1461, Non-Patent Document 1). This compound has a very characteristic aroma of popcorn-like and a very low threshold value, and is therefore attracting attention as a flavoring material that can be used in foods and the like...
