Resumo(s): | The study assessed the effect of carrier agents maltodextrin and gum Arabic on the storage stability of spray dried Nigella sativa powder packed in low-density polyethylene bags and stored at maximum 4°C for up to 12 months. At 0, 3, 6, 9, and 12 months intervals the samples were assessed for changes in caffeine content, moisture content, water activity, colour, solubility capacity, bulk density, and antioxidants activity as total phenolic content (TPC) and total flavonoid content (TFC). After 12 months storage, a 61-68% loss in TPC and TFC was observed and anti-oxidant activity had reduced by 70%-72%. Overall, water activity and moisture content increased with a decrease in total antioxidant activity, accompanied by a significant decrease in caffeine content. No significant changes were observed in solubility capacity and bulk density of N. sativa powder. |
