Embodiment

[0069] like Figure 7 As shown, the motion parameters of the linear driver, the rotary driver and the transmission flow rate of the artificial saliva are respectively set in the controller and the cooperation between them is guaranteed.

[0070] (1) Preparation of artificial saliva: first prepare artificial saliva electrolyte solution, wherein the concentration of inorganic salts is 12.16mmol / L KCl, 2.96mmol / L KH 2 PO 4 ,1.09mmol / L NaHCO 3 ,0.12mmol / L MgCl 2 (H 2 O) 6 ,0.048mmol / L(NH 4 ) 2 CO 3 and 0.15mmol / L CaCl 2 . Dissolve salivary amylase in this electrolyte solution to achieve an enzyme activity of 75 U / ml. Pour the prepared 30mL artificial saliva into the artificial saliva storage container and store it in a water bath control system at 37°C and heat it to a constant temperature state of 37°C.

[0071] (2) Set the execution parameters of the controller of the drive motor in the upper control computer: translate 10mm in the direction of the food baffle, and th...

Abstract

The invention discloses a bionic oral cavity food processing system and method. The system comprises a controller, a bionic oral cavity chewing device (1), and a saliva fed-batch device (2). The bionic oral cavity chewing device (1) and the saliva fed-batch device (2) are electrically connected to the controller. The saliva fed-batch device (2) is connected to the bionic oral cavity chewing device(1) through a conveying pipe (3). The controller controls the saliva fed-batch device (2) and then artificial saliva is gradually injected to food in the bionic oral cavity chewing device (1). In theinvention, the saliva fed-batch device is added in the bionic oral cavity food processing system, the physical and chemical digestion processes of food during an oral cavity chewing process are simulated, and the two processes of the physical breaking of solid food structures in a bionic oral cavity and the intake of the artificial saliva are truly simulated so that an in-vitro oral cavity processing method is closer to a real human chewing process. The system and the method are used to study changes from the food to bolus during the chewing process and accurate data is provided for a test.

Description

technical field [0001] The invention belongs to the field of in vitro digestion simulation, and more specifically relates to a bionic oral food processing system and a method thereof, which can be used to extrude, grind and mix with saliva in the oral cavity of various types of solid food in vitro bionic the process of. Background technique [0002] Oral processing, also known as chewing, is the first stage of digestion in humans. The oral processing of solid food usually involves the following two main physicochemical changes: [0003] (1) The structure of the food itself is broken and decomposed into small particles due to the mechanical processing of extrusion, shearing and grinding from the teeth and palate, reaching a size that is safe to swallow; [0004] (2) The continuous secretion and addition of saliva increases the water content of the food bolus, softens the texture of the food bolus, and further ensures safe swallowing. [0005] During oral processing, food i...
