The big data technology indicates that we can obtain the valuable information from data with different analysis methods and tools. The artificial intelligence refers to develop and research the theory and method to mimic or expand the intelligence of humans. Big data technology and artificial intelligence technology complement each other. Big data is the cornerstone of artificial intelligence， and artificial intelligence is the applications of big data. Big data and artificial intelligence of the food science are the intersection of big data technology， artificial intelligence technology and food science. The integration of artificial intelligence and big data technology into the field of traditional food science creates new recipes and intelligently recommend， tracks and traces food， analyzes user taste preferences and monitors food safety， etc.， so that food science obtains greater development and provide the better service for humans. This paper demonstrates the current developing status of the intersection of big data and artificial intelligence in the food field， analyzes the challenges when applying the big data and artificial intelligence into the food domain， discusses feasible solutions， and does looking forward to the future development trend of big data and artificial intelligence in food science. The purpose of this article is to attract more integration of big data and artificial intelligence technology with food science， and to improve food science development according to the direction of food science to provide better service for the people.
