Relationship between the amount of glucose eluted during chewing ofgummy jelly and masticatory value obtained using the sieving method

<p>The purpose of this study was to clarify the relationship between the amount of glucose eluted during chewing of gummy jelly and masticatory value obtained using the sieving method. In total, 206 healthy adults participated in this study. The amount of glucose eluted when participants chewed gummy jelly for 20 s and masticatory value when participants chewed 3 g of peanuts 20 times were calculated. To determine the amount of glucose eluted, the participants were asked to hold 10 mL water in their mouths and spit it out into a cup with a filter after chewing; after this, the glucose concentration in the filtrate was measured. For the masticatory value, the participants were asked to spit into a 500 mL beaker after chewing; the chewed peanuts were then sifted through a 10-mesh sieve under running water. The peanuts remaining on the sieve were dried and weighed. From this residual value, the amount of peanuts and weight percentage that passed through the sieve were calculated. First, the amount of glucose eluted and masticatory values were compared between men and women. Next, the relationship between the amount of eluted glucose and masticatory value was investigated separately for men and women. Both the amount of glucose eluted and masticatory value were significantly higher in men than those in women, and a significant difference was observed between the two. Regarding the relationship between the amount of glucose eluted and masticatory value, the multiple correlation coefficient and coefficient of determination were larger in curve regressions, such as quadratic and logarithmic curves, than those in linear regression, for both men and women. These findings suggested that there was a significant relationship between the amount of glucose eluted and the masticatory value, and that curve regression was more suitable than linear regression.</p>
