Food-texture dimensions expressed by Japanese onomatopoeic words

Area of Science:

• Food Science
• Sensory Science
• Linguistics

Background:

• Understanding food texture perception is crucial for food development and consumer satisfaction.
• Onomatopoeic words offer a unique linguistic lens into sensory experiences.

Purpose of the Study:

• To identify and define the fundamental perceptual dimensions of food texture.
• To explore the relationship between Japanese onomatopoeic words and food texture characteristics.

Main Methods:

• Participants rated the texture of 56 food items using Japanese onomatopoeic words.
• Correspondence analysis was employed to extract texture dimensions from the word-food data.
• Sparse coding was used to rotate the biplot for clearer dimension interpretation.

Main Results:

• Fifteen distinct food texture dimensions were identified, including smoothness/sound, adhesiveness, crumbliness, popping/juiciness, elasticity, and crispness.
• Specific dimensions captured unique textures like those of gels, sticky foods, and even lemon and pickled plum.
• The study highlights the nuanced descriptive power of Japanese onomatopoeia for food textures.

Conclusions:

• Japanese onomatopoeic words effectively capture a wide range of basic food texture dimensions.
• This research provides a framework for understanding and utilizing onomatopoeia in food science and sensory analysis.
