[0002] With the popularization of modern healthy eating concepts, consumers' demand for low-calorie, natural sweeteners is increasing. Traditional sugars such as sucrose, while highly sweet, are also relatively high in calories, and long-term excessive intake may increase health risks such as obesity and diabetes. Therefore, finding a natural sweetener that can satisfy the need for sweetness while possessing low-calorie properties has become an important research direction in the food industry. Organic stevia, a natural sweetener extracted from the stevia plant, is gradually gaining market favor due to its high sweetness (up to 200-350 times that of sucrose), low calorie content (only 1 / 300th that of sucrose), and good stability and safety. However, traditional stevia production processes suffer from low extraction rates, substandard purity, and high production costs, limiting its large-scale application. Therefore, to address these issues, it is necessary to develop a production system that uses organic stevia as a raw material to prepare tabletop sweeteners. Utility Model Content
