To investigate the effects of added vitamins and minerals on the stability of full-nutrition,foods-for-special-medical-purposes emulsions based on peanut oil bodies.
Prepared a peanut oil body-based, full-nutrition, foods-for-special-medical-purposes emulsion with an energy density of 1.0 kcal/mL using the natural emulsifying structure of peanut oil bodies, and evaluated the effects of vitamins and minerals on emulsion stability by particle size, zeta potential and multiple light scattering analyses, as well as examined changes in stability and appearance quality of each emulsion group before and after sterilization.
The addition of vitamins or minerals did not induce obvious heat-induced aggregation in peanut oil body emulsions; in particular, in the vitamin-fortified group, the droplet size increased by only 0.49% after sterilization. Emulsions with added minerals exhibited good storage stability, with creaming index values after 7 d of storage all below 1.0%. However, after sterilization, emulsions containing minerals showed a pronounced change in color (ΔE*>20), which had a certain impact on sensory quality.
The vitamin-and mineral-enriched peanut oil body-based complete nutritional emulsion for special medical foods exhibits exceptional stability, providing a reference for the processing and utilization of oil body-based in FSMP foods.
