Two types of hydrocolloid gels with similar fracture loads were prepared.
•
Electromyography was measured during free-eating of 3–24 g mouthful gels.
•
Oral processing times and numbers of chews were similar for both gels.
•
These variables were proportional to 0.7 of the power of mouthful mass of gels.
•
Mastication and swallowing efforts depended on gel types.
