| Abstract: |
| Aim to improve the stability of hemp seed oil and expand its application in food industry, hemp seed oleogel was prepared using hemp seed oil as raw material, glycerol monostearate (GMS), rice bran wax (RBW), beeswax (BW), sugarcane wax (SW) and carnauba wax (CBW) as gelators. The types of gelator, the mass ratio and dosage of composite gelator were optimized by taking oil holding rate and hardness as indicators, and the microstructure, rheological properties, Fourier infrared spectroscopy (FT-IR), thermal properties (DSC analysis) and storage stability for carrying β-carotene of the obtained oleogel were characterized. The results showed that when the mass ratio of SW to RBW was 1∶ 1 and their total dosage was 8%, the hemp seed oleogel had high oil holding rate (95.04%) and moderate hardness (147.6 g), the crystal distribution of the oleogel was more uniform and the network structure was more compact, which was conducive to binding oil. Compared with 25 ℃, the oleogel system formed at 4 ℃ had higher apparent viscosity and storage modulus, and the system was more stable. FT-IR analysis showed that the oleogel system realized self-assembly or structural unit construction by intermolecular forces such as hydrogen bond and van der Waals forces. DSC analysis showed that the hemp seed oleogel system began to absorb heat and melt at 45 ℃, and began to crystallize at the same temperature in the crystallization process, indicating good thermal stability of the system. Compared with hemp seed oil, the retention rate of β -carotene in hemp seed oleogel system was higher and the degradation rate was slower, which indicated that the oleogel system could better protect oxidizable substances. To sum up, an oleogel with a stable structure, good plasticity, high oil holding rate and good protection for oxidizable substances can be prepared by using SW and RBW as composite gelator and hemp seed oil rich in unsaturated fatty acids as base oil. |
