Blend whipped cream is an aerated food, which was made by base oils and emulsifiers. However, hydrogenated oils were often used as base oil, which resulted in the poor emulsion and foam stability. To address this issue, coconut diacylglyceride was employed as base oil. Results showed that emulsion and foam stability were increased by the combined use of CO-DAG and S-170. The emulsifying activity index (EAI) and emulsion stability index (ESI) of whipping cream were increased by 113.84% and 87.25%. The falling height of whipped foam was reduced by 80.00%, and the firmness was enhanced by 16.13%. However, coarse crystals were formed by monoacylglycerols, whereby the whipped foam rate was increased but foam stability was decreased. Crystallization was delayed and network structure was weakened by SSL. The coexistence of proteins and emulsifiers in the interfacial membrane was induced by Span-60, resulting in poor stability.
