Preparation and property exploration of goat milk fat microcapsules with different wall material ratios
摘要
Abstract
In order to explore effective embedding technology of goat milk fat(GMF)and improve the storage quality of GMF,GMF was used as the core material,and soy bean protein isolate(SPI)and maltodextrin(MD)were used as the wall materials to prepare GMF microcapsules with different wall material ratios.The embedding rate of the microcapsules and the optimal conditions were measured.The basic physical properties(water content,water activity,solubility,particle size,color value),structure(Fourier transform infrared spectroscopy,X-ray diffraction),moisture absorption and peroxide value(POV)during storage of the optimized microcapsules were determined.The results showed that the optimum wall material ratio was mSPI∶mMD=1∶4.The water content,embedding rate,particle size and solubility of the microcapsule were 4.5％±0.4％,92.5％±1.3％,954.20±11.35 nm and 73.02％±2.90％,respectively.Fourier transform infrared spectroscopy found that C—O in the goat milk fat disappeared in the microcapsule,and the strength of C=O and—CH2 decreased slightly in the microcapsule.A new characteristic peak was found in the microcapsule by X-ray diffraction,indicating that GMF is successfully embedded in the wall material.The moisture absorption of the microcapsule was stable in the range of 11％～12％.The POV of the microcapsule increased rapidly from day 0 to day 21.In summary,a GMF microcapsule with high embedding rate,small particle size and stable properties was prepared.关键词
