[0002] Meal replacement foods refer to foods that replace part or all of a regular meal. Common forms of meal replacements include meal replacement powders, meal replacement bars, meal replacement shakes, and meal replacement porridge. In addition to being able to quickly and conveniently provide the human body with a large amount of various nutrients, these meal replacement foods are usually high in fiber, low in calories, and easy to fill up. Through sampling and testing, it can be found whether there are safety hazards such as pathogenic microorganisms, toxic and harmful substances in meal replacement foods, thereby ensuring that consumers buy safe food. Monitoring the quality of meal replacement foods can ensure that the food consumed by consumers meets nutritional and safety standards. Therefore, it is very necessary to test and sample meal replacement foods.
