Myrtle ketone microcapsule for promoting animal growth and application thereof

The invention discloses a myrtle ketone microcapsule for promoting animal growth and application of the myrtle ketone microcapsule. The preparation method comprises the following steps: selecting zein and maltodextrin as microcapsule wall materials, citric acid as a cross-linking agent and myrtle ketone as a core material, adding food-grade glycerol monocaprylate and sucrose fatty acid ester as an emulsifier and a plasticizer, and performing spray drying by using a spray dryer to obtain the myrtle ketone microcapsule. Through citric acid crosslinking, the stability of the core-shell structure microcapsule constructed by zein and maltodextrin is greatly improved. The encapsulation rate is improved, the storage stability is improved, the intestinal accessibility rate is improved, and the like.
