| The oil-tea camellia seed oil was used as the raw material oil,the compound oleogel was prepared by adding monoglyceride and beeswax. The effects of dosage of compound gel agent, mass ratio of monoglyceride to beeswax, heating temperature and heating time on the oil holding capacity of compound oil-tea camellia seed oil oleogel were investigated. Based on the single factor experiment, the Box-Behnken experimental design methodology was used to optimize the test conditions, and the property of compound oleogel system was analyzed.The results showed that the optimal preparation conditions of compound oleogel were obtained as follows: dosage of compound gel agent 9.9%, mass ratio of monoglyceride to beeswax 4∶ 6, heating temperature 71 ℃, heating time 47 min. Under the optimal process conditions, the oil holding capacity of the compound oleogel reached 98.70%, and three crystal forms of α, β and β ′ were in the oleogel system.Compared with the single oleogel, the compound oil-tea camellia seed oil oleogel had better oil holding capacity and moderate hardness. |
