Article Abstract
In order to investigate the factors affecting the release of vitamin C (VC) in gummy jelly during oral processing, four levels of gelatin (3%, 6%, 9% and 12%) were selected and a bionic chewing robot was employed in chewing experiments. Textural profile analysis showed the hardness of gummy jelly increased from 91.7 N to 198.8 N when the gelatin content was raised from 3 to 12%. Single factor chewing experiment showed that the release of VC was positively correlated with chewing frequency (F) and chewing strain (ST), while negatively correlated with gelatin content, chewing speed (SP) and volume of saliva (V). Orthogonal chewing experiment showed that the priority of the factors affected the release of VC was following: ST > F > SP > V. Multivariate linear regression analysis proposed a model to predict the amount of VC released and the goodness-of-fit of the model was 95.7%. The amount of VC released was the highest under the combination of F 12 times, ST 100%, V 2 ml and SP 40 times/min. The optimal amount of gelatin addition was 6%. This study provided an effective reference for the formula design and chewing mode optimization of gummy jelly.

Purpose: Comminution of food into small particles through mastication is important for safe swallowing. However, few studies have evaluated the functional improvement provided by newly fabricated removable dentures in terms of changes in the comminution of food at the swallowing threshold (CF-ST). This prospective cohort study aimed to clarify the changes in CF-ST associated with the fabrication of newly removable dentures.

The rheological properties and 3D printing effects of different composite gels were explored, and the results revealed that the viscosity of the peach gum polysaccharide and gelatin composite gel (PGP/GE)was moderate, and had the best 3D printing quality and stability. Using PGP/GE as the 3D printing substrate and adding five types of freeze-dried fruit powders. Strawberries, mangoes, and yellow peaches had better water binding abilities than sea buckthorn and mulberries did; as the amount of fruit powder added increased, its ability to bind water increased.

: Low masticatory function has been proposed as a risk factor for sarcopenia. This study investigated its potential association with body composition and physical performance in community-dwelling older adults. : Participants included adults aged ≥65 years (643 men; 797 women) who volunteered for a longitudinal cohort study.

This study aims to clarify whether there is a difference in masticatory performance between unilateral chewing and free chewing. The amount of glucose eluted was measured three times when 36 healthy dentate adults chewed gummy jelly for 20 s using two different chewing methods: unilateral chewing on the preferred chewing side and free chewing. The unilateral chewing cases were classified as group U (U1, U2, U3), and the free chewing cases were classified as group F (F1, F2, F3).
