Bread tastes delicious when it is soft, murukku (a South Indian snack that gets its name from its ‘twisted’ shape) must be crunchy, ice cream must melt in your mouth and dosa seems to be great when its soft yet a bit crispy. There are different textures available for different foods that remain standard throughout. Individuals too differ in their texture preferences. For instance, some like soft dosa while some others like it to be as crisp as possible. Flavor might occupy top spot while we savor a mouthful of a delicacy but the absence of the right texture spoils the food’s acceptability. How about eating soggy pasta or rice despite the presence of taste and flavor in these dishes? Kaju katli might be sweet and heavenly but it is never fulfilling when the mithai is too hard or too soft. Sensory properties including the presentation of the food and its texture occupy an intense role in guiding our preferences, our portion selection and our satiety after eating food.
There is no denial that difference in taste and smell preferences causes difference in liking and intake quantities but now the same might be true in the case of texture too. Some individuals don’t bother much about the texture of the food when it tastes good but there are some others who are better at detecting even minor differences in consistency. These people are not choosy, they are not fussy but its simply because their tongues can perceive particle sizes. A research team from the Penn State University tested their hypothesis on texture preference on 111 volunteers who had their tongues tested for physical sensitivity and were asked for their opinion on different chocolate textures. The researchers tested whether texture had any impact based on perception of particle size for which they used a device called as Von Frey Hairs. Participants were slit into groups based on pressure-point sensitivity-high and low acuity. This proved the existence of a significant relationship between chocolate-texture discrimination and pressure-point sensitivity for the high-acuity group on the center tongue but not on the lateral tongue. Chocolate manufacturers take utmost caution in grinding cocoa and sugar to the right particle size for optimal acceptability by consumers. Oral texture plays a critical role in differentiation chocolate quality and value based on the grittiness property that’s primarily involved in differentiating bulk chocolate from premium chocolate. This research on food texture might even help people with feeding/swallowing problems or dementia. People, kids and adults alike, with dementia often reject foods based on texture perception and a clarity regarding texture does motivate individuals to prepare more acceptable foods based on individual difference in preferences.

Food texture-firmness, crunchiness, smoothness, thickness and creaminess-can be altered to be more harder, viscous or chewier without adding calories to bring about more acceptance, reduce calorie intake and improve satiety. If your mushrooms are rubbery or your poha hard to chew there is no denial that you are not going to like it. While some might ignore this and finish off with it the same is not possible in the case of everyone and now, we know why! Its all in your tongue. Comments are closed.
