Description

Technical Field

[0001] The invention relates to the technical field of simulated digestion and decomposition devices, and in particular to a simulated digestion and decomposition device for functional food. Background Art

[0002] The primary function of functional food is nutrition. The second function is to provide sensory enjoyment when used, that is, to increase appetite by using the color, aroma and taste of food. The third function is to regulate the physiological activity of the human body. The ingredients in functional foods that truly play a physiological regulatory role are called physiologically active ingredients or functional factors. There are hundreds of varieties and eight major categories, namely functional sweeteners, active oligosaccharides, active polysaccharides, active oils, biological antioxidants, active peptides, active proteins, lactic acid bacteria and other active ingredients. With the continuous deepening of research, new functional factors are still being discovered. In order to better carry out research on functional foods, a functional food simulation digestion and decomposition device is proposed to realize the intuitive study of the digestion and decomposition state of functional foods.

[0003] After searching, a Chinese patent with publication number CN113744610A published on December 3, 2021 discloses a simple in vitro dynamic simulated digestion device and a method of use, which is roughly described as comprising a simulated oral portion, a simulated stomach portion, and a simulated small intestine portion connected in sequence, a first bracket, a second bracket, and a third bracket are arranged inside the incubator, the simulated oral portion is an oral reaction bottle, and the oral reaction bottle is suspended under the first bracket, the simulated stomach portion is composed of a gastric juice storage bottle and a gastric reaction bottle, wherein the gastric reaction bottle is suspended under the second bracket, the gastric juice storage bottle is connected to the bottom of the first bracket, and the gastric reaction bottle and the gastric juice storage bottle are connected to each other. The storage bottle is connected to the stomach reaction bottle, and the simulated small intestine part is composed of a bile storage bottle, a pancreatic juice storage bottle and a small intestine reaction bottle, wherein the bile storage bottle and the pancreatic juice storage bottle are vertically hung under the second bracket, and the small intestine reaction bottle is vertically hung under the third bracket. The stomach reaction bottle, the bile storage bottle, the pancreatic juice storage bottle and the small intestine reaction bottle are connected. When in use, before simulating digestion, turn on the thermostat and adjust the temperature to 37°C. After the temperature stabilizes, mix the simulated saliva, CaCl2(H2O)2 solution and distilled water and add them to the oral reaction bottle from the injection port, and then add the simulated gastric juice, CaCl2(H2O)2 solution, HCl solution and distilled water. After mixing, add the simulated bile from the simulated bile inlet to the bile storage bottle and the small intestine reaction bottle respectively from the simulated pancreatic juice inlet and the bile-pancreatic juice mixed liquid inlet. Connect all components and control switches to the off state. Reaction stage: add salivary amylase solution and the sample to be digested from the injection port to the oral reaction bottle, add pepsin and gastric lipase solutions from the first simulated gastric juice inlet to the gastric juice storage bottle, and add After the sample is digested, immediately turn on the first control switch, the second control switch, and the first peristaltic pump and adjust the flow rate. After turning on the first control switch, the oral digestion sample enters the gastric reaction bottle from the oral digestion sample outlet through the oral digestion sample inlet. After 5 minutes, add pancreatic enzyme from the simulated pancreatic juice inlet to the pancreatic juice storage bottle. Turn on the third control switch, the fourth control switch, the fifth control switch, and the second peristaltic pump and adjust the flow rate. After turning on the third control switch, the gastric digestion sample enters the intestinal reaction bottle from the gastric digestion sample outlet through the gastric digestion sample inlet. After 2 hours, turn on the sixth control switch and take samples from the intestinal digestion sample outlet for subsequent testing and analysis.

[0004] Although the above-mentioned existing technical scheme can preliminarily realize the dynamic simulation digestion of food, its overall structure is realized by multiple bottles, so there is a big gap with the actual organs in the human body, especially the replacement organs such as the small intestine reaction bottle. The total length of the small intestine in the human body is about 4-6 meters. These 4-6 meters of small intestine can play the role of secreting body fluids, and the range of action of a single small intestine reaction bottle is small. At the same time, whether it is the oral cavity, stomach or intestinal system, the corresponding body fluids are secreted evenly, and it is not like a single pipeline input. Therefore, the above-mentioned technical scheme as a whole is quite different from the actual situation, and the reliability of the data collected in the experiment is poor. Summary of the invention

The drive motor, the electric push rod, the first peristaltic pump and the second peristaltic pump are all mature products selected on the market according to the use needs and installation space. This part only uses them and does not make any improvements to their structure and principle. At the same time, each of them is equipped with an instruction manual and manufacturer's technical support, so I will not go into details about this. Corresponding body fluids are added to the oral fluid cylinder 4, the gastric fluid cylinder 9 and the intestinal fluid cylinder 14.
