Abstract

In this study, the nettle extract (NE)-loaded nanoliposomes (NLPs) were spray-dried with maltodextrin and was used to fortify and extend the shelf life of the cake. The particle size and zeta potential of the reconstituted spray-dried NE-loaded NLPs were 269.4 ± 14.2 nm and − 20.7 ± 4.6 mV respectively. The encapsulation efficiency values of non-dried NLPs and the reconstituted spray-dried NLPs were 87.0 ± 5.3 and 75 ± 4.7%, respectively. The produced NLPs samples were added at three different concentrations of 0, 5, and 7.5% w/w in the cake. The pH and water activity of cakes showed no significant (p > .05) change by the addition of NLPs samples. The fortified cake with 7.5% of spray-dried NLPs exhibited the highest total phenolic content and DPPH scavenging activity. The yeast and mold count in the fortified cakes with spray-dried NLPs showed no significant difference compared with the cake containing potassium sorbate during 28-day storage.

Novelty impact statement

The application of natural additives can be suitable alternatives to synthetic additives in foodstuffs such as bakery products. The nanoliposomes loaded with natural additives have not been considered for fortification and to extend the shelf life of the cake. In this regard, this study aimed to spray drying of NE-loaded NLPs by maltodextrin and application of this nanocarrier as a natural additive in cake formulation.
