Ingredient delivery refers to the process in which catering companies or meal delivery services supply various ingredients, including vegetables, fruits, agricultural products, and even meats and frozen foods, to enterprises such as schools, restaurants, and hotels in need of ingredients. This service is typically handled by ingredient delivery companies or individual entrepreneurs, who purchase the ingredients from various suppliers and then transport them to various locations, including schools, canteens, hotels, restaurants, and communities, providing a social and commercial service.

Primarily, it's about meeting customer demands and promptly delivering the required ingredients to their hands. Particularly, the canteen delivery model has brought immense convenience to the majority of canteens, eliminating the need for self-purchasing.
