As a kind of catering operation mode, the central kitchen realizes the standardization, scale, intensification and informationization of food production through the unified procurement, unified processing and unified distribution of food raw materials and the automated operation of equipment. Automated production lines synchronize production, allowing precise quantification of recipes, flavors, and batches of dishes, and precise quantification of production conditions such as temperature, heat, time, specifications, and quantities, ensuring consistency in the quality of the dishes. Spiegel Yeast Extract itself is an excellent carrier of flavor, and only a small amount is needed to bring about flavor enhancement and freshness, which helps to improve the overall freshness of the food, making it richer in texture, and achieving a 30% reduction in salt, which improves the overall flavor. It has been widely used in central kitchens for various semi-finished dishes, convenience foods, soups, sauces, seasonings and other fields.
