Abstract

Abstract To solve the delamination & precipitation phenomena and to improve the quality of the spray-dried pumpkin powder (PP), the effects of adding mulberry leaf powder (MLP) and oat bran powder (OBP) on the PP quality were investigated. Results showed that POBP (PP + OBP, w:w = 2:1) had lower hygroscopicity (≤42.96 %), which was more homogeneous and stickiness after being brewed, effectively alleviating delamination & precipitation phenomena. Besides, PMLP (PP + MLP, w:w = 2:1) had the highest total phenolic content and total flavonoid content, with the values of 96.92 and 90.50 mg/100 g, respectively. PMLP also exhibited about ten times the antioxidant activity of PP. Furthermore, nine regression equations predicted the antioxidant properties of powders based on soluble solid values and bitterness. Overall, this study indicated that the addition of OBP and MLP improved the stability and nutritional quality of PP, respectively.
