Bioactive substances possess superior antioxidant, anti-hypertensive, and anti-tumor activities. However, their susceptibility to degrade at low pH often limit their application. Compare with the conventional oil-in-water (W/O) emulsions, the lack of natural hydrophobic stabilizers resulted in difficulties in fabricating water-in-oil (W/O) high internal phase emulsion (HIPE). Further, the instability of W/O HIPE also limit its industrial application in food industry. In the present study, a natural, conventional, eco-friendly, and structured W/O HIPE was developed using glyceryl monostearate (GMS) as emulsifier and beeswax and gellan gum as structurant. The system with the synergetic effect of emulsifier and structurant, accounted for 0.25 wt % of GMS and hydrogel, and 1.25 wt % of beeswax in total system endowed the W/O HIPE with biphasic rigid network and impressive storage stability. The microstructures of these newly developed W/O HIPEs could be controlled by the beeswax concentration (cb), GMS concentration (cg), and aqueous phase volume (Φ). Moreover, the GMS-based emulsion encapsulation improved the retention rate of betanin by 36.68% after 7 days of storage. Meanwhile, this emulsion gel could prevent the nucleophilic attack of hydrogen ions against betanin at room temperature under a low pH environment, which greatly improved the stability of betanin under highly acid conditions. Furthermore, the GMS stabilized W/O HIPE possessed pH-sensitive, which could achieve controlled-release of both hydrophilic and hydrophobic functional compounds in an in vitro simulated release assay. This study involved multiple reactions and reactants, such as Glyceryl monostearate (cas: 31566-31-1COA of Formula: C21H44O5).
Glyceryl monostearate (cas: 31566-31-1) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits, including apples, durians, pears, bananas, pineapples, and strawberries. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.COA of Formula: C21H44O5
